针对南疆地区农宅冬季无集中供暖、采暖能耗大的问题,提出一种太阳能联合生物质能的主被动结合式供暖系统。为分析被动式改造及主被动结合式供暖系统对室内热环境的影响,以南疆地区一栋农宅为研究对象,对其进行被动式改造并安装主动式采暖设备后开展试验研究。结果表明：相较于普通农宅,对试验房进行围护结构保温节能改造后,室内平均温度提高11.77 ℃;在保温节能改造的基础上将南向墙体改造为集热蓄热墙,可提高室内平均温度2.84 ℃;供暖中期及末期,试验房采用被动式太阳房采暖结合主动式设备供暖的采暖方式,在供暖中期,主动式部分提供93%的热量,被动式部分仅提供7%的热量;供暖末期,主动式部分提供80%的热量,被动式部分提供20%的热量。此外,在采用主被动结合式供暖时,试验房温度高于18 ℃,达到寒冷地区冬季供暖室内设计温度要求。
Abstract
In response to the problem of the lack of central heating in the winter and the high energy consumption for heating in the farmhouses in southern Xinjiang, an active-passive combined heating system of solar energy combined with biomass was proposed. In order to analyze the effects of passive renovation and combination of active and passive heating on the indoor thermal environment, a farmhouse in the southern Xinjiang area was selected for the study, and an experimental study was carried out after passive renovation and installation of active heating equipment. The results show that after the energy-saving renovation of the building envelope of the test house, the average indoor temperature increased by 11.77 °C compared to the normal farm house. Converting the south wall into heat-collecting storage wall on the basis of insulation and energy-saving renovation, which can increase the average indoor temperature by 2.84 ℃. The test house was heated by passive solar room heating combined with active equipment in the middle and at the end of the heating period. In the middle of the heating period, the active part provided 93% of the heat and the passive part provided only 7% of the heat. At the end of the heating period, the active part provided 80% of the heat and the passive part provided 20%. In addition, with the combination of active and passive heating, the test room temperature was above 18 ℃. This met the interior design temperature requirements for heating in cold regions in winter.
