Refrigeration figures
On the basis of the 1994 industry energy analysis for supermarkets, etc., Super Køl and COWI have developed a unit termed equivalent metre.
1 equivalent refrigeration metre equals 3,000 kWh/year.
The figures stated have been calculated on the basis of actual measurements previously made, but are in no way “scientific” and should be taken with some uncertainty.
In theory, it is now possible to compute the expected refrigeration need using the following equivalent rates:

Example:
Annual theoretical energy consumption of one milk room:
0.8 equivalent metres * 6 doors * 3000 kWh/year = 14,400 kWh a year
