Need help with a Heat Load Study

[cross6]

We've been having problems with our AC systems in our building.

I'm a network engineer - but I'm halfway done with an EE - I haven't taken any thermo.

So I need to figure roughly what is the heat load or dissipation of typical pc's, laser printers, etc etc.

Now I can measure the typical current consumption - and if I knew what % of that went to heat - then I would have a good idea...

How should I go about this?

Conact the vendors of said components and ask if they have the BTU values for them. Often they will for calculating A/C for racking and so forth.

Most stuff (if not all) should have its power usage on it somewhere. As for what percentage gets lost as heat, that depends on each device really. A good general ballpark figure is probably 50%.

Edit: FWIW, posting the same topic to more than one section (OT and HT) is generally frowned upon.

Are you certain?

Oh sorry.



Isn't that power rating on devices the max?
