摘　　要：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。Aiming at the situation of low energy utilization and poor indoor air quality in winter of traditional buildings of northwestern villages and small towns,original heating by boiler was replaced to mainly by solar hot water system for indoor heating in winter and for households＇ domestic hot water.Indoor air quality of the individual building with solar energy hot water system in northwest villages and small towns was tested.Results show that,average value contents of SO_2,NO_2,CO of one hour,average value contents of TVOC of eight hours,daily maximum value contents of CO_2 and PM_（10）,indoor air velocity and air relative humidity are all in line with the GB/T 18883—2002＂Indoor air quality standard＂.At the same time,average indoor temperature is in line with the GB/T 50824—2013＂Design standard for energy efficiency of rural residential buildings＂.Then indoor air quality of individual building in northwest villages and small towns is evaluated by using the comprehensive index,it is concluded that indoor air quality rating of the building is level Ⅱ,air quality evaluation results is no pollution.
