杭州市城镇住宅太阳能一体化利用潜力分析

Analysis of Integrated Utilization Potential of Solar Energy of Urban Residences of Hangzhou City

本文以杭州市的典型城镇住宅为例,进行太阳能建筑一体化设计分析。本文首先通过调研确定杭州市典型城镇住宅形式,其次对典型住宅的光伏系统和光热系统各可利用部位和系统形式进行分析,最后对光伏和光热系统的各种组合方式下的产能潜力进行了分析。研究结果表明:对杭州典型住宅而言,建筑屋顶和阳台充分利用太阳能的基础上可优先考虑南墙面的太阳能利用;若建筑本体充分利用太阳能,光伏系统发电量可达到16 kW·h/m^(2)以上,光热系统产热量可达到10 kW·h/m^(2)以上。

Taking a typical urban residence in Hangzhou as an example,the integrated design of solar energy buildings was analyzed.This paper first investigated the typical urban residential form in Hangzhou,and then analyzed the installable areas and forms of the photovoltaic and photothermal systems in typical buildings.Finally,the combination modes of photovoltaic and photothermal systems were generated and their solar energy output was calculated.The research results show that for the typical urban residence in Hangzhou,solar energy utilization on the south wall can be given priority on the basis of making full use of the roof and balcony.If the solar energy on the typical residence was fully utilized,the annual electricity production of the photovoltaic system can reach over 16 kW·h/m^(2)and the heat production of the photothermal system can reach over 10 kW·h/m^(2).
