Description

Ductless Blowing System

The present invention is a factory, hall. It is a blowing system suitable for large-area buildings such as warehouses, underground parking lots, etc. It is used in combination with external devices (external air intake system forced exhaust system, air conditioner, etc.) installed in the building and easily A ductless blowing system for efficiently conveying and agitating air from a suction opening to a forced exhaust device, and conveying and agitating air-conditioned air generated from an air conditioner in a building without using a duct. will be.

Conventional blower systems used in the above-mentioned applications in combination with an external air intake device, forced exhaust device or air conditioner include: (1) pipe a duct to a required part of a ceiling part inside a building and convey airflow through the duct; (2) Generating high-speed air jets by combining an axial blower and a duct or a nozzle placed in the required part of the ceiling in the building (Special Office 63-33053), and ③ A downward angle can be adjusted to the required part of the ceiling part inside the building. Multiple axial blowers (special place No. 60-160922) or airflow generators having casings of approximately the same length as the sidewall gap between the left and right walls of the building (p. 4-125141) Is known.

However, there are the following problems in using the above-mentioned system in a building having a large area, i.e., the system of ① has a large duct pipe length, so that the blowing loss in the duct is large, so that the duct diameter and the blower are large. Therefore, there is a problem in that it is necessary to earn airflow, high running cost, and a large amount of space occupied by the duct. In addition, there is a problem that it is difficult to pipe a long duct into the building.

The system of (2) has a problem in that it is necessary to increase the blower size by making the blower large due to blowing loss in the duct, and the running cost is high. In addition, since the strength of the airflow is generated by the distance from the blower to the nozzle, and because the air is blown into a spot shape, a problem of uneven airflow is likely to occur due to mixing of the airflow, and it is difficult to maintain the balance of the airflow. There is also a problem of poor efficiency. In addition, there is a problem that the installation cost is high because parts such as ducts, nozzles, etc. increases.

The system of ③ uses axial blower, so the airflow becomes spot, so it is easy to cause uneven airflow, and in order to air-condition the whole building on average, it is necessary to install many axial blowers. There is a problem that the running coast is increased.

Since the casing of the airflow generator has a length almost equal to the distance between the left and right walls, the airflow can efficiently flow even when there is a large obstacle such as a vehicle in the parking lot. Since the length is almost equal to the distance between the left and right walls, installation is difficult and there is a problem in that the installation place is limited. In addition, there is a problem that the installation cost is high.

Accordingly, an object of the present invention is to provide an air blowing system which is easy to install and efficiently carries out air conveyance and stirring in a large building interior in view of the above-described problems, and has a low running cost.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described in detail based on drawing. In the ductless blower system of the present invention, depending on the purpose of ventilation, such as ventilation or air conditioning, or ventilation and air conditioning, for example, the external air in consideration of the installation position of external devices such as pseudo air intake, forced exhaust, and air conditioner A plurality of perfusion blowers are provided in an arrangement in which the air is agitated simultaneously with the return of air from an intake device or an opening for easily taking in outside air or from an air conditioner, and the air is efficiently blown inside the building.

That is, in the ductless blower system of the present invention, air flows from the plurality of flow-through blowers that blow the plurality of flow-through blowers in one or the same direction are blown in the same direction or the other one located in front or side of the flow-through blower. It is arranged to reach a plurality of the through-flow blower. For this reason, in the present invention, the blowing section is appropriately set in accordance with the internal structure of the building so that the above effects are effectively obtained for the plurality of through-flow blowers.

The blowing section in the ductless blowing system of the present invention creates a partition (space) of a predetermined area at the four boundary surfaces of the side which geometrically partitions the bottom surface and the ceiling surface and the space fitted to the floor surface and the ceiling surface, At least one said perfusion blower is provided inside the compartment, and at least part of the boundary surface in the blowing direction of the perfusion blower is at least partially preferably opened. In addition, in the present invention, a plane parallel to the longitudinal direction of the perfusion blower, which is the rotation axis direction of the impeller of the perfusion blower, is a width direction of the blowing compartment, and the direction parallel to the blowing direction of the perfusion blower is the longitudinal direction of the blowing compartment. Direction.

