The purpose of this standard is to establish for Refrigerant Liquid Receivers: definitions; rating requirements; minimum data requirements for Publish
9、ed Ratings; marking and nameplate data; and conformance conditions. 1.1.1 Intent. This standard is intended for the guidance of the industry, including manufacturers, engineers, installers, contractors and users. 1.1.2 Review and Amendment. This standard is subject to review and amendment as technol
10、ogy advances. Section 2. Scope 2.1 Scope. This standard applies to separately installed Refrigerant Liquid Receivers for field-erected systems only. Section 3. Definitions All terms in this document shall follow the standard industry definitions in the current edition of ASHRAE Terminology of Heatin
11、g, Ventilation, Air Conditioning and Refrigeration, unless otherwise defined in this section. 3.1 Published Rating. A statement of the assigned values of those performance characteristics, under stated Rating Conditions, by which a unit may be chosen to fit its application. These values apply to all
12、 units of like nominal size and type (identification) produced by the same manufacturer. The term Published Rating includes the rating of all performance characteristics shown on the unit or published in specifications, advertising or other literature controlled by the manufacturer, at stated Rating
13、 Conditions. 3.1.1 Application Rating. A rating based on tests performed at application Rating Conditions (other than Standard Rating Conditions). 3.1.2 Standard Rating. A rating based on tests performed at Standard Rating Conditions. 3.2 Rating Conditions. Any set of operating conditions under whic
14、h a single level of performance results and which causes only that level of performance to occur. 3.2.1 Standard Rating Conditions. Rating Conditions used as the basis of comparison for performance characteristics. 3.3 Refrigerant Liquid Receiver. A vessel in a refrigerating system designed to ensur
15、e the availability of adequate liquid refrigerant for proper functioning of the system, and to store the liquid refrigerant when the system is pumped down. 3.4 “Shall“ or “Should“.“ “Shall“ or “Should“ shall be interpreted as follows: 3.4.1 Shall. Where “shall“ or “shall not“ is used for a provision
16、 specified, that provision is mandatory if compliance with the standard is claimed. 3.4.2 Should. “Should“ is used to indicate provisions which are not mandatory but which are desirable as good practice. Section 4. Rating Requirements 4.1 Rating Requirements. Capacity ratings for Refrigerant Liquid
17、Receivers shall be determined with the maximum being 80% of the gross internal volume of the receiver, expressed in ft3m3 or expressed in lb kg, of any specified refrigerant, assuming saturated liquid refrigerant density (ASHRAE Handbook Fundamentals) at 90F 32 C.

To comply with this standard, storage capacity shall be based on data obtained in accordance with the provisions of this
19、 standard and shall be such that any production unit, when tested, shall show a capacity not less than the rated capacity. Section 5. Minimum Data Requirements for Published Ratings 5.1 Minimum Data Requirements for Published Ratings. As a minimum, Published Ratings shall include all Standard Rating
20、s. All claims to ratings within the scope of this standard shall include the statement “Rated in accordance with ARI Standard 495.” All claims to ratings outside the scope of this standard shall include the statement “Outside the scope of ARI Standard 495.” Wherever Application Ratings are published
21、 or printed, they shall include a statement of the conditions at which the ratings apply. 5.2 Information to be Published. Manufacturers literature for each model shall include: a. Liquid refrigerant storage capacity, ft3m3, or lb kg for a specified refrigerant b Size of refrigerant connections, in
22、mm c. Type of refrigerant connections d. Maximum design pressure, psig kPagauge e. Refrigerants for which the vessel is suitable per ANSI/ASHRAE 34 with Addenda Section 6. Marking and Nameplate Data 6.1 Marking and Nameplate Data. As a minimum, each Refrigerant Liquid Receiver shall have the followi
23、ng information shown on its nameplate(s): a. Manufacturers name b. Manufacturers model or serial number c. Maximum design pressure, psig kPagauge d. Liquid refrigerant storage capacity, ft3m3, or lb kg for a specified refrigerant Section 7. Conformance Conditions 7.1 Conformance. While conformance w
24、ith this standard is voluntary, conformance shall not be claimed or implied for products or equipment within the standards Purpose (Section 1) and Scope (Section 2) unless such product claims meet all of the requirements of the standard and all of the rating requirements are reported in complete com
25、pliance with the standard. Any product that has not met all the requirements of the standard shall not reference, state, or acknowledge the standard in any written, oral, or electronic communication.
