夏热冬冷地区新农宅夏季室内热环境调查及节能改造方案优化设计
|
摘要
为了解当前夏热冬冷地区新农宅的室内热环境现状,根据湖北省当阳市某新农宅调研数据和室内、外温湿度实测结果,分析其室内热环境;结合测试结果,通过正交试验设计和空调能耗模拟手段对影响新农宅能耗的多个因素进行量化分析,提出节能改造措施。实测表明:新农宅夏季室内平均温度为31.5℃,平均湿度为77.4%,且随着楼层越高室内平均温度越高,波动幅度越大,而相对湿度变低,波动幅度变大。能耗模拟表明:考虑节能措施时,应优先考虑新农宅外墙的热工性能,即降低传热系数,其次可考虑提高外窗以及屋顶的热工性能。
To understand the current situation of the indoor thermal environment of new rural houses in hot summer and cold winter regions, the indoor thermal environment was analyzed based on the survey data of a new rural house in Dangyang City, Hubei Province, and the actual indoor and outdoor temperature and humidity measurements; The cross-experimental design and air-conditioning energy consumption simulation methods quantify various factors affecting the energy consumption of new farmhouses and propose energy-saving measures. The measured results show that the average indoor summer temperature of the new farmhouse is 31.5℃, and the average humidity is 77.4%. With higher floors, the higher the average indoor temperature, the greater the fluctuation, and the lower the relative humidity, the larger the fluctuation range. The simulation of energy consumption shows that when considering energy conservation measures, priority should be given to the thermal performance of the exterior walls of new farm houses, thus, to lower the heat transfer coefficient, and secondly, the thermal performance of the outer windows and roofs can be considered.
