摘要
冷水大温差运行方式能够减小冷水流量,从而减小管路管径和水泵能耗,降低系统的初投资和运行费用。但在冷水大温差运行模式下,空调系统的冷源、输配和末端环节的设计匹配与常规系统相比都将产生相应的改变。本文分别从冷源、输配和末端三方面对大温差运行方式的适应性、经济性等作了具体的阐述分析,从而为旧系统的大温差改造或者新系统的大温差方案设计提供一定的理论参考和技术支持。
Chilled water large temperature difference operation can reduce the cold water flow rate, thus reducing the pipe diameter and pump energy consumption, also lowering the system＇s initial investment and running costs. However, with this running mode,the cold source, transmission and terminal part of the air conditioning system should be designed differently from the common ones. In the paper, the adaptability and economy of the system were analysed from these three respects. It can be referenced for the modification of old system and design of the new system.
