Heat pump air conditioning system using composite heat source and control method thereof

摘要

The present invention includes: i) a thermal energy generator that compresses, condenses, vaporizes, and circulates a cold medium and supplies heat to the water-refrigerant heat exchanger (B); and ii) a thermal energy storage / cold storage tank (E) A heat pump air-conditioning system using a composite heat source, comprising: a device for storing the heat energy; iii) a device for supplying thermal energy to the load via the four-way fan coil unit (F); and iv) a control device (10). , The operation of the evaporator (D) is temporarily stopped for defrosting outside the evaporator, and groundwater heat supplied from the brine heat exchanger (20) and heat supplied from the in-line heater (40) are provided. 15-15 ° C. brine was installed around the evaporator and supplied to the brine supply pipe (C) to melt frost outside the evaporator, and then discharged with -3-5 ° C. brine to form frost. To remove Air heat of the butterfly, groundwater heat, brine heat, on heat pump heating and cooling system that uses a composite heat source such as an inline heater heat. [Selection] Figure 1
