systems with heat pumps. SUBSTANCE: heat pump has cooling agent circuit including compressor, oil separator, condenser, supercooler, throttling member, evaporator and oil circulation main line. The latter includes oil separator, additional oil cooler, oil pump and oil cooler connected with compressor. To increase heating capacity of heat pump and provide reliable operation, throttling member and heat exchanger-evaporator are additionally installed in heat pump cooling agent circuit. Heat exchanger-evaporator is installed after supercooler. Tube space of heat exchanger-evaporator is connected by pipelines with tube space of oil cooler which, in its turn, is connected with compressor. EFFECT: increased heating capacity and improved reliability. 1 dwg
