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

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.

Question What is the Current Status of R-22?

Part 2 Existing R-22 Management

Who Controls R-22 Availability & Price?

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

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

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

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

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.

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

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 Download guidelines from Technical Reference Library –

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. Download guidelines from Technical Reference Library –
