U-Line ULN-SS1095 Manual De Usuario

• 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 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 
change that 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 then repeats
