Description

Technical Field

[0001] The present invention relates to an air conditioner with a chair function and a booth equipped with the air conditioner with a chair function. More specifically, the present invention relates to an air conditioner with a chair function that can avoid an increase in the cost of the air conditioner and can realize a comfortable working environment for each seated person with low power consumption, and a low-cost and comfortable booth equipped with the air conditioner with a chair function.

Background Art

[0002] In recent years, in order to realize a free working environment in offices, the number of offices adopting a free address system in which fixed seats are not provided on work tables and work is carried out by sitting on available seats according to the work situation has been increasing. In addition, as the forms of co-working offices and shared offices increase, indoor spaces partitioned by partitions and private rooms formed for use by one or more people (hereinafter, also referred to as "booths" including the above indoor spaces and private rooms) also tend to increase. On the other hand, in order to respond to the recent COVID-19 pandemic, telecommuting and telework are encouraged as much as possible, and the number of empty seats in offices tends to increase. Under such circumstances, there is a demand for an air conditioner that can realize a comfortable environment in offices while avoiding an increase in cost and consuming less power. Therefore, for example, the invention of an air conditioning system that divides an air conditioning area in an office space into a plurality of areas and can perform appropriate air conditioning for each air conditioning area according to the state of the person actually sitting in each air conditioning area is disclosed in Patent Document 1.

[0003] In other words, as shown in Figure 18, the air conditioning system 100 disclosed in Patent Document 1 is configured such that an air-conditioned space (office space) 101 is divided into multiple air-conditioned areas 102, and each air-conditioned area 102 is provided with an air conditioning device 103 and multiple chairs 104. The control means 105 is configured to operate and control the air conditioning device 103 according to the occupancy rate, which is the ratio of the number of chairs 104 that are occupied by people to the total number of chairs 104 arranged in the air-conditioned area 102. Each chair 104 is provided with an occupancy detection means 106 that can detect the presence of a seated person in the seated area 104a, and a temperature detection means 107 that can detect the seated temperature, which is the temperature of the seated area 104a. The control means 105 is configured to operate and control the air conditioning device 103 based on the detection results from the occupancy detection means 106 and the temperature detection means 107. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2015-1319 [Overview of the project] [Problems that the invention aims to solve]

[0005] However, the air conditioning system 100 disclosed in the above-mentioned Patent Document 1 had the following problems. Specifically, since it is necessary to install the air conditioning unit 103 on the premise that all chairs 104 placed in the air conditioning area 102 are occupied by people, there was a problem in that the air conditioning unit 103 had to be made larger and more expensive.

[0006] Furthermore, in a work environment where an air-conditioned space (office space) 101 is divided into multiple air-conditioned areas 102, and an air conditioning unit 103 is provided for each air-conditioned area 102, if an indoor space partitioned by partitions or other means, or a private room (booth) formed for use by one or more people is installed in the air-conditioned area 102, there is a problem in that it is difficult to provide comfortable air conditioning in the booth using the air conditioning unit 103. In this case, it is conceivable to install a new air conditioning unit for each booth, but it is not easy to install new air conditioning units and run piping on existing walls, etc., and there are also problems such as increased installation costs.

[0007] Furthermore, each chair 104 is equipped with a seating body detection means 106 capable of detecting the presence of a seated body in the seating area 104a, and a temperature detection means 107 capable of detecting the seating area temperature, which is the temperature of the seating area 104a. The control means 105 operates and controls the air conditioning system 103 based on the detection results from the seating body detection means 106 and the temperature detection means 107. Therefore, it is necessary to provide a seating body detection means 106 and a temperature detection means 107 in all chairs 104. In addition, a control system is required that can transmit signals from the seating body detection means 106 and the temperature detection means 107 to the control means 105 even when the position of the chair 104 is moved. This presented a problem in that the control system, including the chairs 104, would inevitably become more complex and costly.

[0008] Furthermore, since comfort with respect to air conditioning varies depending on the gender, body type, clothing, etc. of the person sitting in the chair 104, the method in which the control means 105 operates and controls the air conditioning unit 103 based on the detection results of the seated person detection means 106 and the temperature detection means 107 presents a problem in that it is difficult to ensure comfort for each person sitting in the chair 104.

[0009] The present invention was made to solve the above problems and aims to provide an air conditioning system with a chair function and a low-cost, comfortable booth equipped with an air conditioning system with a chair function that can avoid the high cost of air conditioning systems and realize a comfortable working environment for each seated person with low power consumption. [Means for solving the problem]

[0010] To achieve the above objective, the air conditioning system with chair function and the booth equipped with the air conditioning system with chair function according to the present invention have the following configuration. (1) An air conditioning system with a chair function, which combines an air conditioning unit that forms harmonious air with a chair, The air conditioning unit is housed inside the chair and is configured to blow the conditioned air outwards from the chair.

[0011] In this invention, the air conditioning unit is housed inside the chair and is configured to blow conditioned air outwards from the chair, allowing the air conditioning unit to move freely around the room with the chair. Therefore, a comfortable working environment can be achieved in various types of offices, such as free-address offices, co-working offices, and shared offices, without the need to install new air conditioning equipment. Furthermore, the air conditioning unit only needs to be small enough to provide air conditioning around the person sitting in the chair, thus avoiding the high cost of air conditioning equipment. In addition, only the air conditioning unit for the chair in which the person is sitting can be operated according to the person's needs, enabling a comfortable working environment for each person with low power consumption.

[0012] Therefore, according to the present invention, it is possible to avoid high costs for air conditioning equipment and provide an air conditioning system with a chair function that can realize a comfortable working environment for each seated person with low power consumption.

[0013] (2) In the air conditioning system with chair function described in (1), The air conditioning unit is housed in a storage compartment formed in the empty space below the seat of the chair. The chair is characterized by having an air outlet formed on its outer periphery that communicates with the air conditioning unit.

[0014] In this invention, the air conditioning unit is housed in a storage compartment formed in the empty space below the seat of the chair, and air vents communicating with the air conditioning unit are formed on the outer perimeter of the chair. This allows for compact housing of the air conditioning unit using the empty space of the chair while maintaining design freedom for the chair. Furthermore, although the weight of the chair increases due to the air conditioning unit, because the air conditioning unit is housed in a storage compartment formed in the empty space below the seat of the chair, the center of gravity of the chair can be positioned lower, allowing the chair to be placed in a balanced manner in the desired location or moved easily. In addition, since air vents communicating with the air conditioning unit are formed on the outer perimeter of the chair, comfortable conditioned air can be supplied to the person sitting in the chair simply by forming the air vents at an appropriate position on the outer perimeter of the chair.

