Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a drying device used in a drying room in a cold region.

(Prior Art) A drying device with good thermal efficiency for use in a drying room in a cold region has not yet been developed.

(Problems to be Solved by the Invention) An object of the present invention is to solve the above-mentioned conventional problems and provide a drying device with good thermal efficiency for use in a drying room in a cold region.

(Example) The drying apparatus of the present invention will be described below according to an example shown in the drawings.

FIG. 1 shows a drying device of the present invention, which is indoor A.
Intake path +1 connected to outdoor B and equipped with fan (2)
).

A dehumidification chamber (3) is provided in the air intake path (1), and an air/water separator (4) such as a wire mesh is attached to the dehumidification chamber (3).

Further, the drain in the dehumidification chamber (3) can be discharged through a drain path (5).

Furthermore, a heater (7) such as an electric heater or a hot water heater is installed in the intake path +1+ downstream of the dehumidification chamber (3).

On the other hand, an exhaust path (11) connecting indoor A and outdoor B is provided with a fan (12) attached thereto.

The exhaust path (river) is connected to the dehumidification chamber (3) by a connecting path (I3) in the middle.

In the illustrated embodiment, a pumper (14) is installed to adjust the branched flow rate flowing into the connection path (13).

The operation of the drying apparatus of the present invention shown in the above embodiments will be explained next.

In other words, the fan t2) (12) is driven to open the intake passage (1).
) to create an intake flow and an exhaust flow to the exhaust path (11), respectively.

As a result, the low-temperature dry air outdoors B is sucked into the air intake path fl+ and flows into the dehumidification chamber (3).

On the other hand, the high-temperature multi-component air in the room A is sucked into the exhaust passage (11), a part of which is discharged outdoors B, and the rest is passed through the connection passage (13).
and flows into the dehumidification chamber (3).

That is, the low temperature dry air from the outdoor B and the high temperature humid air from the indoor A are mixed in the dehumidifying room (3).

As a result, the temperature of the air in the room A decreases, and the water vapor contained therein condenses and comes into contact with the steam/water separator (4) in the dehumidifying chamber (3) and is separated.

The apparent heat accompanying the temperature drop of the air from indoor A and the latent heat of condensation accompanying the condensation of water vapor are transferred to the air from outdoor B, raising its temperature.

As a result of the above, in the dehumidifying room (3), the heat contained in the exhaust flow from indoor A is transferred to the intake air flow from outdoor B, and heat recovery is performed.

Next, the intake flow (where the exhaust flow is also mixed) is the heater (7).
It is then heated and supplied to the room.

Further, water droplets adhering to the air-water separator (4) in the dehumidifying chamber (3) accumulate at the bottom and are then discharged through the drain passage (5).

(Effects of the Invention) The embodiments of the drying apparatus of the present invention are as described above, and the effects thereof are listed below.

+1i The drying device of the present invention has the structure described in the claims, and has good thermal efficiency, especially since heat is recovered between the exhaust air flow and the intake air flow in the dehumidification chamber.

(2) The drying device of the present invention has the same configuration as above, and in particular, the exhaust air flow mixed with the intake air flow is dehumidified in the dehumidification chamber and returned to the room, so that sufficient drying can be achieved.
