ABSTRACT
Concern about the ozone depletion and green house effects caused by
refrigerants have initiated and continued studies into more environmentally friendly
refrigerants. This study looked into the performance of these refrigerants in terms of
second law efficiency, COP, irreversibility, and discharge temperature. A program based
on Visual Basic has been developed that can quantify the parameters above and this can
be used to guide industrialists in their efforts to build or retrofit systems with new
refrigerants. Results from the simulation have shown that R134a is potentially good as a
replacement for R12, R402a for R502, and R407c for R22.

Introduction
Chlorofluorocarbons (CFCs) are a class of chemical compounds containing
chlorine and fluorine atoms. Their wide range of industrial and consumer product uses,
however, were found to be causing significant damage to the ozone layer. Consequently,
the manufacture and use of the CFCs that were causing the most damage was phased out
through the 1990s. First discovered in 1930, a variety of CFC compounds known as
Freons (a trademark of the E. I. Du Pont Corporation) were synthesized by chemists.
Because these compounds are relatively inert (chemically stable), non-toxic, nonflammable, odourless, and inexpensive to produce, they were ideal for a variety of
applications.
CFC-11 (trichloromonofluoromethane) and CFC-12 (dichlorodifluoromethane).
Introduced in commercially in the year 1951, CFC-12 became very popular as a coolant
in air conditioners, refrigerators, freezers, and as an expander to produce tiny bubbles in
foam cups, food trays, and other products. CFCs were also used as propellants in aerosol
products, such as hair spray or paint, and to clean computer chips and medical
equipment.

