The components of the air-conditioning system can transfer the heat in the pipe to the air near the pipe in a quick way. In the distillation process, the device that converts gas or vapor into liquid is called a condenser. All condensers are operated by taking away the heat of the gas or vapor.
The normal operation of the condenser can avoid premature wear of components and maintain the best working condition. The following is a detailed introduction to the troubleshooting of the condenser.
How to troubleshoot the condenser?
1. The condensing temperature is too high (condensing temperature: refers to the condensation temperature of the refrigerant in the condenser) elimination method:
① Insufficient amount of cooling water: The high-temperature gas discharged from the compressor cannot be effectively cooled, which will increase the condensing temperature. A sufficient amount of water should be added.
②The temperature of the cooling water is too high: the high-temperature gas discharged from the compressor cannot conduct heat exchange well, which will increase the condensing temperature. Therefore, appropriate cooling measures should be taken for the cooling water.
③The low vacuum and dryness of the refrigeration system increase the condensing temperature. The solution: increase the vacuum of the system.
2. The condensing temperature is too low:
①The amount of refrigerant in the system is insufficient: sufficient refrigerant should be added according to the instructions.
②The cooling water temperature is too low or the water flow is too large: it should be adjusted appropriately according to the cooling capacity and temperature difference.
3. Too much scale on the condenser:
The scale formed in the condenser is mainly 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 degree of hardness. After the formation of scale, the water flow resistance increases and the heat exchange efficiency decreases, resulting in an increase in the condensation temperature, a decrease in 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. 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 seawater from corroding pipelines and equipment, and adhesion or blockage of aquatic organisms and plants in seawater to pipelines and equipment.
