Hi,

One of my clients is moving offices and the office they are moving into has no aircon, but does has a hole in the wall to stick a pipe out of.

Does anyone have some suggestions on effecient aircon units? the room is about 2m wide 3.5 tall and 3 deep so its not massive.

Many thanks
 
Besides the hot air outlet, don't forget that air-cons extract condensate (water). Cheaper units collect to a tank which needs regular emptying or the unit will switch itself off (I've seen machines which were full after 4 hrs in some conditions). Ideally get a machine that expels this through the hot-air hose otherwise with a pumped water hose; last choice is a gravity water hose but you'll need to raise the machine higher than the hole.

Curious why you want portable not external or wallmount split-unit? These are much quieter and more efficient as they have comparatively loads of cool-air available for the radiator.

For sensible recommendations you'll need to estimate how may kW/BTUs of cooling you want, based not just on volume but also equipment and any sun-facing windows.

Agree. Portable units are complete crap and only of use in an emergency. We had four of them for a while and having the water changed every day (sometimes more often) was a nightmare. FYI, if the water fills they turn off, so its not like you cant deal with it.
 
Given where the thread was posted, I was a little concerned that OP might be planning to cool a server room where there probably won't be anyone present to see the unit switch off. I'm assuming portables don't support sending "tank full" SNMP traps :D

I recall a cash-strapped school who thought they'd get by using a portable instead of paying for repairs to the proper external units in one of their server rooms. After a month of Summer the compressor sounded like a jackhammer. Initially a technician was scheduled to empty water daily, but there was much unhappyness when the servers overheated and shut themelves down for protection, during a hot and humid weekend because the aircon tank got full and switched off. Their solution... raise the aircon on a table and have it drain to a larger bucket underneath :p
 
Well basically theres 3 servers no windows and a hole in the wall. The problem is that the buildings rented and hte landlord wont let me put a 2 part unit and have a bit hanging from the wall.... so not a lot i can do. I have seen some units that have draining hoses so i was thinking that i can have the unit high up and then lead the water hose out the same hole as the hot air?
 
Sounds like your screwed but at least you know the issues. I'd think about renting rather than buying too. We found they broke down so often it was good to make it someone elses issue, but we did have 5x 10k btu portables.
