When the high and low temperature integrated machine is running, the system prompts that the high pressure operation is usually due to:
If the cooling water flow is too low or the water temperature is too high, it is necessary to increase the cooling water flow or reduce the water temperature.
The copper tube of the condenser has a lot of scaling, and the heat exchange effect is poor, so the heat exchanger needs to be cleaned.
If there is too much refrigerant, it is necessary to discharge some refrigerant to the outside. If the opening of the refrigerant is too small, it is necessary to adjust the opening of the expansion valve.
