【摘要】 以大连地区农村住宅为对象,采用现场实测和问卷调查方式,研究了半吊炕及被动式太阳能集热墙对室内热环境的调节作用,从室内温湿度、炕表面温度及运行方式、人为因素影响等方面对热环境进行了评价。被动式太阳能集热墙与新型节能灶炕耦合运行模式明显好于炕单独作用,虽然前者初投资增加了10%,但每个冬季可节省供暖用煤50%左右。更多还原

【Abstract】 For rural residences in Dalian area, based on field measure and questionnaires, investigates the indoor thermal environment in the coupled heating pattern by the data of indoor temperature and relative humidity, surface temperature and operation mode of kang, and human’s activities, etc. The results show that the effect of the coupled heating pattern is superior to that of single kang pattern, and that the former could save coal for heating by about 50% while its initial investment increases by only 10%.更多还原
