干燥地区住宅建筑蒸发冷却通风空调技术的应用研究

Application research on evaporative cooling ventilation and air conditioning technology for residential buildings in dry areas

居住建筑是人们在生活中停留时间最久的场所之一,所以给其提供一个较好的空气品质尤为重要。传统的家用空调只能解决室内热湿负荷,不断去处理循环风,人们在室内停留时间过长可能会导致"空调病",为了避免以上情况,我们采用可以补充新风的蒸发冷却空调给室内降温[1]。其中,可应用于住宅建筑的蒸发冷却设备有移动蒸发式冷风扇、窗式直接蒸发冷却器、热回收新风换气机和露点间接蒸发冷却空调,对相关工程进行实测分析,其温湿度均满足舒适性要求。

Residential buildings are one of the places where people stay for the longest time in life,so it is particularly important to provide them with a better air quality.Traditional household air conditioning can only solve the indoor heat and humidity load,and constantly deal with circulating air.People may stay indoors for too long,which may lead to"air conditioning disease".To avoid the above situation,we use evaporative cooling air conditioning which can supplement fresh air to cool the indoor.Among them,the evaporative cooling equipment which can be used in residential buildings are mobile evaporative cooling fan,window direct evaporative cooler,heat recovery fresh air exchanger and dew point indirect evaporative cooling air conditioning.The related projects are tested and analyzed,and the temperature and humidity meet the comfort requirements.
