What is the problem when the low-pressure pipe of a car's air conditioner freezes?
1 Answers
Reasons for the freezing of the low-pressure pipe in a car's air conditioner: 1. The expansion valve is faulty, preventing it from sensing the real-time temperature of the low-pressure pipe. If the temperature is too low, the low-pressure pipe will definitely freeze. However, this situation is basically irreparable, and a new expansion valve needs to be replaced; 2. The evaporator temperature sensor fails. When the temperature is below 2 degrees Celsius, the air conditioner will stop operating to prevent frost and freezing. The car air conditioning system, abbreviated as car AC, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to a suitable state.
