Eli5 how dry mode works in air conditioner in difference to cool mode?
In: 1
If an ac offers “dry mode”, most likely it is to function as a dehumidifier rather than to cool the air. However, there are 2 distinct possibilities that distinguish AC units from actual dehumidifiers:
(1) A dehumidifier has a *humidistat* rather than a thermostat. So it runs based on the measured humidity of the air, rather than the temperature. An AC in “dry mode” may or may not have a humidistat.
(2) A dehumidifier prevents the air from becoming too cold, by having the air flow against both the evaporator and condenser parts of the loop. An AC is not normally designed to do this, it’s designed to have the evaporator in the indoor part and the condenser in the outdoor part. So it might not be possible to route the air over the condenser to warm it back up after cooling it.
