6、 1.1 Purpose. For practical, safety and environmental reasons, there is a need for content recovery and proper recycling of refrigerant cylinders. This document is a guideline for content recovery and recycling of cylinders at the end of their useful service life. This document is not intended to be

7、 an exhaustive listing of all good practices or requirements. Applicable federal, state and local requirements should be reviewed. 1.1.1 Intent. This guideline is intended for the guidance of the industry, including manufacturers, engineers, installers, contractors, users, refrigerant reclaimers and

8、 metal recyclers 1.1.2 Review and Amendment. This guideline is subject to review and amendment as technology advances. Section 2. Scope 2.1 Scope. This guideline is applicable to all U.S Department of Transportation (DOT) non-refillable and refillable fluorocarbon refrigerant cylinders, as defined i

9、n Section 3, having water capacity greater than two pounds used to transport refrigerants sold in the United States. 2.2 Exclusions. This guideline does not apply to drums used to ship refrigerants. Section 3. Definitions All terms in this document will follow the standard industry definitions in th

10、e current edition of ASHRAE Terminology of Heating, Ventilation, Air-Conditioning, and Refrigeration unless otherwise defined in this section. For the convenience of the users of this guideline, definitions for the more important terms employed in this guideline are provided below. 3.1 DOT-39 Non-Re

11、fillable Cylinder. A single-use container produced in accordance with Title 49, Code of Federal Regulations, Section 178.65. 3.2 DOT Refillable Cylinder. A refillable container produced in accordance with the Title 49, Code of Federal Regulations, Section 178.36 (DOT 3A), 178.37 (DOT 3AA), 178.51 (D

12、OT 4BA) or 178.61 (DOT 4BW) or as specified in an applicable special permit authorization as provided by the cylinder manufacturer. 3.3 Empty State. 3.3.1 Non-Refillable Cylinder. A cylinder whose contents have been evacuated to a vacuum of 15 inches of mercury, relative to standard atmospheric pres

13、sure of 29.9 inches of mercury. 3.3.2 Refillable Cylinder. A cylinder whose contents have been recovered to an internal pressure of 0 psig or less with the intent to return it to the owner for proper handling. 3.4 End User. The individual or entity that renders the cylinder empty as defined in 3.3.

14、3.5 Metal Recycler. A business or organization that processes or recycles industrial consumed scrapped material in a sound, environmentally responsible manner. 3.6 Recover. To remove refrigerant from a cylinder at the end of its useful service life and store it in a properly pressure rated recovery

15、cylinder. 3.7 Should. “Should“ is used to indicate provisions which are not mandatory but which are desirable as good practice. AHRI Guideline Q-2010 2 3.8 Special Permit Cylinder. A cylinder that has been authorized by the DOT to be manufactured outside the scope of existing DOT regulations but in

16、accordance with the requirements specified by DOT in a special permit. The requirements in the special permit may include design, composition, manufacture, testing, marking, and transportation criteria as well as special provisions. Section 4. Responsibilities 4.1 Responsibilities. It is the respons

17、ibility of the End User to verify that any residual refrigerant contents are recovered from the cylinder while the cylinder is still under the control of the End User. Section 5. Procedure 5.1 Labeling Recommendations. 5.1.1 Recommended Label for DOT-39 Non-Refillable Cylinder. “Do not vent residual

18、 pressure to the atmosphere. Recover residual contents using proper recovery equipment, hoses and gauges to a vacuum of 15 inches of mercury. Observe all precautions printed on the cylinder labels. After recovery, close valve and return for proper recycling or open valve and pierce rupture disc acco

19、rding to Section 5.3. Do not reuse. Cylinder should be returned for proper metal recycling.” 5.1.2 Recommended Label for DOT Refillable Cylinder. “Do not vent residual pressure to the atmosphere. Observe all precautions printed on the cylinder labels. Close valves tightly. Promptly return to supplie

20、r.” 5.2 Residual Content Recovery Procedures. Disposition of refrigerants must be in compliance with all applicable federal, state and local regulations. 5.2.1 Valves should remain closed at the onset of the refrigerant recovery process. 5.2.1.1 Recover refrigerant from cylinder into an appropriate

21、pressure-rated recovery cylinder to empty state as listed in Section 3.3. 5.2.1.2 For non-refillable cylinders only, open the valve on the cylinder. Verify cylinder is empty. 5.2.2 IMPORTANT: DO NOT MIX REFRIGERANTS that have different ASHRAE numbers into the same recovery container. 5.3 Cylinder Re

22、cycling Recommendations 5.3.1 DOT-39 Non-Refillable Cylinder. Do not reuse cylinders. Cylinder must be emptied of their contents as described in 5.2.1. After emptied of their contents, open valve. Cylinders may be rendered to a recyclable condition by the following method. WARNING: Failure to follow

23、 these instructions for safe disposal of the non-refillable refrigerant cylinder can result in an immediate release of contents resulting in personal injury, property damage or both. Read all tank warnings for more information. 5.3.1.1 Place the tip of a flat-headed screwdriver on the inside serrati

24、on of the rupture disc located on the shoulder of the tank (see Photo 1). Photo 1: Placement of Screwdriver for Piercing AHRI Guideline Q-2010 3 5.3.1.2 With a hammer or mallet, LIGHTLY tap the handle of the screwdriver to pierce the rupture disc open (see Photo 2). Photo 2: Pierce Rupture Disc 5.3.

25、1.3 Carefully, completely open the rupture disc. With a permanent magic marker, draw a large circle around the open rupture disk and write the word “EMPTY” on the tank (see Photo 3). Photo 3: Open Rupture Disc 5.3.1.4 Once the rupture disc is open, the tank can be recycled with other steel recyclabl

26、es at your local steel recycling center. 5.3.2 DOT Refillable Cylinder. Valves should be closed tightly and hood cap securely placed, if applicable. Cylinders should be returned to supplier or owner. AHRI Guideline Q-2010 4 APPENDIX A. REFERENCES NORMATIVE None. APPENDIX B. REFERENCES INFORMATIVE B1