1 is a plan view showing an embodiment of a blowing section in the present invention, and FIG. 2 is a longitudinal sectional view of the blowing section shown in FIG. The blowing section 1 here is shown in FIGS. 1 and 2

As shown in the drawing, airflow is generated within a specific range within a compartment (space) of the bottom surface 8 and the ceiling surface 9 and the four boundary surfaces 2, 3, 4 and 5 of the side. The perfusion blower 6 is provided and comprised. In the blowing section 1 of this embodiment, the boundary surface 3 is opened except for the upper girder portion to form an open boundary surface in the blowing direction of the perfusion blower, and the boundary surface 2 and the boundary surface 4 are entirely It is a closed wall. The remaining interface 5 may not be opened as described later.

The size of the blowing section 1 is about the width direction length W0 of the blowing section 1.

Mainly set appropriately based on the part partitioned by wall or strut. In addition, when there is no partition, such as a wall or a support | pillar, you may partition at arbitrary positions.

The longitudinal length L0 of the blowing section 1 is set according to the arrival length ALl of the airflow 7 generated from the perfusion blower 6 to be installed. The arrival length ALl of the airflow 7 is determined by the blowing capacity of the perfusion blower 6, the discharge angle θ1 of the airflow 7, the floor height H0 of the building, and the like. On the contrary, the longitudinal length L0 of the blower outlet 1 may be determined first, and the blowing capacity of the perfusion blower 6 may be set in accordance with the L0.

In addition, in the present invention, in order to blow air efficiently, the air flow generated in the blowing section 1 within the building is blown in the blowing direction except for a part of contact with an external device such as an external air intake device, forced exhaust device, or air conditioner. The blowing section is set to reach within the blowing section 10 adjacent to the defined boundary surface 3. 3 and 4 are simplified views illustrating the reach of the air flow of the blowing section 1 according to the above embodiment, respectively.

3 shows a case where the blowing direction of the perfusion blower 6b of the songpon section 10 is orthogonal to the blowing direction of the perfusion blower 6 of the blowing section 1, in this case, the blowing section l. The range of the airflow 7 in the airflow section 10 is such that the airflow 7 of the permeation blower 6 of the blowing section 1 is adjacent to the open boundary 3 in the blowing direction of the blowing section 1. The airflow 7 of the blowing section 1 reaches into the blowing section 10 so as to be easily attracted to the blowing section 10. In addition, it is preferable to allow the air flow 7 to be attracted more easily if the range AL2 of the air flow of 5% or more of the reach length ALl of the airflow blower 6 from the permeation blower 6 interferes with the air blowing compartment 10. .

4 shows a case where the blowing direction of the perfusion blower 6 of the blowing section 1 and the blowing direction of the perfusion blower 6b of the blowing section 10 are the same, and in this case, the airflow of the blowing section 1 The range of 7) is that the air flow 7 of the blowing section 1 is blown so that the air flow 7 of the permeation blower 6 of the blowing section 1 is attracted to the air flow of the blowing section 10 so that it can be conveyed sequentially. Reach the perfusion blower 6b of the compartment 10. In addition, when the airflow range AL2 of 5% or more of the airflow 7 reaching length AL1 from the perfusion blower 6 interferes with the airflow of the perfusion blower 6b, the airflow 7 tends to be conveyed more sequentially. It is preferable because of that.

Next, the perfusion blower used for the ductless blowing system of this invention is demonstrated. Although the type of perfusion blower used in the ductless blower system of the present invention is not particularly limited, the blower blower can be blown over a wide range of the width direction of the blower compartment in the present invention. Do.

