Embodiment Construction

[0026] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0027] like figure 1 System diagram of the three-pipe air conditioning and hot water system shown. The system diagram is divided into external machine part, internal machine part and water tank part.

[0028] The outdoor unit is a three-pipe outdoor unit 10, which has two four-way valves, namely a first four-way valve 12 and a second four-way valve 13. The D ends of the first four-way valve 12 and the second four-way valve 13 are both connected to the exhaust of the compressor 11 , and both the S ends are connected to the air intake of the compressor 11 . The C end of the first four-way valve 12 is connected to the outdoor heat exchanger 14, and there is an outdoor electronic expansion valve 15 between the outdoor unit and the small valve 16 for controlling the degree of superheat / subcooling. The E end of the first four-way valve 12 is connected with a ...
