Requirements for adding refrigerant to industrial chiller system
Jul 30 , 2021
After the industrial chiller system has passed the vacuum test, the vacuum state in the system can be used to charge the refrigerant. 1. Refrigerant charging For newly installed systems, refrigerant can be added to the high-pressure end, and the operation method is as follows: 1) Turn on the cooling water system for the condenser, and keep the valve in the system as it was during the vacuum test 2...

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 ...

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...

How to clean a water chiller?
Jun 05 , 2021
How to clean a water chiller? As a fixed asset of an enterprise, the chiller is a must for enterprise personnel to maintain it and maximize its usefulness. Because the long-term operation of the chiller will cause thick scale on the surface of the condenser, which will interfere with the normal operation of the chiller. For example, to make its work efficiency low or easy to damage, etc., the nece...

What caused poor refrigerating efficiency ?
Jun 02 , 2021
What caused poor refrigerating efficiency? Sometimes when we use a chiller, but the temperature could not be lower, or After cooling down to a certain temperature, it won’t go down anymore. Let's talk What caused the poor refrigerating efficiency ? 1. Refrigerant leakage [fault analysis] After the refrigerant leak in the system, the cooling capacity is insufficient, the suction and exhaust pressur...

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...

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 ...
