基于DEST的近零能耗建筑负荷特性研究——以寒冷地区居住建筑为例

Research on building load characteristics of nearly zero energy building based on DEST——example of residential buildings in cold regions

以寒冷地区居住建筑为例,通过DEST软件建立典型建筑模型,研究近零能耗建筑和不同节能水平下节能建筑的负荷特性,对比不同建筑之间负荷强度和负荷分布差异,分析用户侧冷热需求差异,得出近零能耗建筑空调系统应用建议。

This article taking residential buildings in cold areas as an example, through DEST to establish a typical building model, study the load characteristics of energy-efficient buildings with near-zero energy buildings and different energy-saving levels, compare the differences in load strength and load distribution between different buildings, analyze the difference between users’ cold and heat demand, and obtain near-zero energy buildings. Air conditioning system application recommendations.
