窗式直接蒸发冷却器在干燥地区居住建筑的应用研究

Application research of window-type direct evaporative cooler in residential buildings in dry areas

为了对室内空气降温的同时增加大量新风的补充,采用直流式全新风模式的蒸发冷却空调给室内降温。对使用窗式直接蒸发冷却器降温的新疆乌鲁木齐市天山区某住宅房间送风温湿度进行测试,数据表明,进风口温度在29℃,出风口温度为22℃,湿球效率为72%,室内温度稳定在25℃,相对湿度为59%,温湿度满足舒适性要求。

The place where people stay for the longest time in life is usually residential buildings, whose indoor air quality is closely related to our health, so it is very important to deal with the indoor environment of residential buildings. In order to add a large number of fresh air to the cooling of indoor air, we use the evaporative cooling air conditioning with direct current fresh air mode to cool the indoor air. The project tests the air supply temperature and humidity of a residential room in Tianshan District of Urumqi City, Xinjiang, which uses window-type direct evaporative cooler to cool down. The data show that the air inlet temperature is 29 ℃, the air outlet temperature is 22 ℃, the wet bulb efficiency is 72%, the indoor temperature is stable at 25 ℃, the relative humidity is 59%, and the temperature and humidity meet the comfort requirements.
