Description

[Technical field]

[0001] The present disclosure relates to a ventilation system. [Background technology]

[0002] In winter, when the outside air temperature drops and the temperature of the window glass drops, the air that touches the surface of the window glass and is cooled becomes denser than the air inside the room. Therefore, the cooled air descends along the window glass and moves to the floor, then spreads throughout the room by crawling along the floor, lowering the air temperature in the lower layers of the room. To prevent this, cold protection boards are installed near the windows to prevent the cold air that comes down after touching the cold window glass from flowing to the center of the room (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3190818 Summary of the Invention [Problem to be solved by the invention]

[0004] Although installing a cold protection board prevents cold air from spreading throughout the room, the perimeter area near the window glass is cold and uncomfortable due to the cold air. As a result, the perimeter area is less utilized, and the utilization rate of the room decreases. In order to utilize the perimeter area, for example, a dedicated air conditioner for the perimeter area is installed. However, using a dedicated air conditioner increases energy consumption.

[0005] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a technology that improves comfort in perimeter areas while suppressing an increase in energy consumption. [Means for solving the problem]

[0006] In order to solve the above problems, an embodiment of the ventilation system disclosed herein comprises a ceiling fan and a window fan, the ceiling fan having a first intake port and a first exhaust port, the first intake port is positioned above an air conditioner suspended from the ceiling surface of a skeleton ceiling that does not have a ceiling panel, and sucks in air that has accumulated in the space above the air conditioner, the first exhaust port blows the air sucked in from the first intake port down toward the floor, the window fan has a second intake port and a second exhaust port, the second intake port sucks in the air blown down from the ceiling fan near the floor, and the second exhaust port blows the air sucked in from the second intake port up near the window.

[0007] Any combination of the above components, and conversion of the present disclosure into a method, device, system, recording medium, computer program, etc. are also valid aspects of the present disclosure. Effect of the Invention

[0008] According to the present disclosure, it is possible to improve the comfort of the perimeter area while suppressing an increase in energy consumption. [Brief description of the drawings]

[Diagram 2] FIG. 2 is a top view showing the configuration of a room in which the air conditioning system of FIG. 1 is installed. [Diagram 3] 3(a)-(b) are diagrams showing the configuration of the window fan of FIG. 1 and FIG. 2. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The examples described below each show a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, the arrangement and connection of the components, as well as the steps (processes) and the order of the steps shown in the following examples are merely examples and are not intended to limit the present disclosure. Therefore, among the components in the following examples, those components that are not described in the independent claims showing the highest concept of the present disclosure are described as optional components. In addition, in each figure, the same reference numerals are given to substantially the same configurations, and duplicated descriptions are omitted or simplified.

[0011] 1 is a cross-sectional view showing the configuration of a room 10 in which an air-conditioning system 1000 is installed. The room 10 is a space with a skeleton ceiling in which no ceiling panel is installed at ceiling panel position 30. A ceiling surface 20 is arranged above the room 10, a floor surface 22 is arranged below the room 10, and a window 24 is arranged on one side of the room 10. The space near the window 24, for example, within 3.5 m to 5 m from the window 24 toward the inside of the room 10, is a perimeter area 50. The perimeter area 50 is an area near a wall that is easily affected by outside air and sunlight, and is also called a perimeter zone.

[0012] The air conditioning system 1000 includes a first air conditioner 100a, a second air conditioner 100b, collectively referred to as air conditioners 100, a ceiling fan 200, a window-side fan 300, and a controller 500. Of these, the ceiling fan 200, the window-side fan 300, and the controller 500 are included in the air blowing system. The ceiling fan 200 includes a first housing 210, a first duct 220, a second duct 222, a first intake port 230, and a first outlet 232, and the window-side fan 300 includes a second housing 310, a second intake port 330, and a second outlet 332.

[0013] The air conditioner 100 is suspended from a ceiling surface 20, for example, at the height of a ceiling board position 30. The space between the ceiling board position 30 and the living room 10 is an upper space 40. The upper space 40 can be said to be the space above the air conditioner 100. The air conditioner 100 is, for example, a commercial air conditioner, and is capable of performing at least a heating operation and a cooling operation. When the air conditioner 100 performs a heating operation in winter, air (warm air) that is warmer than the overall average temperature of the living room 10 accumulates in the upper space 40.

[0014] A fan (not shown) is built into the first housing 210 of the ceiling blower 200. A first duct 220 extends from the first housing 210 to a first air inlet 230. The first air inlet 230 is an opening of the first duct 220, and is disposed in the upper space 40 above the air conditioner 100. For example, the first air inlet 230 is disposed above the air conditioner 100 and within 300 mm below the ceiling surface 20. A second duct 222 extends from the first housing 210 to a first air outlet 232. The first air outlet 232 is an opening of the second duct 222, and is disposed near the height of the ceiling board position 30.

[0015] As the fan of the first housing 210 rotates, the first air inlet 230 draws in air stagnating in the upper space 40. The air drawn in from the first air inlet 230 passes through the first duct 220, the first housing 210, and the second duct 222, and is transported to the first air outlet 232. The first air outlet 232 blows the air transported through the second duct 222, that is, the air drawn in from the first air inlet 230, down toward the floor surface 22. For example, the air is blown down toward the inside of the living room 10, further toward the perimeter area 50.

[0016] The window-side fan 300 is disposed below the window 24. A fan (not shown) is disposed inside the second housing 310 of the window-side fan 300. A second intake port 330 that opens toward the floor surface 22 is disposed below the second housing 310. A second outlet port 332 that opens along the window 24 is disposed above the second housing 310.

