This application relates to the technical field of heat pump equipment, specifically disclosing a photovoltaic direct-drive high-efficiency heat pump based on a special refrigerant. It includes a compressor, a first heat exchanger, a second heat exchanger, and a heat exchange circuit. The compressor compresses the refrigerant into a high-temperature, high-pressure gas. The first heat exchanger is connected to the compressor and is used to exchange heat between the refrigerant and domestic water to heat the domestic water. The second heat exchanger is used to exchange heat between the refrigerant and circulating water to heat or cool the circulating water. The heat exchange circuit includes a four-way valve, a bridge valve assembly, a liquid receiver, an economizer, and an evaporator. The four-way valve is connected to the compressor, the first heat exchanger, the second heat exchanger, and the evaporator. The bridge valve assembly is connected to the second heat exchanger, the economizer, the liquid receiver, and the evaporator. The liquid receiver is connected to the economizer, and the economizer is connected to the compressor. This application improves the utilization efficiency of the heat pump.
