français vers anglais Technique / Génie Ingénierie (général) specification manual

In an air-conditioning spec manual. "Aérorefrigérant" is just one of a number of terms that have many possibilities depending on the context. I've been using the Grand Dictionnaire Terminologique (Quebec) on the internet but in many ways it is not entirely helpful.

So, for this term, I have "cooling tower" - but it may be, perhaps, "fan-coil unit" - etc., etc.

Does anyone know of a site that could give me a good glossary of English air-conditioning engineering terms - so I don't have to keep bothering people on this site?

Thanks, as always, for help rendered.