5 shows an embodiment of a perfusion blower for use in the ductless blower system of the present invention, wherein the illustrated perfusion blower 101 includes a drive device 103, an impeller 104, and a control device constituting the blower. The main parts such as 105 are integrally incorporated in the casing 102 of aluminum extrusion. The casing 102 is provided with an air suction port 106, an airflow outlet 107, and a mounting flaw. The perfusion blower 101 is mounted on a ceiling surface 9, a wall surface, or the like by an attachment bracket fitted to the attachment flaw. I can attach it. In addition, the perfusion blower 101 may arbitrarily change the discharge direction of the airflow by attaching the broguides 108 and 109 to the attachment defects as necessary. Further, the flow-through blower 101 may be connected in plural in the longitudinal direction thereof, and the connection is performed by coupling the casings 102 to each other in a state where the cover of the longitudinal end of the casing 102 is removed. Therefore, the impeller 104 can also be combined easily.

Such a perfusion blower 101 is lightweight as described above, and since the air flow outlet 107 is long in the width direction of the blowing section, it is possible to blow substantially uniformly in a wide range of the width direction, and the driving device 103 has a low power. Even in this case, since a large amount of air can be blown, the running cost can be reduced, and further, main parts are integrated in the casing 102, and the cross-sectional area of the direction perpendicular to the width direction is reduced by the use of the impeller 104. It is suitable for the ductless blowing system of the present invention because it has a high degree of freedom of attachment, can be freely installed on a ceiling surface, a wall surface and the like, and can greatly facilitate the attachment work.

Next, the airflow generated in the blowing section in the present invention will be described. In the ductless blowing system of the present invention, the airflow is generated in a wide range within the blowing section at a time from the airflow outlet of the perfusion blower in terms of suppressing uneven blowing and improving the blowing efficiency. In the air blowing section, there are no objects that obstruct the airflow. In the air blowing section, the air blowing section blows air in a wide range so that the air does not get stuck.In the air blowing section where there are objects that impede the airflow, such as parking in the parking lot. The airflow is blown to the wall or the gap with the object so that the airflow is not blocked by the airflow.

For this reason, in the present invention, the width W1 (see FIG. 1) of the airflow outlet of one perfusion blower provided in the blowing section, or the sum W1 of the widths of the airflow outlets of the plurality of perfusion blowers blowing in the same direction A perfusion blower is installed to be 15% or more of the width (W0) of the blowing section and 75% or less in length. If the length of W1 is less than 15%, uneven blowing in the width direction of the blowing section is easy to occur, and if it exceeds 75%, it is difficult to install in the blowing section because the total length of the perfusion blower is increased. Because. In addition, if the length of W1 is within the range of 20% or more and 50% or less of W0, it is possible to secure a sufficient airflow amount for agitating and replacing the air in the air blowing compartment, and at the same time reduce the installation cost. It may be easy.

In the present invention, the length of W1 is first set on the basis of the width (WO) of the blowing section based on the assumption that there are no obstacles to airflow in the blowing section, and is appropriately changed when there may be an obstacle. In addition, the number of perfusion blowers to be set in the blowing section may be any number, and may be appropriately selected according to the width of the blowing section (WO) or the presence or absence of obstacles, and may be blown in a wide range in the width direction to prevent the occurrence of uneven blowing. It is possible to suppress and stir the air in the blowing section, replace the air, and return the air efficiently.

Next, the attachment position of the perfusion blower provided in a blowing compartment by this invention is demonstrated. When there is no object that impedes the flow of airflow in the blowing compartment, the installation position of the blowing section in the width direction is generated by matching the center of the width direction of the airflow outlet of the perfusion blower with the center of the blowing section in the width direction. It is preferable because the air flow can flow almost uniformly. In case of obstacles, the airflow can be installed in a location where it is easy to shed, or can be distributed in the same direction.

