循环冷却水系统是各工业甚至民用高档建筑能耗的大户,年耗电量约30亿kWh,其节能效果对工业企业的节能影响甚大。冷却塔是循环冷却水系统的关键设备,可以通过降低冷却塔的供水扬程,提高冷却塔的热效率实现节能,也可通过对在役老化的冷却塔的改造实现节能。 Circulating cooling water system is a large household energy consumption of various industries or even civil high-end buildings, the annual power consumption of about 3 billion kWh, its energy saving effect on industrial enterprises have a great impact on energy conservation. Cooling towers are key equipment in recirculating cooling water systems that can save energy by reducing the head of the cooling tower, increasing the thermal efficiency of the cooling tower, and saving energy by retrofitting cooling towers in service.
