To provide a moisture conditioning device using a refrigerating cycle for regenerating adsorbing materials and cooling air, having improved moisture conditioning performance by shortening a time after operation change-over in a refrigerant circuit but before the adsorbing materials start sufficient adsorption/desorption of moisture.
In the refrigerant circuit of the moisture conditioning device 10, the adsorbing materials are supported on the surfaces of first and second heat exchangers 61, 62. In the refrigerant circuit, the direction of circulating refrigerant is changeable over by the operation of a four-way valve. The moisture conditioning device 10 uses the heat exchangers 61, 62 as evaporators for dehumidifying first air and uses the heat exchangers 61, 62 as condensers for humidifying second air. When the temperature of the second air is higher than that of the first air, an air distribution passage is changed over before operation change-over in the refrigerant circuit. Conversely, when the temperature of the first air is higher than that of the second air, the air distribution passage is changed over after the operation change-over in the refrigerant circuit.
