为确定影响寒区太阳能技术应用的关键因素,利用问卷调查法对哈尔滨30多个小区80位太阳能设备用户进行实地访谈,统计了被访者对屋顶太阳能设备能效、运行情况、设备成本、耗电量、屋顶结构损坏、视觉污染度、安装方便性、易跌落度和防冻性9项指标的评价.认为成本较高的占70%,存在视觉污染的占82.5%,设备防冻性差的占66.25%.这3项是当前影响寒区太阳能技术应用最迫切的关键因素(>50%).针对上述问题,分析了屋顶集成设计需解决的主要技术问题和应对措施,并指出需借用多目标函数法进行数理统计达到多目标优化,从建筑学、结构工程和工业设计等跨学科领域联合进行太阳能屋顶集成设计.
To determine the key factors affecting the application of solar energy technology in cold regions, a questionnaire survey was conducted to interview 80 solar energy users in more than 30 communities in Harbin. The questionnaires were used to survey the energy efficiency, operation status, equipment cost and electricity consumption of rooftop solar energy equipment Quantity, roof structure damage, visual pollution degree, ease of installation, easy drop and frost resistance evaluation of the nine indicators that the higher cost of 70%, visual pollution accounted for 82.5%, poor antifreeze equipment accounted for 66.25% These three items are the most critical factors (> 50%) that affect the application of solar energy technology in cold regions at present.According to the above problems, the main technical problems and countermeasures to be solved in roof integrated design are analyzed, and the multi-objective function method Mathematical statistics to achieve multi-objective optimization, from the architectural, structural engineering and industrial design and other interdisciplinary field of solar roof integrated design.
