Abstract: A humidity control apparatus is provided with two adsorbing elements. The humidity control apparatus alternately repeats a first operation for dehumidifying air in the first adsorbing element while regenerating the second adsorbing element and a second operation for dehumidifying air in the second adsorbing element while regenerating the first adsorbing element. The second air taken into the humidity control apparatus is formed of a mixture of room air and outside air. In the humidity control apparatus, a mixture ratio between the room air and the outside air in the second air is variable.

Abstract: An air conditioning apparatus is provided with an adsorption element having a humidity adjusting side passageway configured to adsorb and desorb moisture by passage of adsorption air or regeneration air and a cooling side passageway through which cooling air passes so that the adsorption air is cooled by absorption of heat of adsorption generated during the adsorption in the humidity adjusting side passageway. In the air conditioning apparatus, air is humidified or dehumidified in the humidity adjusting side passageway of the adsorption element and is supplied to an indoor space. In order to achieve improvements in the cooling efficiency when cooling adsorption air by the use of cooling air in the cooling side passageway, room air, conditioned air, or mixed air which is a combination of room air and outdoor air is used as cooling air which is forced to flow through the adsorption element.

Abstract: Disclosed is an air conditioning apparatus which is provided with two adsorption elements (81, 82). The air conditioning apparatus repeats in alternation an operation in which the second adsorption element (82) is regenerated and, at the same time, air is dehumidified by the first adsorption element (81), and an operation in which the first adsorption element (81) is regenerated and, at same time, air is dehumidified by the second adsorption element (82). Additionally, the air conditioning apparatus includes a refrigerant circuit. The refrigerant circuit performs a refrigeration cycle in which a regenerative heat exchanger (92) operates as a condenser and a first cooling heat exchanger (93) or a second cooling heat exchanger (94) operates as an evaporator. For example, air, which has robbed heat of adsorption in the first adsorption element (81), is further heated by the regenerative heat exchanger (92) and is introduced into the second adsorption element (82).

Abstract: A tornado type air intake and blowing device has an exhaust port communicating with an exhaust duct, an air supply chamber which is provided so as to surround the exhaust port and to which air is supplied through an air supply inlet, and air blowing ports blowing air supplied into the air supply chamber by swirling the air from the outer periphery of the exhaust port diagonally downward, the air blowing ports being provided in a side wall part of the air supply chamber, whereby the exhaust port can be formed in the entire area of the lower opening surface of the air supply chamber, the outside diameter of the air supply chamber is sufficient if it is equal to an outside diameter corresponding to the required opening diameter of the exhaust port and, accordingly, a device body can be formed compact.

Abstract: A suction and exhaust device wherein air is supplied as air curtain flow through air outlet (3) while the air surrounded by the air curtain flow is sucked through suction ports (2b) to be exhausted. A supply space in the device is divided into two chambers, upper and lower, by a partition plate (41): a first supply air space (4c) on the upper side into which air from the supply air duct (5) is introduced and a second supply air space (4d) which spreads in the direction of the air outlet (3). The first and second supply air spaces (4c, 4d) are communicated with each other through annular flow equalizing channel (40R, 50R) of small channel diameter vertically extending in the outer periphery of the suction duct (3). This uniformalizes the flow rate distribution of the supply air flow from the air outlet and forms a stabilized air curtain flow.

Abstract: An air intake and blowing device, comprising a blowing fan (11) such as a turbo fan capable of blowing air in all directions which is installed inside a main casing (2) provided with an air intake port (5) and an air blowing port (9) enclosing the air intake port (5), the air blowing port (9) being provided with a vortex flow creating member which creates a spiral blowing vortex air flow to form a spirally swirl-blowing air flow, and air surrounded by the blowing air flow being formed in a stable tornado flow and sucked strongly into the air intake port (5).
