Optimising energy use in refrigeration systems

Abstract

The energy used to operate a refrigeration system accounts for a significant proportion of the total lifetime cost of ownership of the system and yet surveys show huge variation in the amount of energy required from one system to another. This paper considers ways in which energy is used and reasons why there is such a large discrepancy in usage between systems. It describes recent work to assess and benchmark the performance of cold storage facilities and explains a methodology for ensuring that cold and chill stores operate as efficiently as possible.
