Heat pump heating-cooling system using hybrid heat source and control method thereof

摘要

Disclosed is a heat pump heating/cooling system that uses a hybrid heat source that may include air heat, groundwater heat, brine and in-line heaters. The heat pump includes 1) a device for compressing, condensing, gasifying, and circulating cooling/heating media and exchanging heat with water refrigerant; 2) a device for storing heat energy in a storage tank; 3) a device for loading a load through a four-way fan coil unit; and 4) a control panel. To remove frost on the exterior of an evaporator, the evaporator is temporarily stopped, and brine at a temperature of 15° C. to 20° C., which receives groundwater heat from a brine heat exchanger and receives heat from an in-line heater, is supplied to a brine supply pipe installed around the evaporator to melt and remove the frost on the exterior of the evaporator and then is discharged at a temperature of −3° C. to 5° C.
