How to avoid overheat protection of scroll Copeland compressor

How to avoid overheat protection of scroll Copeland compressor Friends who have used Copeland compressors know that Copeland compressors are relatively solid to use and are not so easily damaged. This is because Copeland compressors have several built-in protection programs. Overheat protection is one of them. Today we will talk about the internal temperature protector of the scroll compressor. Whether it is the TOD temperature protection device on the ZB15-ZB48 (ZF06-ZF25) compressor, or the ASTP temperature protection device on the ZB58-ZB114 compressor. All are temperature-sensitive quick-acting valve parts installed in the vortex exhaust port. When the exhaust temperature is too high, it will open to let the high temperature exhaust return and contact the motor protector, thereby protecting the Copeland compressor.

How to avoid overheating the scroll Copeland compressor? We have the following suggestions: 1. Do not use a compressor to vacuum the system when vacuuming. 2. Refrigerant charging: 2-1. After vacuuming, the refrigerant should be charged from the high and low pressure sides at the same time. 2-2. Try to complete the maximum charge before the compressor is turned on. 2-3. Do not close the liquid supply valve, let the system replenish the refrigerant liquid from the low pressure side after normal operation. 3. Setting of pressure system. The shutdown pressure of the Copeland compressor should not be lower than the evaporating pressure value corresponding to the minimum evaporating temperature of the compressor. These are some suggestions for avoiding overheating of scroll Copeland compressors.
