Ideal room air temperature for data center
(OP)
does anybody know what should be the ideal room air temperature a cooling system has to keep in a data center in order to avoid a computer equipment damage ?
I would appreciate very much a promtly reply.

Here are usual spec:
Air conditioning equipment must be capable of producing recommended design conditions of 72°F plus or minus 21/2°F dry bulb and 48 plus or minus 5% relative humidity and function within operational limits of 68°F to 78°F dry bulb and 40% to 60% relative humidity. To meet system availability and flexibility requirements, equipment must provide complete control 24 hrs per day, seven days per week.

Table 1 Typical Computer Room Design Conditions
Condition Recommended Level
Temperature control range 22ºC ± 1ºC
Relative humidity control range 50 ± 5%
Filtration quality(b) 45%, min. 20%
These conditions are typical of those recommended by most computer equipment manufacturers.
(b)From ASHRAE Standard 52.1 dust-spot efficiency test.
Table 2 Design Conditions for Air Supply Direct to Computer Equipment
Condition Recommended Level
Temperature As required for heat dissipation
Relative humidity Maximum 65
Filtration quality 45% minimum

Data centre's are energy beast's,
from past experience, operating costs
in the end will probably drive the end
user to increase the db temp. to try
and save energy.
Data centres that were orginially
designed (as mentioned by ercanbaser) for
21 deg C, 50% - and were subsquently modified
with the approval of the data equipment
manufacturer, for 26 deg C db - saving millions
of dollars per year.
Don't forget that ashrae guide is not engraved
in stone, there are only guidelines. Choose
your conditions carefully to suit your
application.
In your case it may not be possible to
adopt a higher design, engineering is
a creative endeavour, don't let fixed
ashrae guideline dictate your design.
at the end of the day the owner will
thank you.
cheers,
