摘　　要：为了在东北等严寒地区利用太阳能实现清洁供暖,以沈阳市辽中区绿色农房体验中心项目为例进行研究.该建筑采用太阳能热水地板辐射采暖系统采暖.对比研究其室内热环境﹑采暖系统运行效果和系统经济性,得出的研究结果表明:在两部分共26 d的连续测试期间,采用太阳能主动﹑被动结合采暖系统下的主要房间温度稳定在18~21℃,只有9 d室内最低温度低于18℃,但最低温度高于16℃;在三段连续的5 d不同室外温度工况下,室温仍稳定在16.5~21.5℃;虽然采暖系统耗电量增加,但室温波动情况证实了采暖系统的可行性﹑节能性和经济性,即太阳能热水地板采暖系统在采暖季可充分满足建筑物在不同室外温度条件下的建筑采暖需求.研究结果可用来指导太阳能采暖系统在严寒地区的推广和应用.In order to realize clean heating by using solar energy in severe cold areas such as northeast China,a green farm house experience center project in Liaozhong district of Shenyang city is analyzed.The solar hot water floor radiation heating system is utilized,the indoor thermal environment,heating system running effect and cost are expounded comparatively,research results show that,during the continuous testing of two parts-26 days totally,the main room temperature is stable at 18~21℃ under the solar active and passive combined heating system,the minimum temperatureindoor is lower than 18℃ for nine days,which is higher than 16℃,the lowest temperature demand.Under differentoutdoor temperature conditions,the room temperature is still stable at 16.5~21.5℃in three consecutive five-day period.Although the power consumption of the heating system increases,the fluctuation of room temperature proves the feasibility,energy efficiency and economy of the heating system.Thesolar hot water floor radiation heating systemcan fully meet the building heating needsunder different outdoor temperature conditionsduring the heating season.The research results can be used to guide the promotion and application of solar heating systems in severe cold regions.
