Application of Dual Cold Source Tem-perature and Humidity Separate Con-trol System in an Office Building Proj-ect in Shanghai
First of all,a new energy saving and low carbon air conditioning cold source technology-dual 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 theoreti-cally 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 sys-tem,dual cold source low temperature fixed frequency+medium temperature system,and dual cold source low temperature frequency conversion+medium temperature system.The annual comprehen-sive energy efficiency value EER of the chiller room is compared with the annual load.Data compari-son 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 invest-ment has a better energy saving effect.