[0015] (3) In an air conditioning system with a chair function as described in (1) or (2), The aforementioned air conditioning unit comprises a cooling unit that blows out cool air and a warming unit that blows out warm air, separated by a partition wall. The cooling unit is located above the partition wall and communicates with an upper air outlet formed on the outer periphery of the upper side of the chair. The warming unit is located below the partition wall and is in communication with a lower air outlet formed on the outer periphery of the underside of the chair.

[0016] In this invention, the air conditioning unit comprises a cooling unit for supplying cool air and a warming unit for supplying warm air, separated by a partition wall. The cooling unit is located above the partition wall and communicates with an upper air outlet formed on the outer circumference of the upper side of the chair, while the warming unit is located below the partition wall and communicates with a lower air outlet formed on the outer circumference of the lower side of the chair. As a result, cool air can be efficiently supplied from the cooling unit to the upper side of the chair where warm air tends to accumulate, and warm air can be efficiently supplied from the warming unit to the lower side of the chair where cool air tends to accumulate. Therefore, a more comfortable working environment can be achieved for the person sitting in the chair.

[0017] (4)(3) In the air conditioning system with chair function described above, The air conditioning unit includes a compressor, a condenser, an expansion valve, an evaporator, and pipes connecting these in sequence, and consists of a heat pump that circulates refrigerant within the pipes. The cold air unit is provided with a first blower fan that blows conditioned air passing through the evaporator to the upper air outlet. The heating unit is characterized by being provided with a second blower fan that blows conditioned air passing through the condenser to the lower air outlet.

[0018] In the present invention, since the air conditioning unit includes a compressor, a condenser, an expansion valve, an evaporator, and pipes connecting these in sequence, and consists of a heat pump that circulates refrigerant within the pipes, the air conditioning unit can be formed compactly, and the functions of heating and cooling can be efficiently realized with low power consumption.

[0019] Also, since the cold air unit is provided with a first blower fan that blows conditioned air passing through the evaporator to the upper air outlet, the first blower fan can send out the conditioned air cooled by the refrigerant cooled by the expansion valve absorbing the heat of the air passing through the evaporator from the upper air outlet to the outer peripheral part above the chair, and can effectively lower the temperature around the head of the seated person.

[0020] Also, since the heating unit is provided with a second blower fan that blows conditioned air passing through the condenser to the lower air outlet, the second blower fan can send out the conditioned air heated by the refrigerant heated by the compressor releasing heat to the air passing through the condenser from the lower air outlet to the outer peripheral part below the chair, and can effectively raise the temperature around the feet of the seated person. Therefore, a more comfortable working environment can be realized for the seated person sitting on the chair.

[0021] (5) In the air conditioning device with chair functions described in (2), the air conditioning unit includes a blowing unit that blows cold air or warm air, and an exhaust air unit that blows exhaust heat air, separated by a partition wall. The air supply unit is located above the partition wall and is communicated with an upper air supply port formed on the outer peripheral portion of the upper side of the chair. The exhaust air unit is located below the partition wall and is communicated with a lower air supply port formed on the outer peripheral portion of the lower side of the chair, which is characterized by this.

[0022] In the present invention, the air conditioning unit includes an air supply unit for blowing cold air or warm air and an exhaust air unit for blowing exhaust heat air, separated by a partition wall. The air supply unit is located above the partition wall and is communicated with an upper air supply port formed on the outer peripheral portion of the upper side of the chair. The exhaust air unit is located below the partition wall and is communicated with a lower air supply port formed on the outer peripheral portion of the lower side of the chair. Therefore, it is possible to efficiently blow conditioned air of cold air or warm air from the air supply unit to the upper body side of the seated person sitting on the upper side of the chair, and also to discharge unnecessary exhaust heat air from the exhaust air unit at the foot side of the seated person. Thus, a more comfortable working environment can be realized for the seated person sitting on the chair.

[0023] (6)(5) In the air conditioning device with a chair function described above, The air conditioning unit includes a compressor, an air supply heat exchanger, an expansion valve, an exhaust air heat exchanger, a four-way valve, pipes connecting these, and a refrigerant flowing in the pipes, and is composed of a heat pump formed such that the flow direction of the refrigerant can be switched by the four-way valve. The air supply unit includes a first blower fan for blowing cold air or warm air passing through the air supply heat exchanger to the upper air supply port. The exhaust air unit includes a second blower fan for blowing exhaust heat air passing through the exhaust air heat exchanger to the lower air supply port, which is characterized by this.

[0024] In the present invention, the air conditioning unit consists of a heat pump comprising a compressor, a blower heat exchanger, an expansion valve, an exhaust heat exchanger, a four-way valve, piping connecting these, and a refrigerant flowing through the piping, with the direction of refrigerant flow being switchable by the four-way valve. The blower unit is equipped with a first blower fan that blows cold or warm air passing through the blower heat exchanger to the upper air outlet, and the exhaust unit is equipped with a second blower fan that blows exhaust hot air passing through the exhaust heat exchanger to the lower air outlet. As a result, the air conditioning unit can be made compact, and heating and cooling functions can be efficiently realized with low power consumption.

[0025] Furthermore, the air conditioning unit consists of a heat pump configured to allow switching of the refrigerant flow direction by a four-way valve, and the blower unit is equipped with a first blower fan that blows cold or warm air passing through the blower heat exchanger to the upper air outlet. Therefore, during cooling, the first blower fan can send the cooled air, which has been cooled by the low-pressure, low-temperature refrigerant absorbing the heat of the air being blown into the blower heat exchanger through which the refrigerant flows, to the upper side of the chair from the upper air outlet, effectively lowering the temperature (room temperature) around the upper body of the seated person. Also, during heating, when the direction of refrigerant flow is switched by the four-way valve, the first blower fan can send the warm air, which has been heated by the high-pressure, high-temperature refrigerant heating the air being blown into the blower heat exchanger through which the refrigerant flows, to the upper side of the chair from the upper air outlet, effectively raising the temperature (room temperature) around the upper body of the seated person.

[0026] Furthermore, the exhaust unit is equipped with a second fan that blows the exhaust heat air passing through the exhaust heat exchanger to the lower air outlet. Therefore, during cooling, the second fan releases the unwanted exhaust heat air, which is heated by the high-pressure, high-temperature refrigerant flowing through the exhaust heat exchanger, to the underside of the chair through the lower air outlet, thereby maintaining an appropriate temperature (room temperature) around the occupant's upper body. Also, during heating, when the direction of refrigerant flow is switched by a four-way valve, the second fan releases the unwanted exhaust heat air, which is cooled by the low-pressure, low-temperature refrigerant flowing through the exhaust heat exchanger, to the underside of the chair through the lower air outlet, thereby maintaining an appropriate temperature (room temperature) around the occupant's upper body. As a result, an even more comfortable working environment can be achieved for occupants sitting in the chair.

