So…
How do the
TM
3TM
ESM & ECO
achieve savings?
Background
• Majority of controls concentrate on
conditioned space temp, chilled
water temp or suction pressure
• Compressors are switched ON in
response for cooling and will
operate until that demand is
satisfied
• To avoid (short cycling), which will
cause damage to compressors, the
control bands are usually set with a
min. differential of approx. 4 PSI or
2° C.
•
Background
(cont’d)
Compressor capacity to remove heat
is directly proportional to the operating
temperature
• The higher the controlled temperature,
the higher the suction pressure
(evaporator temperature), the faster
the rate of heat removal
• When compressor first starts at high
limit point it will operate at maximum
efficiency with a high suction pressure
• As the conditioned space temp. is
reduced, the suction pressure drops
and compressor capacity is reduced
• Each degree of temperature reduction
takes a longer period of time and uses
more electricity
Background (cont’d)
• The table to the right, shows a
typical chiller compressor capacity
chart for a nominal 40 kWh heat
load, showing the time & energy
taken per degree of temp.
reduction
• Reducing from 6° to 5°C takes
14.4 minutes and 3.57 kWh
• The last degree of pull down uses
almost twice the energy and time
The example above, uses a +(-) 2.5° C suction
temperature differential
Background (cont’d)
• The chart to the right illustrates
the percentage of energy used
per degree.
• The last degree of pull down
used 28% of the total energy for
the cycle
Unfortunately, this increases the mid point
temperature from 7.5°C to 8°C.
COMPRESSOR OPTIMIZATION
• Designed to work with the existing refrigeration equipment, along with
the current control methodology, to reduce energy consumption
• When a call for cooling comes from the existing controller, the
advanced control module takes over to determine when and for how
long each compressor or unloader will run
• This advanced control technology enable the compressor to maximize
the rate of heat removal by optimizing the natural physical properties
of the compressor operating cycle
Compressor Optimization
• This “Optimization” is done
with no appreciable
difference to the
temperature being
controlled
Compressor Optimization
• By creating more time where
the compressors operate in
the higher suction pressure
area, the ESM™ have the
compressors run more often
when they are more efficient.
• By running less, the
compressors energy usage
is reduced.
Smartcool Technology
Result:
• The ESM™ and ECO3™ increase the efficiency of the compressors by
causing the refrigeration or A/C system to operate at a higher suction
pressure
• The ESM™ and ECO3™ reduce the total run time of the compressors
resulting in a reduction of electricity use
• Because the compressors are operating more efficiently pre-set
controlled space temperature performance is maintained with fewer
operating hours and less electricity use
THIRD PARTY VALIDATION
Smartcool has undergone significant independent third party testing, proving its energy
saving capabilities. Of particular note are the following tests:
Florida Power & Light:
The University of Miami conducted extensive testing on behalf of FP&L of the ESM™ over a
twelve month period in 2006. The testing showed that the ESM™ reduced kWh usage of the
entire air conditioning system by 8.9% – which provides a savings of 13.38% of the kWh
usage by the compressors, an annual reduction of 43,660 kWh and a reduction in
greenhouse gas emissions of 58,911 lbs.
Oak Ridge National Laboratory:
ORNL conducted a two phase test of the ESM™ in 2004-2005. The first phase of the test
involved the analysis of data collected from an installation on a refrigeration rack in a grocery
store. The second phase evaluated the ability of the ESM™ to reduce the electrical
consumption of a four compressor roof top unit in a controlled laboratory environment. Test
results showed an 11.87% reduction in kWh usage by the compressors in the system and a
2.2% demand (KW) reduction.
