摘 要: 考虑重庆村镇建筑围护结构特征,现场实测了解不同供水温度工况(35,40,45℃)的毛细管网地板辐射和强风模式下不同设定温度(22,18,26℃)的传统空调供热房间室内温度场的分布情况。对比几种典型供热方式下的室内温度分布特点,结果表明,毛细管地板辐射系统供暖的热舒适性高于空调供暖,垂直温差小于4℃;关机后室内温度衰减缓慢,5 h下降值仅为1~4℃;在同类围护结构性能条件下,供水温度40℃时各平面都能达到室内供暖设计温度最低标准。
关 键 词: 通风与空调工程;毛细管辐射供暖;村镇;现场实测;热舒适性

Abstract: Taking enclosure structure characteristics of Chongqing rural building into account, temperature distributions of indoor heating are learned through the field measurement, whose operation conditions are different water supply temperatures (35, 40, 45℃) of the capillary floor radiant and wind patterns under different set temperatures (22, 18, 26℃) of the traditional air conditioning. A comparison of several typical heating characteristics of the indoor thermal distribution shows that the thermal comfort of capillary floor radiant heating system is higher than air conditioning, whose vertical temperature difference is less than 4℃. Indoor temperature attenuates slowly after shutdown, getting only 1-4℃decline after 5 h. Under the condition of similar enclosure structure performance, every plane can achieve minimum standards for design temperature of indoor heating when the water supply temperature is 40℃.
