Simulation analysis of chiller type selection in high efficiency refrigeration room
LIU Tiening
Abstract：In order to explore the factors affecting the selection of chiller in high efficiency refrigeration room,a hotel project in Shanghai was taken as the research object,and the annual energy consumption distribution was analyzed by load calculation and energy consumption simulation software,and a variety of unit selection schemes were developed based on the characteristics of different centrifugal chiller units.The model of high efficiency refrigeration room was built by computer room energy consumption simulation software,and the annual energy consumption and the economy of the whole life cycle of each scheme were compared and analyzed,and the influence of the combination and proportion of different types of centrifugal chiller on the selection of high efficiency refrigeration room chiller was discussed.The results show that the same type of unit selection scheme has certain advantages in the overall energy saving of the system.The maglev unit has the advantages of high energy efficiency ratio and low maintenance cost.The higher its proportion in the unit configuration,the better the economy of the whole life cycle of the system.
