5、A 30329www.ashrae.orgSPECIAL NOTEThis American National Standard (ANS) is a national voluntary consensus standard developed under the auspices of the AmericanSociety of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Consensus is defined by the American National StandardsInstitute (A
6、NSI), of which ASHRAE is a member and which has approved this standard as an ANS, as “substantial agreement reached bydirectly and materially affected interest categories. This signifies the concurrence of more than a simple majority, but not necessarily unanimity.Consensus requires that all views a
7、nd objections be considered, and that an effort be made toward their resolution.” Compliance with thisstandard is voluntary until and unless a legal jurisdiction makes compliance mandatory through legislation.ASHRAE obtains consensus through participation of its national and international members, a
8、ssociated societies, and public review.ASHRAE Standards are prepared by a Project Committee appointed specifically for the purpose of writing the Standard. The ProjectCommittee Chair and Vice-Chair must be members of ASHRAE; while other committee members may or may not be ASHRAE members, allmust be
9、technically qualified in the subject area of the Standard. Every effort is made to balance the concerned interests on all ProjectCommittees. The Manager of Standards of ASHRAE should be contacted for:a. interpretation of the contents of this Standard,b. participation in the next review of the Standa
10、rd,c. offering constructive criticism for improving the Standard, ord. permission to reprint portions of the Standard.DISCLAIMERASHRAE uses its best efforts to promulgate Standards and Guidelines for the benefit of the public in light of available information andaccepted industry practices.

24、ard 32.2-2003. This standard was prepared under the auspices of theAmerican Society of Heating, Refrigerating and Air-Condi-tioning Engineers (ASHRAE). It may be used, in whole or inpart, by an association or government agency with duecredit to ASHRAE. Adherence is strictly on a voluntary basisand m
25、erely in the interests of obtaining uniform standardsthroughout the industry. No changes were made for the 2011 reaffirmation asidefrom minor editorial corrections. 1. PURPOSEThe purpose of this standard is to specify uniform meth-ods of testing for rating the capacity and efficiency of pre-mixand p

Electrical energy input shallbe measured with an integrating instrument with the smallest-scale divis
39、ion reading 0.01 kWh. The instrument shall beaccurate within the limits of 0.5%. Input voltage shall bemeasured with an indicating instrument having an accuracywithin the limits of 0.5% within one year of calibration.5.3 Time Measurement. Time shall be measured withinstruments having an accuracy wit
40、hin 0.1% of the intervalmeasured.5.4 Flow Measurement. Flow shall be measured with adevice that measures mass or volume within an accuracy of1% and a time measurement.6. TEST CONDITIONS6.1 Standard Test Conditions. The test conditions speci-fied in Table 1 shall be used to determine standard perfor-
41、mance.6.2 Voltage and Frequency. Tests shall be performed at thenameplate rated voltage 2% and at the rated frequency 1%.7. TEST PROCEDURE GENERAL REQUIREMENTS7.1 Installation. The dispenser shall bea. installed in accordance with the manufacturers instruc-tions and as it would be installed in servi
42、ce,b. installed in a level position unless the instructions stateotherwise,c. located on the countertop as it would be in service,d. operated with normal lighting and control settings,e. protected against effects of nearby heating or coolingequipment, andf. protected from air moving at more than 50
43、ft/min(0.25 m/s).7.2 Circulation of Air. To restrict the circulation of air atthe rear of the equipment, a vertical partition or wall shall belocated 6 in. (150 mm) from the rear of the cabinet and extendat least 12 in. (300 mm) beyond each side of the cabinet fromthe floor (or countertop) to not le
44、ss than 12 in. (300 mm)above the top of the cabinet.7.3 Measurement of Ambient Temperature. The ambienttemperature shall be measured by a single sensor located12 in. (300 mm) in front of the equipment, at approximatelythe midpoint of the condenser inlet, and maintained at thetemperature specified in
45、 Table 1 throughout the test.8. ENERGY CONSUMPTION TEST8.1 Purpose. The purpose of this test is to determine thedaily energy consumption of a mechanically refrigerated dis-penser operating on standby.8.2 Procedure8.2.1 A temperature-measuring instrument mounted adja-cent to each of the dispenser pro
46、duct temperature control sen-sors shall be used to measure the pre-mix temperature or thewater-and-syrup average temperature.8.2.2 The dispenser shall be filled to the capacity specifiedby the manufacturer. If the dispenser is equipped with temper-ature control, it shall be adjusted to achieve the s
47、pecified stan-dard test temperature for the pre-mix or water and syrup, andthe equipment shall be allowed to stabilize while operatingunder standard conditions. Temperature stabilization is con-sidered to be achieved when the beverage temperature iswithin the specified tolerance at refrigeration cut
48、-out for threesuccessive cycles.8.2.3 The test shall begin once temperature stabilizationhas been achieved, and the following data shall be recorded atleast hourly for at least 24 consecutive hours, including anintegral number of refrigeration cycles:a. ambient temperature,b. relative humidity,c. pr
49、oduct temperature(s) at refrigeration cut-in and cut-out,d. energy consumption in kWh,e. input voltage,f. percent runtime, and g. duration of test.8.2.4 Calculation of Daily Energy Consumption.
