1、 p 1 AHAM RAC-1-WORKING DRAFT - VERSION 1.0 Room Air Conditioners ANSI/AHAM RAC-1-2015 p i ANSI/AHAM RAC-1-2015 PREFACE The Association of Home Appliance Manufacturers develops standards in accordance with AHAMs “Policy and Procedures Governing Technical Standards“ which states: “AHAM Standards shal

2、l 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, be technically and scientifically sound.“ Use or observance of AHAM standards is voluntary. This standa

3、rd contains Test procedures that may be applied to any brand or model of room air conditioner. Results of tests in accordance with this standard may be publicly stated. Recommended levels of performance which are considered important to include but which, necessarily, are recommendations only. AHAM

4、standards are presented to the American National Standards Institute (ANSI) for recognition as American National Standards. This standard was so recognized on May 13, 2015 and bears the American National Standard designation ANSI/AHAM RAC-1-2015. The test results may be compared with AHAMs recommend

5、ed level of performance, if any, for a particular product characteristic. 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 such as Underwriters Laboratories,

6、Inc., or the American Gas Association Laboratories, Inc., for inspection and listing in conformance with the safety standards and procedures followed by such laboratories. The relevant standards for room air conditioners are UL 484, Room Air Conditioners, and this standard, AHAM RAC-1, Room Air Cond

7、itioners. AHAM welcomes comments and suggestions regarding this standard. Any standard may be reviewed and improved as needed. All 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 a

8、ddressed to AHAMs President, and should be accompanied by a statement of reason for the request and a suggested alternate proposal. When metric units are not specified, conversion from customary units should be done in accordance with the American Society of Heating, Refrigerating and Air-Conditioni

PURPOSE This standard establishes a uniform, repeatable procedure or standard method for measuring specified p

17、roduct characteristics of room air conditioners. The standard methods and the recommended levels of performance, where they appear, are intended to provide a means to compare and evaluate different brands and models of room air conditioners regarding characteristics significant to product use. The s

18、tandard methods and the recommended levels of performance are not intended to preclude the exercise of ingenuity or to prevent improvement and innovation in design and performance. 2. SCOPE This standard establishes standard methods for measuring performance and includes sections on definitions, tes

19、t conditions, tests for standard measurements, performance tests, and safety which apply to room air conditioners as defined in 3.1. Performance tests for Heating-Cooling Units (Section 7) apply to units designed as air-to- air source heat pumps with or without supplementary electric resistance heat

20、. The tests do not apply to units with electric resistance as the only heat source. 3. DEFINITIONS 3.1. Room Air Conditioner A room air conditioner is an encased assembly designed as a unit to be mounted in a window or through a wall, or as a console. It is designed primarily to provide free deliver

21、y of conditioned air to an enclosed space, room or zone. It includes a prime source of refrigeration for cooling and dehumidification and means for circulating and cleaning air, and may also include means for ventilating and heating. A packaged terminal air conditioner, a system designed to accommod

22、ate various components for heating methods (steam, electric, hot water, etc.) is not considered a room air conditioner. 3.2. Cooling Capacity Cooling capacity is a measure of the ability of a unit to remove heat from an enclosed space, room or zone. 3.3. Moisture Removal Capacity Moisture removal ca

23、pacity is a measure of the ability of a unit to remove moisture from an enclosed space, room or zone. 3.4. Heating Capacity Heating capacity is a measure of the ability of a unit to add heat to an enclosed space, room or zone. p 2 ANSI/AHAM RAC-1-2015 3.5. Recirculated Air Recirculated air is the ai

24、r discharged by a unit into an enclosed space, room or zone when all ventilating and exhaust dampers are closed. 3.6. Ventilating Air Ventilating air is the air introduced from outside by a unit into an enclosed space, room or zone. 3.7. Exhaust Air Exhaust air is the air discharged to the outside b

25、y a unit from an enclosed space, room or zone. 3.8. Standard Air Standard air is air having a density of 0.075 lb/ft3(1.20 kg/m3) and is equivalent to dry air at a temperature of 70F (21.1C) and barometric pressure of 29.92 inches (101.325 kPa) of mercury. 3.9. Energy Efficiency Ratio The energy eff

26、iciency ratio (EER) is a value representing the relative electrical efficiency of a room air conditioner. It is expressed in Btu/Wh and is obtained by dividing the measured cooling capacity in Btu/h by the measured average electrical power input in watts during the cooling capacity determination. 3.

27、10. Active mode A mode in which the room air conditioner is connected to a mains power source, has been activated and is performing the main function of cooling or heating the conditioned space, or circulating air through activation of its fan or blower, with or without energizing active air-cleanin

28、g components or devices such as ultraviolet (UV) radiation, electrostatic filters, ozone generators, or other air-cleaning devices. 3.11. Inactive mode A standby mode that facilitates the activation of active mode by remote switch (including remote control) or internal sensor or which provides conti

29、nuous status display. 3.12. Off mode A mode in which a room air conditioner is connected to a mains power source and is not providing any active or standby mode function and where the mode may persist for an indefinite time. An indicator that only shows the user that the product is in the off positi

30、on is included within the classification of an off mode. p 3 ANSI/AHAM RAC-1-2015 3.13. Standby mode Any product modes where the energy using product is connected to a mains power source and offers one or more of the following user oriented or protective functions which may persist for an indefinite

31、 time: a) To facilitate the activation of other modes (including activation or deactivation of active mode) by remote switch (including remote control), internal sensor, or timer. b) Continuous functions, including information or status displays (including clocks) or sensor-based functions. A timer

32、is a continuous clock function (which may or may not be associated with a display) that provides regular scheduled tasks (e.g., switching) and that operates on a continuous basis. 3.14. Rounding When this test procedure calls for rounding off of test results, and the results fall equally between two

33、 values of the nearest dollar, kilowatt-hour, or other specified nearest value, the result shall be rounded up to the nearest higher value. 4. TESTING CONDITIONS 4.1.
