FIELD: heat-power engineering, heating systems, hot water supply systems and air-conditioning systems. SUBSTANCE: output of thermal pump is increased due to increase of temperature of heat-transfer agents: water for evaporation of cooling agent and central heating system water through recovery of heat released in course of heat exchange in thermal pump elements and supply of heated heat-transfer agents for mixing with high-temperature water escaping from thermal pump and water for evaporation of cooling agent delivered from low-potential heat source. Thermal pump is provided with water-jet ejector mounted at evaporator inlet. Working nozzle of this ejector is connected with pipe line running from low-potential heat source and injected nozzle is connected with lines running from subcooler, oil cooler and storage tank through electromagnetic valves controlled by level sensors fitted in storage tank. EFFECT: increase of high-potential heat taken off thermal condenser up to 20 percent. 3 cl, 2 dwg |
