Maximum Plantroom Temperatures

[mechieboy1776]

Can anyone inform me as to maximum temperatures allowable in plantrooms?

If so would you be able to reference to relevant literature, thank you.

OK, I see no HVAC types jumped in to help yet. There may be some OSHA regs on the matter, which you should check into.. So with the lack of my technical knowledge in this, let's rough it out and look at it this way,

There is a human comfort zone that runs all the way to "possible heat and possible sun stroke", the later of which I assume you don't even want to think about getting close to, and I would also assume, from my personal experience in extreme heat, that human efficiency decreases with the exponential of proximity to that zone. Take a look at the comfort zone, here

Just looking at that thing, and assuming you're not into building "sweat shops" in Bangladesh or something, I don't think you want to get much higher than a drybulb temp of 83ºF, nor much higher than 70% humidity, unless you like terrible inefficiency and possible revolution of the working force. IMO If you are really trying to be reasonable about the situation, keep it in the zone.

Your real concern should be what equipment is in the room. VFDs and other electronic controls need cool air to run efficently, and low humidity is a must.

IMO, I would look at that equipment and find the one that needs the lowest air temp and humidity level and try to design around that.

I tend to think that the one human being that's watching all the equipment is the one that needs to be looked after. If he's not in the room because its too hot or too humid when the alarm goes off, what good is having all that equipment really going to do for you?
