- lukevp 4y agoRelative humidity rises for the same volume of water/air as temperature decreases. The dryness of an A/C is because of the condensation accumulating from the air passed across the evaporator, it is dehumidifying at the same time it’s cooling.
- b112 4y agoIf that was the case, it would be more humid, not less.
- SoftTalker 4y agoThe air tempertature at the evaporator is cold -- maybe 40 degrees or so? The relative humidity is about 100% (as evidenced by liquid water condensing on it). But the house itself never gets that cold, heat moves in from outside by radiation, the air temperature is higher, maybe 70-80 degrees, which results in a lower relative humidity.
