Thesis in the introductory section describes the theory of heat pumps, the principle of their functions, including components used in pumps. The thesis includes a description of the air-water heat pump indoor unit, which also includes a frequency converter. Electronic frequency converter produces waste heat that must be cooled. The most extensive part of the work therefore deals with the computational model of heat transfer in the exchanger. The output is a map of all heat pump operating points with checking cooling efficiency of the inverter. In the final part are recommended modifications of the cooler design.
