摘　　要：辐射空调在夏热冬冷地区住宅建筑中应用时面临着的除湿能力不足、易结露等弊端可以采用独立的新风除湿系统来有效解决。为了实现住宅建筑室内除湿任务,本文在对全年热湿负荷特点分析的基础上,将除湿季节划分为三种运行模式:夏季模式、过渡季节A模式、过渡季节B模式,同时结合3种除湿模式下的温湿度特点,提出了相应的除湿运行方式。通过实验对运行效果进行测试,实验结果表明,出风干湿球温度在不同运行模式下基本稳定,出风含湿量可以满足除湿需求。Regarding the drawbacks of insufficient dehumidification capacity and tendency to condensation of the radiant air-conditioning system in residential buildings of hot-summer and cold-winter region,it is feasible to adopt an independent fresh air dehumidifier to solve the problems effectively. In order to realize dehumidification for the indoor environment of residential buildings,this paper analyzes the characteristics of thermal load and humidity load around the whole year, and proposes three kinds of dehumidification patterns for the seasons that require dehumidification,namely,summer pattern for high temperature and high humidity,pattern A for transition season of normal temperature and high humidity,as well as pattern B for transition season of low temperature and high humidity. Besides,the paper puts forward corresponding operation strategies for the three patterns,and conducts experimental studies for the operation strategies. The research results show that the air-out dry and wet bulb temperature is basically stable in different operation patterns,and the air-out moisture content can satisfy the dehumidification demand.
