I have acquired an old fridge and was wondering what procedures are neccessary to remove the refridgerant so i could cut the piping since the evaporator forms the shelves. what would be the best way to do it? Its R134a refridgerant.

umm, like cutting the tubing/pipes? Or do you want to recover it?

u can release R134A into the atomsphere with no problems.. if u do not wish to recover it

Actually if your country abides by the kyoto accord or the Montreal protocol then Realeasing 134A is not legal you must recover it. That said the use of a recover pump is not nessassary if you have a compressor you can use to recover with. Use a recovery tank and hook up the old compressor with a piercing device and cool the tank with a bag of ice. pump the system down to 10 inches of vacume.

HFCs (hydrofluorocarbons)
HFCs are now replacing both CFCs and HCFCs as
refrigerants and air-conditioning fluids. They are not
ozone-depleters at all, and are therefore not subject to
control under the Montreal Protocol. They are, however,
greenhouse gases, contributing to global warming.
Common HFCs: R134a, R404a

Montreal Protocol seems to agree with Gary.

well R134A is probably prohibited not because it's a ozone depleter, but as a greenhouse gas..

Thanks for the info..

Montreal protocol was entirely (as far as I remember) relared to ozone depleting gas (banning of), so it can still be prohibited as a greenhouse gas and not be subject to Montreal protocol.

perfect will check it up with so of the local fridge repair shops, I am gonna have to cut it since the evap is the shelves. Thanks for the info.

The montreal protocol deals with global warming as well as Ozone depletion. Accidental release of refrigerant is not illegal. As leaks always happen in older appliances. The koyoto accords spell out specifically the risks and adresses global warming causes and the means to alleviate this. So if you are in europe where the koyoto accord is in place the rules are tighter R22 and all blends using it are banned or on their way out. The us under Bush rejected the accords But I feel that this is turning in favor of them. Recovering The gas is a simple matter If you have a r22 tank without a check valve that is empty pull a vacume on it and then cool it with ice and salt, and hook it up to the refrigerator service port or use a tapping valve. This will pull the gas out at least 99% of it.... Use an old compressor to pump the rest out.

The point to keep in mind is that politicians the world over are thieves and dictators. They have their greedy little claws deeply embedded in the refrigeration industry, and are unlikely to ease their grip... ever. One way or another, refrigerants that are not now tightly controlled and outrageously taxed, eventually will be.

Exactly either they will be taxed or outlawed it is all about generating revnue. When you are taught business in school you are told that if your produce costs XXX and the profit you wish is x then sale price is xxxx, and is sounds that if you expenses go up you can increase your prices, this does not work for taxes and our politicians need to attend school and relearn the real means to profit it is more about customer service not ow much money I can spend cause we can increase revenue indefinatley to cover our costs o yeah while we are at it we need that 200% cost of living expense...
