The normal operation of AIR COOLED CONDENSER can avoid premature wear of components and maintain the best working condition. The following is a detailed introduction to the troubleshooting of AIR COOLED CONDENSER.
How to troubleshoot AIR COOLED CONDENSER?
1. The condensing temperature is too high (condensing temperature: refers to the condensation temperature of the refrigerant in the condenser) Remedy method:
①Insufficient cooling water: the high-temperature gas discharged from the compressor cannot effectively cool down, so that the condensing temperature rises, and sufficient water should be added.
②The temperature of the cooling water is too high: the high-temperature gas discharged from the compressor cannot perform heat exchange well, which increases the condensing temperature. Therefore, appropriate cooling measures should be taken for the cooling water.
③The vacuum degree and dryness of the refrigeration system are low, which increases the condensation temperature. Solution: The vacuum degree of the system should be increased.
2. The condensation temperature of AIR COOLED CONDENSER is too low:
①The amount of refrigerant in the system is insufficient: you should add enough refrigerant according to the instructions.
②The cooling water temperature is too low or the water flow is too large: it should be adjusted according to the cooling capacity and temperature difference.
3, AIR COOLED CONDENSER too much scale:
The scale in the AIR COOLED CONDENSER is mainly caused by the bicarbonate, sulfate and chloride, silica and other impurities that contain a large amount of Ca, Ma, Na elements in the cooling water. The existence of these substances makes the water have a certain Hardness, after the formation of scale, the water flow resistance increases, the heat exchange efficiency decreases, resulting in an increase in the condensation temperature, a decrease in the refrigeration capacity, and an increase in power consumption. In severe cases, the pipe wall will be eroded.
In order to prevent such accidents, clean water should be used, and if the water quality does not meet the requirements, chemical water treatment should be used. If the cooling water is seawater, measures should be taken in the design to prevent the corrosion of seawater to pipes and equipment and the adhesion or clogging of pipes and equipment by aquatic organisms and plants in seawater.
