On AC units, why is 20°C on cold mode colder than 20°C on warm mode? Why isn’t it the same temperature?
In: Technology
The thermostat is a destination not a throttle
If its currently 25C in your room and you set it to 20C the AC will blow out air that is the same temperature as if you set it to 18C or any other number below 25, and it’ll keep blowing that cool air until it reaches 20C and then it will stop.
If you set it to warm instead it will blow out warm/hot air until it reaches the target temperature and then it’ll stop
If your AC unit blew air that was 20C when the room is 25C it’ll take *forever* to cool the room down, and it’ll never get to the 20C you requested so its generally cooling the air down towards 10-15C and blowing that out.
You are setting the temperature you’d like it to be in *the room* and the AC unit will adjust its output until the room gets to that temperature, you are *not* setting the temperature of the *AC unit*
