Particularly, compressor 1 has exhaust outlet and gas returning port, commutation assembly 2 has first to fourth valve port, and wherein, the first valve port is communicated with one of them in the 3rd valve port with the second valve port, 4th valve port and the second valve port are communicated with another in the 3rd valve port, that is, when the first valve port is communicated with the second valve port, the 4th valve port is then communicated with the 3rd valve port, when the first valve port is communicated with the 3rd valve port, the 4th valve port is then communicated with the second valve port.Preferably, commutation assembly 2 is cross valve, but is understandable that, commutation assembly 2 can be formed as other elements, as long as have first to fourth valve port and can realize commutating.
In addition, first valve port is also connected with exhaust outlet, and the 4th valve port is also connected with gas returning port, and the second valve port is connected with outdoor heat exchanger assembly 3,3rd valve port is suitable for being connected with the indoor heat exchanger of indoor set, is in series with restricting element between indoor heat exchanger and outdoor heat exchanger assembly 3.
Because in commutation assembly 2, the first valve port can commutate connection between the second valve port and the 3rd valve port, 4th valve port can commutate connection between the 3rd valve port and the second valve port, this makes multiple on-line system can change between refrigeration and heating mode, thus achieves refrigeration and the heat-production functions of multiple on-line system.
Such as, when the first valve port is connected with the second valve port, when 4th valve port is connected with the 3rd valve port, the gas of the HTHP after compressor 1 compresses is through the exhaust outlet of compressor 1, flow through the first valve port and the second valve port, enter into outdoor heat exchanger assembly 3, the cold of external environment is absorbed in outdoor heat exchanger assembly 3, form the liquid refrigerants of HTHP, then restricting element is entered, form the liquid refrigerants of low-temp low-pressure, enter into indoor heat exchanger subsequently with the heat in absorption chamber, with indoor environment heat exchange, the gaseous coolant of the low-temp low-pressure formed after heat exchange is by the 3rd valve port and the 4th valve port, and enter compressor 1 by the gas returning port of compressor 1, thus formation kind of refrigeration cycle, reciprocal with this.
When the first valve port is connected with the 3rd valve port, when 4th valve port is connected with the second valve port, the gas of the HTHP compressed through compressor 1 is through the exhaust outlet of compressor 1, flow through the first valve port and the 3rd valve port, enter into indoor heat exchanger, with the cold in absorption chamber in indoor heat exchanger, form the liquid refrigerants of HTHP, then restricting element is entered, the liquid refrigerants forming low-temp low-pressure after restricting element reducing pressure by regulating flow enters into the heat outside outdoor heat exchanger assembly 3 absorption chamber, form the gaseous coolant of low-temp low-pressure subsequently through the second valve port and the 4th valve port, and enter compressor 1 by the gas returning port of compressor 1, thus formation heats circulation, reciprocal with this.
