Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower for processing a thermal load near a window in a room and improving a thermal environment in the room.

[0002]

2. Description of the Related Art The outer walls and windows of a conventional building such as a building directly facing the outside cause an increase in the heat load in a living room due to direct sunlight or a cold outside temperature. That is, in summer, the cooling load of the living room increases due to the flow and radiation of heat from the outer wall, the radiation from the windows, and the like. Further, in winter, the air in contact with the outer wall and the window facing the room is cooled to generate cold draft, thereby increasing the heating load of the room. Such an increase in the heat load caused by the outer walls and windows of the building is a major problem such as an increase in the cost of cooling and heating in a building or the like having many windows with a large area covered with glass.

[0003] Such a peripheral portion of the window on the living room side is also called a perimeter zone. As a technology for treating the heat load in the perimeter zone, for example, Japanese Patent Publication No. 2659513 discloses a technology in which a fan coil unit is installed under a window. I have. In this way, even if the fan coil unit has a smaller blowing width than the opening of the window, the air conditioning airflow is formed along the entire surface of the window by connecting the blowing chamber, thereby preventing cold draft and dew condensation.

In Japanese Patent Publication No. 2-14616, a blower is installed on a floor near a window on a living room side, and air-conditioned air in the room is blown by a blower along a window surface on the living room side. 1 shows an air conditioner that blows air toward a ceiling. As described above, forming a curtain flow by room air along a window surface or a wall surface is very effective and effective for processing the heat load in the perimeter zone.

[0005]

However, when an air-conditioning airflow blowout chamber is provided between a blower and a blowout port as disclosed in Japanese Patent Publication No. 2659513, the equipment becomes large-scale due to heat insulation treatment and the like, and the initial condition of the air conditioner is increased. There is a problem of increasing costs. In addition, from the viewpoint of air conditioning and heating capacity, it is common to arrange a fan coil unit between pillars and one span of the pillar, and if the fan coil units are arranged in all windows, the initial cost of the air conditioner is reduced. Extremely increase.

[0006] On the other hand, in Japanese Patent Publication No. 2-14616, the initial cost can be reduced as compared with the fan coil system because one blower is installed for one window, but the window width differs depending on the building, and thus the window width varies depending on the building. The air volume and blade width required for a cross flow fan per sheet will also vary. The length of the cross-flow impeller is limited by the manufacturing method, and it is difficult to adjust the air volume and dimensions to the window width.Therefore, the portion that does not match the length is usually cross-flowed by a fan-shaped connecting duct called a hopper. The width of the blown airflow from the blower is increased to correspond to the window width. For this reason, the number of parts for installation increases, the initial cost other than the blower is high, and the workability is poor.

In both Japanese Patent Publication No. 2659513 and Japanese Patent Publication No. 2-14616, when the airflow is widened, a uniform airflow cannot be obtained unless proper rectification is performed for each connection chamber or hopper shape. In addition, there is a problem that the size of the apparatus for the connection chamber and the hopper becomes large, and it is difficult to introduce the system into a building employing windows or the like from the floor due to design problems.

Further, the sirocco fan and the cross-flow fan used in Japanese Patent Publication No. 2659513 and Japanese Patent Publication No. 2-14616 consume a large amount of power as a fan type, and this air conditioning system uses fans as many as the number of windows. And the running cost is high.

Further, even if an air flow outlet is provided on the window side, a beam or the like of a building is actually projected and obstructs the window. Therefore, a method such as providing a louver at the outlet or making the connection duct substantially crank-shaped is used. However, since the outlet is made to approach the window even a little, there is a problem that the initial cost of the apparatus is increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to construct a window without passing through a connection chamber or a hopper and to generate a uniform blown air flow. It does not require louvers to adjust the direction of the air flow, it is easy to install, power saving,
An object of the present invention is to obtain a compact air-conditioning blower having a low initial cost and running cost.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Embodiment 1 of the present invention will be described. The present embodiment is an apparatus that generates a curtain-shaped blown airflow 8 having a uniform wind speed in a longitudinal direction from a floor to a ceiling by using an axial blower in a perimeter zone on a living room side of an outer wall or a glass window. FIG. 1 is a perspective view of a blower, and a blower 10 is for reducing heat load by blowing air to a perimeter zone which is an outer wall of a building directly facing the outside and a perimeter zone on a living room side of a glass window. It is.

