Description

[Technical field]

[0001] The present invention relates to an air conditioning system, and more particularly to an air conditioning system having an air curtain forming device. [Background technology]

[0002] Conventionally, in facilities with large spaces such as factories, air conditioning systems that divide target areas and perform air conditioning are used. For example, the air conditioning system in Patent Document 1 discloses that four air curtain forming devices are arranged on the ceiling and the air curtain forming devices blow air toward the floor surface to divide the area to be air-conditioned.

[0003] However, according to the air conditioning system of Patent Document 1, since the air curtain forming device is placed on the ceiling, other equipment cannot be installed near the ceiling of the area to be air-conditioned, and there is a risk that the area cannot be used effectively. Furthermore, it is necessary to install an air conditioner for each partitioned area. Also, the air conditioning system of Patent Document 1 only blows conditioned air from the ceiling to air-condition the partitioned area, and there is a risk that the partitioned area cannot be air-conditioned efficiently.

[0018] Hereinafter, an air conditioning system according to one embodiment of the present invention will be described with reference to the drawings.

[0019] First Embodiment Fig. 1 is a plan view of an air conditioning system according to a first embodiment of the present invention. As shown in Fig. 1, the air conditioning system 1 includes an air curtain forming device 11 that blows out a lateral air flow, an air conditioner 13, and a circulation device 12 that circulates the conditioned air between the air curtain forming devices.

[0020] (Air curtain forming device) Fig. 2 is a schematic diagram showing an outline of the air curtain forming device 11. As shown in Fig. 2, the air curtain forming device 11 includes a rectangular parallelepiped housing 111, an inlet 112 formed on a first surface of the housing 111, and an outlet 113 formed on a second surface adjacent to the first surface of the housing 111. For example, the size of the housing 111 of the air curtain forming device 11 is appropriately designed according to the area to be partitioned. The shape of the housing is not limited to a rectangular parallelepiped, and examples thereof include a cube, a cylinder, and a polygonal prism.

[0021] For example, the suction port 112 of the air curtain forming device 11 is preferably a rectangle having a width of 500 mm or more and 1,000 mm or less and a height of 500 mm or more and 1,500 mm or less. The suction port 112 of the air curtain forming device 11 is preferably formed 100 mm or more and 1,000 mm or less from the bottom surface of the housing 111, and from the viewpoint of efficiently sucking air from the partitioned area, it is more preferably 100 mm or more and 300 mm or less from the bottom surface of the housing. The shape of the suction port 112 of the air curtain forming device 11 is not limited to a rectangle, and examples thereof include a square, a circle, and a polygon.

[0022] The shape and number of the air outlets 113 of the air curtain forming device 11 are appropriately designed according to the volume of the air flow. In addition, the air curtain forming device 11 can adjust the direction of the air outlets 113 and change the direction of the air flow by further including an air direction adjustment unit of the air curtain forming device 11 attached between the housing 111 and the air outlets 113. For example, the range in which the air outlets 113 of the air curtain forming device 11 are formed is preferably 300 mm or more and 500 mm or less in width and 300 mm or more and 500 mm or less in height. In addition, the range in which the air outlets 113 of the air curtain forming device 11 are formed is preferably 100 mm or more and 300 mm or less from the bottom surface of the housing 111. In FIG. 2, the air outlets 113 of the air curtain forming device 11 are circular in front view, and three of them are arranged vertically. For example, the size of the circle is preferably 300 mm or more and 500 mm or less in diameter. However, the shape of the air outlets 113 is not limited.

[0023] The air curtain forming device 11 is configured to suck in air from the suction port 112 and blow out an air flow laterally from the blowing port 113. The wind speed of the air flow is designed appropriately depending on the distance at which the air curtain is to be formed. By appropriately arranging the air curtain forming devices 11, the area and height of the area to be air-conditioned can be defined from the combination of the air flows. In FIG. 1, four air curtain forming devices 11 are arranged at each vertex so that the area to be air-conditioned is approximately square in a plan view, but an appropriate number of air curtain forming devices 11 can be arranged according to the area to be air-conditioned.

[0024] (Air conditioner) 1, the air conditioner 13 is installed on the ceiling or under the floor, and configured to blow cool air to the area to be conditioned. As the air conditioner 13, a known one is used.

[0025] (circulation device) Fig. 3 is a schematic diagram showing an outline of circulation device 12. As shown in Fig. 3, circulation device 12 includes a rectangular housing 121, an inlet 122 formed on a first surface of housing 121, and an outlet 123 formed on the first surface of housing 121 above the maximum height of inlet 122. The shape of housing 121 is not limited to a rectangular parallelepiped, and examples thereof include a cube, a cylinder, and a polygonal prism.

[0026] For example, the suction port 122 of the circulation device 12 is formed 200 mm or more and 1,000 mm or less from the bottom surface of the housing, and from the viewpoint of efficiently drawing in cool air, it is preferably formed 200 mm or more and 500 mm or less from the bottom surface of the housing. The shape of the suction port 122 of the circulation device 12 is not limited to a rectangle, and may be a square, a circle, a polygon, or the like.

[0027] For example, the range in which the air outlets 123 of the circulation device 12 are formed is set to 2,000 mm or more and 3,500 mm or less from the bottom surface of the housing 121. In Fig. 3, three air outlets 123 of the circulation device 12 are arranged vertically when viewed from the front. The shape and number of the air outlets 123 of the circulation device 12 are appropriately designed depending on the volume of air to be blown out, and are not limited to these. In addition, the circulation device 12 further includes a wind direction adjustment unit of the circulation device 12 attached between the housing 121 and the air outlets 123, and the direction of the air to be blown out can be adjusted to change the wind direction of the air to be blown out.

