Energy Consumption Evaluation of Water Chiller in Cooling Station

The energy consumption of air conditioning and refrigeration system in public buildings accounts for a large proportion, mainly due to the problem of excessive energy consumption in the operation of chillers in the system. Based on the performance parameters provided by the manufacturer, this paper evaluates the energy consumption of the water-cooled chiller under different load rates in typical days of cooling season, analyzes the coefficient of performance (cop) of the chiller under different load conditions, and discusses several ways to improve the efficiency of the chiller.
