formula assumes that leak rates between a first and second additions of refrigerant (when repairs have not been made) will continue at that rate for 365 days. It is incorrect to assume compliance with the leak rates by allowing appliances to leak up to the thresholds (15% and 35%) before repairs are initiated. Calculating a Leak Rate 1.

  • Guide to Good Leak Testing - US EPA

    Commercial and industrial refrigeration and air conditioning systems leak too much refrigerant – leaks of up to 30% of the charge during a year are not uncommon. Leak rates do not have to be this high. Adherence to best practice in service, maintenance leak testing and repair can significantly reduce refrigerant losses. This guide shows you how.
