PURPOSE:To enable a room to be kept at its comfortable state and in a clean hot air environment by a method wherein a regenerative dehumidifier and an air cooler are disposed in an air supply passage communicating from a surrounding air inlet port to an air supply plenum chamber, the air cooler is constructed by an evaporator of a heat pump device and then a condensing heat of the heat pump device is utilized as a regenerating heat source for the dehumidifier. CONSTITUTION:An entire floor surface of an air conditioned room 1 is made of a porous plate 2, and an under-floor spacing of the porous floor is formed into an air supplying plenum chamber 4. An entire surface of a ceiling of the room 1 is made of a porous plate 6 and then a garret spacing of the porous ceiling is formed at an air discharging plenum chamber 7. Supplied air controlled to an indoor set temperature is fed into the air supplying plenum chamber 4, thereby the air is supplied from the entire surface of the porous floor at a uniform low air speed and then the indoor air is discharged into the air discharging plenum chamber through the porous ceiling. In this case, a regenerative dehumidifier 22 and the air cooler 14 are disposed in the air supplying passage communicating from the surrounding air inlet port 10 with the air supplying plenum chamber 4. A refrigerant pipe is disposed between the air cooler 14 in a dehumidifying passage A and a condenser 24 in a regenerating passage B so as to form a heat pump. Then, the air cooler 14 is constructed by an evaporator in the heat pump device and at the same time a condensing heat of the heat pump is utilized as a regenerating heat source for the dehumidifier 22. |