[0017] As the fan of the second housing 310 rotates, the second suction port 330 moves the air blown down from the ceiling blower 200 along the floor surface 22 toward the window 24, and then sucks in the moved air near the floor surface 22, for example, at a position about 50 cm high from the floor surface 22. The air sucked in from the second suction port 330 is transported to the second outlet 332 through the second housing 310. The second outlet 332 blows up the air sucked in from the second suction port 330 near the window 24, for example, at a position about 20 cm inside from the window 24. The air blown up from the second outlet 332 rises toward the ceiling surface 20 while following the surface of the window 24.

[0018] A desk 400 may be fixed to the second housing 310, and a chair 410 may be placed on the desk 400. The controller 500 is connected to the air conditioner 100, the ceiling fan 200, and the window fan 300 by wireless communication or wired communication, and controls the operations of the air conditioner 100, the ceiling fan 200, and the window fan 300.

[0019] FIG. 2 is a top view showing the configuration of a room 10 in which an air conditioning system 1000 is installed. A first housing 210 is installed inside the room 10, and a second duct 222 from the first housing 210 extends toward the window 24 and is connected to a first air outlet 232. The first air outlet 232 is an opening that extends in an elongated manner along the window 24, and is also called a breeze line. As shown in FIG. 2, a plurality of first housings 210 may be installed depending on the size of the room 10. In addition, the second duct 222 extending from the first housing 210 may be branched into a plurality of branches, and a plurality of first air outlets 232 may also be provided. Furthermore, a filter 240 may be provided in the second duct 222.

[0020] 3(a)-(b) show the configuration of the window fan 300. FIG. 3(a) shows the internal configuration of the window fan 300 when viewed from inside the living room 10, and FIG. 3(b) is a cross-sectional view of A-A' in FIG. 3(a). A second air inlet 330 that opens toward the floor surface 22 is disposed under the second housing 310, and a filter 320 is disposed above the second air inlet 330. The filter 320 provides an air cleaning function. A fan 322 is disposed above the filter 320. A slit-shaped second air outlet 332 is disposed above the fan 322 and on the window 24 side. In FIG. 3(a), two filters 320, two second air inlets 330, and two fans 322 are shown, but the present invention is not limited to this. With this configuration, when fan 322 rotates, air drawn in from second air inlet 330 passes through filter 320 and fan 322, and is blown up along window 24 from second air outlet 332.

[0021] The operation of the air conditioning system 1000 configured as above will be described. In winter, the controller 500 instructs the air conditioner 100 to perform heating operation, and instructs the ceiling fan 200 and the window fan 300 to operate. These instructions are given, for example, by wireless communication. When the air conditioner 100 performs heating operation, at least a portion of the (warmed) air blown out from the air conditioner 100 remains in the upper space 40.

[0022] The ceiling fan 200 draws in the warmed air stagnating in the upper space 40 through the first intake port 230 and blows it down towards the floor surface 22 through the first outlet port 232. The window-side fan 300 draws in the air blown down to the floor surface 22 through the second intake port 330 and blows it up along the window 24 through the second outlet port 332. The air blown up along the window 24 from the second outlet port 332 warms the area around the window 24, thereby increasing the temperature in the perimeter area 50. As a result, it is possible to place a desk 400 and a chair 410 in the perimeter area 50 and use the perimeter area 50.

[0023] On the other hand, in summer, the controller 500 instructs the air conditioner 100 to perform cooling operation, instructs the ceiling fan 200 to stop, and instructs the window fan 300 to operate. When the air conditioner 100 performs cooling operation, the (cooled) air blown out from the air conditioner 100 falls toward the floor surface 22 and accumulates near the floor surface 22.

[0024] Since the ceiling fan 200 is stopped, it does not blow air down from the first air outlet 232. The window-side fan 300 sucks in air that has accumulated near the floor surface 22 from the second inlet 330, and blows it up along the window 24 from the second air outlet 332. The air blown up along the window 24 from the second air outlet 332 cools the area around the window 24, lowering the temperature of the perimeter area 50. As a result, it is possible to place a desk 400 and a chair 410 in the perimeter area 50 and use the perimeter area 50.

[0025] The subject of the device, system, or method in the present disclosure includes a computer. The computer executes a program to realize the function of the subject of the device, system, or method in the present disclosure. The computer includes a processor that operates according to a program as a main hardware configuration. The type of the processor does not matter as long as it can realize the function by executing the program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). The multiple electronic circuits may be integrated into one chip or may be provided on multiple chips. The multiple chips may be integrated into one device or may be provided on multiple devices. The program is recorded on a non-transitory recording medium such as a computer-readable ROM, an optical disk, or a hard disk drive. The program may be stored in the recording medium in advance, or may be supplied to the recording medium via a wide area communication network including the Internet.

[0026] According to this embodiment, the ceiling fan 200 sucks in the air stagnating in the upper space 40 and then blows it down, and the window fan 300 sucks in the air near the floor surface 22 and then blows it up near the window 24, so that the temperature of the perimeter area 50 near the window 24 can be adjusted. Since the temperature of the perimeter area 50 is adjusted, the comfort of the perimeter area can be improved. Furthermore, since the temperature of the perimeter area 50 is adjusted by the ceiling fan 200 and the window fan 300, it is possible to eliminate the need to install a new air conditioner for the perimeter area 50. Furthermore, since it is not necessary to install a new air conditioner for the perimeter area 50, an increase in energy consumption can be suppressed.

[0027] Moreover, the first air inlet 230 is positioned within 300 mm below the ceiling surface 20, so it can draw in warm air. Moreover, the air is blown up along the surface of the window 24, so the effects of outside air can be reduced. Moreover, the window-side fan 300 has an air purification function, so it can purify the air in the living room 10. Moreover, the ceiling fan 200 operates in winter and stops in summer, while the window-side fan 300 operates in both winter and summer, so a comfortable space can be provided regardless of the season.
