- Product Description
-
- Commodity name: Refrigerant pressure sensor
- Commodity ID: HM8400S
The high pressure sensor and the low pressure sensor are installed on the discharge and return air pipes of the compressor respectively. The refrigerant pressure sensor of the automobile air conditioner is installed in the high-pressure pipeline between the condenser and the evaporator.
What is the effect of the refrigerant pressure sensor on the air conditioner?
Some AC systems have low-pressure safety devices that can shut down the compressor if the pressure on the suction side is too low. Some AC systems have a high pressure safety that shuts down the compressor when the discharge side pressure is too high. Some communication systems have both. The safety device is designed to prevent catastrophic damage. Some AC systems have an environmental switch and a pressure switch on the exhaust side, which can prevent the exhaust pressure from being too low. Turn off the condenser fan to increase the pressure, and turn it back on once a certain pressure is reached. In this way, the discharge pressure can be maintained when the outdoor is colder.
