> An air conditioner already is a cooler and a dehumidifier. The cold heat exchanger coil can cause condensation, which dehumidifies, but if the air temperature is 'correct' the AC control thermometer will keep the AC unit off. So you can have have an 'uncomfortable' environment because the temperature is 22C/70F but the humidity is >70%. This is why separate (whole house) dehumidifiers are often recommended: they have a separate hygrometers that cause the unit to start, regardless of what the temperature is.
