This module discusses the design and operation of the equipment used in vapor-compression refrigeration systems. The compressor is the heart of the system; it adds the energy that is needed to transfer heat out of the system and it causes the refrigerant to flow. As the refrigerant travels around the closed loop system, moving heat from one location to another, it flows through a system of piping, tubing, fittings, and valves. Several types of valves are used, and the most important is the expansion valve. The expansion valve controls the flow of refrigerant to the evaporator, which ultimately determines the capacity of the system. Other valve types, receivers, liquid-line filter driers, and accumulators are also covered.
