摘　　要：首先对一种节能低碳的新型空调冷源技术——双冷源温湿度分控系统进行简要介绍,随后结合压焓图与焓湿图对双冷源温湿度分控系统的节能原理进行理论分析。再结合上海某办公建筑项目实际工程,分为单冷源系统、双冷源低温定频+中温系统以及双冷源低温变频+中温系统三个方案对冷水机房全年综合能效值EER与全年负荷进行数据对比分析,进一步验证双冷源温湿度分控系统能够显著提升冷水机房全年综合能效值以及双冷源系统低温侧采用初投资较低的定频机组节能效果更佳的结论。First of all,a new energy saving and low carbon air conditioning cold source technologydual cold source temperature and humidity separate control system is briefly introduced.Then,the energy saving principle of the dual cold source temperature and humidity separate control system is theoretically analyzed combined with the enthalpy map and enthalpy humidity map.Combined with the actual project of an office building project in Shanghai,it is divided into three schemes:single cold source system,dual cold source low temperature fixed frequency+medium temperature system,and dual cold source low temperature frequency conversion+medium temperature system.The annual comprehensive energy efficiency value EER of the chiller room is compared with the annual load.Data comparison and analysis further verified that the dual cold source temperature and humidity control system can significantly improve the annual comprehensive energy efficiency value of the chiller room and the low temperature side of the dual cold source system adopts fixed-frequency units with lower initial investment has a better energy saving effect.
