摘要
玻璃温室由于墙体热损失大,造成能耗高,为降低温室能耗.以严寒地区Venlo型玻璃温室为研究对象,提出主动光伏发电和被动围护结构节能改造两种方法来降低温室的能耗.采用能耗、碳减排量和回收期对方案进行比较,通过综合对比选出最优方案.结果表明采用三层玻璃夹气层为9mm氪气的Venlo型光伏温室(CgⅢ)为最优节能改造方案.方案改造下的温室每年可节约130MWh能耗,有助于玻璃温室在严寒地区的推广.
Abstract
Due to the large heat loss of the walls,glass greenhouses often have high energy consumption.Active pho-tovoltaic power generation and passive envelope structure energy-saving retrofit are proposed for the Venlo-type glass greenhouse in severe cold areas.The energy consumption,carbon reduction,and payback period are compared within the two methods for the optimal one.The results show that the Venlo-type PV greenhouse with a three-layer glass and a 9mm krypton gas air layer(CgⅢ)is the best energy-saving retrofit case,which save 130MWh of energy consumption per year,contributing to the promotion of glass greenhouses in severe cold areas.
