I'm doing a study for a university that is currently operating chillers that use the following refrigerants: R-11, R-12, R-113, R-114, and R-22. Part of the study includes recommendations about what to do with the older chillers that are being used today. I need to know what the market availability of these refrigerants is. More specifically, could the university buy 10,000 lbs. of any one of these refrigerants if they needed to, or is it difficult to get more than, say, 2000 lbs? I just need some ballpark figures to go on. Also, what are the projected trends for the availability of each refrigerant. For instance, will R-12 be purchasable 10 or 15 years in the future, or will it become scarce in 3 years. Perhaps, R-113 is excpected to become rare in the next 10 years. This is the sort of info I need for all these refrigerants. Anyone with a handle on the refrigerant market, please email me at jason.richwine@burthill.com rather than posting a response to this message.

Thanks, Richwine
