Abstract

A heat pump and a method for operating a heat pump are provided. The heat pump may include an outdoor unit including a compressor that compresses a refrigerant and an outdoor heat exchanger that exchanges heat between the refrigerant and outdoor air, a hybrid unit including at least one fluid-refrigerant heat exchanger that exchanges heat between the refrigerant supplied from the outdoor unit and a fluid, such as water, and at least one refrigerant control valve that controls an amount of refrigerant flowing through the at least one fluid-refrigerant heat exchanger, a plurality of indoor units each including an indoor heat exchanger that exchanges heat between the fluid supplied from the hybrid unit and indoor air, and a controller. The controller may calculate operation loads of the plurality of indoor units and control an opening degree of the at least one refrigerant control value based on the operation loads of the plurality of indoor units.
