Claim Text:
1. 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, the method comprising: determining by a controller whether the hot water operation and the air stream heating operation are simultaneously selected; controlling, by the controller, an adjusting of an opening degree of a valve included in the hydro unit when the hot water operation and the air stream heating operation are determined by the controller to be simultaneously selected, to adjust amounts of refrigerant respectively supplied from the compressor to the hydro unit and the indoor unit; wherein controlling, by the controller, the adjusting of the opening degree of the valve included in the hydro unit comprises: identifying by the controller a capacity of the indoor unit; selecting by the controller an opening degree of the valve such that the selected opening degree corresponds to the identified capacity of the indoor unit; compensating, by the controller, the selected opening degree, based on a detected outdoor temperature; and, controlling, by the controller, the adjusting of the opening degree of the valve such that the adjusted opening degree corresponds to the compensated opening degree.
