What are the advantages of an open-loop circulating cooling water system?
The advantage of an open-loop circulating cooling water system is that the temperature of the circulating water is lower than the air temperature. The water temperature in an open-loop circulating cooling water system is generally 5-6 degrees lower than the ambient temperature, and it is also affected by the environmental humidity and the wind speed over the fill material. This temperature is called the wet-bulb temperature. When the humidity remains constant, evaporation and condensation reach equilibrium. Condensation releases heat, which is carried away by the air moving from bottom to top; as a result, the temperature of the water from which heat has been absorbed drops below the ambient temperature.
In an open-loop circulating water cooling system, the cooling of water occurs through direct contact with air. Depending on the manner in which water comes into contact with air, it can be classified into surface cooling, spray cooling in pools, and cooling tower cooling, among others. Its advantage is that the temperature of the circulating water is lower than the air temperature, and hard water (such as river water or lake water) can be used for the circulating water
Simple structure, low cost, and easy maintenance and repair~~
Compared to direct-current cooling water, it allows for reduced consumption of cooling water, and the greater the concentration ratio, the more water can be saved.