Next, the attachment position of the width direction perfusion blower of a blowing compartment in the case where there exists an object which becomes an obstacle of an airflow in the above blowing section is demonstrated concretely. For example, a parking lot is taken as an example of a building with objects that impede airflow. FIG. 6 is a ping sectional view illustrating a state in which vehicles C1 and C2 are parked in the blowing section 1 shown in FIG. 1, and FIG. 7 is a longitudinal sectional view of the blowing section 1 shown in FIG. . As shown in FIG. 6, when the space | interval part of two vehicles C1 and C2 becomes substantially center of the width direction of the blowing compartment 1, the airflow 7 can be blown in the space | interval part, so perfusion It is preferable to provide the perfusion blower 6 by making the center of the width direction of the airflow discharge part of the blower 6 coincide with the center of the width direction of the blower compartment 1.

8 shows the blowing section 11 based on a vehicle parked in the width direction. In this case, since the spacing of the vehicle C3, C4, C5 of the generation is two places, two perfusion blowers may be spaced apart in the same direction, but even if one perfusion blower is installed from the economy, it is installed in the blow section 11 Since the airflow outlet width of the perfusion blower is greater than l5% and less than 75% of the width W0 of the compartment as described above, the airflow can be blown between the two spaces. In the case of providing one such perfusion blower, it is preferable to install the perfusion blower 16 by matching the widthwise center of the airflow discharge portion of the perfusion blower 16 with the widthwise center of the blowing compartment 11.

9 shows the blowing section 21 with four vehicles parked in the longitudinal direction. In this case, if airflow is blown between the boundary surface 23 formed of the wall surface and the vehicle C6, C7, C8, C9, the airflow can be efficiently blown in the blowing section 21, so that the width of the perfusion blower 26 is reduced. A perfusion blower 26 is provided by closely attaching the attachment position in the direction toward the boundary surface 23 side.

In this way, as an attachment position in the width direction of the permeation blower, when there is an object which becomes a window airflow in the blowing section, a position that can efficiently blow in the blowing section can be appropriately selected without being blocked by the blocking object. .

In the present invention, on the attachment position in the longitudinal direction of the blowing section of the perfusion blower provided in the blowing section, the airflow and agitation efficiency and the range of airflow reaching the blowing section adjacent to the open boundary are appropriately considered. Choose. For example, in the blowing section 1 shown in FIG. 1, when the boundary surface 5 opposite to the blowing direction is formed on the wall blocked entirely, the perfusion blower 6 is provided on the wall surface forming the boundary surface 5. It is preferable that the air flow is blown in a long range in the longitudinal direction of the blowing section. In the case where the boundary surface 5 is partially or entirely open, the perfusion blower 6 is provided at a position to easily intake external air, air-conditioned air, or air blown from an adjacent blowing section. It is desirable to be able to convey air efficiently.

In the present invention, the attachment height Hl (see FIG. 1) of the perfusion blower installed in the blowing section is generally located at the upper portion of the inside of the building in terms of air conveyance and stirring effect. It is also possible to change the height appropriately, such as lowering the attachment height in accordance with the shape of the compartment. For example, if a permeation blower is installed at the height corresponding to the middle position of the up-and-down two-stage vehicle, such as a two-stage parking lot, when the efficiency of conveying and agitating the airflow is improved, Install a perfusion blower.

The wind speed in the blowing section in the present invention is appropriately set in accordance with the purpose of blowing and the setting position of the blowing section. For example, in the case of mainly air conditioning, the average wind speed in the blowing section is set to about 0.2 m to 10 m so as to maintain comfort. In addition, in the case of mainly ventilating, the average wind speed in the blowing section is about 0.2m to 1.5m to increase the frequency of replacement of the air inside the blowing section. In addition, since the wind speed is such that there are few objects that obstruct the airflow, such as the air flow passage set in the passage and the lane, in the air flow passage that can continuously flow the air flow, the air flow velocity is increased to the surrounding air flow passage. It can be set appropriately according to the shape of the inside of the building, for example, to easily inhale airflow.

