摘要
针对大型装配式冷库的施工特点、难点和关键技术,采用围护结构保温设计,在施工过程中运用高效节能多层装配式冷库墙体保温板、隔汽屋面、超平地面及防潮隔汽冷桥处理等安装施工技术,确保工程质量。经模拟计算,常规构造冷库全年冷负荷计算值为4 903 k W·h/m2,本项目冷库全年冷负荷计算值为4 413 k W·h/m2,相比常规冷库,本项目的节能率为9.99%。现今,建设节能型冷库已成为冷库行业的发展方向,本项目所采用的装配式冷库保温设计和安装施工方法及技术对于建设节能型冷库工程具有一定的参考价值。
Considering the features and difficulties during the construction of large assembled cold storage, the envelope insulation design and targeted installation and construction technologies, including, energy-efficient multilayer fabricated cold wall insulation board, vapor barrier roofing, super flat surface and moisture and vapor proof cold bridge, are employed to ensure the quality of the project introduced in this paper. The results of our simulation show that the calculated cold load of this storage is 4 413 kW .h/m2 with the energy saving rate 9.99% when compared with that of conventional constructed cold storages as 4 903 kW. h/m2. The thermal insulation design and installation/construction methods adopted in this cold storage project can provide reference for emerging energy-saving assembled cold storage.
