基于西北村镇传统单体建筑能源利用率低、室内空气质量差的现状,将传统建筑的供能系统改为冬季主要由太阳能热水系统为室内供暖且为住户提供生活热水,并对建筑室内空气质量进行试验测试,测试结果得到:室内SO_2、NO_2、CO含量的1 h平均值,TVOC含量的8 h平均值,CO_2、PM_(10)含量的日平均值、室内风速和室内空气相对湿度在试验周期内都符合GB/T 18883—2002《室内空气质量标准》的相关规定,室内温度平均值在太阳能热水系统供暖期间符合GB/T 50824—2013《农村居住建筑节能设计标准》的相关规定;经综合指数对室内空气质量进行评价,得出太阳能热水系统供能的西北村镇单体建筑空气质量级别属于Ⅱ级,空气质量评价结果为未污染。
Based on the low energy efficiency and poor indoor air quality of the traditional single-building buildings in the northwestern villages and towns, the energy supply system of the traditional buildings was changed to a solar heating system mainly for indoor heating in winter and hot water for domestic residents, Air quality test results, the test results were: indoor SO 2, NO 2, CO content of 1 h average, TVOC content 8 h average, CO 2, PM 10 content of daily average, indoor wind speed and indoor air relative humidity In the test cycle are in line with GB / T 18883-2002 “indoor air quality standards,” the relevant provisions of the average indoor temperature during the solar hot water heating system in line with GB / T 50824-2013 “residential building energy-saving design standards,” the relevant The comprehensive index of the indoor air quality evaluation, concluded that the solar water heating system for energy supply in the northwest of the village single building air quality level is Ⅱ, air quality evaluation results for the non-polluting.
