How to solve the problem of chiller high pressure caused by hot weather
Recently, due to the high temperature, chillers frequently have high-pressure alarms. I am here to explain to the customers of the chillers how to solve the high-pressure alarm of chillers.
First of all, why the high pressure alarm?
The high pressure alarm is a protection alarm for the chiller itself. How the chiller does not have good heat dissipation (condenser outlet/wind temperature is too high), the unit protection will start the chiller cannot run.
How to solve the problem of chiller high pressure alarm?
In principle, it is possible to improve the cooling of the chiller.
1. If it is an air-cooled chiller, it may be due to prolonged use, the surface of the fin condenser is covered with dust (or the ambient temperature is too high [absorption temperature exceeds 35°]), causing poor heat dissipation. At this time only need to Clean the condenser surface dust (need to improve the ventilation conditions, reduce the ambient temperature) can be.
2. If it is a water-cooled chiller, it may be caused by fouling of the inner copper tube wall of the condenser. Then use the condenser after cleaning
