How to Adjust the Pressure of Industrial Chiller Condenser?

When the industrial chiller is in long-term operation, once the temperature changes, it will also cause the condensing pressure of the condenser to change, especially when the ambient temperature is relatively high. Once the condensing pressure is relatively high, it is easy to cause the compressor. The power consumption will also increase, which will reduce the cooling capacity, so pay attention to adjust the condensing pressure during use, how to adjust it?

During the operation of the industrial chiller, it is necessary to control the condensing pressure of the condenser. If the condensing pressure is too low, the throttle valve will not have enough power to supply liquid. If the condensing pressure is too high, it will also cause the throttle valve to throttle. reduced flow capacity.

How to adjust the condensing pressure of the condenser? The user can adjust the condensing pressure by adjusting the cooling water flow during the use of the industrial chiller. Adjustment is made by installing a regulating valve on the cooling water outlet pipe of the condenser.

There are two adjustment methods, one is to use the temperature at the cooling water outlet of the condenser to adjust the water volume, which itself contains a temperature sensor package, when the water temperature is high, the valve will be opened larger, and when the water temperature is low, the valve will be closed turn down.

Another adjustment method is to use a pressure-type water volume regulating valve for the condensing pressure, and the pressure signal is drawn out through the condenser. Once the condensing pressure is relatively high, the valve is opened larger, and when the condensing pressure is low, the valve is closed smaller.

The condenser of some industrial chillers has a cooling tower cooling water circulation system. By adjusting the water bypass valve, the problem of low condensing pressure can be avoided. If it is a relatively large industrial chiller, the number of water pumps can be changed to adjust the cooling water flow to change the condenser pressure.
