Summary of the Invention

Problems to be Solved by the Invention

[0006] In Patent Documents 1 and 2, although a seated person sitting on a furniture body such as a chair can obtain a sense of comfort by air conditioning, simply disposing the furniture body in the air conditioning target space does not necessarily result in obtaining the effect of air conditioning throughout the air conditioning target space, and there is still room for improvement in order to improve the comfort of people existing in the air conditioning target space.

[0007] For example, in an air-conditioned space, the perimeter area near windows tends to experience a large cooling load in the summer and a large heating load in the winter, resulting in a high overall air conditioning load. Therefore, a key issue in air conditioning an air-conditioned space is how to handle the large air conditioning load in the perimeter area.

[0008] Furthermore, when furniture is placed in an air-conditioned space, depending on its location, it may obstruct the occupants of the space, reducing livability, or the furniture itself may stand out, potentially diminishing the aesthetic appeal of the air-conditioned space.

[0009] In light of these circumstances, the main objective of the present invention is to provide an air conditioning system that can provide a sense of comfort through air conditioning throughout the entire space to be air-conditioned, while also enhancing the livability and aesthetic appeal of the space to be air-conditioned. [Means for solving the problem]

[0010] The first characteristic configuration of the present invention is that the space to be air-conditioned is, A furniture body for supplying air, which is seatable, receives conditioned air supplied from an air conditioning unit, and has an outlet that blows the conditioned air out into the surroundings, The furniture is equipped with a seatable section, an intake section for drawing in ambient air, and a return air furniture body that returns the air drawn in by the intake section to the air conditioning unit. The key feature is that the air supply furniture body is located in the perimeter area of ​​the air-conditioned space, while the return air furniture body is located in the area opposite to the perimeter area of ​​the air-conditioned space.

[0011] In this configuration, the air supply furniture is positioned in the perimeter area of ​​the air-conditioned space. As a result, conditioned air is blown out from the outlet of the air supply furniture positioned in the perimeter area, allowing occupants seated on the furniture to experience the comfort of air conditioning, while also effectively handling the air conditioning load in the perimeter area. Furthermore, since the return air furniture is positioned in the area opposite to the perimeter area, the conditioned air blown out from the perimeter area can be circulated throughout the entire air-conditioned space and drawn in from the intake of the return air furniture positioned in the area opposite to the perimeter area.

[0012] This allows for effective handling of the air conditioning load in the perimeter area while circulating conditioned air throughout the entire air-conditioned space, thereby effectively air-conditioning the entire space. This provides a sense of comfort throughout the air-conditioned space and enhances its habitability.

[0013] Furthermore, for example, the furniture unit for supplying air can be placed near a window in the perimeter area, and the furniture unit for returning air can be placed near a wall in the opposite area. This allows the furniture units to be arranged in a way that creates a cohesive and integrated feel within the air-conditioned space, thereby enhancing the aesthetic appeal of the air-conditioned space. In addition, the furniture units do not interfere with the occupants of the air-conditioned space, thus improving the livability of the air-conditioned space without reducing it.

[0014] A second characteristic configuration of the present invention is that the furniture body for supplying air is equipped with a plurality of outlets and an outlet state switching unit that switches the outlet state from which the conditioned air is blown out among the plurality of outlets. The aforementioned airflow state switching unit switches to different airflow states depending on whether it is cooling or heating.

[0015] With this configuration, the airflow state switching unit switches to different airflow states for cooling and heating. Therefore, it can switch to an airflow state suitable for cooling during cooling, and also to an airflow state suitable for heating during heating. As a result, it is possible to switch to the appropriate airflow state in both cooling and heating modes, thereby improving thermal comfort.

[0016] A third characteristic configuration of the present invention is that the furniture body for supplying air is provided with a seating area for a person to sit on and a chamber area disposed below the seating area. The distinguishing feature is that it is equipped with a heating air supply unit that supplies heating air from the air conditioning system to the chamber during heating.

[0017] In this configuration, during heating, the heating air supply unit supplies heating air to the chamber, allowing the seating area to be warmed by the heating air in the chamber. As a result, during heating, the seating area where the occupant sits is warmed, improving the thermal comfort of the occupant.