[0027] In the air conditioning system with chair function described in (7)(6), The system comprises a first drain pan located below the blower heat exchanger, a second drain pan connected downstream to the first drain pan and located below the exhaust heat exchanger, and a drain pool connected downstream to the second drain pan, having a heater device and located in the exhaust hot air blowing path. The condensed water accumulated in the first drain pan is collected in the drain pool via the second drain pan, and the drain water collected in the drain pool is evaporated by the heater device.

[0028] In this invention, a first drain pan is provided below the blower heat exchanger, a second drain pan is provided below the exhaust heat exchanger and connected downstream to the first drain pan, and a drain pool is provided downstream to the second drain pan and has a heater device, and is located in the exhaust air blowing path. Condensed water accumulated in the first drain pan is collected in the drain pool via the second drain pan, and the drain water collected in the drain pool is evaporated by the heater device. Therefore, the drain water generated when the air conditioning unit is operated can be automatically vaporized and released to the outside with the exhaust air. As a result, there is no need to install a tank for storing drain water or a drain pipe for drain water, and this air conditioning unit with chair function can be moved to any position, further enhancing convenience.

[0029] Furthermore, the condensed water accumulated in the first drain pan is collected in the drain pool via the second drain pan, and the drain water collected in the drain pool is evaporated by a heater. For example, during cooling, the condensed water that accumulates in the first drain pan due to condensation on the blower heat exchanger through which low-pressure, low-temperature refrigerant flows is heated by the exhaust heat exchanger through which high-pressure, high-temperature refrigerant flows as it passes through the second drain pan, and is collected in the drain pool as heated drain water. As a result, the drain water collected in the drain pool can be quickly boiled and evaporated by the heater. Consequently, the drain water can be efficiently evaporated with less power consumption.

[0030] In an air conditioning system with a chair function as described in (8)(6) or (7), The front legs of the chair are provided with a partition plate that forms a heel relief portion into which the seated person's heel can be inserted into the storage compartment. The partition plate is characterized by having an air inlet formed therein for air passing through the heat exchanger for blowing air.

[0031] In this invention, the front legs of the chair are equipped with a partition plate that forms a heel relief portion into which the seated person's heel can be inserted. The partition plate has an air inlet for air passing through the heat exchanger for ventilation. As a result, when a seated person stands up from the chair, they can insert their heel into the heel relief portion, bending their knees to an angle of 90 degrees or less, and easily stand up. For example, even in a small room, a seated person in this air conditioning unit with chair functionality can easily stand up, further enhancing convenience.

[0032] (9) A booth equipped with an air conditioning unit with a chair function as described in any one of (1) to (4), The booth is characterized in that it has an indoor space in which one or more seated persons can work or reside while sitting in the air-conditioned unit with chair function, and is formed to be partitioned by side wall panels that surround the outer perimeter of the air-conditioned unit with chair function from at least three directions.

[0033] In this invention, a booth equipped with an air conditioning unit with a chair function has an indoor space where one or more seated persons can work or reside, and is formed so that the perimeter of the air conditioning unit with a chair function can be partitioned by side wall panels surrounding it from at least three directions. Therefore, the air conditioning inside the booth can be kept at a comfortable temperature using only the air conditioning unit of the air conditioning unit with a chair function where the seated persons sit. As a result, there is no need to install a new air conditioning unit for each booth, and the high cost of air conditioning can be avoided. Furthermore, since the booth is formed so that the air conditioning unit with a chair function can be partitioned by side wall panels surrounding it on at least three sides, the side wall panels can prevent conditioned air from escaping outside the booth, further reducing the power consumption of the air conditioning unit. As a result, a low-cost and comfortable booth equipped with an air conditioning unit with a chair function can be provided.

[0034] At the booths listed in (10)(9), The booth is characterized by having a floor plate on which an air conditioning unit with a chair function is mounted at a position spaced apart from the floor surface, and having an openable and closable ventilation window formed in the floor plate at a position adjacent to the lower end of the chair.

[0035] In this invention, the booth is equipped with a floor plate on which an air conditioning unit with a chair function is mounted at a position spaced apart from the floor surface. The floor plate has an openable and closable ventilation window located adjacent to the lower end of the chair. This allows for maintaining a comfortable air conditioning level inside the booth while stale conditioned air to escape through the ventilation window and be replaced with fresh air. As a result, a comfortable booth can be provided at a low cost while suppressing an increase in the power consumption of the air conditioning unit.

[0036] A booth equipped with an air conditioning unit with a chair function as described in any one of (11)(6) to (8), The booth is characterized in that it has an indoor space in which one or more seated persons can work or reside while sitting in the air-conditioned unit with chair function, and is formed to be partitioned by side wall panels that surround the outer perimeter of the air-conditioned unit with chair function from at least three directions.

[0037] In this invention, a booth equipped with an air conditioning unit with a chair function has an indoor space where one or more seated persons can work or reside, and is formed so that the perimeter of the air conditioning unit with a chair function can be partitioned by side wall panels surrounding it from at least three directions. Therefore, the air conditioning inside the booth can be kept at a comfortable temperature using only the air conditioning unit of the air conditioning unit with a chair function where the seated persons sit. As a result, there is no need to install a new air conditioning unit for each booth, and the high cost of air conditioning can be avoided. Furthermore, since the booth is formed so that the air conditioning unit with a chair function can be partitioned by side wall panels surrounding it on at least three sides, the side wall panels can prevent conditioned air from escaping outside the booth, further reducing the power consumption of the air conditioning unit. As a result, a low-cost and comfortable booth equipped with an air conditioning unit with a chair function can be provided.

[0038] (12)(11) At the booths listed, The aforementioned side wall panel is formed to surround the outer periphery of the air conditioning unit with chair function from four directions. The booth is equipped with a ceiling panel connected to the upper end of each of the side wall panels. The upper air outlet is characterized in that it is formed to blow cool or warm air diagonally upward and backward from the upper end of the backrest of the chair.

[0039] In this invention, the side walls are formed to surround the outer perimeter of the air conditioning unit with chair function from four directions, the booth is equipped with a ceiling panel connected to the upper end of each side wall, and the upper air outlet is formed to blow cool or warm air diagonally upward and backward from the upper end of the chair's backrest. As a result, the cool or warm air blown from the upper air outlet can rise along the side walls of the booth toward the ceiling panel and diffuse into the interior space via the ceiling panel. Therefore, even in a narrow booth, the discomfort of the cool or warm air blown from the upper air outlet directly touching the seated person can be avoided, and the air conditioning inside the booth can be kept more uniform and comfortable.

[0040] (13)(12) At the booths listed, The booth is provided with a floor plate on which the air conditioning unit with chair function is placed at a position spaced apart from the floor surface, and the floor plate is characterized in that an inlet window is formed adjacent to the lower end of the chair to introduce air passing through the exhaust heat exchanger from the floor surface side, and an exhaust window is formed to discharge the exhaust hot air that has passed through the exhaust heat exchanger to the floor surface side.

