1、 American National Standard Energy, Performance and Capacity of Household Refrigerators, Refrigerator-Freezers and Freezers ANSI/AHAM HRF-1-2004 (Revision of ANSI/AHAM HRF-1-2002) i PREFACE The Association of Home Appliance Manufacturers develops standards in accordance with AHAMs “Policy and Proced
2、ures Governing Technical Standards“ which states: “AHAM Standards shall be in the best interest, mutually, of consumers who use appliances, the industries which provide and service appliances, and other interested parties. They shall relate to actual use conditions and be technically and scientifica
3、lly sound.” Use or observance of AHAM standards is voluntary. AHAM standards are presented to the American National Standards Institute (ANSI) for recognition as American National Standards. This edition of this standard was approved by ANSI on July 7, 2004, and is currently published as ANSI/AHAM H
4、RF-1-2004. This edition superseded ANSI/AHAM HRF-1-2002. This standard contains test procedures that may be applied to any brand or model of household electric refrigerator, refrigerator-freezer or freezer for measuring performance. Results of tests in accordance with this standard may be publicly s
5、tated. With regard to safety, AHAM recommends that all appliance products-both major and portable-manufactured or marketed in the United States be submitted to an appropriate independent laboratory for inspection and listing in conformance with the safety standards and procedures followed by such la
6、boratories. The relevant standard for refrigerators, refrigerator-freezers and freezers is ANSI/UL 250/CSA C22.2 No. 63 “Standard for Safety, Household Refrigerators and Freezers“. AHAM welcomes comments and suggestions regarding this standard. Any standard may be reviewed and improved as needed. Al
7、l standards must be updated or reconfirmed at least every five years. Any interested party, at any time, may request a change in an AHAM standard. Such request should be addressed to AHAMs President, and should be accompanied by a statement of reason for the request and a suggested alternate proposa

DEFINITIONS 3.1 Household Refrigerator. A cabinet or any part of a cabinet which is designed for the refrigerated stor
27、age of food at temperatures above 32F (0C), which has a source of refrigeration and which is intended for household use. It may include a compartment for the freezing and storage of ice and/or for storage of food at temperatures below 32F (0C). 3.1.1 Basic Refrigerator. A refrigerator which includes
28、 a low temperature compartment for the freezing and storage of ice and intended for short-term storage of food at temperatures below 32F (0C) and normally above 8F (-13.3C). It is characterized by a refrigerated surface(s) that partially encloses the low temperature compartment and cools the fresh f
29、ood compartment by natural convection. It frequently has a partition (called the chiller or drip tray) which when removed or adjusted exposes an additional area of the refrigerated surface to the fresh food compartment. 3.1.1.1 Class I. A basic refrigerator with a low temperature frozen food storage
30、 compartment greater than 0.5 cubic feet in volume capable of maintaining temperatures at or below 15F (-9.4C). 3.1.1.2 Class II. A basic refrigerator with a low temperature compartment greater than 0.5 cubic feet in volume capable of maintaining temperatures below 32F (0C) and normally above 15F (-
31、9.4C) 3.1.2 All-Refrigerator. A refrigerator which does not include a compartment for the storage of food at temperatures below 32F (0C). It may include a compartment of 0.5 cu. ft. (14.2 L) or less for freezing and storage of ice. 3.1.3 Combination Refrigerator-Freezer. A cabinet which consists of
32、two or more compartments, with at least one of the compartments designed for the refrigerated storage of foods at temperatures above 32F (0C) and with at least one of the compartments designed for the freezing and storage of frozen foods at temperatures of 8F (-13.3C) average or below, and typically
33、 capable of being adjusted by the user to a temperature of 0F (-17.8C) or below. 3.2 Household Freezer. A cabinet which is designed for the extended storage of frozen food at an average temperature of 0F (-17.8C) or below and with inherent capability for freezing of food, which has a source of refri
34、geration, and which is intended for household use. 3.2.1 Chest Type. A household freezer which is accessible from the top. 3.2.2 Upright (Vertical) Type. A household freezer which is accessible from the front. 3.3 Household Wine Chiller. A cabinet designed exclusively for the cooling and storage of
35、wine. 3.4 Defrost System. A means to remove frost and/or ice from the refrigerated surfaces. Types of defrost systems that apply to household refrigerators and household freezers are: 3.4.1 Manual Defrost. Manual defrost is one in which defrosting of the refrigerated surface is accomplished by natur
36、al or manual means with manual initiation and manual termination of the overall defrost operation. 3 3.4.2 Semi-Automatic Defrost. A system in which the defrost cycle is manually initiated and automatically terminated, with automatic resumption of normal refrigeration at the conclusion of the defros
37、t operation. Defrost water is disposed of automatically or collected in a container for subsequent manual removal. A means of accelerating the rate of defrost may or may not be included in the product design. 3.4.3 Automatic Defrost (No-Frost). A system in which the defrost cycle is automatically in
38、itiated and terminated, with resumption of normal refrigeration at the conclusion of the defrost operation. The system automatically prevents the permanent formation of frost on all refrigerated surfaces. Nominal refrigerated food temperatures are maintained during operation of the automatic defrost
39、 system(s). The defrost water is disposed of automatically. 3.4.4 Partial Automatic (Cycle) Defrost (Household Refrigerators). A system in which the refrigerated surfaces of the freezer compartment are defrosted manually and the refrigerated surfaces of the fresh food compartment are defrosted autom
40、atically. Defrost water from the fresh food compartment is disposed of automatically or collected in a container for subsequent manual removal. 3.5 Air Ducts. Passages which direct the flow of air. 3.6 Automatic Icemaker. A device, connected to a water supply, which automatically produces, harvests,
41、 and stores ice in a storage bin, with means to automatically interrupt the harvesting operation when the bin is filled to a pre-determined amount. 3.6.1 Cyclic Type. An automatic icemaker with separate and sequential water fill, freezing and harvesting phases of the ice-making operation. 3.6.2 Non-
42、Cyclic (Continuous) Type. An automatic icemaker with simultaneous water supply, freezing and/or harvesting phases in the ice-making operation. 3.6.3 Ice Storage Bin Rating. The capacity of an automatic icemaker storage bin is the average weight of ice contained in the bin when the bin-fill device te

A door that is hinged on the left-hand side when viewed facing the cabinet. 4 3.10.3 Door Dike. A projection on the door which extends into th
46、e refrigerated compartment(s) and which functions primarily as a barrier to minimize heat flow to the interior of the cabinet. 3.11 Fan Shroud. A protective housing which surrounds the fan and which may also direct the flow of air. 3.12 Ice Tray. A container for freezing water into ice. 3.12.1 Autom
47、atic Fill Ice Tray. A tray which is automatically filled with water for freezing into ice. 3.12.2 Ice Tray Capacity Rating.
