A/C temperatures

[Bahceliboy5]

I must be a thicko (no comments please).I thought that by setting the unit at a low level.say 18/20 it would be cold which it is. However a friend advised that if you set it at say 25/7 it would still be cold and he his correct. Assuming 25/27 equals something like 80 f + that's warm so why is it still cold air coming from my a/c unit.

I am presuming the temp set on the aircon is the temp you want in the room. So if for example the temp in the room is 38C and you set aircon to 27C then it will throw out cold air until the room temp has dropped to 27C the same as that set on the aircon.

Makes sense to me.

Of course some aircon units are just not man enough to bring the temp down - often they cannot throw out enough cold air as they are to small/less powerful.

I am sure someone will come along with a more technical answer.

Seems a logical answer,thanks PD.

The temperature you set on the remote has nothing to do with the temperature of air coming out of the unit only the point at which the unit will automatically switch off.

The temperature you set on the remote has nothing to do with the temperature of air coming out of the unit only the point at which the unit will automatically switch off.

therefore it is always a good idea to put it 25/26 in the summer and 22/23 in the winter which saves electric and more importantly straining the machine. as we were told no machine will get the room to 16 and if it did you would be freezing.

We updated our air con this year to an inverter unit which we have set at 28 or 29 degrees with the fan on the lowest setting and it is lovely and cool. We even have to put a blanket over the dog as he finds it too cool!!

Also don't have two A/C units close together.
If they are set to different temps (even slightly out) they will 'fight' each other

My friend gave me a quick formula to work out what the setting should be. Outside temperature divided by 2 then add 10. Set your air con to that temperature. It works very well for me. Examples 35(outside temp) / 2 = 17.5 + 10 = 27.5. 40/2=20+10=30

When you have your aircon set to cool a room (as opposed to heating it) make sure that the outlet vents are pointing up as much as possible, not downwards. THe cold air will then naturally disperse throughout the room, rather than engulfing you in an icy blast...

If you have the airflow directed downwards, then the lower part of the room will fill up with cold air, and the temperature higher up, where the a/c unit (and the thermostat) is situated will remain warm - consequently, there will be a very long delay before the thermostat either turns off or reduces the flow of cold air, and in the meantime, the dog will freeze!

Some modern a/c units have a facility on the remote control for monitoring the actual air temperature at the same height as the people in the room, so that's worth playing about with - AFTER you've read the instructions, of course

p.s. just seen kedikat's post - I've never come across that before, looks interesting!