The discharge angle (theta) 1 (refer FIG. 1) of a perfusion blower in this invention is set so that agitation and conveyance of air can be simultaneously and efficiently performed in a blower compartment. For this reason, in the present invention, the center angle of the airflow blown with the discharge angle θ1 of the perfusion blower at an oblique downward direction is preferably within an angle of 5 ° to 60 ° downward in the angle range of 0 ° to 90 ° downward with respect to the horizontal direction. Set to be within the range. It is because it is difficult to carry out stirring and conveyance of air simultaneously and efficiently outside this angle range of 5 degrees-60 degrees.

In addition, the discharge angle (theta) 1 of a perfusion blower is suitably selected according to the attachment height H1 of a perfusion blower. For example, when H1 is 3.0 m, it is preferable to set discharge angle (theta) 1 to the angle of 10 degrees-30 degrees downward from a viewpoint of a gas conveyance and stirring effect, and the number of perfusion blowers installed.

The adjustment of the discharge angle θ1 of the perfusion blower can be performed by adjusting the set angle of the perfusion blower itself or the attachment angle of the broguide, or a combination thereof. In addition, the angle of the perfusion blower itself or the broguide can be changed by a drive device having a motor or the like, so that the discharge angle can be changed at any time according to the need when switching between heating and cooling.

Next, the flow of air in the building in which the ductless ventilation system of this invention was installed is demonstrated. FIG. 10 is a plan view showing a state in which a ductless blowing system of the present invention is installed in a parking lot by combining a plurality of blower compartments of the present invention for air ventilation in the parking lot. The ventilation system installed in the parking lot 41 shown in FIG. 10 is provided with the outside air intake apparatus 43 and the forced exhaust apparatus 44, and the air blowing sections 45, 46, 47 set in the lanes, and the air blowing sections 48, 49) and air blowing compartments 50, the air blowing compartments 51, 52, 53, 54, 55, 56, 57, 58, 59, and the air blowing compartments 60, 61, 62, 63, 64, 65, 66, 67, 68, and a blowing section 69, wherein blowing sections 45, 46, 47, blowing sections 48, 49, and blowing sections 50 are set in the lanes, respectively. Air blowing compartments (51,52,53,54,55,56,57,58,59), air blowing compartments (60,61,62,63,64,65,66,67,68) The ventilation openings 69 constitute the ductless blowing system of the present invention. In addition, the blowing section 68 is set to include not only a vehicle but also a lane in the area so that the airflow therefrom reaches the blowing section 50.

The ventilation section 45, 46, 47, the blowing section 48, 49, and the blowing section 50 set in the lane in this ventilation system, and the blowing section 68 set in the vehicle compartment and also including the lane Air flow is set in the air blowing section (51, 52, 53, 54, 55, 56, 57, 58, 59), blowing section (60, 61, 62, 63, 64, 65, 66, 67) and blowing section ( It is desirable to speed up the flow rate so as to easily attract the airflow discharged from the air.

Referring to the flow of airflow in the parking lot 41 shown in FIG. 10, the outside air 70, 7l introduced into the parking lot 41 from the vehicle entrance 42 and the outside air intake apparatus 43 is driven by a car. It blows to the forced exhaust apparatus 44 side by the perfusion blower of the blowing compartments 45 and 48 set at.

In addition, in the air blowing compartment 45, the outside air 70 introduced into the right half portion in FIG. 10 is conveyed by the blowing compartments 45, 46, 47 set in the lane, and each blowing compartment set in the vehicle compartment ( 51, 52, 53, 54, 55, 56, 57, 58, and 59 are agitated with a lot of exhaust gas, and then discharged to the lane side again. The discharged airflow is attracted to the airflow of the blowing section 45, 46, 47, blown to the forced exhaust device 44, and discharged to the outside by the forced exhaust device 44.

Similarly, the outside air 71 introduced into the range of the left half portion in FIG. 10 by the blowing section 48 is conveyed by the blowing sections 48 and 49 set in the lane while being set in each blowing section ( 60, 61, 62, 63, 64, 65, 66, 67, and stirred and discharged back to the lane. The airflow discharged to the side of the lane is attracted to the airflow of the blowing section 48 and 49, and is set in the vehicle compartment and blown to the blowing section 68 including the lane.

