Why is there a situation where the high pressure of the industrial chiller is too high, and how should we deal with this situation? Next, let's take a look at the reasons and solutions for the excessive pressure of industrial chillers.
To solve the problem that the pressure relay often trips, it is necessary to find the reason for the high pressure of the industrial chiller. The reasons are generally as follows:
1. Excessive charging of refrigerant
2. There is air in the refrigeration system
3. The refrigeration system pipeline is blocked
4. Poor heat dissipation of the condenser
5. The cooling water temperature is too high
For the reasons mentioned above, I carefully summarized it. During the use of industrial chillers, because of water quality problems, the condenser needs to be cleaned frequently to avoid clogging. The water in the cooling tower should be replaced frequently, and the cooling tower should also be frequently replaced. For cleaning, the cooling water tower placed on the building should be ventilated. These are the most obvious and the most common problems.
1. For water-cooled chillers, due to the lack of water or insufficient water in the condenser, or the temperature of the inlet water is too high, the compressor discharge pressure may be too high and a high pressure alarm may occur;
2. For air-cooled industrial chillers, poor heat dissipation from the condenser, non-condensable gas in the system, and partial blockage of the refrigeration pipeline may cause excessive condensing pressure and high-pressure alarms. For chillers, high pressure refers to compressor discharge pressure.
