Analysis on energy saving potential of refrigerating system for using air-conditioning

Energy consumption of adjusting projects is calculated when two water chillers and chilled water pumps run in variable flow volume according to the statistic result of air conditioning load in a year and the part-load characteristic of water chillers,and the optimum adjusting project of water chillers and pumps is gained.One water chiller and one water pump run under 50% of load ,whose refrigerating effect and timing ratio change with the variety of load in time.Beyond fifty percent of load,two chillers which provide refrigerating effect equally and two pumps whose timing ratio are same run.The results shows that it can save 23.7% of energy consumption.
