Computer Room Cooling System

I need to find a cooling solution for a small computer room. The building where the room is located shuts of the central AC in the summer and the room temperature goes up to around 95F - 100F. The quotes i got to install a separate AC unit in this room are around $40k. This is a bit much for my taste and i am looking for alternatives like AC cooled Rack. I am now to this and i am not sure where to start or what alternatives i have, any advise is appreciated.

do a google serach for wall mounted air conditioners  and look at the split units  be aware that it requires drainage  you can also look at portable ac units which are handy but i dont recommend.

Those kind of unit are not an option, the building code requires that it the AC is in the ceiling.

We actually just use a portable AC similar to below

I've never heard of a building code that says AC units must be in the ceiling.

I have one that is suspended from the deck, but there is no "ceiling".  If you mean that it must be vented into a common plenum space, you _can_ get units that are floor-mounted or on casters that have vent kits for a 2x2 or 2x4-foot drop ceiling grid.

You cannot use AC units that claim to have no drainage or no condensate bottle required.  These gather the condensate in a tube, then drip it onto the compressor motor housing so it ends up as hot water vapor in the exhaust stream.  You don't want to be blowing wet air into your plenum space.

What is the size of the room and the BTU output of the equipement?

@aleghart

That what i was told by the office manager. In case i am allowed to install a unit in the room which one would you recommend? The room is around 150 Square Foot, i don't know the exact BTU output, it should be in the 15.000 - 18.000 range.

I was looking at the HP Modular Cooling System racks, does anyone have experience  with those? What would be the Pro and Cons for a AC Unit vs. AC Rack?

Portability.  APC makes two portable units.  One is ~10-12k BTU, the other is larger.  Both have casters and can be re-purposes for spot cooling other areas.

Drain line is a smart idea for unattended operation.

For space-saving, we hung a 3-ton from the p
overhead.  It's grilles actually fit perfectly into a 2x4 ceiling grid, but we have a hard duct to the building's return plenum.
