Compressor's influence on walk-in cooler

Compressor's influence on walk-in cooler Compressor operation non-stop feature and maintenance Walk-in cooler Compressor non-stop operation can generally be divided into two categories: one is walk -The temperature inside the walk-in cooler in cooler cannot meet the shutdown requirements of the thermostat; the second is that the temperature inside the walk-in cooler meets the refrigeration r...

The role of valves and meters in commercial refrigeration

the role of valves and meters in commercial refrigeration installation of valves and measuring instruments all kinds of valves (except safety valves with lead seals) need to be disassembled and cleaned before installation to remove oil and rust. The valve is cleaned with kerosene for sealing test. The cleaned valve is opened and closed 4 to 5 times before oil injection, and then kerose...

The blow-in and air-tightness of the walk-in cooler refrigeration system

The blow-in and air-tightness of the walk-in cooler refrigeration system After the blow-in refrigeration system is installed, it is inevitable that there will be welding slag, rust, oxide scale and other impurities in the system. If it is not cleaned up, impurities will damage the valve core when the refrigeration device is running; passing through the cylinder, the mirror surface of the cylin...

display cases The influence of airtightness

display cases The influence of airtightness display cases The refrigerant in the refrigeration device has a strong permeability. If the device is not tight, it will cause a large amount of refrigerant leakage and affect the refrigeration device normal work. At the same time, some refrigerants are also toxic, such as ammonia, which is harmful to the human body after leakage: Although Freon is n...

The effect of commercial refrigeration vacuum leak test

The effect of commercial refrigeration vacuum leak test Vacuum leak test is performed after the pressure leak test is completed. There are two purposes of the vacuum leak test, one is to check the tightness of the commercial refrigeration system under vacuum conditions, and the other is to remove the residual gas and moisture in the system. Non-condensable air or nitrogen will not condense i...