1.1
Ozone depleting and global warming effects
The threat of ozone depletion and global warming is of very serious concern to
mankind. Most refrigerants in use today contribute significantly to either or both of the
effects. However, quantifying their effects is a difficult exercise with at least three main
approaches; the Ozone Depletion Potential (ODP), Global Warming Potential (GWP),
and Total Equivalent Warming Impact (TEWI). All of which is described by some
numerical values based on some reference states. The computations of these indexes are
complex and involve a large number of analytical, experimental and empirical data
inputs. The practice will continue as more developed and sophisticated models are
introduced. The numbers associated with each approach are continuously being revised
with the availability of more data.
1.1.1
Ozone depleting effect
The presence of the ozone layer prevents the UV radiation from reaching the
earth. The ozone depleting effect involves the reduction and/or removal of this thin
layer, allowing the harmful UV radiation to reach the crops and the phyto-plankton of
the oceans. Life on earth depends either directly on indirectly on these minute organisms
with some of the consequences being an increase in the incidents of skin cancer,
cataracts and impairment of the body's immune system. [17]
Both CFCs and halons (related chemicals which contain bromine) are chemically
stable and can persist for many years in the atmosphere. Their eventual breakdown in the
stratosphere releases halogens, with the CFCs releasing chlorine and the halons releasing
bromine. These halogens break down the ozone layer without being destroyed. Thus,
one halogen atom can breakdown thousands of molecules of ozone before it is finally
removed from the atmosphere. The extent of the destruction very much depends on the
type (Cl2 or/and Br2) and number of halogens being released, and its residence time in
the atmosphere. A relative index, ODP, is assigned to a substance indicating the extent
3
to which it may cause ozone depletion, with CFC 11 used as the reference point having a
value of 1. A substance with a given weight, having an ODP of 0.5 would mean that it
would deplete half the ozone that the same weight of CFC 11 would.
1.1.2
Global Warming Effect
The global warming effect is the increased in the earth’s temperature which is
brought about by the absorption of long wave radiation by various gases present in the
troposphere. The layer extends to about 15 km over the earth’s surface with the gases
behaving as an insulator. Under normal circumstances, the warming up effect raised the
earth’s temperature from as low as –18oC to acceptable living conditions. Natural
concentrations of C02 and H20 actually keep up the balance. However, a fraction change
in this effect can significantly influence the wind flow pattern and subsequently the
weather conditions. Continuous heating up of the earth’s surface may have caused the
increase in sea level and the melting of the ice caps. The extent of effects is described
with the index GWP [17].
A refrigeration system releasing molecules of CFSs may have adverse long term
effects on the environment depending on the length of time it stays in the atmosphere.
The index GWP for different gases is based on C02 with R11 sometimes used as the
reference gas. Since each has a GWP value of unity, it is important to mention the
reference gas when using GWPs.
1.1.3
Total equivalent warming index
Another approach to describing the effects of CFCs is the concept of Total
Equivalent Warming Index (TEWI). This last method involves the energy consumption
of the equipment during its operation, which may also contribute to global warming. The
4
amount and type of blowing agent used in the insulation, the energy consumption over
the system expected lifetime, and the contributions from the refrigerant itself are factors
that must be taken into account. [17].
1.2
Background
Molina and Rowlands (1974) maintained that CFCs UV radiation in the
stratosphere principally destroyed the ozone layer. The chlorine released in the high
stratosphere encouraged the decomposition of ozone to oxygen allowing UV radiation to
penetrate to lower altitudes. A constant CFC emission of 700,000 tonnes per year can
deplete up to 3% of the ozone layer after a hundred years (Ho Man, 1987).
Starting from the mid seventies through the eighties, scientists have discovered
an alarming decrease in ozone over Antarctica and Arctic during the winter months. The
so-called ozone holes over both poles, which grew larger each year, were linked to
CFCs released into the atmosphere. The CFCs slowly diffused into the stratosphere
(upper atmosphere) and get partially broken down by sunlight releasing free radicals in
the process. Studies have proven that these free radicals react with ozone.
The danger posed by CFCs had many countries, among them the United States,
Sweden, Finland, Norway, and Canada, banning the use of CFC-11 in spray cans in the
late 1970s. Then in September 1987, 24 developed nations signed the Montreal Protocol
to cut production of five CFCs with additional agreements signed between 1990 and
2000. CFCs have been replaced by less stable CFC compounds and by non-CFC
chemicals, which break down before they reach the stratosphere.
Puong, et al (1987) found that among the R21-DMETEG, R21-DMF, R22DMETEG, and R22-DMF of fluorocarbon refrigerant, R21-DMETEG stands out as the
most suitable solution for low temperature vapour absorption heat pump (VAHP)
applications. Correlations are given for a quick estimation of COP and limiting generator
5
temperature. The performance characteristics compared are total heat output per unit
solution flow rate, heating coefficient of performance (COPh), second low efficiency and
circulation ratio.
Vincent L. DiFiliippo (1989) illustrated HFC- 134a as a replacement for CFC-12
with a technical overview of converting reciprocating air conditioning and refrigeration
systems to HFC-134a. Their study summarized HFC-134a land based and shipboard test
results, as well as expanded on the technical developments experienced during the
implementation process.
Wen-Lu Weng and Bin-Chang Huang (1995) used the Iwai-Margerum-Lu
equation of state in their study of the thermodynamics performances of a variety of fluid
circulating in an ideal heat pump cycle. Their evaluations were implemented at three
operating conditions. Their result showed that the normal boiling point and the critical
pressure of compounds are the key properties for selecting the thermodynamically
proper working fluids. Several potential non-CFC compounds were suggested for the
heat pumps with respect to each application depending on the compressor type.
I. L. Maclaine-cross and E. Leonardi (1995) in their paper mentioned that
initially R290 could replace R22 while LPG mixtures can replace R12 and R134a. The
halogen free refrigerant (R600a) gives the highest value of COP compared with other
refrigerants such as RC270, R12 and R134a. The market for R600a grew as new
equipment exploits the advantages of its lower vapour pressure. The refrigerant has half
the leakage, pressure loss, condenser pressure, and twice the heat transfer properties of
R12 and R134a. Energy consumption savings is also achieved with R600a refrigeration
systems.
S.M.Sami and P.J.Tulej,(1995) studied the comparative performance of ternary
blends proposed as substitution for CFC-12. An experiment to evaluate the blend
performance was set up, which includes a domestic refrigerator. The ternary blend
6
NARM-12 was found to consume 35% less energy than CFC-12, and exhibits shorter
cycles at comparable pressure ratios than CFC-12.
A. Stegou, (1996) in his study of the thermodynamic properties formulations and
heat transfer aspects for replacement refrigerant - R-123 and R-134a - stressed about
analytical relations for the thermodynamic properties, enthalpy, entropy, and heat
capacities at constant pressure and temperature of the replacement refrigerants R-123
and R-134a. The isentropic change in the particular fluids was also studied and a set of
graphs were plotted to illustrate the dependence of these exponents on the pressure and
temperature. The results are useful in efforts to improve the basic design as new
refrigerants are being considered to replace the CFCs refrigerant.
S.B. Riffat, et al (1996) presented a review of the application of the main natural
refrigerants for refrigeration and air conditioning systems as an alternative to synthetic
new refrigerants (HFCs). The natural working fluids that have been studied are Air,
H2O, CO2, NH4, Hydrocarbons and etc. Their result showed the hydrocarbons give the
better COP compared of CFCs refrigerant.
D. T. Ray, et al (1997) developed correlations for CFC-114 and HFC-236ea. The
model was tested for a range of inlet condenser water temperatures and evaporator loads.
The results are presented and compared with data provided by the Naval Surface
Warfare Center (NSWC) in Annapolis, MD. Several recommendations to further
improve the performance of HFC-236ea in Navy chillers were given. They include
adjusting the load of the evaporator to achieve positive gauge pressure, use of a purge
device, use of a variable speed compressor, further testing with azeotropic mixtures, and
use of high performance tubes in the heat exchangers. The results yield additional
insight as to the possible suitability of HFC-236ea as a drop-in substitute for CFC-114.
According to C. Aprea, et al (2002) found that the best results of the exergy
analysis have been obtained using R22 followed by non-azeotropic substances. R22
performance was found to be consistently better than that of its candidate substitute, the
7
non-azeotropic mixture R407C. The difference stems from the different irreversibilities
of the plant components arising when using R22 and R407C, respectively. Specific
attention is devoted to compressor irreversibilities. Performance indices related to the
semi-hermetic compressor are evaluated when using either refrigerant.
It is widely accepted that alternative refrigerants must replace the CFCs with
equal if not better performance and efficiency. This study will determine the non-CFC
refrigerants performance in terms of 1st and 2nd law of thermodynamics depending on the
refrigerant types. The useful properties of some HCFCs, HFCs and industrial organic
refrigerants in the industry will be compiled in an accessible way and their performance
in some systems simulated. A software that can determine the performance of the
refrigerants and their potential replacement counterparts for a quick evaluation. The
package will help industries associated with the use of refrigerants in general to have a
better understanding of the system with the replacements. Local industries in particular
will be encouraged in the transition to environmentally friendly refrigerant by using
locally made software.
CHAPTER II
THEORY AND FORMULATION
2.0
Theory and formulation
First law of thermodynamics stated that the energy associated with the matter
entering the system plus the net heat added to the system is equal to the sum of the
energy associated with matter leaving the system, the net work done by the system and
the change in energy of the system [15].
The second law of thermodynamics provides a method of determining whether
a process can take place between one specified state to another. It also explains why
some processes can spontaneously occur while others cannot. The second law does not
lead to an equation, but an inequality [16]. Since the performance based on the first law
makes no reference to the best possible performance, the second-law efficiency or
coefficient of performance (COP) is more frequently used. The latter gives a realistic
measure of the engineering devices in terms of the useful work potential of a system at a
specified state: exergy. The conditions of the environment (dead state) and the properties
of the system being studied determine the exergy of that system. The second law
efficiency or COP is defined as the ratio of the exergy (also called availability
elsewhere) recovered to the exergy supplied. A worst case would be when there is a
complete destruction of exergy, and the best being no destruction at all.
2.1
Refrigeration cycle
Figure 2.1 is a schematic of a 2T-refrigeration cycle, heat is received, QL , from a
reservoir at TL and rejected, QH , to a reservoir at TH . The temperatures of regions
within the refrigerator where heat is received and rejected are noted as TB and T A ,
respectively, on the diagram. [15];
The COP is given by
COPref =

