Default Cooling Needs!!!

How does one determine the cooling needs if a datacenter, Does it has some relation with the average power consumption of the data center?

Perhaps it does. You can always do the most obvious approach. Check the temperature. If it's still hot, you need to cool it more. I guess you can monitor the heat and humidity at key areas in the data center.

My rule of thumb is power in = heat out. 1 kW = 3412 BTUs. Sure, some mechanical work is done by spinning disks and fans, but mostly data centers are filled with machines that move electrons around, generating heat.

If you know the total power consumption of the entire datacenter, or just individual racks, a rule of thumb is, that approximately 80% of the power consumed is transferred into heatloss. In reality it's a little less than 80%, but then you're on the safe side when designing your cooling solution.

I've been researching this recently. A good pair of whitepapers on this topic is available from APC:
Also, APC has some simple web-based "Trade-Off Tools" for data center planning, energy saving, virtualization effects, etc.

Just work out the sum of heat given out.

A fraction of the power consumption is given off as heat energy, so a cooler about double the amount of heat given off, around 30%, should do fine.

The measure for determining cooling need in data centers is kilowatts per rack, and cubic feet per minute per kilowatt. By figuring out how much power your server cabinet is drawing, the logic goes that you’ll then know how much cooling you need.

Optimize power and cooling requirements Consolidated environments require less energy to power and cool than an entire room, or possibly multiple rooms, of unconsolidated physical servers.

Yeah, as Ken said power supply also generate some amount of heat.

You can check this link, to make better power supply assessment
