If I put an air conditioner into one room, it will cool the other room, right?


No.

Not unless there are two points of ventilation joining the two rooms. EG: two doorways. The basic rule is that hot air is high pressure and cool air is low pressure.

High pressure will flow to low pressure every time.

This means that the hot air (high pressure in the room next door) will naturally ventilate to the low pressure, (the room with the air conditioner in it).

And here's the problem... The air conditioner is blowing air out the door way - and the velocity of this air will prevent the hot air from ventilating into the room with the air conditioner.

The hot air will be trapped at the point of juncture (the doorway) and the room without the air conditioner will stay hot.

"But what if I put a SUPER DUPER, EXTRA LARGE air conditioner into my room - surely it will have an effect on the other room?"

Unfortunately not. You will be wasting your time and money - and void your warranty.

An air conditioner which is too large for the room that it's in will not only cost more to buy, cost more to install, cost more to run - and it will not have ANY effect on the room next door.

"Hm. So how do I do this?"

In order to allow an air conditioner to air condition two rooms, you need ventilation (air movement). To create ventilation, you need two points where the air can be sent and received. (Two doorways, an internal window or a doorway which represents more than half of the width of the room).

By providing ventilation, this not only allows hot to travel to cold but it allows the positive pressure created by the air conditioner to ventilate into the adjacent room.

"HEY PRESTO, I've done it!"

This is what we like to hear. Air conditioning and ventilation are interesting topics - and something we like to talk about every day.
