Analysis of the role of the cooling tower in the maintenance of the chiller. During the maintenance of the chiller, the maintenance project of the large cooling tower was noticed. This is a good example of the chiller maintenance news, helping more customers to understand our manufacturers. When the cooling tower is being repaired, We should pay attention to the work carried out on the basis of the maintenance of the chiller. This is the cooling tower repair contracted by Zhongshan Kelly.
Let's talk about the role of the cooling tower. This is summarized in the maintenance of the chiller. The company also provides cooling tower installation engineering, which is one of the company's cold water system engineering.
First, the core function of the cooling tower maintenance of the chiller
Main function: The heat exchange mode of water and air in the cooling tower is that the air flowing through the water surface is in direct contact with the water, and the heat in the water is transmitted to the air through contact heat transfer and evaporation, and the cooling method is used. It is called a wet cooling tower.
Second, the heat exchange analysis of the cooling tower of the chiller maintenance
1. The heat exchange efficiency of the wet tower is high. The limit temperature of the water being cooled is the wet bulb temperature of the air. However, the water is lost due to evaporation; the evaporation also increases the salinity of the cooling water according to the circulation. In order to stabilize the water quality, it must be discharged. Part of the water with a higher salinity;
2, the wind will also cause water loss. The loss of these waters must be sufficient to replenish fresh water, so the wet tower needs a source of recharge water;
3. The function of the cooling tower in the chiller is to exchange heat between the cooling water with waste heat and the air in the tower to transfer the waste heat to the air and dissipate the atmosphere.
Third, the chiller maintenance cooling tower in the water shortage area of ​​the role analysis:
1. In the case of water shortage, if there is difficulty in replenishing water; only dry cooling towers (referred to as dry towers or air cooling towers) can be used;
2. The heat exchange efficiency of the dry tower is lower than that of the wet tower, and the limit temperature of the cooling is the dry bulb temperature of the air;
3. Heat exchange between air and water (also air and exhaust steam) in the dry tower; heat is transferred from the surface of the radiator composed of metal tubes to transfer the heat of water or steam in the tube to the air flowing outside the radiator. The chiller product maintenance is the company's long-term business. From the perspective of chiller maintenance, the main function of the cooling tower is that the experienced chiller maintenance factory can make such experience. The company's chiller maintenance business is in many places. It is the core mission of the company to help customers solve problems quickly and effectively.