Wnet
(2.1)
Appling the first law of thermodynamic to the cycle gives
∫ dQ + ∫ dW = 0
(2.2)
or
QL − QH = Wnet
(2.3)
Therefore, the COP for a refrigerator is
COPref =

Where, Wnet is the net work produced.
2.2
Ideal vapor –compression refrigerant cycle
The Carnot heat engine cycle is a totally reversible cycle. Although ideal and
nonexistent, the cycle, as a heat engine or refrigeration system, is used as a guide and
comparison purposes to engineers. The latter is called the ideal vapor compression
refrigerant cycle and will be used to determine the performance of each refrigerant and
its potential replacement counterparts in this study.

(2.11)
Neglecting kinetic and potential energy, equation (2.10) is substituted into (2.9) to give
ψ i = (hi − ho ) − To (si − s o )
(2.12)
Where
ho = Enthalpy at the room temperature, To of atmospheric pressure
so = Entropy at the room temperature, To of atmospheric pressure
Equations (2.9) through (2.12) are substituted into (2.6) giving the compressor
irreversibility, ic
ic = [(h1 − ho ) − To (s1 − s o )] − [(h2 − ho ) − To (s 2 − s o )] + (h2 a − h1 )
(2.13)
Similarly, condenser irreversibility, icond, is given by

T
icond = ψ 2 − ψ 3 + ∑ q cond 1 − o
 T2 a



(2.14)
With the heat received from condenser qcond given by
q cond = h3 − h2 a
(2.15)
Substitution of equations (2.12) into (2.14) into gives

T
icond = [(h2 a − ho ) − To (s 2 − s o )] − [(h3 − ho ) − To (s3 − s o )] + (h3 − h2 a )1 − o
 T2 a
For throttling valve irreversibility, ivalve, it is given by



(2.16)
ivalve = ψ 3 − ψ 4
(2.17)
Using (2.12), the throttling valve irreversibility, ivalve becomes
ivalve = [(h3 − ho ) − To (s 3 − s o )] − [(h4 − ho ) − To (s 4 − s o )]
(2.18)
And for the evaporator irreversibility, ievap ,
 T
ievap = ψ 4 − ψ 1 + ∑ q evap 1 − o
 T4



