Cooling systems and refrigerators are widely used for condensers in petrochemical field, air-condition systems in semiconductor factories, humidistat in textile factories. Furthermore, large wholesale stores, exhibition centers, and large hospitals use lots of large centrifugal water chillers frequently because of the air-condition load is between 1,000 to 10,000 RT. Therefore, the ice storage systems are used in many cases to decrease the load during peak hours. The majorities of large water chillers are centrifugal; usually parallel water chillers are used at the same time for the air-condition systems. This paper is going to talk about the experiment on the highly running centrifugal water chiller. Usually we only consider about the efficiency under the full load when selecting a water chiller. Actually, the water chiller runs with partially load most of the time. The purpose of this research is to find out the most efficient way of running the water chiller, and learn how the energy got consumed while the water chiller runs partially. Eventually, combine the water chiller with ice storage system and efficient running formula for saving energy.
