Did I make the right decision choosing Air conditioner for my room?
A larger air conditioning unit can pull the temperature in the room down too fast and not dehumidify which will make the room feel muggy. It does depend how over sized it is. 10 square meters is about 107 square feet. You should only need 4000 btu to cool that space on a 95 degree day with 50% humidity. I would say that a 5000 btu would be adequate, but you could go up to an 8000 btu if you wanted to. If you put in a 12000 btu or higher unit I would think that you may run into problems. A large unit uses more electricity by itself but can efficiently cool a larger area than 2 smaller units of equal rating. Cycling a larger unit on and off will burn extra electricity too. If the unit pull the room temp down and cycles off the room temp could go right back up within 20 minutes and the unit will have to cycle back on for 20 then off for 20. (These are just estimates for the sake of conversation) You may find that running a smaller unit with extended run cycles will give you better perform
