FIELD: heat-power engineering, air-conditioning systems, cold supply systems, gas regenerative machines working by reverse Stirling cycle. SUBSTANCE: proposed unit is provided with cooling system for cooling the refrigerating machine placed in operation by means of electric motor; this cooling system connects the cooler of refrigerating machine with load heat exchanger of thermal pump. Due to delivery of external energy from electric motor, heat of cooling liquid of cooling system is transferred to heat-transfer agent of external heat supply system flowing through cooler of thermal pump, thus raising its temperature. Temperature of cooling liquid gets equalized in intermediate reservoir to surrounding temperature due to heat exchange with surrounding medium. To this end, intermediate reservoir is provided with finned inner and outer surfaces, perforated upper cover and spraying injector. Cooling liquid is returned from reservoir to cooler for cooling the refrigerating machine by means of pump. EFFECT: enhanced efficiency of thermal pump and plant as a whose. 1 dwg
