Hot water air-conditioner with multiple working modes

Abstract

The invention discloses a hot water air-conditioner with multiple working modes. The hot water air-conditioner comprises an outdoor unit carrying out heat exchange with the outdoor environment. The two ends of the outdoor unit are connected with an expansion valve and a four-way valve respectively. The other end of the expansion valve is connected with an indoor unit carrying out heat exchange with the indoor environment. The other end of the indoor unit is connected with a second connector of the four-way valve. A third connector of the four-way valve is connected with a compressor. The other end of the compressor is connected with a three-way valve I. The other two connectors of the three-way valve I are connected with a fourth connector of the four-way valve and a heat exchanger used for heating domestic water respectively. A three-way valve II used for controlling whether refrigerants flow through the indoor unit and / or a three-way valve III used for controlling whether the refrigerants flow through the outdoor unit are arranged between one end of the expansion valve and the four-way valve. By the adoption of the structure, the hot water air-conditioner can have the multiple different working modes and meet the requirements of different users.