(2.19)
Where heat received from condenser qevap is given by
q evap = h4 − h1
(2.20)
Substitution of equations (2.12) into (2.19) gives
 T
ievap = [(h4 − ho ) − To (s 4 − s o )] − [(h1 − ho ) − To (s1 − s o )] + (h4 − h1 )1 − o
 T4



(2.21)
For the equation of the total irreversibility, itotal, of a vapor compression refrigerant,
equations (2.13), (2.15), (2.18), and (2.21) are substituted into equation (2.7). The total
irreversibility then becomes
itotal = [[(h1 − ho ) − To (s1 − s o )] − [(h2 a − ho ) − To (s 2 − s o )] + (h2 a − h1 )] +



(2.22)

The second law effectiveness of a refrigerator can also be defined as

(2.25)
Where
Φ Q ,evap = ∆ψ evap
(2.26)
with the exergy of the evaporator given by
∆ψ evap = ψ 1 − ψ 4
(2.27)
Φ Q ,evap = ψ 1 − ψ 4
(2.28)

Substituting equation (2.10) and (2.27) into (2.25),
ψ −ψ 4 

η II = − 1

(2.29)
And substituting equation (2.12) into (2.29) gives the second law efficiency

Programming

Visual Basic 6.0
The program used to do the analysis is Visual Basic. Figure 2.6 shows the
flow chart of the programming. Visual Basic is based on a programming language
written for beginners called BASIC. With Microsoft Visual Basic, new programmers
could become proficient right away. Other programming languages of the day, such as

