| Detecting leaks in the refrigerant gas loop |
| The refrigerant gas loop may have leaks due, for example, to external damage. |
| To detect small leaks, because only a tiny amount of refrigerant gas has been spilled, one may use, for example, an electronic leak detector or a leak detection additive introduced into the refrigerant gas loop. |
| 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. |
Note | Leak detection devices that are appropriate for R12 refrigerant gas do not work with R134a refrigerant gas, as the latter does not contain the chlorine atoms which would be detected by the R12 leak detectors. |
