两种太阳能地板采暖系统室内热湿环境的对比实验研究

在两个房间分别安装太阳能空气集热地板出风采暖系统和太阳能低温热水地板辐射采暖系统,并在竖直方向布置温湿度测点,启动系统记录实验数据,分析比较了两套系统下室内温度梯度与相对湿度。得出两套系统下的室内热湿环境优势与不足。空气式地暖白天室内温度上升较快但在夜晚衰减幅度也较大,需借助辅助采暖设备才能满足采暖需求;热水地暖蓄热相对较好,全天均能基本满足采暖需求。

Comparative Experimental Study on Thermal and Humid Environment of Two Types of Solar Floor Heating System

Two types of floor heating system are installed respectively in two similar rooms,one is solar low-temperature heat-water floor heating system,and the other is solar energy air heat-collecting floor heating system,laying out measuring points of temperature and humidity in vertical direction of both rooms.By analyzing and comparing the experimental data on indoor temperature gradient and relative humidity,it can derive advantages and disadvantages of indoor thermal and humid environment under these two types of solar floor heating system.Indoor temperature of air heat-collecting floor heating system can rise to a proper point in a short time in daylight,but it also dropped quickly at night,so auxiliary heating equipment is quite necessary to ensure a comfortable indoor environment.While the thermal storage effect of heat-water floor heating system is comparatively favorable,and can satisfy the heating demand day and night.
