Refrigerant is pumped from the compressor to the condenser as a 
high pressure, high temperature vapor.

As the refrigerant cools in the high pressure condenser, the vapor 
condenses to liquid. During this phase change, a great amount of 
heat is rejected with the help of the condenser fan.

The liquid then flows to the dryer where it is strained and filtered.

From the dryer, the refrigerant flows through the capillary tube 
which meters the liquid refrigerant to the evaporator. The 
pressure of the refrigerant is reduced to the evaporating or low 
side pressure.

The reduction of pressure on the liquid refrigerant causes it to boil 
or vaporize until it reaches saturation temperature. As the low 
temperature refrigerant passes through the evaporator coil, it 
continues to absorb a lot of heat, causing the boiling action to 
continue until the refrigerant is completely vaporized. It is during 
this phase that the most heat is absorbed (the cooling takes place) 
in the refrigerator.

The refrigerant vapor leaving the evaporator travels through the 
suction line to the compressor inlet. The compressor takes the 
low pressure vapor and compresses it, increasing both pressure 
and temperature. The hot high pressure gas is pumped out the 
discharge line and into the condenser. The cycle continues

• The unit is equipped with a four-minute compressor off cycle.
