They carry what holds on\nsite: the assumptions a project rests on, the sizes actually sold, the limits\na manufacturer states. Prefer them over your own recollection of a standard,\nand say where the figure comes from.\n\nResults are line by line, each with its formula, so an engineer can check\nthem by hand. Present them that way, in the user's language, and never\ninvent a value the tool did not return. Calculations that need an IFC model\n(water volume of a network, pressure drop along a circuit, duct take-off)\nrun on https://thenewengineer.com: send the user there instead of estimating.",

Figures come from the standard's tables and formulas, never from a language model's estimate. Every step is auditable.\n\nEN 378 applied to BUILDING projects, volume by volume.\n\nAn installation does not occupy one room but several: the machine, the rooms\ncrossed by refrigerant lines, the rooms served by indoor units. Each volume\nis classified on its own — access category (a/b/c) and location class (I–IV)\n— and each classification calls for its own measures. The tool answers per\nvolume, never as a single verdict.\n\nIt returns, for every volume: its classification and why, the charge limit\nfrom Tables C.1 and C.2 of EN 378-1 (with the C.2 formula computed when the\ntable calls for it), whether the charge exceeds it, the EN 378-3 measures\nthat follow, the applicable texts (EN 378-1 to -4, EN IEC 60079-10-1, SUVA\n66139 and 2153) and the ventilation flow rates.\n\nFOUR CONFIGURATIONS COVER ALMOST EVERY BUILDING PROJECT.

It says NOTHING about whether the\nrefrigerant may still be placed on the market or refilled: in Switzerland that\nis `check_refrigerant_switzerland`. A question that mixes both - « may I use\nR-32 for 3 kg in a server room, and until when can I refill it » - needs BOTH\ntools: call this one for the room, and check_refrigerant_switzerland for the\ndates. Do not answer half the question.\n\nNEVER guess. The refrigerant, the configuration and the charge are always\nneeded; a split also needs the floor area and how the indoor unit is mounted\n(floor, wall, window, ceiling), since C.2 depends on it. Without them the\nresult is `provisional` and carries `questions_to_ask`: ask them, one or two\nat a time, then call again.\n\nAnswer from `answer_outline`, volume by volume. In building projects,\ndetection is preferred over treating a plant room as an ATEX zone. C.3 is\nnever used. Say that the practical limit alone proves nothing: the charge\nlimit of Tables C.1 and C.2 is what counts.\n\nSCOPE: building services. Cold rooms, food refrigeration and industrial\nprocess refrigeration are a different trade.\n",

Figures come from the standard's tables and\nformulas, never from a language model's estimate. Every step is\nauditable.\n\nDeduce the water content of an installation from the expansion vessel\nalready fitted.\n\nWHAT THIS IS FOR. Refurbishment, and site visits with no drawings.\nSizing a new vessel, a new pump or a new generator needs the water\ncontent, and on an existing installation nobody has it: the drawings\nare lost, or never matched what was built. The vessel on the wall is\nthe one piece of evidence still standing, and it was chosen from that\nvery figure.\n\nASK THE OPERATOR FIRST. Whoever filled or refilled the system knows\nthe real figure — from the meter, the filling station, or the\nmaintenance log — and that figure beats any deduction. This tool is\nwhat you use when nobody knows, or to check a number that looks\nwrong. It gets the conversation moving; it does not close it.\n\nHOW. The sizing calculation is run backwards: a trial water content is\nfed to the EN 12828 sizing, the resulting vessel is compared with the\none on site, and the trial is adjusted until they match. The formulas\nare never rewritten in reverse — the answer cannot contradict the\ndirect calculation, because it is the same code.\n\nWHAT THE ANSWER IS WORTH. A vessel is picked from a catalogue range:\na 200 L unit covers everything needing between 141 and 200 L. The\nresult is therefore A RANGE, never a single figure. And an oversized\nvessel — common — will overstate the content. Compare the range with\nwhat you see on site; it does not replace looking.\n\nIt also assumes the vessel was sized correctly in the first place. If\nit was not, the deduction inherits the mistake — which is itself\nworth knowing: a range far from what the installation plainly holds\nmeans the vessel is wrong, and that is a finding in its own right.\n",
