Signs of normal operation of cold storage room
Some customers will ask what the state of the cold storage room is during normal operation. Today, I will give you a popular science knowledge about the normal operation of the CBFI cold storage room . 1. There should be no noise in the cylinder, only the normal and regular cold storage sound of the suction valve. 2. The suction temperature of the compressor should be 5-15℃ higher than the evaporation temperature (R22). 3. The condenser cooling water in the cold storage room should be sufficient, the water pressure should be above 0.12mpa, and the water temperature should not be too high. 4. For the new series of products, the reading of the oil pump pressure gauge should be 0.15-0.3mpa higher than the suction pressure 5. There should be no foot heating and frosting on the cylinder wall, and the surface temperature difference should not be greater than 15-20 degrees. For refrigerated or low-temperature systems, frosting of the suction pipe can generally r...