FIG. 2 shows the installation and use situation. For example, the air conditioner is installed at the lower part of the window 1 so that the room air 7 is shaped like a curtain having a uniform wind speed in the longitudinal direction from the floor to the ceiling along the window surface on the living room side. It is generated as a blown airflow 8. Above the ceiling of the living room, the airflow 8 that has taken the heat of the windows 1 and the blinds 3 is sucked,
An exhaust blower 6 is provided to exhaust heat to the outside of the room to perform heat load processing.

In the figure, a blower 10 is provided with a small, efficient, low power consumption axial flow blower as a blowing means in a chamber, and a uniform curtain-shaped airflow 8 with a small variation in wind speed in the longitudinal direction of the chamber. To generate. As shown in FIG. 1, an axial blower as a blower is a propeller type fan 12 rotated by a motor 11.
Is provided at the opening end 13a of the elongated chamber 13 having one end open and the other end closed so as to blow air into the chamber 13.

The chamber 13 is formed by winding a thin steel plate in an elongated cylinder. A slit-shaped outlet 14 having a narrow width in the longitudinal direction and a long length in the axial direction is provided on an outer peripheral surface between both ends of the cylinder. The cylindrical chamber 13 has a length of about 1 m, and a motor 11 on which an impeller 12 is mounted is fixed to one open end 13a via a motor mounting foot 15 with screws, and the other open end is provided. 13b is closed by a cover 16.

The motor mounting feet 15 have three feet fixed to the outer diameter of the motor 11. The outer circumference of the three feet has a circumferential surface configured to match the inner diameter of the chamber 13 and is fastened with screws. On the side surface in the longitudinal direction (axial direction) of the chamber 13, a slit-shaped outlet 14 which is an opening having a width of about 5 to 40 mm except for a part where the impeller 12 is provided is provided in parallel with the outer diameter of the chamber. I have. The outlet 14 may be formed by arranging a large number of round or square holes in a line in the longitudinal direction in addition to the slit shape. The cover 16 has a cap shape including a cylindrical portion that fits into the outer diameter of the chamber 13 and an end face that closes one end of the cylindrical portion. It is fixed by screwing to the diameter.

When the blower 10 constructed as described above is turned on and operated, the motor 11 and the fan 1 are turned on.
2 is rotated to blow air, and air is sent into the chamber 13. Since the end of the chamber 13 on the side opposite to the fan is closed by the cover 16 so that air does not leak, the energy of the blown air changes from dynamic pressure to static pressure inside the chamber 13. Due to the static pressure that has risen inside the chamber 13, a blowout airflow 17 that has little variation in the wind speed in the longitudinal direction and is substantially perpendicular to the axis of the chamber is generated from the slit-shaped blowout port 14 provided on the side surface. . The blowout airflow 17 becomes a thin and wide curtain-like airflow according to the shape of the blowout port 14.

FIG. 3 shows that the width of the outlet 14 is reduced as the distance from the fan 12 is increased to adjust the outlet pressure loss.
This is an example of a blowing structure for making the pressure inside the chamber 13 uniform. FIG. 4 shows a structural example in which the pressure inside the chamber 13 is made uniform in the longitudinal direction by increasing the pressure loss of the outlet 14 by providing a narrow protruding nozzle 18 at the outlet 14.

