            摘要:

            3個應用集中式空調系統的實際居住建筑工程為例,對集中式空調系統在居住建筑中的適用性進行分析和討論,探討實際居住建筑中造成集中式空調和分散式空調應用效果差異的關鍵因素,并說明各自的適用條件。研究表明在我國居住建筑中,用戶側的負荷具有需求不同步、負荷率低的特征,當應用集中式空調系統時,在用戶末端或水系統的可調性受限的情況下,系統容易產生高能耗或低能效的問題。

            關鍵詞:居住建筑,集中式空調系統,分散式空調,能耗對比,適用性分析

            Abstract:

            Taking three real residential building projects with centralized air conditioning systems as examples, analyses and discusses the practicability of centralized air conditioning systems in residential buildings. Investigates key factors that lead to the differences between centralized and distributed air conditioning systems in residential buildings, and gives practicable conditions of the two kinds of systems respectively. The research result proves that, in residential buildings in China, because of the load features of non-synchronized demand and low load rate in user side, the problems of high energy consumption or low energy efficiency would happen when applying the centralized air conditioning system with limited regulating ability in user end or water system.
