What Causes Frequent Cycling of the Compressor?
1 Answers
Frequent cycling of the compressor is caused by: blockage in the air conditioning system, electrical system failure, insufficient refrigerant, overly tight drive belt, erroneous signals from various sensors, excessively high or low exhaust pressure, low adjustment value of the high-pressure relay, high adjustment value of the low-pressure relay, insufficient or excessive refrigerant. Solutions for frequent compressor cycling: 1. Use high-pressure nitrogen to flush the pipelines; 2. Increase the expansion valve opening to adjust the suction pressure; 3. Increase the cooling water flow to reduce the exhaust pressure; 4. Appropriately raise the limit value of the high-pressure relay and lower the limit value of the low-pressure relay; 5. Regularly check the remaining amount of refrigerant.
