摘要
为了降低西北新农村建筑采暖的能耗,改善室内生活环境,通过试验研究了太阳能主动供暖和传统小型燃煤锅炉供暖的西北新农村建筑的室内热环境、空气质量和采暖能耗的差异。研究结果表明:在室外环境最低温度为-16.2℃条件下,太阳能主动供暖建筑室内平均温度和平均辐射温度分别高出对比建筑5.4℃和3.3℃;在天气晴朗情况下,当室外环境的平均温度高于4.2℃且室外环境的最低温度高于-1.6℃时,仅利用太阳能进行供暖即可满足西北新农村建筑的供暖需求;太阳能主动供暖建筑室内CO,NO2,SO2,CO2及可吸入颗粒物PM10的浓度分别是对比建筑的0.45倍、0.48倍、0.56倍、0.59倍和0.5倍;经过分析得到太阳能主动供暖时室内环境温度与散热片内热水温度以及室外环境温度的二元线性关系;太阳能主动供暖的节能率为86.6%。
To provide technical support for improvement of indoor living environment and the practice of reducing building energy consumption in new rural construction,an active solar water heating system coupled with mini coal-fire boiler is presented in this paper. Comparatively experimental study on indoor thermal environment,indoor air quality and energy consumption of the new rural residence with external wall insulation by 60 mm extruded polystyrene（XPS） outfitted with active solar heating system and a reference residence without external wall insulation heated by traditional mini coal-fire boiler has been conducted in Minqin Gansu. The results show that the indoor average temperature and the mean radiant temperature of the building heated by active solar water heating system are higher than that of building heated only by mini coal-fire boiler by 5.4 ℃ and 3.3 ℃ respectively under the condition that the outdoor minimum temperature is-16.2 ℃. The amount of CO,NO2,SO2,CO2 and PM10in the building heated by active solar water heating system is 0.45 times,0.48 times,0.56 times,0.59 times and 0.5 times of counterparts in the building heated by mini coal-fire boiler respectively. The relation of indoor temperature,inlet water temperature of radiator and outdoor temperature is formulated under some postulates. The energy saving rate of active solar heating is 86.6%.
