Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a heating and cooling device for a greenhouse for plants, a cultivation room for mushrooms, etc., a livestock shed, or a residence.

(Prior Art) The inventors of the present invention first created a hollow fiber duct using a fiber mat made of fibers intertwined at random with gaps between them, and inside the fiber duct. We proposed a structure in which a heat dissipation pipe and a water discharge pipe with injection holes are installed in the fiber duct, and a blower for blowing air is connected to the fiber duct.In practice, this device is installed on the ground inside the greenhouse. I was using it. However, in reality, in the case of cooling, the cold air is heavy and stays in the lower part of the greenhouse, while in the case of heating, the warm air is lighter and moves to the upper part of the greenhouse, making it impossible to effectively cool or heat the entire greenhouse. It was hot.

(Problems to be Solved by the Invention) The object of the present invention is to provide an elevating type air-conditioning/heating device that can effectively cool and heat the entire room.

(Means for Solving the Problems) In order to achieve the above object, the present invention forms a hollow fiber duct using a fiber mat formed by randomly intertwining fibers at intervals, and inside the fiber duct. Regarding a heating and cooling device in which a heat dissipation pipe and a water discharge pipe having an injection hole are respectively arranged in the fiber duct and a blower for blowing air is connected to the fiber duct, the heating and cooling device is supported in a room so that it can be raised and lowered, and The structure is equipped with a drive device that raises and lowers the dual-use device. An example implemented in a greenhouse will be described below with reference to the drawings.

In Figures 1 and 2, long frames 2 and 2 are installed on both the left and right sides of a building in the greenhouse H, extending over the entire depth of the greenhouse.
are suspended by wires 3, 3, .

The structure of the above-mentioned heating and cooling device (hereinafter referred to as this device) 1 is as follows. In Figures 3 and 4, arch-shaped horizontal frame members 4 such as metal wires and straight vertical frame members 5...
A nearly tunnel-shaped frame 6 formed by bonding together is placed on the bottom plate of the gutter 7, and fibers such as synthetic fibers and natural fibers are randomly arranged at small intervals on the outer surface of the frame 6. A hollow fiber duct slightly shorter than the above-mentioned frame 2 is covered with a porous fiber mat 8 whose surface is irregularly uneven and which is formed by intertwining the fibers and bonding the intersections of each fiber with adhesive or welding if necessary. 9, and as an example of the fiber duct 9, cylindrical blower covers 11, 11 having a blower 10 inside are connected to both ends of the opening, respectively,
Inside the fiber duct 9, a U-shaped heat radiation pipe 12 and a water discharge pipe 13 having a large number of injection holes are arranged along the longitudinal direction of the duct, and both ends of the heat radiation pipe 12 are drawn out of the fiber duct 9. Also, one end of the water discharge pipe 13 is closed, and the other end is drawn out to the outside of the duct 9.

The above-mentioned pedestal 2 is constructed by connecting two support pipes 14, 14 with a large number of horizontal beams 15, as shown in FIG. It is suspended by passing through a hanging frame 16 suspended by....

The hanging frame 16 has one end of the arm 18 connected to one end of the U-shaped receiving part 17 by a hinge 28, and a hook 29 connected to the other end of the receiving part 17.
A support frame 20 of a pulley 19 is fixed to the intermediate portion of the arm 18.

An example of a drive device for raising and lowering the device 1 will be described next. In FIGS. 1 and 2, fixed pulleys 21 are placed above the support position of the apparatus 1 in the greenhouse at positions corresponding to the hanging frames 16 of the pedestal 2.
At the same time, the wires 3, whose one ends are fixed in the greenhouse, are hung on the pulleys 19 (moving pulleys) of the hanging frames 16 and the fixed pulleys 21, respectively, while the first, second, and sixth wires shown in the figures are attached. A long interlocking shaft 2 that spans the entire depth of the greenhouse is attached to the side wall of the greenhouse.
2 is rotatably supported horizontally by brackets 23, and the fixed pulley 21 is attached to the interlocking shaft 22.
The wire winding drums 24 are fixed at positions corresponding to the wire winding drums 24, respectively, and a gear box 27 is fixed to one side of the bracket 23 located at the outermost end. The meshing worms are supported, a manual handle 25 is attached to the shaft of the worms, and the wires 3 are wound from the fixed pulleys 21 through guide pulleys 26 to the winding drums 24, respectively.

The operation of this device will be explained next. To humidify and cool the greenhouse in the summer, turn the handle 25 to wind the wires 3 around each drum 24.
As a result, the device 1 is raised to the highest level, where the tips of the stretchable flexible ducts 30, 30 connected to the blower covers 11, 11 at both ends are brought out through the wall of the greenhouse H, and then released. When water is forced into the water pipe 13 and sprayed from each injection hole of the water discharge pipe, and air from outside the greenhouse is forced into the fiber duct 9 by starting the blowers 10, 10, the sprayed water is sprayed into the fiber mat 8. Fine water droplets adhere to each fiber, and on the other hand, the outside air blown into the fiber duct 9 passes through the gaps between the fibers of the fiber mat 8 and blows out from the entire surface of the mat 8, and at this time, the fine water droplets become blown out and air. The blown air is vaporized upon contact, and the blown air is cooled by the latent heat of vaporization and discharged to the outside as cold air.

When performing only air conditioning without humidification, instead of supplying water to the water discharge pipe 13, cold water is circulated through the heat radiation pipe 12, and the flexible ducts 30, 30
and blower covers 11, 11, and blower 1.
0,10 to transport the air inside the greenhouse to the fiber duct 9
Send it inside. In this way, heat exchange is performed on the surface of the heat dissipation tube 12, and at the same time, the airflow blown into the fiber duct hits the uneven inner surface of the fiber mat 8 and generates a turbulent vortex. This agitates the surface air layer of the heat dissipation tube 12 to reduce heat transfer resistance, thereby promoting the passage of cold heat from the heat dissipation tube 12 to the air in the fiber duct 9. The cooled air in the fiber duct 9 is then discharged to the outside through the fiber gaps.

Next, when performing heating in winter, after separating the flexible ducts 30, 30 and blower covers 11, 11, turn the handle 25 to rewind the wires 3 of the drums 24, thereby lowering the device 1 to the lowest position. There, hot water is circulated through the heat dissipation pipe 12 and indoor air is forced into the fiber duct 9 by the blowers 10, 10.
Heat exchange takes place on the surface of the fiber mat 8, and the heated air is discharged to the outside through the fiber gaps of the fiber mat 8.

In either case of cooling or heating as described above, when repairing the apparatus 1, the apparatus 1 is raised or lowered to a required height by turning the handle 25. Also, when the device 1 is kept stationary in a fixed position, the shadow of the device 1 is formed in the fixed position, so the handle 25
The shadow can be dispersed by moving the device 1 up and down as appropriate. Furthermore, the device 1 can be moved up and down as appropriate so that the device 1 does not interfere with the work, such as cultivation in a greenhouse.

The drive device for raising and lowering this device 1 may be an automatic type using a motor instead of the manual one in the above example, and one example is one in which the output shaft of a geared motor is connected to the interlocking shaft 22 in the above example. is obtained.

(Effect of the invention) According to the elevating type air-conditioning/heating device of the present invention, the driving device drives the air-conditioning/heating device upwards for cooling and downwards for heating, thereby effectively heating and cooling the entire room. Furthermore, by raising and lowering the air-conditioning/heating device as appropriate, it is possible to obtain conveniences such as easier repair work of this device, dispersion of the shadow of this device, and easier work such as cultivation. It is extremely effective in practice.