Basic has a very good data environment designer, which visually creates reusable set of
command objects with drag-and-drop functionality. It has the functionality to bind to
multiple data sources for data aggregation and manipulation. Using the new Data
Environment designer, developers can quickly drag-and-drop custom data-bound
controls to create forms or reports with the new Data Report designer. Creation of
custom data hierarchies is as easy as filling out a dialog box and dragging the command
to the form. Other than these, Visual Basic has several other key advantages also such
as it is excellent for creating user friendly interfaces and enables rapid development for
small business applications. For designing Internet applications developer can easily use
predefined objects available with the Professional and Enterprise editions of Visual
Basic and it is a popular business programming language.
CHAPTER III
ALTERNATIVE REFRIGERANT
3.0
Alternative Refrigerant
A series of counteractive measures have been taken by the refrigeration
industries to address the problems associated with ozone depletion and the green house
effects. The area of commercial refrigeration and air conditioning plants have been
studied, in particular the role played by the hazardous refrigerants and their potential
replacements [14].
3.1
Substitution of the alternative refrigerant
Alternative refrigerants being considered as replacements to the CFC refrigerants
must have similar thermodynamic properties and behavior in terms of trends and
patterns. They include: 1.
Discharge gas temperature and evaporation temperature
2.
Pressure at every temperature
21
3.2
Characteristics of working fluids for refrigeration applications
There are numerous new fluids and mixtures that are considered to be
environmentally safe for substitutes. However, it is important to study thoroughly their
properties that make the fluids suitable working fluids. Comparisons based on
thermodynamic, thermo physical, environmental and safety related properties are among
the pertinent studies required. This chapter discussed the refrigerants groups and certain
characteristics that are relevant to their functions in the refrigeration industries.
3.2.1
Fully halogenated Chlorofluorocarbon (CFC)
These are various classes of refrigerants that possess high Ozone Depleting
Potential (ODP) and come under strict control of the Montreal Protocol and subsequent
revisions. The refrigerants covered under this classification are R11, R12, R13, R112,
R113, R114 and R115.
3.2.2
Partially halogenated Chlorofluorocarbons (HCFC)
Fully halogenated CFCs contain only halogen atoms including CI in addition to
carbon atoms. In partially halogenated compounds, only some hydrogen atoms are
replaced by halogen atoms. The remaining hydrogen atoms facilitate partial breakdown
of the compounds in the troposphere and are regarded to be less harmful to the
stratospheric ozone layer. Partially halogenated CFCs are referred to as HCFCs. The
letter H meant that the hydrogen atoms are still available in the molecule. HCFC was
introduced mainly to distinguish them from the fully halogenated CFCs so that they can
be classified separately. They cause less or negligible damage to the ozone layer. [17]
22
However, at the Copenhagen Meeting in 1992, this view has been revised and
these HCFC's were then included in the list of controlled substances. The impact upon
the refrigeration and air-conditioning industry has been great because the R22, which is
widely used, would have to be phased out. For Germany, as R22 was already phased out
for new plants by the end of 1996 (only four years after the Copenhagen meeting).
3.2.3
Halons
Halons are a class of fully halogenated hydrocarbons which contain Bromine
beside Chlorine and Fluorine. Bromine has a higher ozone depleting capability than
Chlorine, where halons in general have very high ODPs and GWPs. However, they are
still widely used in fire extinguishers and to some extent as refrigerants. Halons suppress
the fire chemically by removing the reactive species from the combustion zone whereas
water and carbon dioxide extinguishes fire physically.
3.2.4
Hydrofluorocarbons (HFC)
R23, R32, R125, R134a, R143a and R152a are hydrofluorocarbons.
Hydrocarbons contain fluorine but no chlorine or bromine in the molecule. The absence
of chlorine and bromine made the hydrocarbons safe from the ozone depletion behavior.
Unfortunately, the hydrofluorocarbons are chemically stable and can accumulate after
release. The accumulation of hydrocarbons may cause a significant greenhouse effect.
3.2.5
Fluoroiodocarbons (FIC)
Fluoroiodocarbons (FICs) are a recent group of chemicals with fluorine, iodine
and carbon. Some like Trifluoromethyl Iodide (CF31), perfluoroethyl iodide (C2F5'),
23
and perfluoropropyl Iodide (CF7l) are now being considered as potential replacements
for CFCs and halons. They have zero ODP and negligible GWP due to their very short
life periods. [17]
FICs can also be used in blends, where a blend of CF31 and HFC 152a (51/49
mole percent) can be used in a refrigerator without oil change for more than 1,500 hours
without any negative effects. The energy efficiency and capacity of the blends were
measured to be equal to or slightly better than CFC 12. [17]
3.2.6
Hydrocarbons
Non-halogenated organic compounds such as alkanes, ketones, alcohols and
ethers also have the possibility of being considered as replacement refrigerants. They are
, however, highly flammable and thus are not being seriously considered except in
certain industrial applications. They are used in pure or mixture forms as refrigerants in
petrochemical plants and in gas liquefaction plants. In LNG plants, mixtures of methane
to n-pentane are commonly used. Adequate care taken, the flammability of hydrocarbons
does not pose a big problem. [17]
3.2.7 HFCs and HFC blends
HFCs and HFC blends can be used as alternatives for both CFCs and HCFCs
because they have zero ODPs. However, the use of HFCs and most HFC blends are
more expensive in retrofit exercises because they require the use of synthetic lubricating
oils instead of the more conventional mineral oils that CFCs and HCFCs use. It is still a
practical proposition in many situations.
Other than having no effect on the ozone layer, HFCs also have lower GWP than
CFCs. The most favorable properties of HFCs would be its zero flammability and zero
24
toxicity which makes HFCs a popular alternative in both existing and new systems[17].
Figure 3.1 shows the application range of HFC refrigerant and blends.
Figure 3.1 Application range of HFCs and HFC blends [14].
3.2.8 HCFCs and HCFC blends
HCFCs and HCFC blends can also provide a practical alternative to CFCs.
However, their usage can only be transitional as HCFCs since they are ozone depleting
as well and will be phased out in the near future (1st January 2010 for use of virgin
HCFCs for maintenance). Most HCFC blends are useful indirect expansion (DX) CFC
systems and have been specially developed to provide a low cost retrofit. Figure 3.2
shows the application range of HCFCs and HCFC blends.[14]
25
Figure 3.2 Application range of HCFCs and HCFC blends [14].
3.2.9
Ammonia and Hydrocarbons (HCs)
HCs, also known as "natural refrigerants" have excellent thermodynamic
properties. However, they require specialized equipment specifically meant for a
particular refrigerant. For example, ammonia can only be used in new equipment
specifically designed for ammonia. Although they have excellent thermodynamic
properties, they are generally highly toxic and slightly flammable. They can only be
used in existing systems if great care is taken to address safety issues. Ammonia is
already a very popular refrigerant in the industrial sector but it is restricted to systems in
the remote area, which are far from public access. Materials incompatibility also makes
ammonia generally unsuitable for small vapor compression systems [14].

21
3.2.10 Other Substitutes
There are other substitutes that are being considered, or coming back after having
been displaced by CFCs for half a century, among them are ammonia (R717), Water
(R718), air (R729), and Carbon Dioxide (R744).

