摘要:

同樣供冷需求下不同冷源方案的運行能耗不同,其主要影響因素為建筑全年空調負荷分布特性。以廈門市某棟公共建筑集中空調系統為例,對比分析了4種不同冷水機組臺數及單機制冷量配置方案,提出了以冷負荷數據分析為基礎的冷源優化配置初選計算方法和模擬計算方法。同時,研究了不同負荷特性與冷源配置之間的規律,分析總結了集中空調系統冷源配置的一般性規律和設計方法。

關鍵詞:集中空調;冷源配置;負荷特性;能耗模擬;節能;設計優化

Abstract:

The study finds that the operating energy consumption of different cold source schemes will be different under the same cooling demand, and the main influencing factor is the annual air conditioning load distribution characteristics of the building. Taking the central air conditioning system of a public building in Xiamen as an example, this paper compares and analyses four different chiller units and single cooling capacity configuration plans, and proposes a calculation method for the primary selection of cold source optimal configuration based on cooling load data analysis. At the same time, the law between different load characteristics and cold source configuration is studied, so as to analyse and summarize the general law and design method of cold source configuration of the central air conditioning system.
