- the water frozen on the surface of the adsorbent is heated by the refrigerant flowing through the adsorption heat exchange that becomes a condenser and gradually melts. If the water is repeatedly frozen and thawed on the surface of the adsorbent, As the adsorbent gradually deteriorates, the adsorbent may peel off due to the surface force of the adsorption heat exchanger.
- the present invention has been made in view of the strong point, and an object of the present invention is to provide extremely low temperature air during a regeneration operation in a humidity control apparatus having an adsorption heat exchanger carrying an adsorbent. It is to avoid that the condensed water freezes on the surface of the adsorbent when passing through the heat of adsorption.
- the first invention comprises a heat medium circuit (50) through which a heat medium flows, and an adsorption heat exchanger (51, 52) connected to the heat medium circuit (50) and carrying an adsorbent.
- the adsorbent of the heat exchanger ⁇ (51,52) is heated by the heat medium of the heat medium circuit (50), and the adsorbent and air are brought into contact with each other to release the moisture of the adsorbent to the air. It assumes a humidity control device that performs regenerative operations.
- the adsorption heat exchange (51, 52) of the humidity control apparatus is characterized in that air flows from the inflow side to the outflow side of the heat medium during the regeneration operation.

- the adsorbent of the adsorption heat exchanger (51, 52) is cooled with a heat medium, and the adsorbent and the air are brought into contact with each other to cause moisture in the air.
- the inflow side force of the heat medium is directed toward the outflow side during the adsorption operation, and air flows. It is a feature.
- a third invention is the method according to the first invention, wherein the adsorbent of the adsorption heat exchanger (51, 52) is cooled with a heat medium, and the adsorbent and air are brought into contact with each other to thereby remove moisture in the air.
- the outflow side force of the heat medium is directed toward the inflow side during the adsorption operation, and air flows. It is a feature.
- the heat medium circuit is constituted by a refrigerant circuit (50) that performs a refrigeration cycle by circulating the refrigerant. It is a feature.
- the adsorption heat exchanger (51, 52) is connected to the refrigerant circuit (50) as the heat medium circuit.
- the refrigerant is circulated and a refrigeration cycle is performed, so that the adsorption heat exchange (51, 52) functions as a condenser or an evaporator.
- the adsorbent heated by the refrigerant of adsorption heat exchange (51, 52) serving as a condenser and air come into contact with each other. As a result, the moisture adsorbed by the adsorbent is released to the air.
- the adsorbent cooled by the refrigerant of the adsorption heat exchanger (51, 52) serving as an evaporator and the air come into contact with each other. As a result, moisture in the air is adsorbed by the adsorbent.
- the present invention in the adsorption heat exchanger (51, 52) during the regeneration operation, air is circulated from the inflow side to the outflow side of the heat medium. Therefore, according to the present invention, it is possible to effectively raise the temperature of the air at the air inflow end of the adsorption heat exchange (51, 52). In this way, for example, even when extremely cold outdoor air passes through the adsorption heat exchanger (51, 52) in winter, the outdoor air is kept at a relatively high temperature at the air inflow end of the adsorption heat exchanger (51, 52). Can be degrees.
- the inflow side force of the heat medium is also directed toward the outflow side so that air flows. Therefore, according to the present invention, air can be effectively cooled at the air inflow end of the adsorption heat exchanger (51, 52). In this way, the air is dew pointed on the air inflow side of the adsorption heat exchanger (51, 52). This air can be dehumidified by condensing moisture below the temperature. For this reason, the dehumidification capability of this humidity control apparatus can be improved. Therefore, even when the dehumidifying ability of the adsorbent alone cannot sufficiently dehumidify the air, it is possible to make up for the lack of dehumidifying ability of the adsorbent by condensing moisture.

Therefore, according to the present invention, it is possible to improve the air cooling effect by the adsorption heat exchange (51, 52). Therefore, in the adsorption heat exchanger (51, 52) during the adsorption operation, the air can be effectively dehumidified without being cooled, and for example, the room can be effectively cooled during the dehumidification operation in summer. .
- the refrigerant circuit (50) that performs the refrigeration cycle is used as the heat medium circuit. Therefore, in the adsorption heat exchange (51, 52), the adsorbent can be effectively cooled by the evaporating refrigerant, and the adsorption capacity of the adsorbent can be improved. In addition, the adsorbent can be effectively heated by the condensing refrigerant, and the regeneration capacity of the adsorbent can be improved.
