A similar experience in a flour mill control room. Engineer says this is perfectly sized for your environment. Being slightly aware of the calculations needed and where to find the information to do a slightly better job. I pointed out that the machine supplied was one third the output it should be (for just about meet the spec control of room temperature for testing purposes) and possibly one quarter of the output for a bit of reserve on the warmest days.
Engineer bitched a bit, manglement spent the money on the just about adequate solution and we were able to test flour at the correct temperature for the rest of my time there and be comfortable when the roller floor was running in excess of 30C.
I have met one or two of the cowboy HVAC chaps. A flour mill control room that needed to be a 20C to measure dough water absorption accurately. Too much water or too little in the bakery dough meant either too much space in the plastic bread wrapper or a mess of crumbs and plastic as the machines try to stick big loaves in too small bags!
Control room had 2 or 3 500w meat based heat radiators, a 1 megawatt facitilty outside and sundry control PC's or PLC's installed. Said cowpoke couldn't work out why the temperature couldn't get below 25C with a 2.5KW unit. The 7.6KW unit that we replaced it with coped much better but the 'engineer' was unhappy that a 'civilian' had worked it out for him.
Nobody gives a toss until the excrement hits the air-conditioning. Then watch as HSE roll up and start charging for their time from arrival, before inviting people for a date at the court to try and prove that they are innocent. That's when management attitudes start to change.