[0018] A fourth characteristic configuration of the present invention is that the furniture body for return air is equipped with a plurality of suction sections and a suction state switching section that switches the suction state of which of the plurality of suction sections draws in air. The aforementioned intake state switching unit switches to different intake states depending on whether it is cooling or heating.

[0019] With this configuration, the intake state switching unit switches to different intake states for cooling and heating. Therefore, it can switch to an intake state suitable for cooling during cooling, and also switch to an intake state suitable for heating during heating. As a result, it is possible to switch to the appropriate intake state in both cooling and heating modes, thereby improving thermal comfort.

[0020] A fifth characteristic configuration of the present invention is that the suction section includes a suction section for the seating area corresponding to the seating area where a person sits, and a suction section for the feet of the person sitting on the seating area. The furniture body for air return is configured to be switchable between a first installation state in which a first seating part having air permeability is installed as the seating part and a second installation state in which a second seating part having no air permeability is installed as the seating part. The suction state switching part switches to different suction states by switching the furniture body for air return between the first installation state and the second installation state and switching the opening / closing state of the suction part for the feet.

[0021] According to this configuration, the suction state switching part switches to different suction states by switching the furniture body for air return between the first installation state and the second installation state and switching the opening / closing state of the suction part for the feet. Therefore, as a configuration for switching to different suction states, it is only necessary to be equipped with a configuration that allows the seating part to be replaceable between the first seating part and the second seating part and a configuration that opens and closes the suction part for the feet, and the configuration can be simplified.

Embodiments for Carrying Out the Invention

[0023] Embodiments of the air conditioning system according to the present invention will be described based on the drawings. As shown in FIG. 1, this air conditioning system air-conditions the air-conditioned space 1 by using furniture bodies 2 and 3 disposed in the air-conditioned space 1. In addition to the furniture bodies 2 and 3, an air conditioner 4 that generates air for air conditioning for air-conditioning the air-conditioned space 1 is provided.

[0024] As shown in Figures 1 and 2, the furniture unit includes a supply air unit 2 (the furniture unit on the left in Figures 1 and 2) on which a person 5 can sit and which blows conditioned air from the air conditioning unit 4 into the surroundings, and a return air unit 3 (the furniture unit on the right in Figures 1 and 2) on which a person 5 can sit and which draws in ambient air and returns it to the air conditioning unit 4.

[0025] As shown in Figure 1, the conditioned air generated by the air conditioning unit 4 is supplied to the supply air furniture unit 2 through the conditioned air supply passage 41 and blown out from the supply air furniture unit 2 into the air-conditioned space 1. The blown-out conditioned air circulates through the air-conditioned space 1, conditioned the space 1, and is then drawn back into the return air furniture unit 3. The drawn-in air is returned to the air conditioning unit 4 through the air return passage 45.

[0026] As shown in Figure 2, the air supply furniture body 2 is installed in the perimeter area 12 of the air-conditioned space 1, such as near the window 11. For example, the air supply furniture body 2 is installed adjacent to the first wall 14, with its rear air supply portion 21 in contact with the first wall 14 having the window 11. In contrast, the return air furniture body 3 is installed in the opposite area 13 of the air-conditioned space 1, such as the interior area, on the opposite side of the perimeter area 12. The return air furniture body 3 is installed adjacent to the second wall 15, with its rear return air portion 31 in contact with the second wall 15 on the opposite side of the perimeter area 12.

[0027] As shown in Figure 2, the furniture body 2 for supplying air is positioned such that its front-to-back direction (left-to-right direction in Figure 2) is adjacent to and separates from the first wall 14, and is configured so that a person 5 can sit with their back to the first wall 14. The furniture body 2 for supplying air is provided with a rear air supply portion 21 that extends vertically along the first wall 14, and a bottom air supply portion 22 that extends forward from the lower end of the rear air supply portion 21. Both the rear air supply portion 21 and the bottom air supply portion 22 are capable of receiving conditioned air from the air conditioning unit 4, but the rear air supply portion 21 and the bottom air supply portion 22 are provided in a partitioned state, so that there is no airflow of conditioned air between the rear air supply portion 21 and the bottom air supply portion 22.

