摘　　要：通过对西安某高校食堂的建筑热环境以及围护结构情况进行实地调研,结合节能、环保、经济的蒸发冷却技术,采用直接蒸发冷却设备——蒸发式冷气机为该食堂进行通风降温设计;同时,选取柜式空调作为备选方案,通过对比两种方案,发现采取蒸发冷却空调方案的能耗是柜式空调的69.7%,其节能效果显著,在经济性层面,分别就初投资以及年运行费用来比较,蒸发式冷气机系统也较好;为验证其降温效果,分别采集其运行时温度和相对湿度,并进行分析,结果表明蒸发式冷气机降温效果较明显,对蒸发式冷气机方案的设计以及选择有好的借鉴意义。This paper conductes a field investigation on the building thermal environment and envelope structure of a college canteen in Xi’an,combining energy-saving,environmentally friendly,and economical evaporative cooling technology,and uses direct evaporative cooling equipment-evaporative air conditioners to ventilate and cool the canteen;At the same time,the cabinet air conditioner is selected as an alternative.By comparing the two options,it is found that the energy consumption of the evaporative cooling air conditioner is 69.7% of that of the cabinet air conditioner,and its energy saving effect was significant.In terms of economy,the initial investment and annual operating cost,the evaporative air-conditioner system is also better;In order to verify its cooling effect,the temperature and relative humidity during the operation are collected and analyzed.The results show that the evaporative air-conditioner has a more obvious cooling effect.The design and selection of the machine program has a good reference.
