Energy performance of walk-in freezer and walk-in cooler components

1.1
This Standard applies to walk-in coolers and walk-in freezers (i.e., an enclosed refrigerated storage space that can be walked into) having a total chilled storage area of less than 278.71 m2 (3000 ft2).

1.2
This Standard does not apply to commercial refrigeration appliances covered under CAN/CSA-C657.

1.3
Energy performance evaluation of a walk-in cooler and walk-in freezer is done by evaluating energy performance of the principal components individually that make up a walk-in. This Standard applies to the following walk-in cooler and walk-in freezer components:

a) display doors;
b) non-display doors;
c) non-display panels; and
d) refrigeration systems.