[0028] As shown in Figure 2, the main body of the air supply furniture 2 is equipped with an air supply backrest 23 located on the front of the rear air supply section 21 and an air supply seat 24 located on the upper surface of the bottom air supply section 22, which serve as seating areas for a person 5.

[0029] The rear air supply section 21 is equipped with an air supply flow section 25 that receives conditioned air from the air conditioning unit 4 and allows the conditioned air to flow from below to above, and a first outlet section 26 (corresponding to an outlet section) that blows the conditioned air that has flowed through the air supply flow section 25 out into the surrounding area. Incidentally, since the air supply flow section 25 receives conditioned air from the air conditioning unit 4, it functions not only as a chamber for circulating conditioned air but also as a chamber for storing conditioned air. The first outlet section 26 is located on the upper surface of the rear air supply section 21 and is configured, for example, as an opening that opens upward. The first outlet section 26 is equipped with a rectifier plate 26a that rectifies the conditioned air flow, causing the conditioned air to be blown upward from the first outlet section 26. Incidentally, although not shown in the diagram, insulating material is placed around the air supply passage section 25 to suppress heat dissipation from the air conditioning air.

[0030] The bottom air supply section 22 is equipped with a chamber section 27 that receives conditioned air from the air conditioning unit 4, and a second outlet section 28 (corresponding to an outlet section) that blows the conditioned air from the chamber section 27 out into the surrounding area. The chamber section 27 is located directly below the air supply seat section 24 on which a person 5 sits, and is positioned adjacent to the entire air supply seat section 24 in the vertical direction. The second outlet section 28 is located on the front of the bottom air supply section 22 so as to correspond to the feet of a person 5 seated on the air supply furniture body 2, and is composed of, for example, multiple holes that open to the front.

[0031] As shown in Figure 2, the air return furniture body 3 is positioned so that its front-to-back direction (left-to-right direction in Figure 2) is adjacent to and separates from the second wall 15, and is configured so that a person 5 can sit with their back to the second wall 15. This allows a person 5 sitting on the air supply furniture body 2 and a person 5 sitting on the air return furniture body 3 to sit facing each other.

[0032] As shown in Figure 2, the furniture body 3 for air return includes a rear air return portion 31 extending vertically along the second wall portion 15, and a bottom air return portion 32 extending forward from the lower end of the rear air return portion 31. The rear air return portion 31 and the bottom air return portion 32 are integrally formed, and an air return passage portion 35 is provided inside to receive and circulate air drawn in from the surroundings.

[0033] As shown in Figures 2 and 3, the main body of the ventilation furniture 3 is equipped with two types of seating areas for a person 5 to sit on: a first seating area 33 (see Figure 2) that is breathable and a second seating area 34 (see the gray area in Figure 3) that is not breathable. By swapping the first seating area 33 and the second seating area 34, the furniture can be switched between a first installation state with the first seating area 33 installed, as shown in Figure 2, and a second installation state with the second seating area 34 installed, as shown in Figure 3.

[0034] As shown in Figure 2, the first seating section 33 is provided with a first backrest section 33a located on the front of the rear air return section 31 and a first seating section 33b located on the upper surface of the bottom air return section 32. Similarly, as shown in Figure 3, the second seating section 34 is provided with a second backrest section 34a located on the front of the rear air return section 31 and a second seating section 34b located on the upper surface of the bottom air return section 32.

[0035] As shown in Figures 2 and 3, the front portion of the rear return air portion 31 and the upper portion of the bottom return air portion 32 are provided with suction sections 36 for the seating area, corresponding to the first seating area 33 and the second seating area 34. The suction sections 36 for the seating area are composed of, for example, multiple holes. As shown in Figure 3, the front portion of the bottom return air portion 32 is provided with a suction section 37 for the feet of a person 5 sitting on the second seating area 34. The suction section 37 for the feet is composed of, for example, multiple holes.

[0036] As shown in Figure 2, the foot-level suction section 37 can be closed by attaching a plate-shaped closing section 39, and the foot-level suction section 37 can be opened and closed by attaching and removing the closing section 39. Incidentally, the configuration for opening and closing the foot-level suction section 37 is not limited to providing a closing section 39 that can be attached to and removed from the foot-level suction section 37, but may also include a manually operated shutter member that can be opened and closed, for example, various manually operated opening and closing members can be applied.

