Refridgerants

[PDR]

Is there a liquified gas refrigerant that comes close to meetikng the following:

1. A vapour pressure of at least 80psi at 0degC
2. A vapour pressure of no more than 200psi at 60degC
3. Can be legally vented to the atmosphere
4. Can be purchased by the public

I’m asking because years ago radio controlled scale model aircraft had retractable undercarriage systems that were powered by Freon (which you can no longer get, obviously), and compressed air simply doesn’t work as well, so I’m looking for an alternative.

Thanks,

Sorry – all refrigerants used by domestic appliance companies are controlled substances. Those that are required to be recovered such as R134a must be recycled or disposed of. Those that are not ozone depleting have got to be recovered for further use.

Is’nt it daft that the odd gram that you would be venting to atmoshere is restricted. Yet the USA is legally allowed to pollute the whole world with its discharge and the rest of the world sits by and lets them do it.

Here in this country its illegal and a criminal offence to pollute and not recycle, doesn’t seem like a level playing field, does it?

Thanks for that – I suspected it might be the case, but I thought it was worth asking the question.
