摘　　要：建立了蓄冷式中央空调系统分析模型,计算了蓄冷式空调系统和常规空调系统的火用效率,分析了蓄冷式空调系统的薄弱环节和改进方法.蓄冷式空调系统的薄弱环节在于熔冰过程的损失过大,降低熔冰过程的供回水温度和优化换热器的设计可以提高其效率.中央空调系统采用蓄冷方式运行,不仅具有良好的经济效益,而且也具有较高的火用效率.A model of the exergetic analysis of a chill storage-based central air conditioning system is established. In order to compare the above system with a normal one, the exergetic efficiencies of both systems are calculated. The weakness of this system lies in the significant exergetic loss during the ice-melting process. We find that lowering the temperature of supply and return water during the ice-melting process and optimizing the design of heat exchanger can improve the exergetic efficiency. A central air conditioning system run by chill storage features has both economic benefit and high exergetic efficiency.
