In the exhaust air duct 35 provided in the floor-type desiccant-type ventilation fan 1, a return air filter 34 for collecting dust in the indoor air is provided in the vicinity of the return air duct connection port 33 in the outdoor direction. Then, after the sensible heat exchanger unit 11, the dehumidifying regenerator 14, and the desiccant dehumidifier unit 12 are provided in this order, the air in the second air passage is finally moved in the vicinity of the exhaust duct connection port 37. An exhaust air blower 36 is provided as a means for the above.

(Sensible heat exchanger unit)
Main functional parts of the floor-mounted desiccant ventilation fan 1 of the present invention will be described. In the sensible heat exchanger unit 11, two broadest opposing surfaces in a flat and substantially rectangular parallelepiped form air-transmitting surfaces. The portion through which air passes is a flat cylindrical shape that is rotated by a motor. The material of the portion through which air passes is a heat absorbing member that stores or releases sensible heat in the air when air is passed through. The two surfaces through which air passes are divided into two at the central portion by the partition plate 4, and one of the divided portions becomes the supply air passage 25 and the other becomes the exhaust air passage 35. When the room is heated, the heat absorbing member on the exhaust air passage 35 side of the portion through which the air of the sensible heat exchanger unit 11 passes absorbs heat from the warmed indoor air passing through the exhaust air passage 35. To store heat. The heat-absorbing heat-absorbing member is rotated by a motor and becomes a portion through which air of the sensible heat exchanger unit 11 on the supply air passage 25 side passes. Since the portion of the sensible heat exchanger unit 11 that has turned to the air supply air passage 25 is made to pass through the heat-absorbing member, the sensible heat that is stored by the heat-absorbing member is passed through when the cold outside air is passed through it. Will be taken away and will be warmed. As described above, the sensible heat of the indoor air flowing through the exhaust air passage 35 is moved to the outside air passing through the air supply air passage 25 and returned to the room again. Thereby, during heating, the room can be ventilated without impairing the room heating effect. On the contrary, during the cooling, the outside air flowing through the supply air passage 25 passes through the sensible heat exchanger unit 11, so that the outside air is deprived of sensible heat by the cooled indoor air flowing through the exhaust air passage 35, and ventilation. Since the temperature of the outside air sometimes supplied is cooled, the room can be ventilated without impairing the cooling efficiency.

(Desicant type dehumidifier unit)
The desiccant-type dehumidifier unit 12 is a flat, substantially rectangular parallelepiped, and two widest surfaces facing each other are surfaces through which air passes. The portion through which the air passes is a cylindrical shape with a flat shape, and an adsorbing element is provided inside, and is configured to be rotated by a motor. The adsorption element has a property of adsorbing or desorbing moisture in the air. The two surfaces through which air passes are divided into two at the central portion, and one of the divided portions serves as the supply air passage 25 and the other serves as the exhaust air passage 35. When the outside air passing through the air supply passage 25 passes through the desiccant-type dehumidifier unit 12, moisture in the outside air is adsorbed by the adsorbing element and exhibits a dehumidifying function. The adsorption element that adsorbs moisture by rotating a flat cylindrical portion through which air passes by a motor desorbs moisture from the indoor air passing through the exhaust air passage 35. At this time, since the release of moisture from the adsorbing element is insufficient only with the indoor air, the dehumidifying regenerator 14 is provided upstream of the desiccant-type dehumidifier unit 12 in the exhaust air passage 35, and the exhaust air passage 35 is connected to the exhaust air passage 35. Heating the indoor air passing therethrough makes it possible to more effectively desorb moisture from the adsorption element. Thereby, the moisture entering from the outside is reduced, and the room can be dehumidified by exhausting it together with air containing moisture in the room.
Further, the dehumidifying regenerator 14 is configured to heat the air passing therethrough by a heat exchanger incorporating an electric heating element, a heat pump heat exchanger, a heat exchanger that receives supply of a heat medium from an external heat source device, or the like. ing.