[0028] The circulation device 12 is configured to suck in air in the area to be conditioned from the intake port 122 and blow the air out to the area to be conditioned from the exhaust port 123. This allows the air in the area to be conditioned to circulate, thereby enabling efficient air conditioning. In Fig. 1, one unit is placed at the apex of the area to be conditioned, but it may be placed at each apex.

[0029] Although the air conditioning system according to the first embodiment of the present invention has been described above, the specific aspects of the present invention are not limited to the above embodiment. For example, the circulation device 12 has one suction port 122 formed in the housing 121, but the first suction port 122 and the second suction port 122' can be formed on the first surface of the housing 121 and the second surface, which is the back surface, respectively, so as to suck in air from an inner area (area to be air-conditioned) of the target area and an outer area (area not to be air-conditioned) of the target area. The circulation device 12 can further include a processor that measures and compares the temperatures of the air from the first and second suction ports 122, 122', so that the air from the first and second suction ports 122, 122', which have a lower temperature, can be sucked into the area to be air-conditioned. Furthermore, the air sucked in by the circulation device 12 may be provided with an air-conditioning function. By providing the circulation device 12 with an air-conditioning function, the air-conditioning capacity can be enhanced.

[0030] In the first embodiment, as shown in FIG. 1, the air conditioner 13 is configured to blow air conditioned by the air conditioner 13, but by configuring the circulation device 12 to further include a heat exchanger disposed inside the housing 121, the circulation device 12 can have an air conditioning function such that the conditioned air is blown out from the air outlet 123. This makes the air conditioner 13 unnecessary in the air conditioning system 1, and allows the area to be conditioned to be used more effectively. Also, by configuring the air curtain forming device 11 to further include a heat exchanger disposed inside the housing 111, the air curtain forming device 11 can have an air conditioning function such that the air curtain forming device 11 blows out conditioned air from the air outlet 113. This allows the partitioned area to be air conditioned efficiently.

[0031] <Second embodiment> Next, an air conditioning system according to a second embodiment of the present invention will be described. Fig. 4 is a plan view of the air conditioning system 1 according to the second embodiment of the present invention. As shown in Fig. 4, the air conditioning system 1 has an air curtain forming device 11 consisting of first and second air curtain forming devices 11a and 11b, and a circulation device 12 consisting of first and second circulation devices 12a and 12b.

[0032] Fig. 5 is a schematic diagram showing an outline of the first and second air curtain forming devices 11a and 11b. As shown in Fig. 5, the air curtain forming devices 11a and 11b include a housing 111 that is a rectangular prism that is an isosceles trapezoid in a plan view, an intake port 112 formed on a surface of the housing 111 that corresponds to the upper base of the trapezoid, and first and second outlet ports 113a and 113b formed on the surfaces of the housing 111 that correspond to the legs of the trapezoid. The shape of the housing 111 is not limited to an isosceles trapezoid rectangular prism, and may be a cube, a cylinder, a polygonal prism, or the like.

[0033] The suction port 112 and the blow-out ports 113a, 113b of the air curtain forming devices 11a, 11b are configured in the same manner as the air curtain forming device 11 of the first embodiment. The air curtain forming devices 11a, 11b are formed so that the suction port 112 draws in air from the area to be conditioned within the height range from which the blow-out ports 113a, 113b blow out the airflow, so that the suction port 112 does not draw in air from the area not to be conditioned, thereby enabling efficient air conditioning. The air curtain forming devices 11a, 11b of the second embodiment can blow out lateral airflows in two directions.

[0034] Fig. 6 is a plan view of the first and second air curtain forming devices 11a and 11b. As shown in Fig. 6, the air inlet 112 is disposed between the first and second air outlets 113a and 113b. The first and second air outlets 113a and 113b are formed at an angle α of approximately 90° (85° or more and 95° or less). The angle α of the first and second air outlets 113a and 113b is not limited to approximately 90°, but is appropriately designed according to the shape of the area to be air-conditioned, and can be, for example, an angle of 45° or more and 180° or less.

[0035] The first and second circulation devices 12a, 12b each have the same configuration as the circulation device 12 according to the first embodiment.

[0036] As shown in Fig. 4, the first and second air curtain forming devices 11a, 11b are arranged to face each other with a first diagonal line D1, and the first and second circulation devices 12a, 12b are arranged to face each other with a second diagonal line D2. The first and second air curtain forming devices 11a, 11b and the first and second circulation devices 12a, 12b are arranged so that the first diagonal line D1 and the second diagonal line D2 intersect. The first circulation device 12a is arranged to suck in the air blown out from the first blowing port 113a of the first air curtain forming device 11a and the air blown out from the second blowing port 113b of the second air curtain forming device 11b. The second circulation device 12b is arranged to suck in the air blown out from the second blowing port 113b of the first air curtain forming device 11a and the air blown out from the first blowing port 113a of the second air curtain forming device 11b. The first and second circulation devices 12a, 12b may be configured in pairs so that each circulation device sucks in the air flow blown out from one air curtain forming device.

[0037] According to the air conditioning system of the second embodiment, the first and second air curtain forming devices 11a and 11b blow out airflows in the horizontal direction, thereby dividing the area to be conditioned into a substantially square shape in a plan view. The first and second circulation devices 12a and 12b take in the airflows blown out from the air curtain forming devices 11a and 11b, and blow out the conditioned air to the area to be conditioned. The first and second air curtain forming devices 11a and 11b then take in this conditioned air and blow it out again as an airflow, so that the air in the area to be conditioned is circulated, and efficient air conditioning can be achieved.
