Completion of server room air conditioning project for Ace Fire And Security Bedford (13/08/13)
Orion air conditioning has completed the installation of a replacement server room air conditioning unit for Ace Fire And Security in their head office in Bedford, Bedfordshire. The existing wall mounted air conditioning unit had failed due to old age, it was installed in 2003 and had worked continuously without any major issues since installation. Mitsubishi Heavy Industries air Conditioning is known for long reliable life and are ideal for server rooms and COM's rooms were a failure can mean the complete shut down of an entire business. The old air conditioning unit was on fixed speed system which switches on and off according to the thermostat. The new unit is a energy efficient inverter system which has a high COP and modulated inverter compressor which can save up to 40% on server room air conditioning that will run 24 hours / 7 days a week.
What server room air conditioning system was installed in Ace Fire And Security Bedford: 1 x Mitsubishi Heavy Industrial - SRK25ZJ-S1 Wall Mounted (2.5kW 12000 Btu) INVERTER Air Conditioning unit which provided enough cooling for the 4 meter square area in the server room. These units have a improved COP for a standard inverter (3.66 initial input) which means that every 1000w of electrical energy going in produces 3660 watts of cooling. Server room air
conditioning efficiency and CO2 emissions: This
server room air conditioning system took around 5 minutes to cool fully
but once cool the outdoor inverter units slowed down because the
temperature had been reached therefore just pumping small amounts
of cooling in to maintain the server room.
Summery: Server room
efficiency: 85% Total power of
servers: 1200 Watts Total heat loss:
180 Watts @85% efficiency Room in Square
Meters: 1800 Watts Total Heat Load:
400 Watts 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
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. We offer a complete
service to IT Managers, Building Managers and Server Room / Computer /
COMS room managers. Call us for a comprehensive quotation on
varied air conditioning manufactures to suit any budget on new
installations. We have worked with many Blue-chip organisations in
helping them develop their server room air conditioning. Contact Us:Sales Installation and Service
