Cause Of Freezing In Various Parts Of Cooling Tower

Causes of freezing in various parts of cooling towers

In winter when the temperature is relatively low, icing is a normal phenomenon, but if there is icing in the cooling tower, it will cause great harm to its operation. But since the problem already exists, it is necessary to analyze its cause and find ways to avoid it.

Once the cooling tower freezes, not only the tower's ventilation and cooling efficiency will be affected, but in severe cases, the equipment will be damaged. In the entire cooling tower, some parts are relatively easy to freeze, including the air inlet, water spray filler, tower top and fan blades, etc. The specific reasons will be analyzed one by one.
The icing at the air inlet of the cooling tower is mainly caused by the small amount of water around the water spray filler. When a small amount of water flowing down the tower wall stays on the upper edge of the air inlet or the edge of the water retaining eaves for too long, once there is cold air It will freeze over. The reason why a large area of water-sprinkling packing freezes is related to the heat load and water volume of the cooling tower. If these two aspects are too small to meet the standard, ice will hang on the bottom of the water-sprinkling packing.
If the number of cooling towers is large, and some of them are not in operation, then the water vapor discharged from the running towers will fall on the blades of the stopped towers, and ice will naturally form. If these icings are not dealt with, the harm can be imagined, and further research is required in anti-icing.www.gwbrefrigeration.com