[0041] In this invention, the booth is equipped with a floor plate on which an air conditioning unit with a chair function is mounted at a position separated from the floor surface. The floor plate has an inlet window adjacent to the lower end of the chair, which introduces air passing through an exhaust heat exchanger from the floor side, and an exhaust window which discharges the exhaust heat air that has passed through the exhaust heat exchanger to the floor side. As a result, air from outside the booth can be introduced through the inlet window of the floor plate, and the exhaust heat air that has passed through the exhaust heat exchanger can be released outside the booth through the exhaust window. Therefore, by separating the conditioned air inside the booth from the unnecessary exhaust heat air, the power consumption of the air conditioning unit can be reduced, and the air conditioning inside the booth can be kept in a comfortable state. As a result, a comfortable booth can be provided at a low cost while suppressing an increase in the power consumption of the air conditioning unit.

[0042] (14)(13) At the booths listed, The lower surface of the floor plate is provided with an air partition plate that restricts the airflow path for air introduced into the inlet window, and an exhaust partition plate that restricts the airflow path for exhaust heat air discharged from the exhaust window. The openings of the air partition plate and the exhaust partition plate are formed facing opposite directions.

[0043] In this invention, the underside of the floor plate is provided with an air partition plate that restricts the airflow path for air introduced into the intake window and an exhaust partition plate that restricts the airflow path for exhaust hot air discharged from the exhaust window. The openings of the air partition plate and the exhaust partition plate are formed facing opposite directions, thereby preventing the air introduced into the intake window and the exhaust hot air discharged from the exhaust window from mixing below the floor plate. As a result, the heat exchange efficiency in the exhaust heat exchanger can be improved, and the air conditioning inside the booth can be kept at a comfortable level with less power consumption.

[0044] In the booths listed in (15), (13), or (14), A moisture-regulating sheet material, which is larger than the exhaust window, is placed on the floor surface facing the exhaust window.

[0045] In this invention, a humidity-regulating sheet material, which is larger than the exhaust window, is placed on the floor surface facing the exhaust window. As a result, the humidity-regulating sheet material absorbs moisture contained in the exhaust hot air and releases it to the outside, thereby preventing condensation on the floor surface. In other words, in this booth, water vapor produced when drain water accumulated in the drain pool of the air conditioning unit with chair function is evaporated by the heater device is discharged from the exhaust window along with the exhaust hot air, potentially causing condensation on the floor surface. However, since a humidity-regulating sheet material, which is larger than the exhaust window, is placed on the floor surface facing the exhaust window, the humidity-regulating sheet material absorbs moisture contained in the exhaust hot air and releases it into the outside air from a point away from the exhaust window, thereby preventing condensation on the floor surface.

[0046] A booth equipped with an air conditioning unit with a chair function as described in any one of (16)(1) to (8), The booth is characterized in that it has an indoor space in which one or more seated persons can work or reside while sitting in the air-conditioned unit with chair function, and is partitioned by a floor member on which the air-conditioned unit with chair function is placed, a frame member extending upward from the outer edge of the floor member, and a sheet member covering the frame member.

[0047] In this invention, a booth equipped with an air conditioning unit with a chair function has a space for one or more seated persons to work or live in, and is formed to be partitioned by a floor member on which the air conditioning unit with a chair function is placed, a frame member extending upward from the outer edge of the floor member, and a sheet member covering the frame member. Therefore, the air conditioning inside the booth can be kept at a comfortable temperature using only the air conditioning unit of the air conditioning unit with a chair function on which the seated persons sit. As a result, there is no need to install a new air conditioning unit for each booth, and the high cost of air conditioning can be avoided. Furthermore, since the booth is partitioned by a floor member on which the air conditioning unit with a chair function is placed, a frame member extending upward from the outer edge of the floor member, and a sheet member covering the frame member, the booth can be made lighter and can be easily installed not only indoors but also outdoors. In addition, the sheet member covering the frame member can easily prevent conditioned air from escaping outside the booth, and the power consumption of the air conditioning unit can be reduced at a lower cost. As a result, a low-cost and comfortable booth equipped with an air conditioning unit with a chair function can be provided. [Effects of the Invention]

[0048] According to the present invention, it is possible to avoid the high cost of air conditioning equipment and to provide an air conditioning system with a chair function that can create a comfortable working environment for each seated person with low power consumption, as well as a low-cost, comfortable booth equipped with an air conditioning system with a chair function.

[0050] Next, an air conditioning system with a chair function and a booth equipped with such an air conditioning system will be described in detail with reference to the drawings, according to one aspect of this embodiment. First, the structure and operation method of the air conditioning system with a chair function according to the first and second embodiments of this embodiment will be described, and then the booths of the first to third embodiments equipped with such air conditioning system will be described.

[0051] <Structure and operation method of the air conditioning unit with chair function according to the first embodiment> First, the structure and operation method of the air conditioning system with chair function according to the first embodiment of this embodiment will be explained using Figures 1 to 5. Figure 1 shows a schematic cross-sectional view of the air conditioning system with chair function according to the first embodiment of this embodiment. Figure 2 shows the AA cross-sectional view shown in Figure 1. Figure 3 shows the BB cross-sectional view shown in Figure 1.

[0052] As shown in Figures 1 to 5, the chair-equipped air conditioning device 10 of this first embodiment is a chair-equipped air conditioning device 10 in which an air conditioning unit 2 that forms conditioned air TK and a chair 1 are combined. The air conditioning unit 2 is housed inside 1N of the chair 1 and is configured to blow conditioned air TK toward the outside 1G of the chair 1. The air conditioning unit 2 is housed in a storage chamber 12 formed in the empty space below the seating portion 11 of the chair 1. An air outlet 14 is formed on the outer circumference 13 of the chair 1, which communicates with the air conditioning unit 2.

[0053] Here, chair 1 is equipped with a seating area 11 on which the occupant TZ sits, a backrest 15 that stands upright behind the seating area 11, and legs 16 that surround the entire side of the storage compartment 12 below the seating area 11. However, it is not necessary to have a backrest 15, or the backrest 15 can be folded down to be used as a bed (bedding). Note that this chair 1 includes a bed (bedding) with a wide seating area 11. The legs 16 are fitted with casters 17 that are formed to move on the floor surface FL, but fixing protrusions may be fitted instead of casters 17. The air vents 14 are formed at the upper end 151 of the backrest area 15 and the lower end 18 of the legs 16, but are not limited to these, and the air vents 14 may be formed at appropriate positions on the outer circumference 13 of chair 1.

