What is the reason for the high discharge pressure of the compressor in the water cooled industrial chiller?
1、 Reasons for Excessive Compressor Discharge Pressure
Insufficient refrigerant reflux in the evaporator: When the refrigerant reflux in the evaporator is insufficient, the amount of refrigerant in the evaporator is insufficient to completely evaporate, resulting in low evaporator temperature and high compressor exhaust pressure.
Poor heat dissipation of the condenser: When the condenser has poor heat dissipation, the refrigerant cannot be fully cooled in the condenser, resulting in high refrigerant temperature and high compressor exhaust pressure.
Compressor exhaust temperature too high: When the compressor exhaust temperature is too high, it can cause the compressor exhaust pressure to be too high, which may be caused by compressor wear, excessive refrigerant, condenser pipeline blockage, and other reasons.
2、 How to solve the problem of high exhaust pressure of compressors
Increasing the refrigerant return flow rate of the evaporator: By increasing the refrigerant return flow rate of the evaporator, the amount of refrigerant in the evaporator can be increased, ensuring complete evaporation of the refrigerant in the evaporator and reducing the compressor exhaust pressure.
Cleaning the condenser: Regularly clean the condenser to ensure its surface is clean and capable of sufficient heat dissipation, avoiding poor heat dissipation of the condenser and causing high compressor exhaust pressure.
Check the exhaust temperature of the compressor: Regularly check the exhaust temperature of the compressor. If it is too high, it is necessary to check the wear and tear of the compressor, whether there is too much refrigerant, and whether the condenser pipeline is blocked, and promptly address any issues.
Installing an overheat controller: By installing an overheat controller, the temperature of the condenser can be monitored in real-time. When the temperature of the condenser is too high, the compressor will automatically stop to avoid excessive discharge pressure of the compressor.
Replace the compressor: If the compressor has aged or severely damaged, it may be necessary to replace it with a new one to improve the refrigeration efficiency and stability of the chiller.
