How Much Pressure Should Be Added to a Car Air Conditioning Compressor?
1 Answers
When pressurizing a car air conditioning compressor, the low pressure should be between 1.0 to 2.5 bar, and the high pressure should be between 15 to 18 bar. The steps for pressurizing a car air conditioning system are: 1. Set the remote control to cooling mode and turn on the air conditioning; 2. Check if the indoor unit is operating normally; 3. Verify if the outdoor compressor starts properly; 4. After normal startup, connect the refrigerant charging equipment to the low-pressure valve side port of the outdoor unit; 5. Measure pressure and add refrigerant; 6. Use soapy water to check for any leaks. The car air conditioning compressor is a key component of the car air conditioning refrigeration system, responsible for compressing and transporting refrigerant vapor. Car air conditioning compressors are divided into fixed displacement compressors and variable displacement compressors.
