• Dehumidifier that works at an evaporator

temperature of over 0

o

C (32

o

F).

Heat absorption by the refrigerant will

depend on the evaporator temperature.

A certain pressure corresponds to a

certain temperature in the evaporator.

The gas density is higher at low

temperatures and, therefore, only a small

quantity of heat may be absorbed during

evaporation. If there is evaporation at a

higher temperature, for instance, 0

o

C

(32

o

F), the pressure and density will

increase and more heat will be absorbed.

For this reason, we can conclude that

the work required by the motor in a

compressor for a high evaporation

temperature will be more than that

required by the same compressor at a

low evaporation temperature.

Consequently, motors to be used in high

evaporation pressure systems must have

a higher operating torque.

The compressors can be classified

according to their use as follows:

HBP – High Back Pressure

High evaporation temperature

MBP – Medium Back Pressure

Medium evaporation temperature

LBP – Low Back Pressure

Low evaporation temperature
