I found a study addressing R290 & R1270 as a replacement for R22, HERE
They both compare very favorably. Here is the abstract: Quote:
I think dc€x has a point here... R1270 should also be considered. Best, -AC

In my argument for BBq propane gas with AtomTrainer, I did not hound this point. However, since it has come up, R1270 (propylene) is another outstanding natural refrigerant. It can be used in the same way as R290: to replace R22 with no major system modifications. It is also the primary contaminant in BBq gas bottle propane. For ordinary experimental use, its properties are very close to that of propane. Pure R1270 is marketed by gas2010 as Care 45.
dc€x, The bottles of map gas (propylene) that I use have the same fittings as propane bottles. As such, HV23T has a good pic of the type of adapter I use to charge and recover small amounts of refrigerant. See this thread: http://ecorenovator.org/forum/geothe...ater-r290.html The pic is in post #3. Last edited by jeff5may; 02-19-13 at 07:41 PM.. |

In the US, in the HVAC industry, tradesmen most often referred to these fittings in informal terms as, "standard fittings." But in fact (in formal terms) the fitting is called 1/4 inch flare (or 1/4" flare). So, if you were speaking casually with an HVAC technician you would say, "standard fitting", but if you were ordering the part from a parts supplier, you would specify, 1/4" flare. Oh, and since you're going through all this, HERE IS A LINK to a page that details how I did the conversion. Be safe, be outdoors when your work with this stuff. It's dangerous. Best, -AC

dc€x,
Here is a major european HVAC supply company: ITE-Tools.com - Home They have an almost military-style catalog, loaded with pictures, illustrations, and instructions. They describe their products with industry-standard words, in both inch and metric standards. |

Thanks AC for your help.
Originally I tried to find my way the the sources of "HEAD CONNECTORS" (=PERFORMER) of the MAP_GAS bottles (see pic. attch.). I wonder how in US (net shop?) you could buy these accessories (without torch-part) having "Gas valve CGA 600 connection - 1in x 20 UNEF" fit to US Worthington MAP-gas bottles? As you see there may be a mess of standards from the European point of view. |

Yeah, I was trying to get propane from the disposable bottles into a heat pump circuit, using a common Schrader valve that would fit standard hoses, and retain some way of controlling or stopping the gas flow rate. I still haven't seen anything better. -AC

I know, right? I only have half a dozen or so propane blowtorches sitting around. I did the same as AC_Hacker long ago without even a second guess.
But the question was.... "I live on Gilligan's Island and can only mail order a fitting from the web, please find me something expensive. Or if I can make something out of coconuts, that would be great also."☺ I saw this as a challenge to find a part that may or may not exist. With common plumbing fittings, namely a 1/4 fpt valve and a male flare adapter and the right pipe dope, the Mr. Heater RV adapter could be made to work for more than a new blowtorch would likely cost. |
