摘要:

基于EnergyPlus能耗模拟软件,通过理论分析与建模数据比较,对大型空调系统末端简化进行了研究。分析研究了空调末端风机模型,明确了风机能耗与风机风量的关系。针对定风量和变风量系统提出了3种准确度不同的简化方法,建模者可以根据建模目的选择相应的方法。验证了简化方法在典型办公建筑中的应用。

Abstract:

Based on EnergyPlus energy consumption simulation software, studies the terminal simplification of a large air conditioning system by theoretical analysis and modeling data comparison. Studies the fan models of air conditioning terminal, and finds the relationship between fan energy consumption and air flow. Presents three simplified methods applied to different CAV and VAV systems, which can be chosen by users according to their objectives. Verifies the simplified method application to typical office buildings.
