It has advantages of both air cooling and evaporative cooling in heat exchange. Dry running and wet running can be provided at the same time. It is suitable for closed industrial circulating water cooling system, especially in arid or water-deficient areas. It can be used in industries like metallurgy, iron and steel, electricity, chemicals, coal chemicals, textiles (chemical fiber, printing and dyeing), pharmaceutical, paper making and polycrystalline silicon.
It is suitable for closed industrial circulating water cooling system, especially in arid or water-deficient areas. It can be used in industries like metallurgy, iron and steel, electricity, chemicals, coal chemicals, textiles (chemical fiber, printing and dyeing), pharmaceutical, paper making and polycrystalline silicon.
It keeps advantages of the existing closed cooling system - "three non-pollution" and "two savings".
It has advantages of both air cooling (without water deprivation) and evaporative cooling (little water deprivation and low temperature at cooling water outlet) in heat exchange.
It resolves the problem that air cooling system cannot meet the requirement in summer and evaporative cooling system consumes a lot of water.
Air cooling system and evaporative cooling system play their respective functions in different seasons and different sections of heat exchange and cooperate with each other in cooling.
Its control model is intelligent control. It can save water and energy, so it is economically feasible.
It can offer cooling function in dry running under high temperature and 60-90% of water can be saved.
It uses the integrated technologies of aerodynamics, thermodynamics, fluidics, materials science, static and dynamic structural mechanics, intelligent control and processing technology.
It has advantages of both air cooling and evaporative cooling in heat exchange. Dry running and wet running can be provided at the same time. If the temperature is higher than the designed temperature to cut off water supply, evaporative cooling is the principal part for heat exchange and air cooling is the assistant part, and so most of thermal load is borne by evaporative cooling. If the temperature is lower than the designed temperature to cut off water supply, air cooling is the principal part for heat exchange and evaporative cooling is the assistant part, and so most of thermal load is borne by air cooling. Therefore, the goal of water saving, energy saving and operating expense saving in circulating water cooling process can be realized.
