Heat Pumps for Heating and Cooling being used, and the operating temperature in the evaporator. 1 ton of refrigeration is equivalent to 12000 BTU’s/hour. • The evaporator is a heat exchanger where the refrigerant vaporizes; i.e. it absorbs heat and the surroundings get cold. • The condenser is a heat exchanger where the refrigerant condenses; i.e. it releases heat and the surroundings get hot. • Expansion valve is a device used to reduce the pressure and temperature of the refrigerant at the end of the process cycle. Lowering the pressure of the refrigerant allows it to vaporize once heat is added. The basic arrangement of a refrigeration circuit (cooling mode) is shown below: Let’s see how this cycle works. • Stage1 − Refrigerant enters the evaporator in the form of a cool, low- pressure mixture of liquid and vapor. Heat is transferred from warm indoor air to the refrigerant; causing the liquid refrigerant to boil. • Stage 2 − The refrigerant vapor from the evaporator now enters the compressor, where its pressure (and hence temperature) is increased. 6PDF Image | Heat Pumps for Heating and Cooling