[0037] As shown in Figure 1, the air conditioning system includes an air conditioning air supply passage 41 that supplies conditioned air from the air conditioning unit 4 to the furniture body 2 for supplying air, and an air return passage 45 that returns air from the furniture body 3 for returning air to the air conditioning unit 4. The air conditioning air supply passage 41 is branched downstream into a rear supply passage 42 and a bottom supply passage 43.

[0038] As shown in Figure 2, the rear supply passage 42 is connected to the rear receiving section 21a in the rear air supply section 21, and the bottom supply passage 43 is connected to the bottom receiving section 22a in the bottom air supply section 22, so that conditioned air can be supplied to the rear air supply section 21 and the bottom air supply section 22. The bottom supply passage 43 is equipped with a flow interruption section 44 (for example, a damper) that interrupts the flow of conditioned air, and is configured to be switchable between a supply state in which conditioned air is supplied to the bottom air supply section 22 (see white in Figure 3) and a supply stop state in which the supply of conditioned air to the bottom air supply section 22 is stopped (see black in Figure 2).

[0039] As shown in Figure 1, the air conditioning system is equipped with a control unit 6 that controls the operating state of the air conditioning unit 4 and the opening and closing state of the airflow intermittent unit 44. The air conditioning unit 4 can be, for example, an indoor unit in a heat pump air conditioning system having a refrigerant circuit, but any air conditioning system that can generate conditioned air (cooling air and heating air) is acceptable, and various types of air conditioning systems can be applied.

[0040] The following describes the operation of the air conditioning system, including the air outlet state of the supply air furniture unit 2 and the air intake state of the return air furniture unit 3, during both cooling and heating phases of the air-conditioned space 1.

[0041] (When the air conditioner is on) When cooling the air-conditioned space 1, as shown in Figures 1 and 2, the control unit 6 performs a cooling operation to generate cooling air (conditioned air) in the air conditioning unit 4 and switches the airflow intermittent unit 44 to a closed state. As shown by the dashed line in Figure 1 and the arrows in Figure 2, the cooling air (conditioned air) generated by the air conditioning unit 4 is supplied to the rear air supply section 21 of the air supply furniture body 2 through the air supply air supply passage 41 and the rear supply passage 42. As shown by the white arrows in Figure 2, the cooling air supplied to the rear air supply section 21 flows through the air supply airflow section 25 and is blown upward from the first outlet section 26. This allows the cooling air from the air supply furniture body 2 to flow along the first wall section 14 having the window section 11, and effectively handles the air conditioning load (cooling load) in the perimeter area 12.

[0042] As shown in Figure 2, the furniture body 3 for return air is switched to a first installation state in which a breathable first seating section 33 is installed, and the foot intake section 37 is closed by the closing section 39 to create a closed state. The cooling air blown out from the furniture body 2 for supply air flows through the entire air-conditioned space 1, cooling the air-conditioned space 1, and reaches the furniture body 3 for return air. The furniture body 3 for return air is in the first installation state in which a breathable first seating section 33 is installed, and the foot intake section 37 is closed, so as shown by the arrows in Figure 2, the air that reaches the furniture body 3 for return air passes through the entire first seating section 33 and is drawn into the return air passage section 35 from the entire intake section 36 for the seating section. As a result, a person 5 sitting on the first seating section 33 can feel the coolness of the air (cooling air) with their whole body, improving thermal comfort.

[0043] As shown in Figure 2, the air drawn into the return air passage 35 by the return air furniture body 3 is supplied to the air return passage 45 through the return air communication section 38. The air supplied to the air return passage 45 is returned to the air conditioning unit 4 through the air return passage 45, as shown by the solid arrows in Figure 1.

