If the ahan has the quick freeze option, it shall be used ahham bypass the temperature control. The volume agam air ducts required for proper cooling and operation of the unit. Chiller or drip trays shall be in their proper places during all tests. If the interior arrangements of the freezer compartment shelves do not conform with those shown in Figuremeasurements shall be taken at locations selected to represent the intent of the standard.

A control scheme that changes the defrost interval from a fixed length to an extended length without any intermediate steps is not considered a variable defrost control. The recorded temperature at any given point during a cycle of operation with the temperature being read at regular intervals not exceeding 4 minutes. The cooling of the icemaker area s shall remain unchanged.

Therefore, the times between defrost should vary with different usage patterns and include ahzm continuum of lengths of time between defrosts as inputs vary. The packages shall be sealed and shall contain a liner or wrapper that makes them moisture and vapor-proof. No freezer temperature measurements need be taken in an all-refrigerator model.

For types 5 and 6; the height dimension shall be measured from the bottom of the liner or from the top of a trivet, if furnished. The recorded temperature of the freezer compartment shall be the average of the temperatures recorded at the locations shown in Figure The complete liner comprises the compartment liner in the cabinet, the exposed breaker strip surfaces and the door liner s. All deducts are the same. A first part shall be the same as the test for a unit having non-automatic defrost see Section 5.

If the compartment temperature s measured during these two tests bound the appropriate standardized temperature sthen these test results shall be used to determine energy consumption for a given setting of the anti-sweat heater switch.

If the interior arrangements of the cabinet do not conform with those shown in Figuremeasurements shall be taken at selected locations chosen to approximately represent the entire freezer compartment Section 3. 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.

Need more than one copy? For refrigerators and refrigerator-freezers: When testing for energy consumption, this is considered a manual defrost product. If the model being tested has a long-time automatic defrost system, the test period may consist of two parts: The system automatically prevents the permanent formation of frost on all refrigerated surfaces. Also, the product shall not recover differently during the defrost recovery period than it would in typical room conditions.

One which essentially fills the interior cross-section of the cabinet. The temperature measurements shall be made with one or more of the following instruments or their equivalents.

For demand defrost models with no values for CTL and CTM in the algorithm, the default values of 6 and 96, respectively, shall be used. Subscription pricing is determined by: The items below shall be considered as being in place and their volumes deducted: The total volume shall be the sum of the volumes of all compartments and be recorded to the nearest 0.

If the model being tested has a variable defrost control Section 3. One which is less than either the width or the depth, or both, of the full shelf. All components not explicitly associated with the harvesting of ice must be operative during the energy test and shall be energized in a manner consistent with the duty cycle necessary to perform the respective functions.

The first freezer door-opening shall be simultaneous with the fourth fresh food door-opening.
