The purpose of the work is the formation of target indicators of the technological efficiency of the use of a heat pumping unit in the design and climatic conditions of Northern Kazakhstan on the example of the Kostanay region. The result of the proposed solutions are piecemeal studies of exergy losses of the real thermodynamic cycle of a heat pump installation in the climatic conditions of the Kostanay region. The calculations have shown that the main source of exergy loss is the condensate cooler and the condenser. The exergy losses in the remaining elements of the thermodynamic cycle were found to be insignificant. The main way to reduce exergy losses in the further study of scientific and technical problems of using thermal pumps in the Kostanay region is the correct choice of architecture of heat exchange equipment, which allows to reduce the relative level of their losses in the overall exergy balance to a minimum.
