50Design ■ Features ■ PerformanceREFRIGERATION SYSTEMSNormal Vapor/Compression Cycle Refrigeration• Refrigerant is pumped from the compressor to the condenser as a high pressure, high temperaturevapor.• As the refrigerant cools in the high pressure condenser, the vapor condenses to liquid. During thisphase 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 tothe 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 satura-tion temperature. As the low temperature refrigerant passes through the evaporator coil, it continues toabsorb a lot of heat, causing the boiling action to continue until the refrigerant is completely vapor-ized. It is during this phase change that the most heat is absorbed (the cooling takes place) in the refrig-erator.• 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 tempera-ture. The hot high pressure gas is pumped out the discharge line and into the condenser. The cyclecontinues.CAPILLARY TUBEDRYERCONDENSERCOMPRESSOREVAPORATORUL183-12075R/2015R MODELS
