Abstract

<P>PROBLEM TO BE SOLVED: To provide a desiccant air conditioner which produces air having extremely low humidity by using an adsorption type dehumidifying means, provides low-temperature supply air when a vaporizing-cooling means is combined with it, and then provides high-quality air even if the humidity of the outside air rises. <P>SOLUTION: The outside air is dehumidified by a first dehumidifying rotor 1. The temperature of the outside air A is lowered by carrying out sensible heat exchange between the air with temperature lowered by an evaporating cooler 17 and the dried air B with temperature raised by the dehumidification. The dried air C with temperature lowered is further dehumidified by a second dehumidifying rotor 10. The dried air D with temperature raised by the dehumidification is cooled by carrying out sensible heat exchange with the air in a room, and supplied into the room. <P>COPYRIGHT: (C)2003,JPO

いという問題がある。As described above, the conventional desiccant air conditioner can use hot water from a solar water heater or hot water from a waste heat source as a driving energy source, and does not use CFCs. However, there is a problem that the humidity of the supply air cannot be lowered so much when the humidity of the outside air is high, because the humidity of the supply air largely depends on the air condition of the outside air.
