Compressor Tips:

How to judge whether the oil level and oil quantity of the compressor are appropriate.

There are two main types of confirmations:

1. Through the compressor mirror observation, observe whether the oil in the compressor transfers to the system abnormally under various working conditions (including special working conditions) and whether the oil level decreases at special time points.

2. During the test, the mixture of oil and refrigerant shall be intercepted, and the dilution ratio of test oil shall not exceed the allowable value.

Through the above measures, we can basically determine whether the oil return and refrigerant charge of a system is suitable for the reliability of the compressor. The compressor and the air conditioning system are compatible, and the simple test can not completely assess all the problems that may occur in the long-term operation.