[0054] As described above, the air conditioning unit 2 is housed inside chair 1 (1N) and is configured to blow conditioned air TK outwards (1G) from chair 1, allowing the air conditioning unit 2 to move freely within the room together with chair 1. Therefore, a comfortable working environment can be achieved in various types of offices, such as free-address offices, co-working offices, and shared offices, without the need to install new air conditioning equipment. Furthermore, the air conditioning unit 2 only needs to be small enough to provide air conditioning around the person sitting in chair 1, thus avoiding the high cost of air conditioning equipment. In addition, only the air conditioning unit 2 for the chair 1 that the person is sitting in can be operated according to the person's needs, enabling a comfortable working environment for each person with low power consumption. Moreover, convenience can be enhanced by operating the air conditioning unit 2 with a remote control.

[0055] Furthermore, the air conditioning unit 2 is housed in a storage compartment 12 formed in the empty space below the seat 11 of the chair 1, and an air outlet 14 communicating with the air conditioning unit 2 is formed on the outer perimeter 13 of the chair 1. This allows for compact housing of the air conditioning unit 2 using the empty space of the chair 1 while maintaining design freedom for the chair 1. In addition, although the weight of the chair 1 increases due to the air conditioning unit 2, because the air conditioning unit 2 is housed in the storage compartment 12 formed in the empty space below the seat 11 of the chair 1, the center of gravity of the chair 1 can be positioned lower, allowing the chair 1 to be placed in the desired position in a balanced manner or moved easily. Also, since an air outlet 14 communicating with the air conditioning unit 2 is formed on the outer perimeter 13 of the chair 1, comfortable conditioned air can be supplied to each person sitting in the chair 1 simply by positioning the air outlet 14 appropriately.

[0056] Furthermore, the air conditioning unit 2 preferably comprises a cooling unit 21 that blows cool air TK1 and a warming unit 22 that blows warm air TK2, separated by a partition wall 27. The cooling unit 21 is located above the partition wall 27 and communicates with an upper air outlet 14a formed on the upper outer periphery 13a of the chair 1, while the warming unit 22 is located below the partition wall 27 and communicates with a lower air outlet 14b formed on the lower outer periphery 13b of the chair 1.

[0057] In this case, the cool air TK1 supplied by the cool air unit 21 and the warm air TK2 supplied by the warm air unit 22 are separated by the partition wall 27. This allows the cool air unit 21 to efficiently supply cool air TK1 to the upper side of the chair 1 where warm air tends to accumulate, and the warm air unit 22 to efficiently supply warm air TK2 to the lower side of the chair 1 where cool air tends to accumulate. As a result, a more comfortable working environment can be created for the person sitting in the chair 1, TZ.

[0058] Here, the upper air outlet 14a for blowing in the cool air TK1 is formed at the upper end 151 of the backrest 15, but it is not limited to this, and may be formed at various positions, for example, on the seating side of the seat 11 or on the backrest side of the backrest 15. The upper air outlet 14a may be covered with a breathable surface material. Furthermore, an on / off valve or adjustment valve may be provided for the upper air outlets 14a formed at various positions, and each upper air outlet 14a may be made open / closed or the airflow adjustable via an operating lever or the like. With the above configuration, an even more comfortable working environment can be realized according to the preferences of the person sitting in the chair 1, TZ.

[0059] Furthermore, the air conditioning unit 2 does not need to be particularly limited as long as it can supply cold air TK1 and warm air TK2 at appropriate temperatures. However, as shown in Figures 1 to 4, it is preferable that the unit consists of a heat pump HP having a compressor 23, a condenser 221, an expansion valve 243, an evaporator 211, and piping 241 connecting these in order, and circulating a refrigerant 242 in the piping 241. The cold air unit 21 is equipped with a first blower fan 251 that blows conditioned air (cold air TK1) passing through the evaporator 211 to the upper air outlet 14a, and the warm air unit 22 is equipped with a second blower fan 252 that blows conditioned air (warm air TK2) passing through the condenser 221 to the lower air outlet 14b.

[0060] The compressor 23 is a device that compresses the gasified refrigerant 242 to high pressure and high temperature before sending it out. The condenser 221 is a heat exchanger that liquefies the gasified refrigerant 242 and releases heat to the outside. The expansion valve 243 is a valve body that rapidly expands the liquefied refrigerant 242 to low pressure and low temperature. The evaporator 211 is a heat exchanger that absorbs heat from the outside and evaporates the low-pressure, low-temperature refrigerant 242. The condenser 221 and the evaporator 211 are equipped with drain pans 28 that receive water droplets during heat exchange. In addition, a heater device (for example, a PTC heater) 281 is placed in the drain pan 28 of the condenser 221 to evaporate the accumulated drain water.

[0061] Furthermore, an air intake for the first blower fan 251 is formed in the leg portion 16 located in front of the seat portion 11, and a filter 261 is detachably attached to this air intake. Additionally, an air intake for the second blower fan 252 is formed in the lower end portion 18 of the leg portion 16, and another filter 262 is detachably attached to this air intake.

[0062] In this case, the air conditioning unit 2 comprises a compressor 23, a condenser 221, an expansion valve 243, an evaporator 211, and piping 241 connecting these in order, and consists of a heat pump HP that circulates refrigerant 242 in the piping 241. As a result, the air conditioning unit 2 can be made compact, and heating and cooling functions can be efficiently realized with low power consumption. The air conditioning unit 2 may be configured to be powered from an external power source via a power cord, or it may be configured to be powered via a contactless power supply device.

[0063] Furthermore, the cooling unit 21 is equipped with a first blower fan 251 that blows conditioned air TK passing through the evaporator 211 to the upper air outlet 14a. As a result, the conditioned air (cold air TK1), which has been cooled by the refrigerant 242 cooled by the expansion valve 243 absorbing heat from the air passing through the evaporator 211, can be sent by the first blower fan 251 from the upper air outlet 14a to the upper outer circumference 13a of the chair 1, thereby effectively lowering the temperature around the head of the seated person TZ.

[0064] Furthermore, the warming unit 22 is equipped with a second blower fan 252 that blows conditioned air TK passing through the condenser 221 to the lower air outlet 14b. As a result, the refrigerant 242 heated by the compressor 23 releases heat into the air passing through the condenser 221, and the heated conditioned air (warm air TK2) is then blown by the second blower fan 252 from the lower air outlet 14b to the lower outer circumference 13b of the chair 1, effectively raising the temperature around the feet of the seated person TZ. Therefore, a more comfortable working environment can be achieved for the seated person TZ sitting in the chair 1.

[0065] Specifically, the cooling unit 21 and the warming unit 22 are operated as shown in Figure 5(A) during cooling and as shown in Figure 5(B) during heating. That is, during cooling, as shown in Figure 5(A), the first blower fan 251 operates to draw in ambient air from the air intake (filter 261) of the leg portion 16 located in front of the seat portion 11 and blow it to the evaporator 211. The first blower fan 251 then sends the conditioned air (cold air TK1), which has been cooled by the refrigerant 242 absorbing heat in the evaporator 211, out from the upper air outlet 14a to the upper outer circumference 13a of the chair 1. The conditioned air (cold air TK1) sent out can effectively lower the temperature around the head of the seated person TZ.

