Description

  The present invention relates to a cold air generator used to cool outdoor warm air and blow it toward the room, and in particular, a livestock building such as a factory, a poultry house, a pig house, a cow house, or a plastic house, etc. The present invention relates to a cold wind generator for cooling a building such as a horticultural building.

  Conventionally, an air conditioner is most commonly used to cool outdoor air and send it indoors. Also, in order to reduce manufacturing, maintenance and operation costs, a breathable impregnated cloth is stretched on the front of the blower fan at right angles to the air feeding direction, and this impregnated cloth is constantly wetted with cold water. There is also a raindrop-shaped water curtain formed in front of the blower.

  There is also known a cold air blower in which a compressor, a condenser, an evaporator, and a capillary are provided on a frame body to form an integral type. This cold air compressor compresses the refrigerant with a compressor, the pressurized refrigerant dissipates heat and liquefies by a condenser, and in the evaporator where the liquid refrigerant is sent through the capillaries, the refrigerant absorbs heat and vaporizes, and the refrigerant turned into gas It is pressurized again by the compressor and circulates. And the air which passes by a condenser becomes high temperature, is discharged | emitted by an exhaust fan, the air which passes an evaporator is cooled, and it blows off by a cold wind fan (for example, patent document 1).

  This cool air blower uses cool air blown out from the front of the frame, and by installing a swing louver at the cold air outlet, the wind direction is swung left and right to create cold air in the same way as the neck vibration of the fan. Can do. However, since hot air is blown out from the exhaust outlet at the back of the frame, this hot air may be mixed in with the air that becomes cold air, and sufficient cold air may not be obtained. For this reason, it is recommended that the cool air blower outlet be directed to the outside so that hot air does not accumulate, or that the air blow duct be attached to the cool air blower outlet near the outside to guide the hot air to the outside. It has been broken.

  Also, if the roof or walls of buildings such as manufacturing factories are poorly insulated, the temperature inside the building may become abnormally high due to the effects of solar radiation, especially in the summer, and the work efficiency and safety of workers may be greatly reduced. is there. For this reason, there is an indoor ventilation system that cools the air in the building, but conventionally, water is sprayed from the top onto the cooling element of the cooling unit installed on one wall or window, and the air flowing from the outside air by the latent heat of water evaporation The temperature was lowered, cold air was sent into the building, and the air that passed through the building was discharged from the ceiling or the other window (for example, see Patent Document 2).

  However, livestock structures such as factories, poultry houses, pig houses, cowsheds, or horticultural structures such as plastic houses are large in capacity and generally poorly sealed. Equipment costs and operating costs are significantly increased in order to be reduced by the air conditioner. In addition, a device that forms a raindrop-like water curtain on the front surface of the blower requires a large apparatus and consumes a large amount of water and energy. In the latter case, since the cooling of warm outside air is mainly performed by heat exchange with cold water, the effect of generating cooling is low as compared with the energy used and the amount of water. However, at this time, a part of the water is vaporized and the heat of the outside air is taken away. However, the cooling effect as a whole is very small as compared with the heat exchange with the cold water.

  Furthermore, according to the latter, the humidity of the generated cold air rises considerably, so that it cannot be applied depending on the application, and it is difficult to say that those who receive this cold are necessarily comfortable. is there. In view of the above-described conventional problems, the present invention provides a cold air generator that effectively blows outdoor warm air into the room by heat of vaporization of water without exchanging heat with cold water. It is intended.

  For this reason, in the cold air generating device of the present invention, the water pipe arranged on the front surface of the opened blower frame is provided with a spray nozzle for generating fine fog, and a vertically long swing louver swinging left and right is provided in the opening. It is characterized by arranging a plurality of sheets.

Since the present invention is configured as described above, the following excellent effects are obtained.
(1) The fine mist ejected forward from the spray nozzle is sufficiently vaporized by the air sent from the blower, and the air is effectively cooled by the heat of vaporization.
(2) Since the latent heat accompanying the vaporization of water is used, even if the temperature of the water supplied to the water supply pipe is not necessarily low, the outside air can be effectively cooled to obtain cold air.
(3) By swinging the louver, fine mist sprayed from the spray nozzle can be dispersed in a wide angle in the left-right direction.

  Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings. 1 is a perspective view showing an embodiment of a cold air generator according to the present invention, FIG. 2 is a front view, FIG. 3 is a side view of FIG. 2, and FIG. 4 is a perspective view of a main part showing a base end portion of a louver. 5 is a perspective view of a main part showing a rotating cam link portion.

  As shown in FIGS. 1 to 3, the cold air generator 1 of the present invention includes a blower 3 for introducing outside air into a room and a spray device 5. The back side of the blower 3 is open to the outside of the room, and a spray device 5 is attached in front of the fan 4.

  The spraying device 5 is attached to the front surface of the blower 3 with a water supply hose 8 whose front end is closed and a tap water supply pipe is connected to the base end so as to be orthogonal to the air blowing direction. A plurality of spray nozzles 9 are mounted with their discharge ports on the front side.

  The spraying device 5 is fastened and fixed to a long bolt by a resin band at a facing edge portion orthogonal to the blowing direction on the front side of the rectangular frame 2 of the blower 3. In addition, the water supply hose 8 is not necessarily one, and a plurality of water supply hoses 8 may be arranged so as to intersect or be arranged. Further, it is desirable that the spray nozzle 9 is capable of changing the particle size of the fine mist to be ejected by screwing the cap in the discharge portion and changing the ejection speed and the ejection angle.

  The air outlet of the frame 2 is vertically defined in a lattice shape by a swing louver 6, and the upper and lower ends thereof are swingably attached to the frame 2 by a movable link 7. A swing louver 6 is installed in the opening of the frame 2, and a motor 10 is attached to the frame 2 above the swing louver 6 to drive the swing louver 6.

  In the apparatus of the above-described embodiment, the pressure water is supplied after adjusting the discharge part of the spray nozzle 9 so that the particle size of the fine mist to be ejected becomes as small as possible, and the ejection speed and the ejection angle become preferable values. While feeding into the hose 8, the fan 4 of the blower 3 is rotated. Then, the fine mist W ejected from the spray nozzle 9 spreads to the front surface of the blower 3, and the outside air sucked and discharged by the blower 3 is blown onto the fine mist W. Therefore, the outside air is forcibly mixed with the fine mist to completely vaporize all the fine mist, and the outside air is blown into the room after the temperature is rapidly lowered by the latent heat.

  As shown in FIGS. 4 to 5, when the motor 10 rotates, the cam 10a provided at the lower end of the motor shaft rotates, and the swing louver 6 swings left and right via the cam link 7a. At this time, the wind of the fan 4 changes the blowing direction to the left and right as in the swinging operation of the fan. That is, the spray W changes in the left-right direction according to the left-right movement of the swing louver 1.

  With the above configuration, the fine mist W ejected from the spraying device 5 is diffused in a wide angle in the left-right direction and can efficiently cool the room.
