复合式露点间接蒸发冷却空调机组在敦煌机场某食堂的应用
|
摘要
介绍复合式露点间接蒸发冷却空调机组在敦煌机场某食堂的应用情况,并进行测试分析。结果表明,在室外平均干/湿球温度为30℃/17.7℃,机组进风干/湿球温度为25℃/14℃时,风量为10 000 m~3/h的机组出风干球温度为13℃,温降近15℃,机组平均湿球效率为110%;风量为20 000 m~3/h的机组出风干球温度为17℃,温降仅8℃,机组平均湿球效率为70%。建议适当提高机组的二/一次风量比,以提高机组的效率。
The application of a compound dew point indirect evaporative cooling airconditioning unit to a dinning hall of Dunhuang Airport is introduced and analyzed by tests.The results show that when the outdoor dry and wet bulb temperature are 30℃ and 17.7℃ respectively,and the inlet dry and wet bulb temperatures of the air-conditioning unit are 25℃ and 14℃ respectively,for the unit with air volume of 10 000 m~3/h,its outlet temperature is 13℃,temperature drop is nearly 15 ℃,and average wet bulb efficiency is 110%;for the unit with air volume of 20 000 m~3/h,its outlet temperature is 17℃,temperature drop is only 8℃,and average wet bulb efficiency is 70%.It's proposed that the secondary and primary air volume ratio of unit should be increased,so as to improve the efficiency of unit.
