| The refrigerant gas circuit may have leaks due to external damage, for example. To detect small leaks, an electronic leak detector or a leak detection additive introduced into the refrigerant gas loop may be used, because only a tiny amount of refrigerant gas in liquid form is spilled. Electronic leak detection devices can detect annual refrigerant gas losses of less than 5 grams. (There are various devices of this type, specifically adapted to the composition of the respective refrigerant gases. For example, leak detection devices that are appropriate for R12 refrigerant gas do not work with R134a, as the latter does not contain the chlorine atoms which would be detected by the specific leak detection device) → Chapter. |
