Ok, previously I posted about the poor heat-management on my second floor, the apparent difference between the thermostat temp reading and that of an alcohol thermometer my wife, the Chemist, brought home a couple of weeks ago.
So, this morning I woke early and decided to go keep quiet in my computer room, which is just another bedroom on the floor and get’s the morning sun. So, the thermostat is set to 74ºF, is reading 74ºF, and the termometer reads 26ºC (or about 79ºF).
Now, this is at 6AM that these conditions exist. So, I go into the computer room, turn two PCs on, close the door and begin gulping my quart of hot coffee while surfing the Internet. ABout 90-minutes later the wife get’s up and comes and checks on me.
She decides to take a look at the thermometer and its reading a little about 35ºC, which is 95ºF. Yessir, there is a reason why I have a small shop fan on and ITS BECAUSE I WASN’T JOKING ABOUT THE DANG TEMPS IN THESE ROOMS! lol
So, 74ºF in the master bedroom meets 95ºF in a room not more than 10-12′ walking distance, and both rooms getting the morning sun. Now the funny part: The AC vent (in the ceiling) is closed in the master bedroom, but not the master bath. Vent in computer room is never closed.
Her reaction was not only priceless, but I think it actually hit home in her. Nice!

so what?
Check duck sizing, and install a zoning system.
watch out for those undersized ducks!!!!!!
it's the oversized ducks that'll lay an egg on ya when yer not looking...;)
Welcome to the Taunton University of Knowledge FHB Campus at Breaktime. where ... Excellence is its own reward!
Was the door shut in this room that got hot? What is the undercut on the door? Where is the return(s) for that part of the house. How much heat do you think your computers generate? Can you turn on your computer without turning other peferal devices such as printer(s)?
How hot was the coffee?
Read Hube's reply again. DanT
I think you identified the problem:
..."and begin gulping my quart of hot coffee"...
Substitute whiskey and the heat, differences in thrmometer readings and nagging of the wife will seem less an issue. At the very least fortifying the coffee should take the edge off.
You can also practice the mechanisc's shrug and vacuous 'yes dear'.
Combine these in some combination and your well on your way to a happy dotage.
Doesn't anyone teach these things any more? Used to be men learned these things in the bowling league or 'poker night' with the boys. You really need to get out more. Consult with your peers. Compare notes. The women certainly do. Your falling behind and it's pinching your style.
So, you think the coffee and computers were sufficient to easily drive a closed room's temp in 90-mintes to +20 degrees above thermostat setting? BTW, there is 1/4" gap between the top of the carpet and the bottom of the door. The return in the room is located on the ceiling at the door.
I'm acknowledging that the closed-door plus two computers and a large coffee (and one fat man, lol) can do this kind of temperature increase, but I found it amusing to illustrate to the wife exactly how hot it can get in this room. She now can understand how this relates to the other converted bedroom with the CRT projector and AV components with the same duct/return setup (and closed door).

Well, let's look at some numbers.
We had a person in the room, that's good for 300 btu/hr sensible (and another 300 latent). I'm remembering that an "average" computer is about 300 btu/hr as well. So, you have the heat input of three people in that room.
That's before any solar gain, etc. With the room closed, there's no "blending" either, not until the a/c kicks on, and adds cooler air to the room.
My reflex is to suggest a louvered door, but that won't help move heated air out of the room (and won't be much noise control, either). That makes me wonder if maybe what's needed is a fan unit in the return air duct. If you could circulate the heated air to the rest of the house, that does two things. First, it's moving the hot air. Second, by recirulating the air, the temp near to the stat is more likely to 'change' and kick the a/c on.Occupational hazard of my occupation not being around (sorry Bubba)
