3 Types of Dehumidifiers
 Standard Refrigerant
– Temperature range 68OF - 90OF
– How dry can it get the air?
 LGR Refrigerant
– Temperature Range 33OF - 90OF+
– How dry can it get the air?
 Desiccant
What does a refrigerant
dehumidifier do? How does it do it?
Let’s start with an air conditioner:
This is how the evaporation cycle in an air
conditioner or dehumidifier works:
1.The compressor compresses
cool refrigerant gas, causing it
to become hot, high-pressure
gas (red in the diagram
above).
This is how the evaporation cycle in an air
conditioner or dehumidifier works:
2.This gas runs in narrow tubes
through coils dissipating or
giving off its heat. When cooled
it condenses to a liquid. (Going from
bottom left to top left in diagram)
This is how the evaporation cycle in an air
conditioner or dehumidifier works:
3.The liquid refrigerant passes
through an expansion valve. In
the process it evaporates to
become cold, low-pressure gas
(light blue).
This is how the evaporation cycle in an air
conditioner or dehumidifier works:
4.This cold gas runs through a
set of coils (light blue) that are
cooled by the gas. Air passing
over the cold coils is also cooled.

LGR Dehumidifiers
What is LGR?
Low Grain Refrigerant dehumidifiers
They pre-cool the incoming air stream.
LGR Dehumidification Equipment
LGR Dehumidification
Equipment
There are two types of
LGR dehumidifiers:
Recuperative (Phoenix)
Heat Pipe (Dri-Eaz)
LGR Dehumidifier~Recuperative
Wet air is
pulled
through
the heat
exchanger
Air In
This air is
passed
through
the
evaporator,
where it is
cooled.
This
cooling
causes the
moisture to
condense
from the
air
LGR Dehumidifier
Air Cooled
LGR Dehumidifier
This air is
then
directed
back
through
the heat
exchanger,
precooling the
incoming
wet air
Air
Pre-Cools
Incoming Air
LGR Dehumidifier
This now
slightly
warmer
air is
directed
through
the
condenser

air very

Heat Pipe LGR Dehumidifier
Heat Pipe :
A pair of
coils that
sandwich
the
evaporator
coil in order
to pre-cool
the
incoming
air stream.
Heat Pipe LGR Dehumidifier
The Heat Pipe is an
independent
charged
refrigeration
system without a
compressor or

Phoenix 200 HT
Bypass Technology
Bypass
allows
70% of
the
moisture
laden air
to pass
over the
heat
exchanger.
Air In
Bypass Technology
The
remaining
30% goes
behind the
heat
exchanger to
cool the
condenser.
This allows
the unit to
operate in
hotter
environment.
Air In
The bypass can
be turned off
when used at
normal
temperatures.
Ideal if used
with TES or ETES.
