Closed cooling tower is a very important industrial equipment used to reduce temperature in the fields of chemical, electric power, metallurgy and pharmaceutical. They achieve cooling effect by transferring hot water to cooling medium. Below are some technical parameters of closed cooling towers, as well as some guiding significance of their practical application.
1. Cooling tower flow: Flow refers to the water flow through the cooling tower per unit time. The size of the flow determines the quality of the cooling effect. Generally speaking, the larger the flow, the better the cooling effect. Therefore, when choosing a cooling tower, it is necessary to determine the appropriate flow range according to actual needs.
2. Cooling tower inlet and outlet temperature difference: The larger the inlet and outlet temperature difference, the better the cooling effect. This is because the water temperature entering the cooling tower is higher, while the water temperature leaving the cooling tower is lower. Therefore, when designing and operating the cooling tower, the inlet and outlet temperature difference should be increased as much as possible.
3. Cooling tower efficiency: Cooling tower efficiency refers to the ratio between the actual cooling capacity of the cooling tower and the theoretical cooling capacity. It reflects the operating efficiency of the cooling tower. Improving the efficiency of the cooling tower can reduce energy consumption and reduce operating costs.
4. Cooling tower material: Cooling towers are generally made of plastic, metal and other materials. Cooling towers of different materials are suitable for different processes and media. Plastic cooling towers have the characteristics of good corrosion resistance and light weight, and are suitable for cooling corrosive media. Metal cooling towers are suitable for high temperature and high pressure conditions.
5. Cooling tower cooling medium: Common cooling media include air and water. Air cooling towers mainly use air to directly cool the cooling tower, which is suitable for arid areas or places with scarce water resources. Water cooling towers use water to cool the cooling medium and reduce the temperature through heat exchange between the cooling medium and hot water.
6. Cooling tower air volume: Cooling tower air volume refers to the flow rate of air through the cooling tower. The size of the air volume directly affects the cooling effect of the cooling tower. Generally speaking, the larger the air volume, the better the cooling effect. Therefore, when choosing a cooling tower, it is necessary to determine the appropriate air volume range according to actual needs.
