Completion
of server room air conditioning project for Fibrefab 2012
Orion
air conditioning and refrigeration limited has completed the
installation of a replacement server room air conditioning
unit for Fibrefab in Haverhill. The existing wall mounted air
conditioning unit had failed due to old age, it was installed
in 1999 and had worked continuously without any major issues
since installation. Mitsubishi Electric air Conditioning is
renowned for long reliable life and are ideal for server rooms
and coms rooms were a failure can mean the complete shut down
of an entire business. The old air conditioning unit was on
R22 refrigerant which is banned for use in the UK as from
2015. 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
air conditioning unit was installed in FibreFab:
1
x Mitsubishi
Heavy Industrial - SRK63ZE-S1 Wall Mounted (6.3kW 21000 Btu)
HYPER-INVERTER Air
Conditioning units
which provided enough cooling for the 5 meter area in the
server room. These units have a amazing COP (3.65 initial
input on SRK63ZE) which means that every 1000w of electrical
energy going in produces 3650 watts of cooling.
Server
room air conditioning efficiency and CO2 emissions:
This
air conditioning system, because slightly oversized for the
area took around 10 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: 5000 Watts
Total
heat loss: 750 Watts@85%
Room
in Square Meters: 1800 Watts
Total
Heat Load: 2550 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.
