How much cooling is needed for a data center?

Often, the cooling capacity required is about 1.3 times the expected IT load plus any redundant capacity, especially for smaller server rooms. The cooling load you calculate may differ from this though, especially if you operate a larger data center.

What is a rule of thumb tonnage of cooling for computer rooms?

Determining the critical heat load starts with the identification of the equipment to be deployed within the space. Additionally, the lighting, people, and heat conducted from the surrounding spaces will also contribute to the overall heat load.

How is server room cooling capacity calculated?

Add together all the wattages for Servers, Switches, Routers and multiply by 3.5. Take the total wattage of the lighting and multiply by 4.25. Add all the BTUs together. This is the amount of cooling required so you need one or more air conditioning units to handle that amount of heat.

How do you calculate heat and cooling load?

To calculate the estimated HVAC load for a house with 2,500 square feet, 12 windows, and 3 exterior doors occupied by 4 people, simply plug it into this formula: 2,500 x 25 = 62,500 base BTU. 4 people x 400 = 1,600. 12 windows x 1,000 = 12,000.

How do you calculate the size of a server room?

Measure the width and length of the room, and then multiply the two measurements to get the room’s square footage. Multiply the square footage by 337 to determine the room’s initial BTU needs. Determine the total BTUs for all the equipment used in the room.

How do I calculate BTU for server room cooling?

Useful BTU Cooling Formulae:

1. Equipment BTU = Total wattage for all equipment x 3.5.
2. Lighting BTU = Total wattage for all lighting x 4.25.
3. Total Occupant BTU = Number of occupants x 400.
4. Room Area BTU = Length (m) x Width (m) x 337.
5. Total Heat Load = Room Area BTU + Total Occupant BTU + Equipment BTU + Lighting BTU.
