为了研究长江流域建筑的除湿量,本文首先简述了长江流域的热湿环境,并以上海为代表计算了单位人员的年除湿量分布,从而得到了上海地区不降温除湿和空调除湿的分界线;而后,研究了在不同人员密度下的办公建筑和住宅建筑的显热、潜热负荷比例,说明不同的热湿负荷比适用于不同的除湿方式,从而为不同类型建筑的除湿方式选取提供依据。
In order to study the dehumidification capacity of buildings in the Yangtze River basin, this paper first briefly describes the hot and humid environment in the Yangtze River basin. Using Shanghai as a representative, we calculate the annual dehumidification capacity per unit of personnel, and get the demarcation line of dehumidification and air conditioning dehumidification in Shanghai After that, the sensible heat load and latent heat load of office buildings and residential buildings under different occupant densities were studied. The results showed that different heat and moisture load ratios were applicable to different dehumidification methods, which provided the basis for selecting different types of dehumidification methods.
