The conditions of efficient use of heat pumps in air conditioning systems are considered in order to ensure the established temperature and relative humidity of air in premises with the removal of excess moisture in the warm or hot periods of the year. For this purpose, a thermodynamic analysis of heat pump air conditioning schemes with exhaust air recirculation through a condenser and through a heat pump evaporator has been carried out. To determine the potential capabilities of such schemes to maintain comfortable conditions in the production room, a numerical analysis of their operating parameters, depending on the temperature and relative humidity of external atmospheric air, was performed. It has been shown that recirculation of exhaust air through the heat pump evaporator allows to maintain the given conditions in the room in a wider range of parameters of external atmospheric air. In addition, it has been shown that such a scheme requires less specific energy consumption for the operation of heat pump, which means that it is more efficient.