In either structure, the dynamic pressure of the blown air is more effectively changed to a static pressure so that the blowing air velocity in the longitudinal direction is more uniform, substantially perpendicular to the axial direction of the chamber 13, and It can be generated as a thin and wide curtain-shaped blowing airflow 17 having a long cross section in the longitudinal direction of the chamber. Further, as shown in FIG. 3, the shape of the chamber 13 may be a hexahedron having a square air path cross section.
However, in this case, an orifice 20 is provided at the open end of the chamber 13 to prevent the backflow of air from the space at the corner of the chamber 13 on the outer periphery of the fan 12 and to increase the static pressure inside the chamber 13. Structure.

Embodiment 2 Embodiment 2 will be described with reference to FIG. In this embodiment, a blower provided with a fan and a motor on a cylindrical wind tunnel is provided at an opening of a chamber. In the figure, a blower 10 is a uniform curtain-shaped airflow 8 having a small variation in wind speed by a small-sized axial flow blower, which is efficient and has low power consumption as a blowing means.
In this configuration, a blower 25 having a propeller-type fan 12 rotated by a motor 11 is connected to one end of an elongated chamber 13 having one end closed.

The blower 25 as a blowing means has a motor 11 in a cylindrical wind tunnel 25c having one end opened as a suction portion 25a and the other end opened as a blowout portion 25b. Blowout part 2

When the air blower thus configured is operated with the switch turned on, the motor 11 and the fan 12 rotate to blow air, and air is sent into the chamber 13. Since one end of the chamber 13 is closed by the cover 16, the energy of the blown air changes from dynamic pressure to static pressure inside the chamber 13. Chamber 1
3, the force of the static pressure that has risen inside causes the slit-shaped outlet 14 provided on the side surface to have a small variation in the wind speed in the longitudinal direction and to extend in the direction substantially perpendicular to the axial direction of the chamber and to extend in the longitudinal direction of the chamber. It can be generated as a curtain-shaped blowing airflow 17 having a thin and wide cross section.

The air is blown from the outlet 14 in a direction substantially perpendicular to the axial direction of the chamber 13 as a curtain-shaped blown airflow 17 having a thin cross section and a wide width that is long in the longitudinal direction of the chamber.

Further, the chamber 13 is similar to that of the third embodiment.
When the current plate 19 is provided inside, a more uniform and vertical blown airflow 17 is obtained. As described in the first embodiment, since the blowout airflow 17 of about 1 m can be obtained for each fan 12, the length of the chamber 13 can be reduced to about 2 m by this configuration in which the fans 12 are arranged at both ends. Further, when the partition plate 27 is provided at the center of the chamber 13 as shown in FIG. 12, the phenomenon that the collision position of the airflow 26 is unstablely changed due to the rotation variation of the left and right impellers 12 can be prevented, and the stable blowing can be performed.

The blowout angle can be easily adjusted and changed by loosening the nut and changing the tightening position of the angle fixing screw 32f.

In the figure, reference numeral 36 denotes an extendable connection duct which connects the outlet 4a of the design cover 4 and guides the air flow from the blower to blow out from the outlet 4a of the design cover. It has an air passage area having substantially the same cross-sectional area as the outlet 14 of the blower. The present embodiment has a bellows structure that can be extended and contracted.

The configuration other than this is the same as that of the first embodiment, and the description of the same parts as those of the first embodiment will be omitted. In cold regions where the outside air temperature is low, dew condensation may occur when the indoor air-conditioned airflow 8 is blown onto windows. In the present embodiment, the temperature of the blown air flow 17 is raised and is made to follow the window surface, thereby raising the window surface temperature and preventing dew condensation.

The air pushed into the chamber 13 is heated by the electric heater 37 and is blown out from the outlet 14 as warm air. The blown air flow 17 flows along the window surface and raises the temperature of the window surface. In winter, when the window surface temperature becomes lower than the outdoor temperature due to outside air, dew condensation occurs. However, the window surface temperature can be raised to the outdoor temperature or higher. Also, as shown in FIG. 20, a similar effect can be obtained by disposing a planar heating element 38 on the inner surface of the chamber 13 instead of the rod-shaped electric heater 37. Similar effects can be obtained by using hot water, steam, or the like in addition to electric energy as a heat source.
