Why does the chiller evaporator freeze？
Oct 12 , 2021
During the use of the chiller, sometimes freezing occurs, and the chilled water malfunctions and alarms. The evaporator is one of the four core components of the chiller, and its importance is self-evident. Once it fails, the chiller will also go on strike. Today we will talk about the more common evaporator failures, namely Icing, to analyze the cause and find a solution. Why does the chiller fre...

How to control the temperature of the outlet water of the low-temperature chiller?
Nov 05 , 2021
The structure of low-temperature chillers is similar to that of piston chillers. Low-temperature chillers generally refer to chillers whose outlet temperature is less than or equal to 5°C. They are mainly used for process cooling in food processing, chemical, pharmaceutical and other industries. Low-temperature chillers are usually used for low-temperature requirements on certain special productio...

What are the differences between air-cooled chillers and water-cooled chillers
Jan 06 , 2022
We all know that according to different heat dissipation methods, chillers can be divided into air-cooled chillers and water-cooled chillers. What is the difference between air-cooled chillers and water-cooled chillers? 1. The air-cooled chiller uses copper tubes and aluminum fins to dissipate heat from the condenser. A fan is required to blow the outdoor air through the heat exchange fins and tak...