[0066] On the other hand, even during cooling, the second blower fan 252 may operate to draw in ambient air from the air intake (filter 262) at the lower end 18 of the leg portion 16 and blow it to the condenser 221. The second blower fan 252 then sends the heated conditioned air TK, which is produced when the refrigerant 242 releases heat in the condenser 221, from the lower air outlet 14b to the outer periphery 13b of the underside of the chair 1. The conditioned air (warm air TK2) that is sent out is diffused around the chair 1 from the lower end 18 of the leg portion 16 of the chair 1, so as not to interfere with the comfortable air conditioning environment for the seated person TZ.

[0067] Furthermore, during heating, as shown in Figure 5(B), the first blower fan 251 operates in the opposite direction to that during cooling, blowing air that has passed through the evaporator 211 from the air intake (filter 261) of the leg portion 16 located in front of the seat portion 11. The refrigerant 242 absorbs heat from the air passing through the evaporator 211. The air blown from the air intake (filter 261) of the leg portion 16 is then drawn in from the air intake (filter 262) by the second blower fan 252.

[0068] On the other hand, during heating, the second blower fan 252 operates in the same direction as during cooling, drawing in ambient air (including air blown in from the air intake (filter 261)) from the air intake (filter 262) at the lower end 18 of the leg portion 16 and blowing it to the condenser 221. The second blower fan 252 sends the heated conditioned air TK, which is heated by releasing the heat of the refrigerant 242 heated by the compressor 23 in the condenser 221, out from the lower air outlet 14b to the outer periphery 13b on the underside of the chair 1. The sent-out conditioned air (warm air TK2) is diffused from the lower end 18 of the leg portion 16 of the chair 1 to the area around the chair 1, creating a comfortable air-conditioned environment near the feet of the seated person TZ.

[0069] <Structure and operation method of the air conditioning unit with chair function in the second embodiment> Next, the structure and operation method of the air conditioning system with chair function according to the second embodiment of this embodiment will be described using Figures 6 to 10. Figure 6 shows a schematic cross-sectional view of the air conditioning system with chair function according to the second embodiment of this embodiment. Figure 7 shows a perspective cross-sectional view of the air conditioning system with chair function shown in Figure 6. Figure 8 shows a perspective cross-sectional view of the air conditioning unit in the air conditioning system with chair function shown in Figure 6. Figure 9 is a schematic system configuration diagram of the air conditioning unit in the air conditioning system with chair function shown in Figure 6, showing the operating state during cooling. Figure 10 is a schematic system configuration diagram of the air conditioning unit in the air conditioning system with chair function shown in Figure 6, showing the operating state during heating.

[0070] As shown in Figures 6 to 10, the chair-equipped air conditioning device 10B of this second embodiment is a chair-equipped air conditioning device 10B in which an air conditioning unit 2B that forms conditioned air TK and a chair 1B are combined. The air conditioning unit 2B is housed inside 1BN of the chair 1B and is configured to blow conditioned air TK toward the outside 1BG of the chair 1B. The air conditioning unit 2B is housed in a storage chamber 12B formed in the empty space below the seating portion 11B of the chair 1B. An air outlet 14B is formed on the outer periphery 13B of the chair 1B and communicates with the air conditioning unit 2B.

[0071] Here, as in the first embodiment, the chair 1B includes a seat 11B on which the occupant TZ sits, a backrest 15B that stands upright behind the seat 11B, and legs 16B that surround the entire side of the storage compartment 12B below the seat 11B. However, it is not necessary to have a backrest 15B, or the backrest 15B can be folded down to be used as a bed (bedding). This chair 1B includes a bed (bedding) with a wide seat 11B. The legs 16B are fitted with casters 17B that are formed to move on the floor surface FL, but fixing protrusions may be fitted instead of casters 17B. Also, cushion members are fitted to the seat 11B and backrest 15B, but cushion members are not necessary. Furthermore, although the air vents 14B are formed at the upper end 151B of the backrest portion 15B and the lower end 18B of the leg portion 16B, the chair is not limited to this, and the air vents 14B may be formed at an appropriate position on the outer circumference 13B of the chair 1B.

[0072] As described above, the air conditioning unit 2B is housed inside chair 1BN and is configured to blow conditioned air TK outwards from chair 1BG, allowing the air conditioning unit 2B to move freely within the room together with chair 1B. Therefore, a comfortable working environment can be achieved in various types of offices, such as free-address offices, co-working offices, and shared offices, without the need to install new air conditioning equipment. Furthermore, the air conditioning unit 2B only needs to be small enough to provide air conditioning around the occupant TZ sitting in chair 1B, thus avoiding the high cost of air conditioning equipment. In addition, only the air conditioning unit 2B of the chair 1B where the occupant TZ is sitting can be operated as needed by the occupant TZ, enabling a comfortable working environment for each occupant TZ with low power consumption. Convenience can also be enhanced by operating the air conditioning unit 2B with a remote control.

[0073] Furthermore, the air conditioning unit 2B is housed in a storage compartment 12B formed in the empty space below the seat 11B of the chair 1B, and an air outlet 14B communicating with the air conditioning unit 2B is formed on the outer perimeter 13B of the chair 1B. This allows for compact housing of the air conditioning unit 2B using the empty space of the chair 1B while maintaining design freedom for the chair 1B. In addition, although the weight of the chair 1B increases due to the air conditioning unit 2B, because the air conditioning unit 2B is housed in the storage compartment 12B formed in the empty space below the seat 11B of the chair 1B, the center of gravity of the chair 1B can be positioned lower, allowing the chair 1B to be placed in the desired position in a balanced manner or moved easily. Also, since an air outlet 14B communicating with the air conditioning unit 2B is formed on the outer perimeter 13B of the chair 1B, comfortable conditioned air TK can be supplied to each occupant B sitting in the chair 1B simply by positioning the air outlet 14B appropriately.

[0074] Furthermore, in the air conditioning system with chair function 10B of this second embodiment, the air conditioning unit 2B is preferably equipped with a blowing unit 21B that blows cold air TK1 or warm air TK2 and an exhaust unit 22B that blows exhaust hot air HN, separated by a partition wall 27B, wherein the blowing unit 21B is located above the partition wall 27B and communicates with an upper air outlet 14Ba formed on the upper outer periphery 13Ba of the chair 1B, and the exhaust unit 22B is located below the partition wall 27B and communicates with a lower air outlet 14Bb formed on the lower outer periphery 13Bb of the chair 1B.

[0075] In this case, the ventilation unit 21B can efficiently supply conditioned air TK, either cool air TK1 or warm air TK2, to the upper body of the occupant TZ sitting on the upper side of chair 1B, and the exhaust unit 22B can release unwanted exhaust hot air HN at the occupant TZ's feet. Therefore, a more comfortable working environment can be achieved for the occupant TZ sitting on chair 1B. The partition wall 27B is formed so that the airflow path for supplying cool air TK1 or warm air TK2 by the ventilation unit 21B and the airflow path for supplying exhaust hot air HN by the exhaust unit 22B are separated vertically in a Y-shape.

