摘要(Abstract):

建立了无填料冷却塔试验平台,研究了不同进风位置、气水比、室外空气干球温度、循环水进水温度下无填料冷却塔冷却性能的变化规律。结果表明:上喷式无填料冷却塔上进风时冷却效率优于下进风,下喷式无填料冷却塔下进风时冷却效率优于上进风;气水比升高冷却效率升高,但气水比达到1.8后,继续提高气水比冷却效率增速降低;室外空气干球温度升高,冷却效率降低;进水温度升高冷却塔冷却效率均得到提高,但上喷式冷却塔冷却效率的提高明显大于下喷式冷却塔。
An experimental system was established for shower cooling tower,the impact of different air inlet position, air drybulb temperature, air-water ratio, inlet water temperature on the thermal efficiency was studied. The results show that for upjet shower cooling tower, the cooling efficiency is higher when air was induced from tower top,for the down-jet shower cooling tower the cooling efficiency is higher when air was induced from tower bottom;the cooling efficiency increased with the airwater ratio increasing, when the ratio increased to1.8, continue to increase the air-water ratio, the efficiency of shower cooling tower increaseslowly;the cooling efficiency reduced with the outdoorair dry-bulb temperature increasing; the cooling efficiency is increased with the inlet water temperature increasing, while the increase of up-jet shower cooling tower is better than down-jet shower cooling tower.