3.3
Blends and mixtures
Another alternative to the problem of limited number of working fluids with
suitable properties may also be solved by using refrigerant mixtures. A mixture of
refrigerants allows adjustment or tuning to the most desirable properties of a mixture by
varying the molar fraction of the components. There are three categories of mixtures,
which can be used as working fluids. They are:
•
Azeotropes
•
Near-azeotropes
•
Zeotropes.
3.3.1
Azeotropes
Azeotropes (no change in boiling) are usually binary mixtures that have long been
used in the refrigeration industry. During phase change, the concentration of each
constituent in liquid and vapor phases is the same as in a single phase. This means that
azeotropes behave like a single component fluid during its phase change at a given
concentration. At constant Pressure (which is connected to a maximum in pressure at
constant temperature), most commonly used azeotropes exhibit a minimum bubble point.
R500, R502 and R503 have been in use in many commercial applications where
R500 is the azeotrope of R12 and R I 52a. R500 has the same capacity when used with a
50 Hz current as R12 with a 60 Hz current. The refrigeration capacity of R500 is
approximately 20% greater than. The applications of R500 may have resulted from the
industry's need for filling the capacity midway between R12 and R22. [20]
R503 has a boiling point of 85 degree Celsius and it is the azeotrope of R23 and
R13. It provides a non-flammable alternative and is approximately 6oC below the boiling
30
points of the two components, and with the same boiling point as ethane. Because of that,
R503 is suitable in low temperature refrigeration systems. [20]
R502 is the azeotrope of R22 and R115 and is used as a refrigerant for freezers
such as supermarket frozen food display cases. It has a significantly lower compressor
discharge temperatures than R22 and R12. [20].
3.3.2
Near-azeotropes
Near-azeotropes are mixtures with close normal boiling points. They have small
differences in liquid to vapor compositions in equilibrium conditions. Near-azeotropes
have a great potential for development and as drop-in alternatives to CFCs.
The discovery of near-azeotropes extends and widens the range of refrigerant
alternatives beyond single compounds and azeotropes. However, the use of nearazeotropes is also restricted to equipments that are originally designed for single
component refrigerants. A near-azeotrope modification of R502 was developed as a
means to improve the oil solubility. The heat transfer coefficient was found to increase
when propane (amount limited to 6.8% to maintain a non-flammable composition) was
added to R502 to increase solubility in naphthenic: oil [20].
3.3.3
Zeotropes
Zeotropes are known as Non-azeotropicrefrigerant blends (NARBs), or simply
non-azeotropes or blends. The substances exhibit significant changes in temperatures and
compositions of individual phases during evaporation and condensation. Zeotropes can
potentially improve the energy efficiency and capacity, and being seriously considered as
31
alternative refrigerants. Again, the drawback of zeotropes is that it can only be used in
new systems designs because they require hardware design changes.
CHAPTER IV
RESULTS AND DISCUSSION
4.0
Comparison of different working fluids
In this chapter, comparison between different working fluids listed is made based
on thermodynamic and thermophysical properties, and also on the vapor compression
cycle. The comparison is made for a different pressure leaving the compressor. Every
refrigerant selected followed the first law, while the potential for producing useful work
was reduced (second law). A relationship between the irreversibility, COP and the
second law efficiency can be seen from the graphs obtained. Meanwhile the compression
ratio with a constant condensing pressure is not proportional to the COP and the second
law efficiency but proportional to the irreversibility.
The results were obtained by assuming that the isentropic efficiency is 70% with
varying exit pressure and inlet pressure held constant. The percentage was chosen
because the entropy efficiency for practical devices is usually in the range of 65% to
80%. The information is computed from technical information of DuPont
Fluorochemicals (refer appendix A). Table 4.1 shows the banned refrigerants and the
substitutes that have been compared.

Coefficient of Performance (COP)
R12, R22 and R502 are HCFC and HFC banned refrigerants and other new
refrigerants have substituted them.
The substitutes normally have similar
thermodynamic properties. Substitutes for R12 are R134a, R401a and many more. The
analyses were completed for a condensing pressure of 200 kPa and the evaporating
pressure of 700 kPa to 1300 kPa. R12 refrigerant, which is also called
Difluorodichloromethane, is related to the CFC group. It is characterized by a high ODP
(ODP = 1) and big GWP (GWP = 8500). It is a clear gas with a specific smell, and 4.18
times as heavy as the air. Studies have shown that R134a has a higher COP over R12
and R401a [17].
The COP of R134a shows a 12% increase over that of R12 while COP of R401a
is not much different from the latter (Figure 4.1). The performance of the substitute
R401a is only slightly higher after the condensing pressure goes beyond 1000 kPa. As
for how one could improve the R401a refrigeration cycle, changing the lowest
temperature from –40 degrees Celsius to –30 degrees Celsius would indeed help. This
would make the heat taken out of the low temperature region larger and the work by the
compressors smaller. Thus we have a higher COP, which means a more efficient system,
and smaller workload for the compressors.

For HCFC, performance of R22 is compared with one of the substitutes, R407c
(HFC chlorine free). In this analysis the pressure that enters the compressor is held at
400 kPa and the exit pressure is between 1200 kPa to 1800 kPa. The results show that
R22 has a higher value of COP. The curves show that at the condensing pressure of 1200
kPa the COP of R22 and R407c is 4.23 and 3.85 respectively (Figure 4.2). The COP for
the substitute never went above 0.39.