The airflow blown to the blowing section 68 side is attracted to the blowing section 68 and the blowing section 50 set in the lane, and is blown to the blowing section 47 set in the lane and forced by the blowing section 47. It blows to the exhaust apparatus 44 side, and is discharged | emitted to the exterior by the forced exhaust apparatus 44. FIG. The blowing section 69 introduces air from the blowing section 68, 50 side, and blows it to the forced exhaust device 44 side.

In the case of using the ventilation system for the ventilation of the parking lot, it is required to efficiently ventilate and efficiently discharge the outside air introduced into the parking lot from the outside and the air containing a large amount of exhaust gas in the parking lot and to discharge it to the outside efficiently. In the ductless blowing system of the present invention, as described above, the airflow generated in each blowing section is blown almost uniformly in a wide range in the width direction at one time, and is exchanged with other blowing sections. Therefore, according to the ductless blowing system of the present invention, the air in the parking lot 41 can be efficiently stirred, blown and ventilated.

In addition, the ductless blowing system of this invention is not limited to embodiment mentioned above, It can install and install a blowing section suitably according to the form of a building, the position of a forced exhaust apparatus, etc. In addition, the ventilation system of the parking lot can be reconfigured by adding the ductless air blowing system of the present invention to the ventilation facility of the existing parking lot.

FIG. 11 is another embodiment in which the ductless air blowing system of the present invention is installed in a building, and in order to improve air conditioning, a plurality of air blowing compartments of the present invention are combined and installed in a building 81 such as a hall or a factory. The state is shown in plan view. The air conditioning system shown in FIG. 10 is constituted by air conditioners 82, 83, 84 and 85, and air blowing compartments 86, 87, 88, 89, 90, 91, 92 and 93. The blowing sections 86,87,88,89,90,91,92,93 constitute the ductless blowing system of the present invention.

In the embodiment shown in FIG. 11, three through-flow blowers of the same direction are provided to each of the blowing sections 86,87,88,89,90,91 for the purpose of setting each blowing section wide in the building 81. It is provided apart from each other, and the direction of the blowing section for the purpose of circulating the air flow in the building 81, and the direction of the perfusion blower is transverse to the blowing section (86,87,88,89,90,91). Two blowing sections 92 and 93 facing in the direction are set. In addition, the air flow generated in the blowing sections 92 and 93 is preferably slightly increased in flow velocity so as to easily attract the air flows in the blowing sections 86, 87 and 88 and the blowing sections 89, 90 and 91. However, it is preferable that the speed of the airflow in this case is made high so as not to impair comfort.

Referring to the flow of airflow in the building 81 shown in FIG. 11, the air conditioning air generated from the air conditioners 82 and 83 is blown by the perfusion blower of the blowing section 86, and the blowing section 86 And 87,88 are sequentially conveyed to the blowing section 92. The blowing section 92 is blown to the blowing section 89 side. Similarly, the air conditioning air generated by the air conditioner (spoiler) 85 is blown by the perfusion blower of the blowing section 89, and is blown through the blowing sections 89, 90, and 91 sequentially to the blowing section 93. . The blowing section 93 is blown to the blowing section 86 side. For this reason, the air conditioning air generated by the air conditioners 82 and 83 and the air conditioners (read and 85) is circulated in the building 81 and blown to a wide range.

In the case of using a blowing system for the purpose of controlling the air conditioning in the building, it is possible to convey the air conditioning air generated from the air conditioner to the whole building or to the required part while stirring efficiently with the air in the building. Although required, in the ductless blowing system of the present invention, as described above, the airflow generated in each blowing section is blown almost uniformly in a wide range in the width direction at once, and is exchanged with other blowing sections. Therefore, according to the ductless blowing system of this invention, it can convey efficiently, stirring the air in the building 81. FIG.

