摘要
以西北地区新农村住宅为研究对象,试验研究冬季太阳能地板采暖和散热器采暖室内热环境,现场测量室内温度、湿度、风速、PM_(10)、PM_(2.5)、SO_2气体等指标,结果表明:地板采暖较散热器采暖具有更高的太阳能利用率,地板采暖具有更好的室内风环境和室内湿环境,室内更加卫生,2种采暖末端装置室内平均辐射温度均随着供暖的进行呈现先升后降的趋势,地板采暖室内平均辐射温度下降较散热器采暖平均辐射温度下降存在时间上延迟的优势,地板采暖室内温度分布更加均匀,舒适性更高。
Taking the new rural house in northwest China as the research object,the experimental study is conductedduring winter on indoor thermal environment of solar floor heating and radiator heating,indicators such as indoortemperature,humidity,wind speed,PM_(10),PM_(2.5),SO_2 were measured by field test.The results show that compared withradiator heating,floor heating has a higher utilization of solar energy,better Indoor air and humidity environment,andmore hygienic.Both of the two end heating devices have the same change trend of firstly increased and then decreased.Compared with the radiator heating,the decrease of the mean radiant temperature for floor heating has the advantage oftiming delay.The indoor temperature distribution of floor heating is more uniform and more comfortable.
