During the use of the chiller, failure is inevitable, and it will not cause too much impact if it can be found and solved in time. In many cases, we know the fault through the high and low pressure alarm signal of the chiller. What kind of fault does this represent and how to solve it?
In the case of high pressure, the alarm of the chiller is generally due to poor heat dissipation; if it is in a low pressure state, it may be caused by a lack of refrigerant, which is very unfavorable for all parts of the chiller. Yes, it should be ruled out as soon as possible.
The high and low pressure switches installed on the chiller are for the purpose of alarming, but there are several forms of them. When eliminating the alarm, it is necessary to determine the operation mode of the chiller, the control mode of the panel, and the high and low pressure. points. Only then can targeted solutions, such as cleaning the cooling network, condenser or leak detection, leak repair, adding cold coal, etc. This problem should be resolved soon.
