Why do closed cooling towers save money than open cooling towers?
Closed cooling tower and open cooling tower are industrial cooling equipment, but due to the different materials and production processes used by the two, the pre-purchase price of closed cooling tower is more expensive than that of open cooling tower.
Closed cooling tower and open cooling tower are industrial cooling equipment, but due to the different materials and production processes used by the two, the pre-purchase price of closed cooling tower is more expensive than that of open cooling tower.
But why is it that in the long run, the use of closed cooling towers is more economical than the use of open cooling towers?
Today, follow Xiaozhou to learn more about it!
1. Water saving
The circulating water in the closed cooling tower is completely isolated from the air, no evaporation, no consumption, and can automatically switch the operation mode according to the working conditions. In the autumn and winter seasons, only the air cooling mode is required, which not only ensures the cooling effect, but also saves water resources.
The water loss of the closed cooling tower is 0.01, while the water loss of the open cooling tower is 2%. Taking the 100-ton cooling tower as an example, the open cooling tower wastes 1.9 tons of water per hour more than the closed cooling tower, which not only wastes water resources, but also increases the cost of enterprise expenditure. If the machine works 10 hours a day, 1.9 tons of water will be lost in one hour, and 19 tons in 10 hours, the current industrial water consumption is about one ton in 4 yuan, and the water fee in 76 yuan will need to be increased every day. This is only 100 tons of cooling tower, if it is 500 tons, 800 tons of water needs to spend about 300 more per day, a month is about 10000, a year is more than 120000.
Therefore, the use of closed cooling towers, annual water costs can be reduced by about 120000.
2. Power saving
Open cooling tower only air cooling system fan system, closed cooling tower in addition to the air cooling fan system, but also added a spray system. From the initial performance point of view, the open cooling tower is more energy-saving than the closed cooling tower.
According to statistics, equipment scaling every increase of 1mm, system energy consumption increased by 30%, and the closed cooling tower circulating water completely isolated from the air, no scaling, no blockage, stable performance, and open cooling tower circulating water directly in contact with the air, easy to scale blockage,
Therefore, in general, the closed cooling tower is more energy-saving than the open cooling tower!
3. Land saving
The operation of the open cooling tower requires excavation of the pool, and the closed cooling tower does not require excavation of the pool, and the area is small, which is very suitable for enterprises that require the layout of the workshop.
4. Post-maintenance cost
Because the internal circulation of the closed cooling tower is not in contact with the atmosphere, the entire system is not prone to scaling and blockage, the failure rate is low, and it does not require frequent downtime for maintenance.
The circulating water of the open cooling tower is in direct contact with the atmosphere, which is prone to fouling and blockage, and has a high failure rate. It requires frequent downtime for maintenance, which increases maintenance costs and production losses caused by frequent downtime.
5. Operation condition in winter
Closed cooling tower in winter with antifreeze can run as usual, does not affect the production schedule, open cooling tower in order to prevent water freezing, can only be temporarily shut down.
