ASHRAE STD 72
Method of Testing Open and Closed Commercial Refrigerators and Freezers
|Publication Date:||31 July 2018|
This standard applies to the following types of open and closed commercial refrigerators and freezers used for displaying or holding products for which refrigeration is either required or desired:
a. Horizontal, semivertical, and vertical open and closed refrigerators and freezers
b. Both remote and self-contained open and closed refrigerators and freezers
This standard does not apply to walk-in coolers or refrigerators and freezers where the refrigerated air is in communication with walk-in coolers.
The purpose of this standard is to prescribe a uniform method of testing open and closed refrigerators and freezers for rating so that comparative evaluations can be made of energy consumption, product temperature performance, refrigeration load, the suction pressures required, and other performance factors.
