摘　　要：介绍双冷源温湿度独立控制空调系统,并对该系统的高低温冷源负担的负荷进行分析。分析表明:该空调系统中高低温冷源负荷主要取决于第一机器露点。因此,进一步分析该系统的第一机器露点发现:机组能耗均随着第一机器露点的右移而减小,即高温机组冷冻水温度越高,系统越节能。该研究为空调系统的节能设计奠定了坚实的理论基础。Temperature and humidity independent control air-conditioning system with dual-cold-source is introduced, the cold source loads at low and high temperature are ana- lyzed. The results show that the cold source loads at low and high temperature are mainly decided by the first machine dew point. Furthermore,it is found out that the system＇s en- ergy consumption declines when first maehine dew point moving toward right position, which means that the ehilled water temperature higher,the system＇s energy consumption lower. The research establishes a firmly thesis base for the energy-saving design of air-con- ditioning system.
