Abstract
A useful and accurate refrigerant leak rate measurement approach is presented, which will find small leak rate as low as 3 g, by utilizing liquid nitrogen as cold recourse to cool down the recovery tank, and as an alternative, the dry ice (liquidized carbon dioxide) is tested too, but it is found that the recovery accuracy can reach to 10 only.
