- the sensible heat exchanger 130 takes the form of a honeycomb-patterned disc fabricated by processing a thin plate, such as an aluminum plate, etc. suitable for heat exchange. There are provided an additional motor and belt (not shown) for rotation of the sensible heat exchanger 130.
- the heating coil 140 is located in the first wet channel 112-1 of the case 110 at a position between a rear end of the sensible heat exchanger 130 and the flow hole 114-1.

- the dehumidifying wheel 150 has a rotating shaft 151 installed in the same direction as the first partition 113, and takes the form of a disc to rotate about the rotating shaft 151 inside the first wet channel 112-1 and the dry channel 111 of the case 110.

- the air (9) is raised only in temperature while passing through the heating coil, resulting in high-temperature air ®.
- the air ® is dropped in temperature, but raised in absolute humidity in the course of passing through the dehumidifying wheel, thereby being changed to low-temperature and high-humidity air ⁇ . Then, while passing through the sensible heat exchanger in the second wet channel, the air @ is heat exchanged with the outside air (B) in the first wet channel such that the heat exchanged air ⁇ , which is slightly dropped in temperature but keeps the same absolute humidity as the air ⁇ , is discharged through the exhaust hole.
- the dehumidifying cooling device for district heating air to be supplied into a conditioning indoor space is subjected to the transfer of heat and moisture via a direct contact with the dehumidifying cooling device.
- This has the effect of achieving excellent transfer efficiency and producing and supplying cooling air with a low-temperature heating source of 60°C.
- the dehumidifying cooling device is operable in the atmospheric pressure state and has a simplified configuration, resulting in a considerable reduction of manufacturing costs. [Industrial Applicability]
- a dehumidifying and cooling device can be installed to residential and business buildings, etc. using hot water delivered by district heating facilities, so as to utilize the hot water as a source for cooling a room.
