Shing L,

As stated in a previous response:

Energy enters the server and so it has to leave the server either in the form of heat, motion or potential energy (electricity). Since very little electricity leaves the server down the Ethernet cable and none at all in the case of fiber optics, 100% of the energy is eventually converted to heat or motion. In the case of motion, this is wind (fans used to dissapate heat) or sound. Even the sound will eventually become heat as the energy is absorbed by surrounding materials.. It is true that some energy may escape in the form of sound or air motion, but this amount is minimal. Spinning hard drives will store some energy as momentum, but the bearings are very efficient so once the energy is spent to spin them, very little is required to maintain the rotation as some is lost to heat and friction in the bearings.

The calculation assume all power convert to heat, which is wrong. A server system draws most of the power to circuitry and fan. That cannot be all considered as heat. Watt to BTU can only be directly converted for device exclusively for heating.

If in case i dont the instrument watt ratings. and i have to find out the dissipation of that instrument.is there any practical method to find out the dissipation if we dont the waatage rating of that instrument.plz help me out by replying on above mail addresss

Praveen,
In common usage 12,000 BTU/h is considered a Ton.

I want to calculate the amount of heat dissipated by a 1 ton Air conditioner per hour ? how to calculate it ?

how much amount of heat is generated from a single server(computer) and how much amount of heat can be generated from it…?

i have a question
how much amount of heat is released from the server(computer)and how much amount of eletricity can be produced from it

@sunil
The first law of thermodynamics essentially states that energy cannot be created or destroyed (conservation of energy).

Computer work is an abstract term to describe the switching on and off of transistors and logic controllers within the chips.

Energy enters the server and so it has to leave the server either in the form of heat, motion or potential energy (electricity). Since very little electricity leaves the server down the Ethernet cable and none at all in the case of fiber optics, 100% of the energy is eventually converted to heat or motion (sound). If the room is sound proof, even the sound will eventually become heat. Spinning hard drives will store some energy as momentum, but the bearings are very efficient so once the energy is spent to spin them, very little is required to maintain the rotation as some is lost to heat and friction in the bearings.

In the example of the server with a 1000 W power supply, even if the sever is working at full load, all of that 1000 W would not be converted into heat. Most of the power would be used by the server actually to do its work. How would you factor this for your cooling capacity calculation?
