Re: Aircon add Humidity??
An aircon unit will ALWAYS dry the air and reduce humidity, hence why they always have either a drip tray or a vent hose to the exterior. However, once the compressir has done its job and cuts out leaving the unit to circulate the cooled air, the humidity in the machine can then be vented back into the space it's in.
This effect is more obvious in a car which is a smaller space, if you rech the desired temp and switch to 'econ' in the car after the aircon has been running, you'll often find the windscreen starts to mist up right away for the same reason.
So, it's not 'adding' humidity, it's just putting back what it's just taken out.
