Hot Air Conditioner

The invention relates to a hot water air conditioner which comprises an air conditioner and a water heater, wherein a refrigerant outlet in the compressor is connected with one end of a tee pipe joint A through a pipeline; the other two ends of the tee pipe joint A are respectively connected with inlet ends of a normally open valve and a normally closed valve; an outlet end of the normally open valve is connected with the refrigerant inlet in a heat exchanger in the water heater through a pipeline; the refrigerant outlet in the heat exchanger is connected with one end of a tee pipe joint B through a pipeline; the other two ends of the tee pipe joint B are respectively connected with an outlet end of the normally closed valve and the refrigerant inlet end of a four-way reversing valve in the air conditioner; and the refrigerant is discharged from the refrigerant outlet of the compressor and then flows into a condenser through the pipeline, the normally open valve, the heat exchanger and the four-way reversing valve, and flows back to a refrigerant backflow inlet of the compressor through an expansion valve, an evaporator and the four-way reversing valve or flows into the evaporatorthrough the four-way reversing valve and flows back to the refrigerant backflow inlet of the compressor through the expansion valve, the condenser and the four-way reversing valve. The invention can enhance the heat exchange efficiency of the hot water air conditioner and fully utilize heat energy.
