Why
inverter air
conditioning
are a must for server room
With
server room air conditioning will run 24 hours / 7 days a week and the
power that can be used when servers are being used to their full
capacity. With the old fixed speed systems the inductive load spikes and
high current draw meant in badly constructed server rooms they could
actually cause issues with the servers they are there to cool.
After
a recent installation of a replacement server room air conditioning
system which was being run from a UPS system in case of power outages,
we found that the savings from having inverter systems was phenomenal.
The original systems were R22 and R407C refrigerant units and used on
average 36% of the 100Kva UPS system or 36A running. The new inverter
air conditioning systems when maintaining temperature at the same
ambient only populated 16% of the server rooms UPS system. That meant it
was drawing 16A in comparison to 36A with the old systems in the same
weather conditions. A saving of 44% on the companies energy bill.
Breaking
this down to cost, in the UK we pay £0.11p per kw/h for electricity.
The original systems at current electricity costs were costing £22.70 /
day. The new air conditioning system cost on average £10.13 / day to
run. Over the year the inverter air conditioning has saved the client
£4585.50.
With
a server room air conditioning systems having a life span of 5 to 15
years (depending on equipment) if you want to save a lot of electricity
make inverter air conditioning your priority.
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.
