Large scale cold stores: an innovative design approach

摘要

This paper describes the design details of a dual stage ammonia refrigeration system servicing a large, new commercial cold storage facility in South East Queensland, Australia. Actual key performance data including store temperatures, power consumption and annual energy consumption for the facility are described. Comparisons between a similar existing facility and the new facility both operated by the same owner show a reduction in annual energy consumption per unit volume of cold storage in the new store of more than 30%. The innovative penthouse evaporator concept reduced specific evaporator power consumption to approximately one third of conventional designs operated by the same owner.