[0044] (During heating) When heating the air-conditioned space 1, as shown in Figures 1 and 3, the control unit 6 performs a heating operation to generate heating air (air-conditioned air) in the air conditioning unit 4 and switches the airflow intermittent unit 44 to the open state. As shown by the dotted line in Figure 1 and the arrows in Figure 3, the heating air generated by the air conditioning unit 4 is supplied to both the rear air supply section 21 and the bottom air supply section 22 of the furniture body 2 through the air-conditioned air supply passage 41, the rear supply passage 42, and the bottom supply passage 43. As shown by the white arrows in Figure 3, the heating air supplied to the rear air supply section 21 flows through the air supply airflow section 25 and is blown upward from the first outlet section 26. The air-conditioned air supplied to the bottom air supply section 22 is stored in the chamber section 27 and finally blown forward from the second outlet section 28. As shown in Figure 3, the heating air supply unit is composed of a bottom-side supply passage 43, a flow interruption section 44, etc., and the heating air supply unit supplies heating air to the chamber section 27 in the bottom-side air supply section 22 through the bottom-side supply passage 43 by switching the flow interruption section 44 to a supply state.

[0045] This allows the heating air blown out from the first outlet 26 to flow along the first wall 14 having the window 11, effectively handling the air conditioning load (heating load) in the perimeter area 12. Furthermore, the heating air stored in the chamber 27 can warm the air supply seat 24, as indicated by the dotted arrow in Figure 3, and the heating air blown out from the second outlet 28 can warm the feet of the person 5 sitting on the air supply furniture body 2, as indicated by the white arrow in Figure 3, thereby improving the thermal comfort of the person 5.

[0046] As shown in Figure 3, the furniture body 3 for air return is switched to a second installation state in which a second seating section 34 that does not have ventilation is installed, and the closure section 39 of the foot intake section 37 is removed, leaving the foot intake section 37 in an open state. The heating air blown out from the furniture body 2 for supplying air flows through the entire air-conditioned space 1, heating the air-conditioned space 1, and reaches the furniture body 3 for air return. The furniture body 3 for air return is in the second installation state in which a second seating section 34 that does not have ventilation is installed, and the foot intake section 37 is open, so as shown by the arrows in Figure 3, the air that reaches the furniture body 3 for air return does not pass through the second seating section 34, but is drawn in from the foot intake section 37 to the air return passage section 35. As a result, the feet of the person 5 sitting on the second seating section 34 can be warmed, improving thermal comfort.

[0047] As shown in Figure 3, the air drawn into the return air passage 35 by the return air furniture body 3 is supplied to the air return passage 45 through the return air communication section 38. The air supplied to the air return passage 45 is returned to the air conditioning unit 4 through the air return passage 45, as shown by the solid arrows in Figure 1.

[0048] Regarding the air supply furniture unit 2's air supply air outlet state, during cooling, as shown in Figure 2, it switches to a cooling outlet state where air-conditioned air is blown out only from the first outlet 26, and during heating, as shown in Figure 3, it switches to a heating outlet state where air-conditioned air is blown out from both the first outlet 26 and the second outlet 28. Thus, the air conditioning system is equipped with an outlet state switching unit that switches between a cooling outlet state and a heating outlet state, which are different outlet states for cooling and heating. This outlet state switching unit consists of an air supply rear section 21, a rear air supply bottom section 22, a rear supply passage 42, a bottom supply passage 43, a flow interruption section 44, and the like.

[0049] Regarding the intake state of the air conditioning air in the furniture body 3 for return air, during cooling, as shown in Figure 2, it switches to a cooling intake state where air is drawn in from the intake section 36 for the seating area, and during heating, as shown in Figure 3, it switches to a heating intake state where air is drawn in from the intake section 37 for the foot area. Thus, the air conditioning system is equipped with an intake state switching unit that switches between a cooling intake state and a heating intake state, which are different intake states for cooling and heating. This intake state switching unit consists of a first seating section 33, a second seating section 34, a closed section 39, etc. As shown in Figure 2, the intake state switching unit switches the furniture body 3 for return air to a first installation state in which the first seating section 33 is installed and switches the foot area intake section 37 to a closed state, thereby switching to the cooling intake state. As shown in Figure 3, the intake state switching unit switches the furniture body 3 for return air to the second installation state in which the second seating section 34 is installed, and also switches the foot intake section 37 to the open state, thereby switching to the heating intake state.
