Working principle of three-flower four-way valve
The three-flower four-way valve is an important part of the heat pump type air conditioner. It has the function of changing the flow direction of the air conditioner refrigerant, so that the air conditioner can realize the cooling and heating function without adding other heating elements. It can play its role, mainly due to the working principle of the four-way valve, as shown below:
1. Refrigeration principle
When the air conditioner is in the cooling state, the three-flower four-way valve is not energized, and is in a state of no electrical connection and no electrical connection. The refrigerant is compressed into high-temperature and high-pressure gas by the compressor, passes through port a of the four-way valve, is discharged from port d, and enters the outdoor heat exchanger. After the condenser is cooled, it becomes a medium-temperature and high-pressure liquid. After passing through the expansion valve, it becomes a low-temperature and low-pressure liquid. After the indoor heat exchanger is cooled, it becomes a low-temperature and low-pressure gas. Keep looping.
2. Heating principle
When the air conditioner is in the heating state, the four-way valve is energized and the piston moves to the right to connect ab and cd. The refrigerant is compressed into high temperature and high pressure gas by the compressor, and enters the indoor heat exchanger through port a of the four-way valve and exit b of the four-way valve. The condenser becomes a medium temperature and high pressure liquid after cooling, and becomes a low temperature and low pressure liquid after being cooled by an expansion valve, and becomes a low temperature and low pressure gas after being cooled by an outdoor heat exchanger.
The above is the whole content of the working principle of the three-flower four-way valve introduced by the editor. I hope you can have a better understanding of it after reading it. If there is anything else you want to know, please contact us.
