13、ta; 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 technology advances. Section 2. Scope 2.1 S
14、cope. This standard applies to Non-Condensable Gas Purge Equipment for use with Low Pressure Centrifugal Liquid Chillers as defined in Section 3. This standard defines general equipment requirements, test methods and analysis techniques used to determine the performance rating for Purge Equipment th
15、at remove Non-Condensable gases from Low Pressure Centrifugal Liquid Chillers. This purge equipment is typically used in conjunction with chillers which operate with at least a portion of the system below atmospheric pressure. Section 3. Definitions All terms in this document shall follow the standa
16、rd industry definitions in the current edition of ASHRAE Terminology of Heating, Ventilation, Air-Conditioning, and Refrigeration unless otherwise defined in this section. 3.1 Bubble Point. Refrigerant liquid saturation temperature at a specified pressure. 3.2 Dew Point. Refrigerant vapor saturation
17、 temperature at a specified pressure. 3.3 Low Pressure Centrifugal Liquid Chiller. A Centrifugal Liquid Chiller that typically has a portion of the refrigerating system below atmospheric pressure (100 kPa) when operated at typical conditions for comfort cooling applications. 3.4 Non-Condensable Gase
18、s. Gases which do not condense at normal operating temperatures and pressures in centrifugal water-chiller condensers, such as nitrogen and oxygen. 3.5 Published Rating. A statement of the assigned values of those performance characteristics, under stated Rating Conditions, by which a unit may be ch
19、osen to fit its application. These values apply to all units of like nominal size and type (identification) produced by the same manufacturer. As used herein, the term Published Rating includes the rating of all performance characteristics shown on the unit or published in specification, advertising
20、 or other literature controlled by the manufacturer, at stated Rating Conditions. 3.5.1 Application Rating. A rating based on tests performed at Application Rating Conditions (other than Standard Rating Conditions). 3.5.2 Standard Rating. A rating based on tests performed at Standard Rating Conditio
21、ns. 3.6 Purge Equipment. A device which will separate Non-Condensable Gases from refrigerant and remove them from the refrigeration system. 3.6.1 Automatically Regenerated Media. Media that is recycled at the purge system to remove entrained refrigerant and return this refrigerant to the chiller. Th
22、e regeneration process is initiated automatically by the purge control system. 3.6.2 Manually Regenerated Media. Media that is recycled at the purge system to remove entrained refrigerant and return this refrigerant to the chiller. The regeneration process is setup and initiated by an operator. 3.6.
23、3 Refrigerant Holding Capacity. The amount of refrigerant, designated by the manufacturer, at which the media on the purge device needs to be replaced or regenerated. 3.6.4 Replaceable Media. Media that is removed from the system and replaced with new or recycled media. The media from the system is
24、processed to ensure refrigerant is not released to the atmosphere. 3.7 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.

Rating Conditions used as the basis for comparison of performance characteristics. 3.8 “Shall“ or “Should.” “Shall“ or “should“ sh
26、all be interpreted as follows: 3.8.1 Shall. Where “shall“ or “shall not“ is used for a provision specified, that provision is mandatory if compliance with the standard is claimed. 3.8.2 Should. “Should“ is used to indicate provisions which are not mandatory but which are desirable as good practice.
27、Section 4. Test Requirements 4.1 Test Requirements. Non-Condensable Gas Purge Equipment shall be tested in accordance with the procedures set forth in Appendices C and D of this standard. The analysis of the discharge gas sample shall be processed via the activated carbon technique in Appendix E or
28、the gas chromatograph technique in Appendix, F or an equivalent alternative test method. If alternative test methods are employed for the gas chromatograph technique, the user must be able to demonstrate that they produce results at least equivalent to the specified testing method Section 5. Rating
29、Requirements 5.1 Purge Equipment Concentration Rating. Purge Equipment exhaust gas concentration shall be expressed in g refrigerant / g air. 5.2 Operating Conditions for Purge Equipment Rating. The Purge Equipment efficiency rating point shall be established with a chiller operating at the followin
30、g conditions: a. Condenser refrigerant pressure at a nominal dew point temperature of 29EC “ 0.5EC. Allowable pressure limits during the test are equivalent to a dew point temperature range of 28 to 31EC. b. Ambient temperature at 25EC “ 1.0EC c. Evaporator refrigerant pressure at a bubble point tem
31、perature of 4.0EC or greater d. For Purge Equipment designs that use adsorption or absorption devices to selectively separate refrigerant and air, these devices shall be brought to a normal operating condition prior to test. See Appendix D for specific rating and testing instructions. This may inclu
32、de saturating and then regenerating a device or bringing oil supplies to a typical refrigerant concentration. 5.3 All tests shall be performed at the nameplate rated voltage and frequency or as otherwise specified in this standard. For units with dual nameplate voltage ratings, standard rating tests
33、 shall be performed at both voltages, or at the lower of the two voltages if only a single standard rating is to be published. 5.4 Tolerances. If conformance with this standard is claimed for a Published Rating, then any Purge Equipment tested, following the procedures of Appendices C, D, E and F, s
34、hall not have exhaust gas concentration greater than the Published Rating. If a Manually Regenerated or Replaceable Media is used, then the refrigerant exhaust gas concentration should not be greater than the Published Rating when the absorptive medium has been filled with the amount of refrigerant,
35、 specified by the manufacturer as the Refrigerant Holding Capacity. Section 6. Minimum Data Requirements for Published Ratings 6.1 Minimum Data Requirements for Published Ratings.