R502 has been substituted by R402a and R402b. R502 refrigerant is an
Azeotrope blend of R22 and R115 refrigerants. R22 mass proportion constitutes 48.8%,
and R115, 51.2%. R502 is related to the CFC group, has the following ecological
characteristics: ODP = 0.33; GWP = 4300 [17]. The results show that the COP of R402a
and R402b is similar. Figure 4.3 is a plot of COP against pressure leaving the
compressor where the pressure entering the compressor is held constant at 500 kPa.
R402a has a highest COP at the condensing pressure of 1200 kPa.

4.1.1
Compression Ratio (Constant Pressure Entering the Compressor)
Compression ratio is a ratio of the pressure leaving the compressor to the
pressure entering the compressor. For R12, R22 and R502 and the substitutes, they have
been analyzed by different compression ratio with the pressure entering the compressor
held constant. The COP of every refrigerant is not proportional to the compression ratio.
The plot will show the curve is similar to the Figure 4.1 through 4.3.
36
4.2
Second law efficiency
The second law efficiency includes the exergy change associated with enthalpy
at the evaporator and the compressor work [15]. The analysis was done by assuming the
room temperature (To) to be 25ºC and the atmospheric pressure (Po) 101.325 kPa. The
second law efficiency decreases due to the increasing condensing pressure with the
constant evaporating pressure. Figure 4.4 shows the plot of second law efficiency
against pressure for R12 and the substitutes. The results show that R401a has a better
efficiency than R12 and R134a. This is because the enthalpy and the entropy at the
atmospheric pressure, Po influenced the changing of the exergy of enthalpy. In this
analysis, kinetic energy and potential energy changes have been neglected.
R401a has a lowest value of the enthalpy and entropy at the atmospheric
pressure.

properties show that R407c have a higher value of enthalpy and entropy at 25oC and the
atmospheric pressure. Since R407c has a higher compressor work compared to R22, the
superheated condition of R407c results in a higher enthalpy.

4.3
Total irreversibility
If the process considered is reversible, the work is the maximal possible between
two thermodynamic states. Calculating W by the variation of exergy gives a more
realistic result than calculating it by the energy balance. Since real processes are
irreversible, exergy balances are more useful and an improvement to the conventional
energy method.
Figure 4.7 shows the total irreversibility of R12 and the substitutes. R401a shows
a large total irreversibility compared to R12 and R134a. In this case, the compressor is a
big contributor to the total irreversibility. That is why R401a can perform better in the
aspect of second law efficiency even with a large value of total irreversibility. R12 have
a lower value of total losses and cannot perform as well as R134a and R401a in terms of
COP and second law efficiency because the exergy value at the evaporator is the lowest
and the high compressor work.

Relationship or Pressure and Temperature
Relationship between pressure and temperature is one of the characteristics that
must be taken into consideration for substitute refrigerants. A plot of the saturated vapor
pressure against temperature for R134a, R12 and R401a is shown in Figure 4.10. It is
clearly seen that R134a, R12 and R401a have nearly the same vapor pressure. At the
temperature 20 to 80ºC, R12 has the lowest vapor pressure relative to R134a and R401a
mixture. R401a refrigerant is a zeotrope average pressure blend. The difference in the
vapor pressure among the refrigerants is less than 250 kPa.

R407C refrigerant is a zeotrope blend of R32/R125/R134a (mass proportions of
the components, correspondingly, 23/25/52%). Initially, the refrigerant of the following
composition had been created: 30/10/60 %. [19] before the latter composition of R407c
was conceived. R407C refrigerant according to its energy effectiveness is close to R22
and is considered as optimal alternative to R22. Figure 4.11 shows the plot of Pressure
41
against temperature for R22 and R407c. The graphs for R22 and R402, each for
saturated liquid and saturated vapor, show almost the same shape.

The theoretical comparisons of the performance of the new and old working
fluids in refrigerated systems can help in the planning and implementation of new and
retrofit systems. Beside the environmental friendly characteristics, for a real world
application, the type of compressor and the lubricant of the system must also be
considered.
4.5
Discharge Temperature
Discharge temperature is the exit temperature after compression. The condition
at this point must be superheated. A lower discharge temperature produced less strain on
the compressor and hence a longer compressor life [17]. In addition, the oil is less likely
to break down. Figure 4.12 shows the comparison of the plot of R12 and the substitutes.
The results show that R401a has a highest discharge temperature and R134a shows the
lowest. The increase in discharge temperature is proportional to the increasing
condensing pressure.

