A study of heat pumps, heat pump control circuits, defrost controls, auxiliary heat, airflow, and other topics related to heat pump systems. The student will be able to explain a reverse cycle system; list the mechanical and electrical components for the heat pump operation; and explain the operation of heat pump modes including cooling, heating, defrost, emergency heat, and auxiliary heat mode. Identify and explain the different methods of accomplishing defrost; charge a system correctly in the heating and cooling mode; troubleshoot electrical and mechanical components; perform tests for adequate airflow, and determine the balance point and co-efficiencies of performance (C.O.P.); and define attributes of geothermal heat pump systems.
