摘要
通过对我国既有建筑能耗现状及节能潜力的分析,提出在不改变既有建筑冷源原有冷水机组的前提下,将冷源改造成蓄冷空调系统,以缓解用电峰谷差大的问题。建立了系统改造优化设计的数学模型以寻找改造后经济最优的蓄冷率。并结合实例,应用模型找到了最佳改造方案,验证了系统改造的经济性及可行性。
Analyses the energy consumption and energy efficiency potential of existing buildings in China.To alleviate the electricity peak-valley difference,proposes transforming the cold source into that with cool storage without changing the water chiller for the existing buildings.Establishes the optimal design mathematical model to find the most economic cool storage rate,obtains the best transformation plan for an example building with the model,and verifies its economical efficiency and feasibility.
