How to repair the fault of the excavator produced by the micro excavator manufacturer?
1. Transpiration apparatus
The evaporator circulates the liquid refrigerant through an expansion valve to absorb the heat of the air inside the car, and uses a transpiration fan to drive cold air into the car.
2. Expansion valve
The expansion valve depresses the high-temperature and high-pressure refrigerant liquid to become a low-temperature and low-pressure mist refrigerant (that is, the high-pressure side is separated from the low-pressure refrigerant). Simply transpiration into the steamer
3. Temperature sensor
Investigate the temperature of the evaporator to prevent the evaporator from freezing, and manipulate the suction of the compressor to bring the room temperature to a certain condition.
4. Inside air filter
Both internal and external dust and other foreign objects are blocked. Note: Should be cleaned or replaced regularly (about 6 months).
5. Compressor:
After being driven from the engine belt, the low temperature/low pressure refrigerant that is steaming from the evaporator is compressed into high temperature and high pressure gaseous refrigerant and transported to the condenser.
6. Condenser repair excavator
The high temperature/high pressure refrigerant gas sent from the compressor is converted into a high temperature and low pressure refrigerant liquid.
When the chip is tilted or damaged, or the exterior is contaminated with foreign matter (mud, grass, etc.), abnormal high pressure will occur, which will cause the cooling function to decrease.
The repair methods of mini excavator air conditioning problems are these, and I hope to help you.
