  1. R-22 Alternative Refrigerants for Retrofit Part 1: Impact of the R-22 Phase-out Part 2: Managing Existing R-22 Resources Part 3: R-22 Refrigerant Alternatives for Retrofit

  2. Rick Roland is the owner and engineer of Certified Refrigerant Services, Inc. which is located in Punta Gorda, Florida. Rick has been in the refrigerant reclamation industry since its inception in 1995; one of the first reclaimers in the country. From the age of ten, he grew up in his father’s HVAC company and eventually became the owner of a Carrier Leadership dealer culminating over 40 years of hands-on experience. Rick has designed and built all the refrigerant reclaim and separation equipment used at CRS including a patent pending Modular Separation Machine™ (MSM). This advance technology is only possible by possessing an acute understanding of refrigerants and their technical characteristics. Rick is a well known qualified leader and authority in the refrigerant management industry.

  8. Part 1 Impact of the R-22 Phase Out

  9. R-22 Phase-Out Schedule

  10. EPA Forecast 2010

  11. R-22 Phase-Out Schedule

  12. EPA Projected R-22 Servicing Demand by End User 2010 62,500 MT (137,787,500 lbs.)

  13. EPA Projected R-22 Servicing Demand by End User 2015 38,800 MT (185,538,480 lbs.)

  14. Question What is the Current Status of R-22?

  15. Part 2 Existing R-22 Management

  16. Who Controls R-22 Availability & Price?

  17. YOU! • By recovering R-22 • By returning R-22 for reclaim • You keep a local inventory available which also keeps prices stable

  18. Existing R-22 Management • Rule #1: • Rule #2: Get involved with R-22 return programs that benefit your company • Rule #3: Don’t mix any other refrigerants with your recovered R-22! Don’t VENT!

  19. Part 3 R-22 Alternatives So now we’re in season and what if there’s NO R-22?

  20. R-22 Alternatives Unlike R-22 the R-4XX alternative refrigerants are BLENDS, or “zeotropic.” ZEO Who?

  21. Zeotrope: A mixture made up of two or more refrigerants with different boiling points. Zeotropic mixtures are similar to near-azeotropic mixtures with the exception of having a temperature glide greater than 10° F. Zeotropic mixtures should be charged in the liquid state. Azeotrope A mixture made up of two or more refrigerants with similar boiling points that act as a single fluid. The components of azeotropic mixtures will not separate under normal operating conditions and can be charged as a vapor or liquid.

  22. Question How many have performed an R-22 system retrofit to an alternative refrigerant?

  23. Choosing An R-22 Alternative Refrigerant R-404a R-125 (44%) R-143a (52%) R-134a (4%) R-407c R-125 (25%) R-32 (23%) R-134a (52%) R-417a R-125 (46.6%) R-600 (3.4%) R-134a (50%) R-421a R-125 (58%) Proprietary Oil R-134a (42%) R-422b R-125 (55%) R-600 (3%) R-134a (42%) R-422d R-125 (65.1%) R-600 (3.4%) R-134a (31.5%) R-507 R-125 (50%) R-143a (50%)

  24. What Do We Want From Our R-22 Alternative Refrigerant? • No Major Hardware Changes To Equipment • Use The Same Oil Type • Fast, Simple Conversion • Sufficient Capacity • At Least the Same Energy Efficiency • Reliability • Same Toxicity • Flammability Classification as R-22 • Zero Ozone Depleting Potential • Reasonable Cost

  25. Download guidelines from Technical Reference Library – www.certifiedrefrigerant.com R-407C • Recover the R-22 from the system • Remove the compressor • Remove the mineral oil from the compressor • Reinstall the compressor • Vacuum system • Add POE oil & the R-407C refrigerant charge • Run system for 72 hours • Test the system oil to assure the it is < 1% residual mineral • Repeat entire procedure if necessary

  26. Download guidelines from Technical Reference Library – www.certifiedrefrigerant.com R-404A • Recover the R-22 from the system • Remove the compressor • Remove the mineral oil from the compressor • Reinstall the compressor, with POE oil, vacuum the system • Reinstall the original R-22 charge • Run system and test for the residual mineral oil. 5% or less is acceptable • With the correct oil content, recover the R-22, vacuum the system and recharge with R-404A • Adjust the system charge and refrigerant flow.

  27. Download guidelines from Technical Reference Library – www.certifiedrefrigerant.com R-417A • Recover the R-22 from the system • Weigh the R-22 removed • Vacuum the system • Add 90% of the weight of the R-22 charge • Run system • Adjust the system charge and refrigerant flow as required

  28. Download guidelines from Technical Reference Library – www.certifiedrefrigerant.com R-422A/B/C/D • Recover the R-22 from the system • Weigh the R-22 removed • Vacuum the system • Add 90% of the weight of the R-22 charge • Run system • Adjust the system charge and refrigerant flow as required • Flow control devices may need to be changed.
