Abstract
A method for controlling a heat pump including an outdoor unit including a compressor and a first heat exchanger, an indoor unit including a second heat exchanger and an expansion valve to perform air stream cooling and heating operations, and a hydro unit connected among the compressor, the first heat exchanger, and the expansion valve, to change a flow direction of refrigerant in accordance with cold water and hot water operations. In the control method, it is determined whether the hot water operation and the air stream heating operation are simultaneously selected. When the hot water operation and the air stream heating operation are simultaneously selected, an opening degree of a valve included in the hydro unit is adjusted, to adjust amounts of refrigerant respectively supplied from the compressor to the hydro unit and the indoor unit.
