Best-practice energy performance benchmarking for refrigerated warehouses
Jensen will present recorded specific energy consumption values for a range of refrigerated warehouses constructed in Australia from 1999 to 2019. These refrigerated warehouses vary widely in terms of volume, temperature mix, usage, refrigerant choice and refrigeration plant concept.
Jensen will demonstrate that despite the significant spread in specific energy consumption (SEC) values for a number of refrigeration plant concepts, a clear and predictable pattern emerges for one type in particular. He will explain the factors influencing the spread in recorded energy performance values on the basis of practical energy consumption records pertaining to the various plant types, and will show what SEC-values are practically achievable.
He will then propose best-practice energy performance for refrigerated warehouses in Australia. This proposal will be based on actual recorded values for approximately 20 installations completed since 2013 in various Australian jurisdictions. This provides refrigerated warehouse operators with a benchmark to measure actual energy performance against and initiate improvement actions to address inefficiencies.
