How to Deal with Water Intrusion in the Refrigeration System?
2 Answers
Methods for handling water intrusion in the refrigeration system: First, disassemble the components of the refrigeration system, use nitrogen pressurization followed by instantaneous release to blow out as much moisture as possible from the components. Ensure that most of the moisture in the system is removed, then reassemble the refrigeration system and restart the operation. The following is an introduction to the refrigeration system: 1. The refrigeration system of a car air conditioner mainly consists of the evaporator, air conditioning compressor, condenser, liquid storage tank, expansion valve, and high and low-pressure pipelines. 2. If the refrigerant in the refrigeration system is insufficient, the evaporator will 'stop vaporizing,' and the compressor's intake pressure will also decrease. Even if the refrigeration system is still running, the air temperature in the car cabin will rise.
Dealing with water ingress in the refrigeration system is quite common in my experience. Last time my car's air conditioning malfunctioned, it was due to accidental water entry during car washing. When water gets into the refrigeration system, it can cause the compressor to rust and fail, and may even lead to short circuits or fire hazards, which are extremely dangerous. The first step is to immediately turn off the air conditioning and the engine to prevent further damage. Then, take the car to a professional repair shop for inspection. They will use a vacuum pump to remove the water and clean the entire system, including the evaporator and condenser. If not cleaned thoroughly, residual moisture can mix with the refrigerant, forming acids that corrode components. Long-term inactivity of the air conditioning can also lead to mold growth and unpleasant odors, affecting health. Repair shops typically replace damaged seals and filters, then recharge the system with new refrigerant for testing. Remember, avoid DIY fixes like using a hair dryer or ventilating with open windows, as these can damage electronic components. Regularly check the air conditioning drain holes for blockages during maintenance, and avoid spraying high-pressure water at the air conditioning vents during car washes to prevent issues in advance.
