AHAM HRF-1-2019 – Energy and Internal Volume of Refrigeration Products has been released. This revised standard is intended to establish a uniform procedure for measuring specified product characteristics of refrigerators and related compressor-driven appliances.
Specifically, AHAM HRF-1-2019 applies to refrigerators (including “all-refrigerators” and “refrigerator-freezers”), freezers, and wine chillers. The distinction between these types is important for the tests, as the standard calls for different guidelines to carry out the procedures. For example, temperature control settings should be performed in accordance to the following standardized reference temperatures: 39°F (3.9°C) for all-refrigerators, refrigerators, and refrigerator freezers, 0°F (-17.8°C) for freezers, and 55°F (12.8°C) for wine chillers.
The first of the three procedures covered in AHAM HRF-1-2019 is that for determining the total refrigerated volume of the appliance, including the different compartments of the refrigerator, freezer, etc. This is not intended to provide a means of measuring the food-storage capacity of the appliance, but for assisting the other procedures covered by the document.
The second procedure is meant to establish a shared method for measuring electrical energy consumption at various control settings. This, in turn, provides a standard procedure for determining energy consumption of refrigerators, freezers, refrigerator freezers, and wine chillers. For this methodology, AHAM HRF-1-2019 details intricate guidelines for the placement and handling of different refrigerator parts that should be followed for its compliance.
Since it is intended to calculate the energy specifications of appliances for consumer use, the energy test method should simulate typical room conditions both with and without door openings. This allows the test appliance to operate in manner equivalent to ambient conditions.
The third procedure is for computing the adjusted volume of refrigerator appliances, and it is to be used to compare the relative energy efficiency between different products.
AHAM HRF-1-2019 – Energy and Internal Volume of Refrigeration Products is now available on the ANSI Webstore.
