It is difficult to promote the adsorption of moisture to the adsorbent. Further, the amount of heat of adsorption in the adsorbent decreases as the amount of moisture in the air decreases. Therefore, on the downstream side of the adsorption heat exchanger, the adsorbent is excessively cooled by the endothermic action of the refrigerant.
  • the adsorption block at the position downstream of the adsorption heat exchanger functioning as an evaporator (the position where the air dehumidified and cooled by the adsorption heat exchanger passes), the adsorption heat exchanger Since the contact area between the air and the adsorbent can be increased on the downstream side, the dehumidifying ability of the dehumidifying device (10) can be effectively improved as compared with the case of increasing the size of the adsorption heat exchanger.
  • the adsorbent regeneration operation release of moisture from the adsorbent into the air
  • the adsorbent adsorption operation adsorption of moisture from the air into the adsorbent.
  • the air volume of the air passing through the heat exchange chamber (S11, S12) provided with the adsorption heat exchanger (101, 102) serving as an evaporator among the first and second heat exchange chambers (S11, S12) is:
  • the amount of air passing through the heat exchange chamber (S12, S11) provided with the adsorption heat exchanger (102, 101) serving as a condenser may be larger or the same.
  • the temperature of the air supplied to the regeneration passage (P2) (that is, the air supplied to the heat exchange chamber (S12, S11) provided with the adsorption heat exchanger (102, 101) serving as a condenser) is Higher than the temperature of the air supplied to the supply passage (P1) (that is, the air supplied to the heat exchange chamber (S11, S12) provided with the adsorption heat exchanger (101, 102) serving as an evaporator)
  • a predetermined temperature difference specifically, a temperature difference at which the adsorbent can be regenerated
  • the above dehumidifying apparatus is useful as a dehumidifying apparatus for dehumidifying a humidity control space such as a dry clean room.

Abstract

Selon l'invention, des premier et second échangeurs de chaleur par adsorption (101, 102) sont respectivement agencés dans des première et seconde chambres d'échange de chaleur (S11, S12) et sont chacun commutés afin de servir d'évaporateur et de condenseur. Un premier bloc d'adsorption (301) est agencé à l'intérieur de la première chambre d'échange de chaleur (S11) en aval du premier échangeur de chaleur par adsorption (101) lorsque le premier échangeur de chaleur par adsorption (101) a été commuté pour servir d'évaporateur et le second bloc d'adsorption (302) est agencé à l'intérieur de la seconde chambre d'échange de chaleur (S12) en aval du second échangeur de chaleur par adsorption (102) lorsque le second échangeur de chaleur par adsorption (102) a été commuté afin de servir d'évaporateur. Du fait de la configuration ci-dessus, un dispositif de déshumidification peut atteindre une haute performance de déshumidification alors qu'une augmentation de la consommation électrique est réduite au minimum.