R22 has a significantly higher discharge temperature than R407c blends as
shown in Figure 4.13. The increasing discharge temperature is proportional to the
increase in condensing pressure. At the condensing pressure of 1200 kPa, the discharge
temperature of R22 and R407c is 62.44ºC and 56.37ºC respectively. The difference is
only 6ºC at first but exceeds to 10ºC at 1800 kPa.

CHAPTER V
CONCLUSION
A software package has been produced that can simulate the performance of
refrigerants. COP, second law efficiency, total irreversibility, and discharge temperature
could be performed on refrigerants and their potential replacement counterparts.
Simulation on the performance of refrigerants R12 (CFC), R502 (CFC), and R22 (HFC)
were completed and compared with the more environmentally friendly refrigerants,
R134a (HFC), R401a (HFCFC/HFC blends), R402a and R402b (both HFCFC/HFC),
and R407c (HFCFC/HFC). R134a was found to be a potentially good replacement for
R12 while R402a for R502. As for the replacement of R22, the only potential
replacement, R407c was found to behave similarly to R22.
The package could be used by industrialists who are considering replacing their
refrigerants with more environmentally friendly ones. Future improvements to the
package with additional data on refrigerants may encourage more industries to consider
new or retrofit systems that do not deplete the ozone layer or/and alleviate the green
house effects.

Thermodynamic Properties of SUVA HP81 Refrigerant
SI Units
New tables of the thermodynamic properties of SUVA®
HP81 refrigerant [ASHRAE designation: R-402B (38/2/
60)], a near azeotropic blend of HFC-125/HC-290/HCFC22, have been developed and are presented here. These
tables are based on extensive experimental measurements.
Equations have been developed, based on the PengRobinson-Stryjek-Vera (PRSV) equation of state, which
represent the data with accuracy and consistency throughout the entire range of temperature, pressure, and density
presented in these tables.
Reference point for enthalpy and entropy:
hf = 200 kJ/kg at 0°C
sf = 1 kJ/kg • K at 0°C
Equations
The Peng-Robinson-Stryjek-Vera (PRSV) equation of state
was used to calculate the tables of thermodynamic properties. It was chosen as the preferred equation of state
because it provided an accurate fit of the thermodynamic
data over the entire range of temperatures and pressures
presented in these tables.

Properties calculated in SI units from the equations and
constants listed above can be converted to I/P units
using the conversion factors shown below. Please note
that in converting enthalpy and entropy from SI to I/P
units, a change in reference states must be included
(from H = 200 and S = 1 at 0°C for SI units to H = 0
and S = 0 at –40°F for I/P units). In the conversion
equations below, H (ref) and S (ref) are the saturated
liquid enthalpy and entropy at –40°C. For SUVA®

Thermodynamic Properties of SUVA HP81 Refrigerant
SI Units
New tables of the thermodynamic properties of SUVA®
HP81 refrigerant [ASHRAE designation: R-402B (38/2/
60)], a near azeotropic blend of HFC-125/HC-290/HCFC22, have been developed and are presented here. These
tables are based on extensive experimental measurements.
Equations have been developed, based on the PengRobinson-Stryjek-Vera (PRSV) equation of state, which
represent the data with accuracy and consistency throughout the entire range of temperature, pressure, and density
presented in these tables.
Reference point for enthalpy and entropy:
hf = 200 kJ/kg at 0°C
sf = 1 kJ/kg • K at 0°C
Equations
The Peng-Robinson-Stryjek-Vera (PRSV) equation of state
was used to calculate the tables of thermodynamic properties. It was chosen as the preferred equation of state
because it provided an accurate fit of the thermodynamic
data over the entire range of temperatures and pressures
presented in these tables.

The constants for the PRSV equation of state were calculated in SI units. For conversion of thermodynamic
properties to Engineering (I/P) units, conversion factors
are provided for each property derived from the PRSV
equation of state.

that in converting enthalpy and entropy from SI to I/P
units, a change in reference states must be included
(from H = 200 and S = 1 at 0°C for SI units to H = 0
and S = 0 at –40°F for I/P units). In the conversion
equations below, H (ref) and S (ref) are the saturated
liquid enthalpy and entropy at –40°C. For SUVA®
HP81: H (ref) = 151.4 kJ/kg and S (ref) = 0.8092
kJ/kg • K.

df and Dc are in kg/m3 in SI units and lb/ft3 in I/P
units; T and Tc are in K in SI units and °R in I/P
units; a0, a1, a2, a3, a4, and t0 are constants:
3. Density of the Saturated Liquid
df/Dc = a0 + a1 z + a2 z2 + a3 z3 + a4 z4
where z = (1 – T/Tc)1/3 – t0
Because both density and temperature appear in the
reduced form in the equation, the same constants can be
used for either SI or I/P units.
