Server Room Cooling Specs

By mtorres7 ·
Our server room is 4 feet wide and 7 feet long. We have 2 dual processor servers, 3 24 port-switches and 2 PCs (call accounting and security cameras software).
I need advice for cooling requirements, specially during weekends and night time. Is it neccesary to keep the room "cooled" all the time? Is it enought to mantain on an extractor during non-working hours?

From a purely logical point of view I would say the room needed to be cooled at all times. Witha thermostat the amount of cooling will be automatically provided in order to maintain a constant(ish) temperature.

An over heated server isnt going to be any better off just because nobody is there using it, if anything you wont notice the problem until something physically fails and then you'll have a great Monday morning to look forward to.

If its on it needs cooling, how much will depend as much on the temperature outside as on the inside, hot sunny days=hotter server room etc.

Computer rooms are to be kept at 68 to 72 degrees with a relative humidity of 40 to 50%.

A room that is stagnent in air circulation can go up in tempature with only a 100 watt lightbulb.

If a you or a tech go into that room while equipment is on and breaks out in a sweat after 10 minutes the room is bad for the electronics.

The Cooling needs to be constant. Monitors for the temp and humidity should be in the room.

Whatever you need to do the maintain the 68 to 72 temp and 40 to 50% humidity.

What you need to remember is that the humidity takes longer to bring down than the temp.

The cooling can be a big trade off. First you
could use a small air conditioning unit and hope
fully vent outside, otherwise you'll have to deal with the condensation that will generated
by the AC unit. second with out knowing any
of you're pesent temperature ranges and not
just daily but yearly extremes, sometimes
simple placement of insulation and ventilation
will be all thats needed for that little room.

Well firstly the room is small so a lot of the generated heat from the computers will heat up the room quite nicely. Even better than a 100 Watt Light Bulb constantly switched on. You could walk into a burnt out mess first thing on a Monday Mourning after the place has been all locked up for security and there has been no air flow over the week end.

On the up side it is a small room so you don't need a big Air Con unit but you'll need either access to the outside for a refrigerated AC unit which will remove humidity from the air or a ducted AC Unit into the room. As you haven't mentioned where exactly this room is it could be very important as to how you keep it to a reasonable temp. If it is well underground you obviously can not have anything but ducted AC. But if it is on ground level all you need is a small Thermostat controlled refrigerated AC unit and just set the temp to what you require to keep the room cool and leave it be.
