Knowledge base for refrigeration and air conditioningwhen someone on the roof asks about the log book, inspection record and setpoints.

That is exactly where you lack the history, and it rarely came along with the switch. What you have is the first service report, the photo of the plate, perhaps a schematic from the previous contractor and the email with which the customer switched. That can go in and is assigned to the system, not just to the customer; something is added with every job. If you ask about the last leak check and the knowledge base finds nothing, it says so. Whether several systems in the same building are kept cleanly apart is a point to check in the demo.

Both, just different things. In Austria, the Refrigeration Systems Ordinance (Kälteanlagenverordnung) requires an inspection log book for a charge of more than 1.5 kilograms, to be kept on site so that it can be shown to the authorities at any time: the details from the refrigeration unit’s rating plate, every inspection with date and defects found, certificates of pressure tests, major repairs and significant changes. It must be kept for as long as the system is installed and in operation. The records of leak checks are likewise owed by the operator under the EU F-gas Regulation, for at least five years — but only certified personnel, that is you, may carry out and document the checks. The knowledge base replaces neither and writes into neither. You can query your side of it, and if the knowledge base finds no entry for a system, it says so.

It isn’t supposed to: if the report has no quantity, the answer shouldn’t have one either, but should point to the report in which it is missing. That is exactly the kind of case you should try out in the demo. It is inconvenient, and rightly so, because more than the invoice depends on the charge. The check interval depends on the CO₂ equivalent, that is, quantity times the global warming potential of the refrigerant, and is staggered at twelve, six or three months depending on the threshold — doubled in each case with a permanently installed leak detection system. If you don’t know the quantity, you don’t know the interval. Only you can close the gap; it should become visible instead of disappearing in a binder.

Ideally not as a separate task at all. Whether Streit or pds can be connected for you, we check before we start; setting it up is charged by effort. Mirroring is encrypted and uses outgoing connections only — no open port, no access to your network from outside, and nothing is changed on your system. Until then, uploading is enough: reports, photos of the plate, voice notes after the job, even whole folders at once. Anyone who writes things down anyway doesn’t write more because of this — just in one place, where it can be found next July.