[0076] Here, the upper air outlet 14Ba for blowing in cold air TK1 or warm air TK2 is formed at the upper end 151B of the backrest 15B. The upper air outlet 14Ba is formed to blow in a diagonal upward and backward direction, and is elongated in the width direction of the backrest 15B, but is not limited to this. The upper air outlet 14Ba may be formed at various positions, for example, on the seating side of the seating section 11B or on the backrest side of the backrest 15B, and in that case, it may be covered with a breathable surface material. Furthermore, an on / off valve or adjustment valve may be provided for the upper air outlets 14Ba formed at various positions, and each upper air outlet 14Ba may be made open / closed or the airflow adjustable via an operating lever or the like. With the above configuration, an even more comfortable working environment can be realized according to the preferences of the person sitting in the chair 1B, TZ.

[0077] Furthermore, in this air conditioning system with chair function 10B, the air conditioning unit 2B does not need to be particularly limited as long as it can blow out cold air TK1 and warm air TK2 at appropriate temperatures. For example, as shown in Figures 6 to 10, the air conditioning unit 2B has a compressor 23B, a heat exchanger for blowing air 211B, an expansion valve 243B, a heat exchanger for exhaust air 221B, a four-way valve 244B, piping 241B connecting these, and a refrigerant 242 flowing through the piping 241B. Preferably, the system consists of a heat pump HPB formed by a four-way valve 244B that allows the direction of flow of the refrigerant 242 to be switched, and the blower unit 21B is equipped with a first blower fan 251B that blows cold air TK1 or warm air TK2 that passes through the blower heat exchanger 211B to the upper air outlet 14Ba, and the exhaust unit 22B is equipped with a second blower fan 252B that blows exhaust hot air HN that passes through the exhaust heat exchanger 221B to the lower air outlet 14Bb. In this case, the air conditioning unit 2B can be made more comfortable and compact, and heating and cooling functions can be efficiently realized with less power consumption.

[0078] More specifically, a cross-flow fan should be used for the first blower fan 251B. A cross-flow fan has a structure in which airflow passes through a cylindrical runner, allowing for quiet and uniform airflow over a wide area. Therefore, it can create a more comfortable air conditioning environment for seated individuals TZ.

[0079] Furthermore, an axial fan is preferable for the second blower fan 252B. An axial fan has a structure in which the blades attached to the central axis rotate, drawing in airflow from the front of the blades and expelling it from the rear, thus enabling a small size while achieving high airflow. Therefore, the second blower fan 252B can be made more compact and housed in the storage compartment 12B, and power consumption can also be saved.

[0080] Furthermore, the blower heat exchanger 211B and the exhaust heat exchanger 221B are formed in a roughly cubic shape with multiple tubes through which the refrigerant 242 flows arranged horizontally, and gaps between the tubes through which air KK1 and KK2 pass. The vertical dimension (outer diameter of the cylinder) of the first blower fan 251B is smaller than the vertical dimension of the blower heat exchanger 211B, and the vertical dimension of the second blower fan 252B is smaller than the vertical dimension of the exhaust heat exchanger 221B. In addition, the first blower fan 251B is positioned downstream of the blower heat exchanger 211B (behind the chair), and the second blower fan 252B is positioned upstream of the exhaust heat exchanger 221B (in front of the chair).

[0081] In this case, the partition wall 27B separating the blower unit 21B and the exhaust unit 22B can be formed in a stepped shape, lower at the front of the chair 1B and higher at the rear of the chair 1B, relative to the partition plate (which also serves as a blower guide plate) 261B of the air conditioning unit 2B, which is horizontally arranged along the seat portion 11B of the chair 1B. This allows the blower unit 21B and the exhaust unit 22B to be arranged partially intersecting in the vertical direction, enabling the air conditioning unit 2B to be stored more compactly within the storage compartment 12B of the chair 1B. The front end of the partition wall 27B is connected to a vertical partition wall 262B that forms a flow path for the air KK2 drawn in from the front of the blades of the second blower fan 252B. Control equipment 2SB for controlling the operation of the air conditioning unit 2B is mounted on the partition wall 262B.

[0082] Furthermore, the air conditioning unit 2B consists of a heat pump HPB formed so that the direction of flow of the refrigerant 242 can be switched by a four-way valve 244B, and the blower unit 21B is equipped with a first blower fan 251B that blows cold air TK1 or warm air TK2 that passes through the blower heat exchanger 211B to the upper air outlet 14Ba. As shown in Figures 6 and 9, during cooling, the first blower fan 251B can send the cold air TK1, which has been cooled by the low-pressure, low-temperature refrigerant 242(P3) absorbing the heat of the air KK1 blown into the blower heat exchanger 211B through which the low-pressure, low-temperature refrigerant 242(P3) flows, to the upper side of the chair 1B from the upper air outlet 14Ba, thereby effectively lowering the temperature (room temperature) around the upper body of the seated person TZ. Furthermore, as shown in Figures 6 and 10, during heating when the direction of flow of the refrigerant 242 is switched by the four-way valve 244B, the first blower fan 251B can send out warm air TK2, which is heated by the high-pressure, high-temperature refrigerant 242 (Q1) heating the air KK1 blown into the blower heat exchanger 211B through which the high-pressure, high-temperature refrigerant 242 (Q1) flows, to the upper side of the chair 1B from the upper air outlet 14Ba, thereby effectively raising the temperature (room temperature) around the upper body of the seated person TZ.

[0083] Furthermore, the exhaust unit 22B is equipped with a second blower fan 252B that blows the exhaust hot air HN passing through the exhaust heat exchanger 221B to the lower air outlet 14Bb. As shown in Figures 6 and 9, during cooling, the second blower fan 252B releases the unwanted exhaust hot air HN, which has been heated by the high-pressure, high-temperature refrigerant 242(P1) heating the air KK2 blown into the exhaust heat exchanger 221B through which the high-pressure, high-temperature refrigerant 242(P1) flows, to the underside of the chair 1B through the lower air outlet 14Bb, thereby maintaining the temperature (room temperature) around the upper body of the seated person TZ at an appropriate level. Furthermore, as shown in Figures 6 and 10, during heating when the direction of flow of the refrigerant 242 is switched by the four-way valve 244B, the second blower fan 252B releases the excess exhaust hot air HN, which is cooled by the low-pressure, low-temperature refrigerant 242 (Q3) cooling the air KK2 blown into the exhaust heat exchanger 221B through which the low-pressure, low-temperature refrigerant 242 (Q3) flows, to the underside of the chair 1B through the lower air outlet 14Bb, thereby maintaining an appropriate temperature (room temperature) around the upper body of the seated person TZ. As a result, an even more comfortable working environment can be realized for the seated person TZ sitting in the chair 1B.

