Abstract
A test method for determining the efficiency of supermarket
refrigeration systems has been developed. The test method is based
on a combination of measurements of air temperatures and energy
consumption on an actual system and calculations of the energy
consumption for a reference refrigeration system. The reference
system is identical to the actual system regarding type, number
and size of components but the component efficiencies and cooling
demands are assumed to be equal to market average values.The
energy efficiency of the system is expressed by a “Goodness
Number” defined as the ratio between the calculated energy
consumption of the reference system and the measured energy
consumption for the actual system. Four different Danish
supermarkets have been tested using this method. The results show
that supermarkets in Denmark can be expected to have “Goodness
numbers” ranging from 0.42 to 0.75 depending on the type and age
of the refrigeration system.
