How to deal with the blockage of industrial chillers

Usually, after a long period of use of the industrial chiller, some failures will inevitably occur. Among them, the blockage caused by the inlet and outlet of the capillary will affect the working status of the entire equipment and cause the cooling performance to decrease.

Common practice of oil return design in refrigeration system

When the condenser is installed higher than the compressor, a U-shaped bend is required at the intake pipe of the condenser to prevent oil from returning to the exhaust side of the compressor during shutdown and also help prevent liquid refrigerant from the condenser

The difference between air-cooled and water-cooled screw air compressors

The difference between air-cooled screw machine and water-cooled screw machine: 　　The oil cooler of the air-cooled screw compressor and the compressed air after-cooler are made into one body. It is an aluminum plate-fin structure and brazed in a vacuum furnace. Once the oil leaks, it is almost irreparable and only replaced. The working principle is that hot oil and high temperature (about 80℃) gas flow in their respective pipes,
