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

That’s exactly where you lack the history, and it rarely comes with you when a customer switches. What you have is the first service report, the photo of the plate, perhaps a schematic from the previous contractor and the email in which the customer moved over to you. All of that can go in and is assigned to the system, not just the customer; every job adds something. If you ask about the last leak check and the knowledge base finds nothing, it tells you so. Whether several systems in the same building are kept cleanly apart is worth checking in the first weeks after go-live.

Both, but different things. In Austria, the Refrigeration Systems Ordinance (Kälteanlagenverordnung) requires an inspection log book for charges of more than 1.5 kilograms, 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 its date and any defects found, pressure test certificates, major repairs and significant changes. It must be kept for as long as the system is installed and in operation. Under the EU F-gas Regulation, the operator is likewise responsible for keeping the leak check records, 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 to neither. You can search your side of it, and if the knowledge base finds no entry for a system, it tells you so.

No. It answers only from your documents: if the report has no quantity, the answer gives none either and points to the report where it is missing. That’s exactly the kind of case to check with your own reports in the first weeks after go-live. It’s inconvenient, and rightly so, because more than the invoice depends on the charge. The check interval depends on the CO₂ equivalent – the quantity multiplied by the refrigerant’s global warming potential – and is set at twelve, six or three months depending on the threshold, doubled in each case if a permanent leak detection system is installed. If you don’t know the quantity, you don’t know the interval. Only you can close the gap; but this way it becomes visible instead of disappearing into a binder.

Ideally, it shouldn’t be a separate task at all. Before we start, we check whether Streit or pds can be connected for you; setting it up is charged on a time-and-materials basis, agreed in advance. 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 won’t write any more because of this – just in one place, where it can be found next July.
