Summary

The energy consumed by domestic refrigerated appliances can be a significant proportion of household energy use. If refrigerated appliances use excessive energy there may be valid technical reasons to replace high energy using appliances with more efficient ones. This paper assesses the definition of an over consuming appliance by examining data from a large scale survey of energy consumption and internal temperature in 998 cold appliances. Monitored cold appliances were classified according to compressor run time (which has been reported in a literature example as being a metric to identify over consuming appliances). The method provided a ‘rough estimate’ of over consumption but does incorrectly categorise some appliances as over-consuming as no account is taken of temperature control within an appliance. Temperature effects had minimal impact on the over consumption category but had a significant impact on energy consumed. It was found that if appliance temperature could be adjusted that significant energy and money could be saved.