In addition, the ductless ventilation system of this invention is not limited to the above-mentioned embodiment, For example, according to the installation form of a gun, an air conditioner, etc., the air conditioner is provided adjacent to only one wall surface, for example. In the case of setting the blowing section to blow in one direction, and if the air conditioner is installed adjacent to each of the two opposing walls, the blowing section is set so that the blowing section can be efficiently blown. You can set up and install it. In addition, the air conditioning system of the building can be reconfigured by adding the ductless blowing system of the present invention to an existing air conditioning system.

Next, the control method in the case of adding a blowing control apparatus to the ductless blowing system of this invention is demonstrated. The blowing control apparatus to be added can be appropriately selected according to the blowing purpose, such as a timer type. FIG. 12 shows an embodiment of the blowing control device added to the ductless blowing system of the present invention. The blow control device 201 shown in FIG. 12 can be used in the case where the inside of a building is tightly controlled and blown. Here, three cases of blow sections 211, 212 and 213 are shown. The blowing control apparatus 210 is comprised by the control panel 202 and the sensors 221,222,223.

The sensors 221, 222, and 223 are provided at the appropriate blowing sections as the blowing sections or detection positions, and are installed in the blowing sections 211, 212, and 213, respectively, in the illustrated example. The control panel 202 includes a setter 203 for setting the environment in the building, such as a pollutant gas concentration for ventilation purposes, and a temperature for air conditioning, and an extractor 204 for receiving signals from the sensors 221, 222, and 223; It is comprised by the controller 205 which calculates a control value from the output value of the setter 203 and the detector 204, and controls the air flow amount (the impeller rotation speed of a perfusion blower). When the perfusion blower itself or its broguide is angularly variable by the drive device, the controller 205 also controls the angle of the perfusion blower itself or the broguide.

The detector 204 receives a signal indicating the pollution concentration or temperature of the blowing section from the sensors 221, 222, and 223 and outputs an environmental value. The controller 205 compares the environmental value and the set value, and transmits a control signal to the perfusion blower of each blowing section based on the difference to individually control each blowing section 211, 212, 213.

When such a blow control device is used in the ductless blowing system of the present invention, detailed blowing can be controlled for each blowing section, and thus, the blowing state in the building can be controlled to a specific part, such as intensive blowing at a specific blowing section. Blowing can be performed with better efficiency.

From the measurement results, it can be seen that the ductless blowing system of the present invention blows airflow in a wide range within the parking lot by the blowing section provided in the lanes and the car compartment, thereby bringing excellent conveying and stirring effect of the air.

As described above, the present invention provides a flow-through blower that blows airflow in a wider range in comparison with an axial blower in a building or in a plurality of the flow-through blowers that blow in the same direction. Since a plurality of airflow blowers are provided so as to reach the air flows from the plurality of the above-mentioned blowers blowed in the same direction or different from each other, or in the same direction, it is possible to blow efficiently even in a building having a large floor area. A plurality of blowing sections are set, and through-flow blowers are provided in these blowing sections, respectively, and the airflows generated in the blowing sections are blown over a wide range in the width direction as described above, and another blowing section adjacent to the open boundary in the blowing direction is provided. Since it reaches inside, airflow can be generated and blown more efficiently. .

In addition, when the length in the width direction of the air flow outlet of the perfusion blower installed in the blowing section and the length in the width direction of the blowing section is 15% or more and 75% or less, the perfusion blower blows the air flow in the entire range. Since a wide range in the width direction of the blowing section can be blown roughly and uniformly, the blowing is not uniform and the blowing and the agitation of the air can be performed more efficiently.

In addition, if the air flow range reaching the other blowing section is 15% or more of the air flow reaching length in the permeation blower, the air can be conveyed more efficiently.

As described above, since a building having a large floor area can be blown without using a long blower duct, the construction cost of the blower system can be reduced, and the width of the blower required is larger than the distance between the left and right walls. Since the number of blowers to be installed can be shortened and the number of blowers to be installed can be reduced, equipment cost can be reduced.

