Abstract
A heat pump and a control method thereof are provided. The heat pump includes an outdoor unit includes a compressor that compresses a first refrigerant, a first outdoor heat exchanger that exchanges heat between the first refrigerant and outdoor air, an expansion mechanism that expands the first refrigerant, and a second outdoor heat exchanger that exchanges heat between the first refrigerant and a second refrigerant; a first refrigerant pipe that connects the compressor, the first outdoor heat exchanger, and the expansion mechanism, and through which the first refrigerant flows; a pressure sensor disposed in the first refrigerant pipe; a second refrigerant pipe connected to the second outdoor heat exchanger, and through which the second refrigerant flows; an indoor heat exchanger that is disposed in the second refrigerant pipe, and exchanges heat between indoor air and the second refrigerant; and a controller that determines a supply of the second refrigerant by determining a flow rate of the second refrigerant based on surging occurring in a pressure of the first refrigerant measured by the pressure sensor, so that the flow rate of the second refrigerant flowing through the secon…
