The fluorine refrigeration compressor is short of oil, how to add it?

When the compressor is running for a period of time, we can judge whether the compressor is short of oil by observing the oil glass. If the oil level in the oil glass is lower than half of the position, then we need to replenish the oil. This article introduces the oil replenishment method of small and medium-sized compressors.