By using a perfusion blower, a sufficient blowing amount can be generated by a driving device that saves power, thereby reducing the running cost.

If the flow-through blower provided in the blowing section is a flow-through blower in which main parts are integrated as shown in Fig. 9, the total number of parts can be reduced, so that the equipment cost can be reduced.

When the widthwise length of the airflow outlet is 15% or more of the widthwise length of the blower section and the length of 75% or less, the overall length (widthwise length) of the blower can be shortened, and the components of the blower are once Since it can be attached to, it can be attached easily to a ceiling etc. In addition, since the blower can be light and thin, it can be easily attached in this respect.

Since only a plurality of perfusion blowers are installed in the building, it is easy to install the blower system, so that the blower system can be installed fairly easily according to the shape of the building and the purpose of the blower.

In addition, since the required width of the blower can be made shorter than the distance between the left and right walls, the overall length of the impeller of the blower can be shortened, so that noise generated can be reduced.

In addition, when the blowing control is performed by the blowing control device, the blowing can be controlled for each blowing section, and the blowing in the gun can be finely controlled, such as intensively blowing in a specific blowing section. have.

Next, the effect by blowing purpose is demonstrated. First, the case where the ductless air blowing system of the present invention is used for the ventilation of a parking lot will be described. When the air blowing compartment is set in the vehicle compartment, the vehicle can be uniformly blown in a wide range in the width direction of the vehicle compartment. It is possible to ventilate the cabin regardless. In addition, since the air can be uniformly blown in a wide range in the width direction, air can be prevented from becoming cloudy, and the air in the cabin including exhaust gas can be efficiently ventilated and discharged out of the cabin.

In addition, when the blowing section is set in the lane, the blowing section can be efficiently blown in a wide range in the width direction, so that the outside air taken into the parking lot can be efficiently transported along the lane and discharged from the blowing section of the cabin. The used air can also be efficiently conveyed.

In addition, since the air is blown in a wide range in the width direction, it is possible to easily supply the outside air to the blowing compartment of the vehicle compartment and at the same time to attract the air discharged from the blowing compartment of the vehicle compartment. For this reason, since the balance of the airflow in the blowing compartment of a vehicle compartment and the airflow in the blowing compartment of a lane can be maintained, the whole inside of a parking lot can be ventilated efficiently.

The installed perfusion blower can reduce the cross-sectional area in the direction perpendicular to the width direction, so that the blower can be stored between the ceiling surface and the lower surface of the ceiling girders, thereby lowering the floor height of the parking lot building. Can reduce construction cost. In addition, since the blower can be stored between the ceiling surface and the lower surface of the ceiling girders, it is possible to improve the passability of the vehicle having a high vehicle height.

Since there is no need to surround the ventilation duct for the ceiling or the like, the installation of the ventilation system is quite easy even in a newly or already installed parking lot.

When used for the purpose of efficient air conditioning in a large building such as a hall or a factory, the air conditioning air generated by the air conditioner is stirred with the air in the building in a wide range in the width direction, and at the same time, the airflow between the blowing sections is reached. The air can be conveyed and conveyed in the longitudinal length range while mixing the airflow, so that air conditioning can be efficiently performed even in a building having a large floor area.

Since the air can be blown in a wide range in the width direction of the air blowing section, the airflow becomes a spot type like the axial blower, so that the air is not intensively blown, and comfortable air conditioning can be performed.

In addition, since the air conditioning can be performed efficiently by blowing in a wide range, it is possible to shorten the operating time of the air conditioner and to reduce the running cost.

In addition, since there is no need to surround the blower pipe of the blower duct for the ceiling or the like, the installation of the blower system is quite easy even in a newly or already installed building. In addition, since the setting of the blowing section is easy, it is possible to easily set the blowing section so as to efficiently generate the blowing air flow in accordance with the shape of the building or the installation position of the air conditioner.
