  In FIG. 1, a primary side circuit 6 is configured by sequentially connecting a primary side blower 2a, a heating device 1, a drying chamber 3 for storing an object to be dried 4, and a high humidity side flow path 8 of a dehumidifying device 7. The secondary side circuit 9 is configured by connecting the secondary side blower 2b, the low temperature side of the heat exchanger 5, the low humidity side flow path 10 of the dehumidifying device 7, and the high temperature side of the heat exchanger 5, and the dehumidifying device 7 has a high humidity. The side flow path 8 and the low-humidity side flow path 10 are configured by partitioning with a moisture permeable film 11 such as an electrolyte membrane.

  About the dehumidification drying apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the air in the primary circuit 6 is sent to the heating device 1 by the primary blower 2a and heated, and then sent to the drying chamber 3 to contact the material to be dried 4 to absorb moisture, and then the dehumidifier 7 It sends to the wet side channel 8.

  At this time, since the air in the high-humidity side channel 8 of the dehumidifier 7 absorbs moisture, the water vapor partial pressure is high, and the low-humidity side channel 10 has the same absolute humidity as the outside air, so the water vapor partial pressure is low. Since the water vapor partial pressure on both sides of the moisture permeable membrane 11 is different, the moisture moves from the high-humidity side channel 8 to the low-humidity side channel 10. The air exiting the low-humidity side channel 10 dissipates heat in the heat exchanger 5 and heats the introduced outside air and then releases it to the outside. Therefore, the air in the high-humidity side channel 8 of the dehumidifier 7 and the low-humidity side channel 10 The temperature difference of air becomes small and the energy consumption of the heating apparatus 1 is significantly reduced.

  The larger the contact air amount, the more moisture can be taken out from the material 4 to be dried. The smaller the flow rate, the higher the temperature in the heat exchanger 5, so the air flow rate in the primary circuit 6 is increased. By setting the air flow rate of the secondary circuit 9 small, energy consumption can be further reduced and the drying time can be shortened.

Accordingly, the air flow rate of the primary side fan 12a and the secondary side fan 12b is controlled.

Since 12 is provided at the outlet of the low-humidity side flow path 10, the low-humidity side flow path 10 has the lowest pressure in the secondary circuit 9. Since the pressure difference between both sides of the moisture permeable membrane 11 of the dehumidifying device 7 becomes the largest, the amount of moisture moving from the high-humidity side channel 8 to the low-humidity side channel 10 can be maximized.
