Abstract:
1. A method for controlling a hot water circulation system associated with a heat pump, the hot water circulation system comprising an outdoor unit including a compressor, an outdoor heat-exchanger having a refrigerant pipe, a first sensing device to sense a temperature T 1 of the refrigerant pipe, an expansion part and an outdoor fan; an indoor unit including a water-refrigerant heat-exchanger which performs heat exchange between a refrigerant discharged from the compressor and water, a second sensing device to sense a temperature T 2 within a water pipe of the water refrigerant heat exchanger, a water collection tank in which water passing through the water-refrigerant heat-exchanger is stored, and a water pump which pumps water discharged from the water collection tank; a hot water circulation unit which receives heat from the water pumped from the water pump to perform hot water supply or heating, the hot water circulation unit including a hot water supply tank in which water supplied from the outside of the hot water circulating unit is stored and an auxiliary heater provided in at least one of the water collection tank and the hot water supply tank wherein the method comprises: sensing temperature T performing a first operation including reducing an operating rate of the compressor, reducing a velocity of the outdoor fan, and controlling an opening of the expansion part when the temperature T sensing the temperature T performing a second operation including at least one of driving of the auxiliary heater and reducing an output of the water pump when the temperature T
