431.64—Uniform test method for the measurement of energy consumption of commercial refrigerators, freezers, and refrigerator-freezers.
(a) Scope.
This section provides the test procedures for measuring, pursuant to EPCA, the daily energy consumption in kilowatt hours per day (kWh/day) for a given product category and volume or total display area of commercial refrigerators, freezers, and refrigerator-freezers.
(b) Testing and calculations.
(1)
Determine the daily energy consumption of each covered commercial refrigerator, freezer, or refrigerator-freezer by conducting the test procedure set forth in the Air-Conditioning and Refrigeration Institute (ARI) Standard 1200-2006, “Performance Rating of Commercial Refrigerated Display Merchandisers and Storage Cabinets,” section 3, “Definitions,” section 4, “Test Requirements,” and section 7, “Symbols and Subscripts.” (Incorporated by reference, see § 431.63) For each commercial refrigerator, freezer, or refrigerator-freezer with a self-contained condensing unit, also use ARI Standard 1200-2006, section 6, “Rating Requirements for Self-contained Commercial Refrigerated Display Merchandisers and Storage Cabinets.” (Incorporated by reference, see § 431.63) For each commercial refrigerator, freezer, or refrigerator-freezer with a remote condensing unit, also use ARI Standard 1200-2006, section 5, “Rating Requirements for Remote Commercial Refrigerated Display Merchandisers and Storage Cabinets.” (Incorporated by reference, see § 431.63 )
(2)
Conduct the testing required in paragraphs (b)(1) of this section, and determine the daily energy consumption, at the applicable integrated average temperature in the following table. The integrated average temperature is determined using the required test method.
| Category | Test procedure | Integrated average temperatures |
|---|---|---|
| (i) Refrigerator with Solid Door(s) | ARI Standard 1200-2006* | 38 °F (±2 °F). |
| (ii) Refrigerator with Transparent Door(s) | ARI Standard 1200-2006* | 38 °F (±2 °F). |
| (iii) Freezer with Solid Door(s) | ARI Standard 1200-2006* | 0 °F (±2 °F). |
| (iv) Freezer with Transparent Door(s) | ARI Standard 1200-2006* | 0 °F (±2 °F). |
| (v) Refrigerator-Freezer with Solid Door(s) | ARI Standard 1200-2006* | 38 °F (±2 °F) for refrigerator compartment.0 °F (±2 °F) for freezer compartment. |
| (vi) Commercial Refrigerator with a Self-Contained Condensing Unit Designed for Pull-Down Temperature Applications and Transparent Doors | ARI Standard 1200-2006* | 38 °F (±2 °F). |
| (vii) Ice-Cream Freezer | ARI Standard 1200-2006* | −15.0 °F (±2 °F). |
| (viii) Commercial Refrigerator, Freezer, and Refrigerator-Freezer with a Self-Contained Condensing Unit and without Doors | ARI Standard 1200-2006* | (A) For low temperature applications, the integrated average temperature of all test package averages shall be 0 °F (±2 °F).(B) For medium temperature applications, the integrated average temperature of all test package averages shall be 38.0 °F (±2 °F). |
| (ix) Commercial Refrigerator, Freezer, and Refrigerator-Freezer with a Remote Condensing Unit | ARI Standard 1200-2006* | (A) For low temperature applications, the integrated average temperature of all test package averages shall be 0 °F (±2 °F).(B) For medium temperature applications, the integrated average temperature of all test package averages shall be 38.0 °F (±2 °F). |
