Having designed Computer Rooms / Data Centers, golden rule was never to have the AirCon units facing each other, as the airflow across the room is effected, and the Temperature sensors in the units will shut the units down quicker, so you'll end up with a stop-start system, rather than a constantly running / comfort cooling system.

 

Quick question. Any reason why AirCon wasn't included in the original building design? Impact on aesthetics, electrical distribution, outdoor condenser placement etc. 

You have the most informed opinion concerning units facing each other affecting the sensors.IMHO as an old Marine Engineer.

You are far less likely to be disappointed with bigger than smaller...

Alternatively, fit a 24,000 BTU cassette unit in the middle of the room.

Didn't you previously say on another thread you'd recommend 18k BTU rather than 24k BTU due to the fan only being the difference? or maybe it was someone else.

 

On the subject of TCLs, any appropriate size inverter or is there a specific model you recommend?

Yes I did, but in wall mounted split units, cassettes are completely different. I don't recommend 24,000 BTU in wall mounted, they are noisy.

 

I have one 36.000 BTU single phase, heat/cool Fujitsu model.

We have installed 9,000, 12,000 & 18,000 BTU inverter models, they are all excellent.  They now have available units that connect to the internet.  We buy on Lazada, sometimes waiting for the price to drop if they raise them artificially prior to a sale.
