9、LTERS AND SUCTION-LINE FILTER-DRIERS Section 1. Purpose 1.1 Purpose. The purpose of this standard is to establish, for refrigerant Suction-Line Filters and Suction-Line Filter-Driers (which may be referred to herein as “filters“): definitions; test requirements; rating requirements; minimum data req
10、uirements for Published 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
11、 amendment as technology advances. Section 2. Scope 2.1 Scope. This standard applies to Suction-Line Filters and Suction-Line Filter-Driers, as defined in Section 3. 2.2 Refrigerant. This standard applies to Suction-Line Filters and Suction-Line Filter-Driers for use in systems employing halocarbon
12、refrigerants R-12, R-22, R-134a, R-404A, R-407C, R-410A, R-502, and R-507A, as defined in ANSI/ASHRAE 34 with addenda. Section 3. Definitions All terms in this document follow the standard industry definitions in the current edition of ASHRAE Terminology of Heating, Ventilation, Air Conditioning and
13、 Refrigeration unless otherwise defined in this section. 3.1 Permanent Installation. An installation intended to remain in the system for an indefinite period. 3.2 Published Rating. A statement of the assigned values of those performance characteristics, under stated Rating Conditions, by which a un
14、it may be chosen to fit its application. These values apply to all 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
15、 other literature controlled by the manufacturer, at stated Rating Conditions. 3.2.1 Application Rating. A rating based on tests performed at application Rating Conditions (other than Standard Rating Conditions). 3.2.2 Standard Rating. A rating based on tests performed at Standard Rating Conditions.
16、 3.3 Rating Conditions. Any set of operating conditions under which a single level of performance results and which causes only that level of performance to occur. 3.3.1 Standard Rating Conditions. Rating conditions used as the basis of comparison for performance characteristics. 3.4 Refrigerant Flo
17、w Capacity. The flow of refrigerant liquid, expressed as Tons of Refrigeration or mass flow rate, for a given refrigerant under specified conditions, which the filter will pass and not exceed the specified Pressure Drop. 3.4.1 Pressure Drop. The pressure difference between the inlet and outlet of a
18、filter, including its connections expressed in psi kPa. 3.4.2 Ton of Refrigeration. A useful refrigerating effect equal to 12,000 Btu/h 3.5 kW.

Where “shall“ or “shall not“ is used for a provision specified, that provision is mandatory if compliance with the standard is claimed. 3.5.2 Should. “Should“ is us
20、ed to indicate provisions which are not mandatory, but which are desirable as good practice. 3.6 Suction-Line Filter. A manufactured device used in the suction line of a system, for the purpose of removing and retaining solid contaminants from the refrigerant. 3.7 Suction-Line Filter-Drier. A manufa
21、ctured device used in the suction line of a system, whose element is partly or wholly composed of a desiccant. It is intended to remove and retain moisture as well as solid contaminants from the refrigerant. 3.8 Temporary Installation. An installation intended to remain in the system for a short per
22、iod of time with the purpose of cleaning a new or severely contaminated system. Section 4. Test Requirements 4.1 Test Requirements. All filter and filter-drier capacity ratings shall be based on tests in accordance with, or subject to verification by, the test procedure of ANSI/ASHRAE Standard 78. 4
23、.1.1 If the filter capacity depends upon the position of or direction of flow through the filter, the filter shall be tested for all variations for which ratings are published. Section 5. Rating Requirements 5.1 Published Ratings. As used herein, the term Published Ratings includes the ratings shown
24、 on the filter or published in specifications, advertising or other literature controlled by the manufacturer at stated Rating Conditions. Published Ratings shall include Standard Ratings, and may also include Application Ratings (See Table 1). 5.2 Standard Ratings. Standard capacity ratings of filt
25、ers for refrigerant suction-line service shall be stated in Tons of Refrigeration, tons kW and/or mass flow rate, lb/min kg/s. The following specified conditions shall be used to determine the refrigerant flow rate through the filter. 5.2.1 Standard Rating Conditions. Standard Rating Conditions shal
26、l be: Evaporator saturation temperature 40F 4.4C Vapor temperature leaving evaporator 50F 10C Vapor temperature entering filter 65F 18C Liquid temperature entering expansion device 90F 32C Pressure Drop for R-22, R-404A, R-407C, R-410A, R-502 and R-507A 3.0 psi 21 kPa Pressure Drop for R-12 and R-13
27、4a 2.0 psi 14 kPa 5.2.2 Application Rating Conditions. In addition to ARI standard capacity ratings at the conditions specified in 5.2.1, capacity ratings may also be published for other evaporator temperatures or pressure drop values, provided they are specified as such and are based on all the oth
28、er provisions of this section (See Table 1). 5.3 Tolerances. To comply with this standard, published capacity ratings shall be based on the requirements of this section, and shall be such that any production Suction-Line Filter or Suction-Line Filter-Drier selected at random and tested shall have a
29、capacity not less than 95% of its Standard Rating.

Minimum Data Requirements for Published Ratings 6.1 Minimum Data Requirements for Published Ratings. As a minimum, Published Ratings shall i
33、nclude all Standard Ratings. All claims to ratings within the scope of this standard shall include the statement “Rated in accordance with ARI Standard 730“. All claims to ratings outside the scope of this standard shall include the statement “Outside the scope of ARI Standard 730”. Wherever Applica
34、tion Ratings are published or printed, they shall include a statement of the conditions at which the ratings apply. Section 7.
