中央空调系统节能探讨

On Energy Saving of Central Air Conditioning System

简要分析了当前我国节能形势的严峻性,提出了商用空调节能的必要性,从分析冷水机组效率提高的可行性方案入手,提出了系统节能的概念,引入了大温差和一次泵变流量系统(VPF)的概念,通过理论性论述和实际案例的对比,对两种系统的可行性作简单分析,并分别对两种系统的特点提出见解。

The situation of energy saving is analyzed in brief in China, which indicates that energy saving of air conditioning system is necessary and urgent. Based on the analysis of the feasible project to increase the efficiency of chiller, the concept of energy saving of air conditioning system and the ideas of great temperature difference and variable primary flow system are introduced in the paper. On the basis of theoretical analysis and comparison of practical cases, the feasibility and traits of the two systems are analyzed briefly in the paper.
