Server room cooling load rule of thumb
A quick rule of thumb air conditioner calculation for a room is to determine the floor area of the room in terms of the Width by the Depth in metres and to multiply this by 20 to give a British Thermal Unit (BTU) for the space. If the space is 10 by 20 metres, the floor area = 10 × 20 = 200m² The BTU is 200 × 20 = 4,000 BTU … See more Most electronic devices can operate up to 30-40˚C and server brochures and datasheet specifications may state that their devices can work up to this temperature range … See more How to cool servers within an IT closest, computer or server room depends on their arrangement and installation format.

Server room cooling load rule of thumb
Did you know?
WebThe same room might have six CRAC units, each rated at 20 tons on the nameplate. The actual cooling delivered by each unit depends on a number of factors (most notably return air temperature). So, we need another rule-of-thumb: assume the actual capacity is 70% of the rated capacity. For the six units combined, the result is 84 tons of cooling. WebThe general rule of thumb formula is: 12,000 BTUs per hour per 1 ton of cooling The number of watts is written on the back of the power supply (and in the server's technical specs). …
