This is another in a series of columns addressing advanced basics in the understanding of the refrigeration cycle. In this column, we continue our look at components. The June 6 column ("The Basic Refrigeration System") dealt with the compressor, discharge line, and condenser. This column will focus on the receiver, liquid line, metering device, evaporator, and suction line. In each case, details will be given as to the component's function.
Mastering the function of each individual component can assist the technician with analytical troubleshooting skills. In the long run, this will save time and money for both technician and customer.
