Further, in a dehumidifying air conditioner using a dehumidifying rotor carrying a moisture adsorbent, it is necessary to lower the temperature raised by the adsorption of moisture by exchanging heat with indoor air. For this reason, a combination of a dehumidifying rotor and a sensible heat exchange rotor has been developed. In the combination of the dehumidifying rotor and the sensible heat exchange rotor, the sensible heat exchange efficiency is not 100% if the sensible heat is simply exchanged between the dry air whose temperature has risen by adsorption and the indoor air.

For this reason, water is sprayed into the return air from the room to lower the temperature of the return air below the room temperature, and the sensible heat is exchanged between the humid air and the dry air, which have decreased in temperature, for drying. It was designed to generate low-temperature air and supply it to the room. However, this structure has a problem that the air is mixed between the humid air and the dry air, and the air whose humidity has been lowered is humidified.
