That is, the present invention uses the first three-way valve 40 and the second three-way valve 50 to replace the four-way valve in the prior art, so as to separate the suction line and the discharge line of the compressor 10, thereby solving the problem of temperature loss caused by the simultaneous connection of the suction line and the discharge line with the four-way valve in the prior art.
The invention also discloses a method for controlling the temperature of the four-way valve, which is characterized in that the structure that the flow direction of a refrigerant is switched by the four-way valve which is usually adopted in the prior art is changed, the function of the four-way valve is realized by adopting the matching control of the two three-way valves, the temperature loss of the traditional four-way valve caused by the close distance between a suction pipe and an exhaust pipe can be effectively avoided, the system efficiency is improved, meanwhile, the three-way valve has no narrow channels such as capillary tubes and the like, and has no phenomena such as blockage and the like, in addition, the interior of the.
The invention also provides a control method of the compressor system, and specifically, when the compressor system is in refrigeration operation, the fourth valve port 4 and the sixth valve port 6 of the second three-way valve 50 are controlled to be communicated, and the first valve port 1 and the second valve port 2 of the first three-way valve 40 are controlled to be communicated. When the compressor system is operated for heating, the fourth port 4 and the fifth port 5 of the second three-way valve 50 are controlled to communicate with each other, and the first port 1 and the third port 3 of the first three-way valve 40 are controlled to communicate with each other.
The control method and the operation principle of the compressor system of the present invention will be specifically described with reference to fig. 1.
When the compressor system is set in a refrigeration and dehumidification mode, at the moment, the first three-way valve 40 and the second three-way valve 50 are powered on and operated at the same time, at the moment, the first valve port 1 and the second valve port 2 of the first three-way valve 40 are communicated, the first valve port 1 and the third valve port 3 are closed, the fourth valve port 4 and the sixth valve port 6 of the second three-way valve 50 are communicated, the fourth valve port 4 and the fifth valve port 5 are closed, and the specific refrigerant flow direction is as follows:
the high-temperature and high-pressure gas discharged from the compressor 10 firstly passes through the fourth valve port 4 and the sixth valve port 6 of the second three-way valve 50, then the refrigerant flows through the outdoor heat exchanger 30, then passes through the throttling mechanism to reach the indoor heat exchanger 20, and finally flows back to the compressor 10 through the second valve port 2 and the first valve port 1 of the first three-way valve 40, thereby completing the refrigeration cycle.
When the compressor system is in the heating mode, the first three-way valve 40 and the second three-way valve 50 are powered on simultaneously, at this time, the first port 1 and the third port 3 in the first three-way valve 40 are communicated, the first port 1 and the second port 2 are closed, the fourth port 4 and the fifth port 5 in the second three-way valve 50 are communicated, and the fourth port 4 and the sixth port 6 are closed, and the specific refrigerant flow direction is as follows:
the high-temperature and high-pressure gas discharged from the compressor 10 first passes through the fourth valve port 4 and the fifth valve port 5 of the second three-way valve 50, then the refrigerant flows through the indoor heat exchanger 20, then passes through a throttling mechanism such as an electronic expansion valve to reach the outdoor heat exchanger 30, and finally flows back to the compressor 10 through the third valve port 3 and the first valve port 1 of the first three-way valve 40, thus completing the heating cycle.
That is, in the invention, the double three-way valve is adopted for controlling, the double three-way valves synchronously act and switch, and the flow path of the refrigerant is changed, thereby realizing the switching of the flow direction of the refrigerant. Because the distance of the double three-way valves is far, the temperature loss of the traditional four-way valve caused by the close distance of the suction and exhaust pipes can be effectively avoided, the system efficiency is improved, and meanwhile, the three-way valves do not have narrow channels such as capillaries, the phenomena of blockage and the like, and simultaneously, the sliding blocks do not exist, and the problem that the sliding blocks are blocked does not exist
