Condensate Issues on
Server Room Air
Conditioning In Cold Conditions
Server room air conditioning will
run 24 hours a day seven days a week to cool the ambient air.
This means that on certain days of the year the outside
temperature is colder than the server room. I.e if a server room
has a required temperature of 19DegC and the outside air
temperature is -2DegC. This can throw up issues with the system
if this is not planned into the initial installation. A common
problem is that condensate water which is collected from the
server room can freeze up in the condensate pipe in gravity
The condensate pipe of choice for
drain line is 22mm overflow pipe or braided 10mm/12mm which has
no insulation properties and when exposed to freezing weather
conditions with already chilled water coming off a indoor
evaporator coil can freeze in long runs of the braided hose.
This causes the indoor unit to leak as the pipe gets more
restricted and as the ice builds up in the pipe. I have seen
insulation around condensate pipe to inhibit the effects of the
Cold weather plays havoc with server room air conditioning
Drain lines get blocked in server room air conditioning systems
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.
