四级蒸发冷却组合式空调机组能耗分析

【中文摘要】 以西安地区的1台50 000 m3/h风量的四级蒸发冷却机组为例,通过实际测定所获得的各段效率,将有关数据用于该四级蒸发冷却机组的能耗计算与分析,得到了在额定工况下该空调机组的能效比,为蒸发冷却空调机组在西安等中湿度地区的应用提供了参考依据。

【英文摘要】 The four-stage evaporative cooler with 50000 m3/h air volume was taken as an example in Xi'an area.According to the efficien-cy of every paragraph obtained by the actual determination,the relevant data were used in the calculation and analysis on the energy con-sumption of four evaporative cooling units,and energy efficiency ratio of the air conditioning units at the rating condition was obtained,which provides a reference for the application of evaporative cooling air-conditioning unit in the regions of humidity such as Xi'an.
