Abstract
This paper is based on actual measurement weather data of recent decade in Ji'nan, P.R. China, and profile and characteristics of outdoor air wet bulb temperature are analyzed. It is found that outdoor air wet bulb temperature has an effect on the performance of chillers. Results show that cooling capacity is increased by 9.0 percent, consumption power is reduced by 17.2 percent, and coefficient of performance is stepped-up by 31.5 percent when chillers operate at night.
Last summer, the performance of chillers in a hotel building in Ji'nan was measured. Measurement results showed good agreement with theory calculation results
