合肥乡村住宅室内热环境分析及改善方案
发布时间：2018-12-13 08:11
【摘要】：为了有效改善合肥乡村夏季室内热环境,先针对室内舒适性进行问卷调查,调查结果显示合肥夏季室内热环境舒适性较差;再利用舒适度仪实地测量合肥夏季室内热环境相关参数,并采用Phoenics对该室内自然对流过程中的空气流场和温度场进行模拟,分析得到夏季室内温湿度及热舒适状况。通过比较实验测量数据和模拟结果,验证了软件分析室内热舒适性的准确性,进而分析了合肥夏季舒适性不佳的主要原因。在此基础上提出改善合肥住宅室内热环境的相关思路,详细分析两种改善方案,分别是从被动方式和主动方式两个不同角度来考虑。被动方式主要采取促进合理的自然通风来降低室内负荷,提高室内热舒适性;主动方式是通过使用空调系统来改善室内热环境,同时利用DeST模拟得出的建筑能耗分析验证地源热泵使用的可行性,从节能的角度为有效改善室内环境提供参考。
[Abstract]:In order to effectively improve the indoor thermal environment in rural areas of Hefei in summer, a questionnaire survey on indoor comfort was carried out, and the results showed that the indoor thermal environment comfort in Hefei in summer was poor. The relative parameters of indoor thermal environment in Hefei in summer were measured by the comfort meter, and the air flow field and temperature field during natural convection were simulated by Phoenics, and the indoor temperature and humidity and thermal comfort in summer were analyzed. The accuracy of software analysis for indoor thermal comfort was verified by comparing the experimental data and simulation results, and the main reasons for the poor summer comfort in Hefei were analyzed. On the basis of this, the paper puts forward the relevant ideas to improve the indoor thermal environment of Hefei residence, and analyzes in detail two kinds of improvement schemes, which are considered from two different angles of passive mode and active mode respectively. The passive way mainly adopts the promotion reasonable natural ventilation to reduce the indoor load, enhances the indoor thermal comfortableness; The active way is to use air conditioning system to improve the indoor thermal environment, at the same time, using DeST simulation analysis of building energy consumption to verify the feasibility of ground-source heat pump use, from the point of view of energy saving to provide a reference for the effective improvement of indoor environment.
