摘要
近零能耗建筑遵循“被动优先,主动优化”的原则,良好的被动式建筑设计极大的降低了建筑的能耗需求,而暖通空调系统的优化设计是实现近零能耗建筑低运行能耗的关键。本文以寒冷地区某近零能耗办公楼为例,聚焦其暖通空调系统,利用TRNSYS软件对不同配置下暖通空调系统运行情况进行仿真模拟,研究不同配置下暖通空调系统运行特性,为系统设计提供意见和建议。应用多目标优化配置方法,对不同配置下暖通空调系统全寿命期经济性和运行碳排放进行分析。
Considering that nearly zero energy building design follows the principle of“passive priority,active optimization”,good passive building design greatly reduces the energy demand of the building.However,the optimal configuration of HVAC system is the key to achieving low energy consumption of nearly zero energy buildings.This paper takes a nearly zero energy office building in cold region as an example,and explores its HVAC system.Different configurations of its HVAC system are simulated by using TRNSYS.The operating characteristics of HVAC system under different configurations are studied to provide comments and suggestions for system design.Configuration method of multi-objective optimization is applied to analyze the life cycle costs and the operational carbon emissions under different configurations.
