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
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
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.
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.
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.
for server room air conditioning Mitsubishi, Daikin, Fujitsu,
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
portable air conditioning maybe your only
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.
