AHAM welcomes comments and suggestions regarding this standard.
The set of complete cycles shall include the last complete compressor motor cycle during the test period. This document shall not be reproduced in whole or in part by any means, and shall not be transmitted electronically or otherwise to a third person without the prior written permission of AHAM. Temperature measuring devices shall be located rhf shielded so that indicated temperatures are not affected by the operation of the condensing unit or adjacent ahwm.
The volume of the evaporator space see Section 4. Proceed to Checkout Continue Shopping. The average per-cycle energy consumption for a cycle type is expressed ahwm kWh per cycle to the nearest one hundredth 0. The purpose of this standard is to establish a uniform and repeatable procedure or standard method for measuring specified product characteristics of household refrigerators, household wine chillers and household freezers.
The two-part test method in Section 5. It bypasses the thermostat control and operates continually until the feature is terminated either manually or automatically.
Testing shall be performed in accordance with one of the following sections using hrt appropriate standardized reference temperatures: Temperatures shall be recorded as in Section 5.
AHAM HRF-1: Household Refrigerators, Combination Refrigerator-Freezers, and Household Freezers
An automatic icemaker with separate and sequential water fill, freezing and harvesting phases of the ice-making operation. The same unit shall be used for both parts of the test. If the compartment volume is less than 2 cubic feet, then a single thermocouple shall be located at the geometric center of the compartment. Ice trays Section 3. Temperatures shall be recorded at three or five locations as shown by Figure ahaam Weight shall be determined by use of scales accurate to within 0.
It is not intended to provide a means of measuring the food-storage capacity. They shall relate to actual use conditions and be technically and ahm sound. The average per-cycle energy consumption for a cycle type Section 3.
The cooling of hf icemaker area s shall remain unchanged. A means of accelerating the rate of defrost may or may not be included in the product design.
For through the door ice and water dispensers, the ice chute will be included in the volume up to the dispensing function. A combination of components from the various figures may be used for other designs.
See Section 4 3. If the document is revised or amended, you will be notified by email. Prior to the initiation of the door-opening sequence, the refrigerator defrost control mechanism may be re- initiated in order to minimize the test duration. A projection on the door which extends into the refrigerated compartment s and which functions primarily as a barrier to minimize heat flow to the interior of the cabinet. This standard is also available to be included in Standards Subscriptions.
The test is repeated on at least one more unit of the model and until the Mean Time Between Defrosts for the multiple unit tests MTBD2 satisfies the statistical relationship.
Packages shall rest on the bottom of the liner or on top of a trivet if furnished. Stabilization is defined as a minimum of three consecutive defrost cycles with times between defrosts that will allow the calculation of a Mean Time Between Defrosts MTBD1 that satisfies the statistical relationship of 90 percent confidence.
If the model being tested has a variable defrost control Section 3. An external drawer that is designed to pull or tip out. You may delete a document from your Alert Profile at any time. If the time between defrosts is greater than 96 hours compressor “on” time and this defrost period can be repeated on a second unit, the test may be terminated at 96 hours CT and the absolute time value used for MTBD for each unit.

For types 5 and 6; the height dimension shall be measured hrr the bottom of the liner or from the top of a trivet, if furnished. The system automatically prevents the permanent formation of frost on all refrigerated surfaces. Analog Watt-hour meters shall be graduated in intervals no greater than 0.
The “run-in” may be made at any convenient room temperature. The recorded temperature of the freezer compartment shall be the average of the temperatures recorded at the locations shown in Figure The depth dimension shall be measured from the back of the liner to a plane defining the gasket sealing surface.
Basic refrigerator 39F 3. A system in which the defrost cycle is automatically initiated and terminated, with resumption of normal refrigeration at the conclusion of the defrost operation. The cabinet with its refrigerating mechanism shall be assembled and set up as nearly as practical in accordance with the printed instructions supplied with the cabinet. All deducts are the same. A tray which is automatically filled with water for freezing into ice.
The volume of air ducts required for proper cooling and operation of the unit. Such request should be addressed to AHAM’s President, and should be accompanied by a statement of reason for the request 20008 a suggested alternate proposal. For type 5; non-refrigerated shelves are treated as if they were not there.
