    Heat Problem

    I am trying to get some specs on some Dell Monitors and how much heat they would generate. I have a small office with 4 people working in there that are complaining about it's always hot in there. We have 7 computers that run 24/7 in a room about 14' x 24'. How can I figure out how much heat is being generated by the computers and 2 HP printers.

    I don't suppose you could turn everything off for 24 hours, take the temperature, and calculate the difference... but I'm not sure how you can calculate this otherwise. I don't think it's something that vendors publish in the spec sheets.

    If it isn't listed under the specifications in the user's manual, the manufacturer can supply the details. Try emailing their help desk.

    Ya might want to turn on the Air Conditioning, Scrooge. <img src=/S/cheers.gif border=0 alt=cheers width=30 height=16> Just Kidding.
    Or on a more serious side though ,ya might consider turning the temp down on the Air,,, Happy employees make for better profits. And by the way,Computers them selfs put off a lot of heat, thats why most IT places have Huge Air Conditioners cooling the rooms with the servers.
    My computer room is the hottest room in the house at all times. And your only allowing 48 SF or 384 Cubic Ft per Computer in that room of yours, thats like having a computer in a 7x7x8 room closed up. Not good temp wise. Heat wise, thats like working in a closet.

    Re: Heat Problem

    Will after some research last night I came up with the following information. Did you know that 1 person generates 400 BTU's an hour. 1 Watt = 3.412 BTU's per hour.
    This is an example I found on how to get a number. If you hvae 2 PC's with 300 watts power supplies per unit and no monitor the formula is the following:

    2 * (2 * 300) * 1.33 * 3.41 = 5456 BTUs

    1.33 is for the Power Supply effenciy ( no power supply is 100%. Also to add the heat from the net work cards, video card, CD drive, hard drives etc.
    3.41 = conversion from watts to BTU.

    Re: Heat Problem

    So the answer is, a bigger Room or, more Air Transfer, correct?

    The answer is......
    Management to open the pocket book and let us buy an A/C unit. And we all know how generous Management is.!

    Re: Heat Problem

    Seriously.......
    These are just a few notes that I put together on the Heat being generated in the Control Rm.. alone. This does not include the office I am in.

    4 works = 400 BTU/hour generated = 1,600 BTU/hour
    6 computers = 8,163.54 BTU/hour
    6 monitors = 2, 993.29 BTU/hour
    2 HP Printers (about) = 3,864.07 BTU/hour

    This is a total of about 16,620.80 BTU/hour of heat. A 2-ton AC unit cools 12,000 BTU's so we would need at least a 3-ton unit if we don't expect to add more equipment or bodies.

    Re: Heat Problem

    Just to add a little human interest to this post.
    I live in Houston, Tx and as you know we are getting ready for the BIG football game. This morning around 8:30am my youngest daughter called to let me know that she had been selected by her Principle (will four other kids also) to be able to attend a private practice with one of the teams. And as her father I can attended to practice session if I wanted to go. Like I would turn it down? Afterwards the kids/parents will have a small party to allow the kids to meet the players.

    With any kind of luck.. I can say the six words every kid interested in football wants to say to a Professional football player... GO OUT FOR A LONG PASS!

    Re: Heat Problem

    A quick browse on the HP web site shows that they publish power consumption for their monitors, but I couldn't see anything for the printers.

    Power consumption is of course almost exactly equal to heat output.

    It's an opportunity to take advantage of the efficiencies of co-generation: They can heat the rest of the building by exchanging the hot air from your room with the cool air in the rest of the building. It's win-win-win.

    Go Houston Go Houston Go Go!!!! <img src=/S/bananas.gif border=0 alt=bananas width=33 height=35> <img src=/S/bananas.gif border=0 alt=bananas width=33 height=35> <img src=/S/bananas.gif border=0 alt=bananas width=33 height=35>
    I was born and raised there (over 30 years) and all three of my children were born there too. My wife is a Yankee (Minnesota) but I know God has forgiven me! <img src=/S/angel.gif border=0 alt=angel width=15 height=21>
    I also ran an Appliance Business (with Window A/C's) and hung out with A/C guys.
    Houston used to be the "Air conditioning capital of the world" I don't know if it is still true.
    I was down visiting family for Christmas and saw all of the billboards for the Superbowl and thought, sure wait until I move!
    Anyway let us know if you get the A/C or if I can recommed (or not recommend) an A/C installer.
