摘　　要：本文分析了冷源系统的构成和节能途径,依据按需供冷的控制新方法,采用美国奥莱斯公司的控制模块库,编制了简明实用的冷源群控节能管理程序。着重研究了按冷需求优化设定冷冻水供水温度、冷机群控管理和按冷需求对冷冻水泵变频控制。通过实验平台的测试验证了程序的可行性和稳定性,并在实际工程应用中取得了很好的效果。Analyzed the composition and the energy saving ways of the chiller plants system. Programmed the applicable chiller plant control energy saving management programs, based on the new method of cooling on demand and the graphic function blocks of American ALC Corporation.The chilled water supply temperature reset optimization program, the chiller operating numbers control pro-gram, the chillers’starting in proper order control program,the chillers management program and chilled pump frequency conversion control program are included. The feasibility and stability was tested and verified in the laboratory. The ideal effect was also achieved in the practical project.
