Working Principle of the water chiller
May 17 , 2021
Chillers are divided into air-cooled chillers and water-cooled chillers. The working principle diagram of air-cooled chillers is as follows Working Principle of air-cooled chiller The air-cooled chiller uses a shell and tube evaporator (or tank with coil) to exchange heat between water and refrigerant. The refrigerant system absorbs the heat load from the water and cools the water to produce cold ...

What is a industrial chiller ?
May 17 , 2021
Industrial chillers are one type of chillers, and chillers can be divided into air-cooled chillers and water-cooled chillers. Water chiller is a kind of water cooling equipment, which can provide constant temperature, constant current and constant pressure cooling equipment. The principle of the chiller is to inject a certain amount of water into the internal water tank of the machine, and the wat...

Analysis of the advantages and disadvantages of air-cooled screw chillers and air-cooled scroll chillers
Jul 16 , 2021
Both air-cooled screw chillers and air-cooled scroll chillers are air-cooled chillers. Air-cooled chillers use air cooling, eliminating the need for cooling towers, cooling water pumps and piping systems that are essential for cooling water systems. Areas with poor water quality cause condenser fouling and water pipe blockage, and also save water resources. It is the most economical and simple mod...

Solutions to failures of air-cooled screw chillers
Jul 23 , 2021
The air-cooled screw chiller is a screw chiller that uses fans to dissipate heat. The installation environment it needs must be open and easy to circulate, so that this operation will not affect the cooling effect of the air-cooled screw chiller . Therefore, we should understand some common faults of air-cooled screw chillers and some troubleshooting methods: 1. The fan noise of the ...

How to choose a suitable pump for the chiller
Aug 20 , 2021
In a chiller cooling water system, the water pump is an indispensable component. The water pump can be installed in the chiller or outside the chiller. Generally, we install the water pump in the chiller unit for air-cooled chillers. , So that the chiller is easy to install. For a water-cooled chiller, a system requires at least two water pumps. One pump is installed in the chiller to provide chil...
