  • the present invention relates to a humidifier which supplies a humidified air into a room, and an air conditioner using the humidifier.
  • a humidifier supplying a humidified air into a room from outside of the room is known.
  • moisture in the outside air is adsorbed onto an outdoor humidifying rotor and then desorbed from the humidifying rotor to humidify the air.

  • the humidifier is here described to facilitate understanding of the present invention, although it is not a known art nor a prior art.
  • the humidifier has a problem that in summer when the humidifying operation is not required, hot and humid outside air flows into the humidifying hose, so that when the indoor temperature is lower than the outside air temperature, or the temperature of the outside air, owing to cooling of the room, moisture condenses to form dew inside the humidifying hose at its indoor side and dewdrops stay there.
