Dear Margaret:

 

My intention for HCR188C is to be used in new refrigerators and new home
air conditioners units.To retrofit a refrigerator or AC  home unit is
not feasible because of cost.

 

The normal home window unit 12000 BTU is around $200.00 and the
normal-sized refrigerator is  approx $500.00. Whenever one fails, it is
cheaper to buy a new one and not fix it. 

 

I guess I did not clarify this. 

 

Most of the exposure of HCR188c would be at a factory when they charge
the new system. 

 

If there is a failure or warranty, they would just discard it and the
store would replace it with a new one. The old one is scrapped. Scrap
yards just recycle the unit by removing the refrigerant and sell it as
propane for the barbecue grill. It would be easier to blend the
refrigerant from new hydrocarbons. 

 

I have used a Robin air EPA-approved reclaimer for HCR188c which has an
oil-separator

which separates the compressor oil from HCR188C and recycles HCR188C
back into a canister. I found it much more effective using the recycled
refrigerant in a BBQ charcoal burner. It can be reused as a refrigerant
but my own personal feeling is that it is such a small amount and that
part of the blend might get lost in the process so I would rather have a
brand new blend in an air conditioner. Although I've used it over and
over many times, the barbecue grill was the best.

 

At Cortland, New York while testing my refrigerant at Intertek in
February of this year, I did ask Rob Hill about a reclaimer for
Hydrocarbon Refrigerant, All he told me was that there was no company
that he knows is doing it since the EPA has not approved it as an
Alternative Refrigerant.

 

I will ask him again in writing and get his response.

 

If this is part of a satisfactory explanation then I will get the rest
of the clarification to you

in a formal letter.

 

Thank you 

Richard
