FIELD: power industry. ^ SUBSTANCE: hybrid-type heat pump system for heat and cold supply includes heat pump equipment, heat accumulation system, cold supply or air conditioning system, collection system of low-potential heat energy and utilisation system of secondary heat resources. Heat pump system is implemented as per hybrid scheme and connected to conventional heat supply system used as additional heat energy source or room terminal; at that, hydraulic circuit of heat accumulation system to which storage tanks are connected is closed and its heat carrier is hydraulically not connected to heat carrier of heating system and to water in hot water supply system. ^ EFFECT: increasing energy efficiency. ^ 6 cl, 1 dwg |
