Common problems with refrigeration compressors (6)

Why shouldn’t the refrigerant recovery time of the air conditioner be too long?

The air conditioner should not be in operation for too long during the refrigerant recovery period. Because after the refrigerant recovery period is too long, the inhaled refrigerant gas will be extremely thin, and the exhaust temperature will be very high, causing the temperature of the compressor pump body parts to rise rapidly. The excessively high temperature causes the expansion degree of each part to differ too much, causing the matching clearance of some parts to become smaller or even disappear, and eventually causing abnormal scratches or wear.
