Server room air conditioning

It is advised when purchasing air conditioning units for server rooms to have energy efficient inverter systems. Generally server room air conditioning will run 24 hours / 7 days a week  and the inverter will save energy and equipment failure. Generally cooling is only required but in the UK most air conditioning units are heat pumps which heat and cool. All server rooms and COMS equipment give off a lot of heat and need to be constantly cooled otherwise they could overheat and shut down causing major problems for businesses. Most fixed-speed air conditioning (non inverter) rarely come with a low ambient kit so if the temperature gets to cold outside then the indoor unit will not cool properly because the inside temperature is hotter than the outside, which is a common fault in UK winters. The cheaper air conditioning  units also have issues with parts so if your unit breaks down the part required may take weeks to source. That's why it is worth buying up to date systems to future proof your server room cooling.

Key points to think about when getting air conditioning for server rooms

• Use inverter air conditioning as it will save energy in the long run.

• Cheap air conditioning units do not work in cold weather because they do not have a outside fan speed controller (low ambient kit)

• Use a established brand so if a part fails on you Server room air conditioning you are not waiting 8 weeks for a part.

• Sometimes it is worth having two server room air conditioning units because if one fails you still have some cooling.

• To establish the heat load of you servers add up all the power supplies of your servers rack and assume a 40% loss to heat. i.e- If you have 10 servers with 400watt power supply the total watts will be 4000 watts. assuming a 40% loss the heat load will be 1600 watts.

• Work on a average watts per/Msq of 125watts, so if you server room is 5 x 5 meters you will require a base of 3.5kw/12000btu + the heat load.

• Advised manufactures for server room air conditioning Mitsubishi, Daikin, Fujitsu, Sanyo.

• Always use auto-restart units for server room air conditioning units as power failures can shut budget air conditioning down.

• If your server room is temporary (ie short term lease on building) or has building restrictions then Portable / Mobile air conditioning maybe your only option.

• If using portable air conditioning for your server room then make sure it recycles the water for better cooling performance of that it has a integral condensate pump.

• Use a established business who will not be going out of business for your server room air conditioning installation as the warranty of the air conditioning is with the supplier not the manufacturer.

Server room air conditioning case study:

A server room air conditioning unit using a fixed speed air conditioning units for a server room air conditioning which was in need of re-newel. We advised using a Mitsubishi Heavy Industrial - SRK71ZE-S1 Wall Mounted (7.1kW 24000 Btu) hyper inverter wall air conditioning unit which is a hyper efficient with a cat A energy product label and designed for continual use which many server room air conditioning units require. The old fixed speed units used a lot of energy because of the start current associated with inductive loads with fixed speed air conditioning.  The Mitsubishi Heavy Industrial - SRK71ZE-S1 Wall Mounted (7.1kW 24000 Btu) hyper inverter saved money in the long run and as it is designed for continual use will last.
