Industrial chillers-(singde) the basic requirements for the selection of lubricating oil!

Lubricating oil is to provide lubrication and cooling conditions for the moving parts of industrial chillers. The lubricating oil used in refrigeration compressors is usually called refrigerating oil, which is a highly refined special lubricant. Lubricating oil is used in the refrigeration compressor to lubricate the moving parts and reduce the friction between the surfaces of the moving parts.

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,

Variable-speed technology has become an essential component in the effort to improve HVAC equipment efficiency.

Variable-speed technology has become an essential component in the effort to improve HVAC equipment efficiency. The term “variable-speed” applies to two different components in an air conditioning or heat pump system: the blower motor and the compressor. 器2䀀

Cold storage anti-corrosion and anti-frost coatings effectively solve the problem of frosting and corrosion

In the cold storage, when the dew point of the air is lowered by the cooling pipe surface, the moisture in the food and air will precipitate and condense on the pipe wall. If the pipe wall temperature is lower than 0°C, it will condense into a rain layer.

Common failure phenomena of air-conditioning compressor

If your home's air conditioner is not cooling, it is likely that the compressor has malfunctioned. Why do you say this? Since the compressor is different from non-moving parts such as condensers and evaporators, it needs to run at high speed during system器2䀀

How to maintain the lubrication system of the chiller

In the operation system of the chiller, more attention is paid to the refrigerant circulation system, the chilled water circulation system and the electrical control system of the refrigerator. The lubrication system is often overlooked. As everyone knows, this system is also very important to the chiller.
