How to help pharmaceutical factories to save electricity on HVACR system
2019-08-30
The raw material medicine is mainly produced by raw material fermentation or chemical synthesis. No matter which production process needs to be carried out at a relatively stable low temperature. Different medicines require different temperatures, such as antibiotic raw materials need to be maintained at around 25 °C during fermentation, other chemical raw materials are produced at tempe...

The Solutions of Common Low Pressure for Chillers
2019-07-26
There are many factors that cause low-pressure failure of cold water (freezer) machines, and we only list some of them today. It can be roughly divided into the following categories (from easy to difficult sequence) system leakage, system blockage, and evaporator blockage. Important: The "Reset button" on the pressure controller must be pressed after each fault point has been processed. Common low...

Analysis of 10 major failure phenomena commonly seen in refrigeration equipment maintenance
2019-07-05
1. The exhaust gas temperature of the refrigeration system is too low: The low exhaust pressure is mainly caused by the small or even stop flow of the refrigerant in the refrigeration system. The exhaust pressure is too low, although the phenomenon is manifested at the high pressure end, but the cause is mostly caused by the low pressure end. Common reasons for low exhaust pressure: 1) T...

The Reason Why the Temperature of Condensers of Water Cooled Chillers are Abnormally High
2019-06-28
Why are the temperature of condensers of water cooled chiller are abnormally high? The water-cooled condenser we mention here is mainly used in water-cooled chillers. Its function is to use the high-temperature refrigerant vapor condenser discharged from the compressor as a liquid refrigerant, which is an important part of the refrigeration system to release heat to the surrounding envir...
