Dear Ward<br><br>
I would like to provide a solution to the second part of the question.
Thus retrofitting R22 . At parent there are two alternatives. You can use
R-717 (ammonia) and in situation where R-717 cannot be used
directly, that is case where leakage is not tolerated, then the
alternative is R-744 (Carbon dioxide) <br>

<font face="Verdana" size=2>Can anyone provide me with a source for a
carbon emission factor for volume of R-22 refrigerant used for older
cooling systems? R-22 I believe is also known as HCFC-22 (chemical
formula: CHClF2). Also I would appreciate any information from anyone who
has successfully retrofitted a cooling system using R-22 for a more
environmetnally responsible alternatives. <br>