[0084] As shown in Figures 9 and 10, an accumulator 245B for gas-liquid separation is attached to the input terminal 231B of the compressor 23B, and a four-way valve 244B connected to the blower heat exchanger 211B, the exhaust heat exchanger 221B, and the accumulator 245B is attached to the output terminal 232B of the compressor 23B. During cooling, the output terminal 232B of the compressor 23B is connected to the exhaust heat exchanger 221B, and the accumulator 245B is connected to the blower heat exchanger 211B via the four-way valve 244B. During heating, the output terminal 232B of the compressor 23B is connected to the blower heat exchanger 211B, and the accumulator 245B is connected to the exhaust heat exchanger 221B via the four-way valve 244B.

[0085] Furthermore, the air conditioning unit 2B operates as follows during cooling and heating. Specifically, during cooling, as shown in Figures 6 and 9, the refrigerant 242, which has been converted into a high-pressure, high-temperature gaseous state P1 by the compressor 23B, is sent to the exhaust heat exchanger 221B. In the exhaust heat exchanger 221B, the blown air KK2 is heated by the high-pressure, high-temperature refrigerant 242 (P1). The unwanted exhaust hot air HN, which has been heated, is released by the second blower fan 252B through the lower air outlet 14Bb to the underside of the chair 1B. The refrigerant 242 that has passed through the exhaust heat exchanger 221B has lost some of its temperature to the exhaust hot air HN, and has become a high-pressure, medium-temperature liquid P2, which is sent to the expansion valve 243B.

[0086] Then, as the refrigerant 242 (P2) passes through the expansion valve 243B, it undergoes adiabatic expansion and is converted into a low-pressure, low-temperature gas-liquid mixture state P3, which is then sent to the blower heat exchanger 211B. In the blower heat exchanger 211B, the blown air KK1 is cooled by the low-pressure, low-temperature refrigerant 242 (P3). The cooled cold air TK1 is then sent out by the first blower fan 251B from the upper air outlet 14Ba to the upper side of the chair 1B, effectively lowering the room temperature on the upper body side of the seated person TZ. After passing through the blower heat exchanger 211B, the refrigerant 242 becomes a low-pressure, medium-temperature gaseous state P4 and returns to the compressor 23B via the accumulator 245B, but the liquid contained in the refrigerant 242 is separated in the accumulator 245B.

[0087] On the other hand, during heating, as shown in Figures 6 and 10, the refrigerant 242, which has been converted into a high-pressure, high-temperature gaseous state Q1 by the compressor 23B, is sent to the blower heat exchanger 211B. In the blower heat exchanger 211B, the blown air KK1 is heated by the high-pressure, high-temperature refrigerant 242 (Q1). The heated warm air TK2 is sent out by the first blower fan 251B from the upper air outlet 14Ba to the upper side of the chair 1B, effectively raising the room temperature on the upper body side of the seated person TZ. After passing through the blower heat exchanger 211B, the refrigerant 242 loses heat due to the heat absorbed by the warm air TK2, and becomes a high-pressure, medium-temperature liquid Q2, which is sent to the expansion valve 243B.

[0088] Then, as the refrigerant 242(Q2) passes through the expansion valve 243B, it undergoes adiabatic expansion and is converted into a low-pressure, low-temperature gas-liquid mixture Q3, which is then sent to the exhaust heat exchanger 221B. In the exhaust heat exchanger 221B, the blown air KK2 is cooled by the low-pressure, low-temperature refrigerant 242(Q3). The cooled and unnecessary exhaust hot air HN is released by the second blower fan 252B through the lower air outlet 14Bb to the underside of the chair 1B. This allows the room temperature on the upper side of the seated person TZ to be maintained. After passing through the exhaust heat exchanger 221B, the refrigerant 242 becomes a low-pressure, medium-temperature gaseous state Q4 and returns to the compressor 23B via the accumulator 245B, but the liquid contained in the refrigerant 242(Q4) is separated in the accumulator 245B.

[0089] Furthermore, as shown in Figures 9 and 10, a temperature sensor 246Ba for detecting room temperature is provided near the blower heat exchanger 211B. When this temperature sensor 246Ba detects that the room temperature has reached the set temperature, it stops the operation of the compressor 23B, and when it detects that the room temperature has fallen below the set temperature, it restarts the operation of the compressor 23B. This allows the room temperature to be maintained at a constant level. In addition, a temperature sensor 246Bb for preventing freezing is provided near the exhaust heat exchanger 221B. When this temperature sensor 246Bb detects frost on the exhaust heat exchanger 221B, it performs a defrosting operation.

[0090] Furthermore, in the air conditioning unit 10B with chair function, as shown in Figures 8 to 10, it is preferable to have a first drain pan 28Ba located below the blower heat exchanger 211B, a second drain pan 28Bb located below the exhaust heat exchanger 221B and connected downstream to the first drain pan 28Ba, and a drain pool 29B located downstream to the second drain pan 28Bb and having a heater device 291B, and positioned in the airflow path of the exhaust hot air HN. The condensed water accumulated in the first drain pan 28Ba is collected in the drain pool 29B via the second drain pan 28Bb, and the drain water collected in the drain pool 29B is evaporated by the heater device 291B.

[0091] In this case, the condensate water generated when the air conditioning unit 2B is in operation can be automatically vaporized and released to the outside 1BG along with the exhaust hot air HN. Therefore, there is no need to separately install a tank for storing condensate water or a drain pipe for condensate water, and the air conditioning unit 10B with chair function can be moved to any position, further enhancing convenience.

[0092] Furthermore, the condensed water accumulated in the first drain pan 28Ba is collected in the drain pool 29B via the second drain pan 28Bb, and the drain water collected in the drain pool 29B is evaporated by the heater device 291B. For example, during cooling, the condensed water that accumulates in the first drain pan 28Ba due to condensation on the blower heat exchanger 211B through which the low-pressure, low-temperature refrigerant 242 flows is heated by the exhaust heat exchanger 221B through which the high-pressure, high-temperature refrigerant 242(P1) flows as it passes through the second drain pan 28Bb, and is collected in the drain pool 29B as heated drain water. Therefore, the drain water collected in the drain pool 29B can be quickly boiled and evaporated by the heater device 291B. As a result, the drain water can be efficiently evaporated with less power consumption.

[0093] Here, the first drain pan 28Ba is positioned higher than the second drain pan 28Bb, and the second drain pan 28Bb is positioned higher than the drain pool 29B. The first drain pan 28Ba and the second drain pan 28Bb are connected by piping, and the second drain pan 28Bb and the drain pool 29B are connected by piping. The condensed water accumulated in the first drain pan 28Ba is collected in the second drain pan 28Bb until a certain amount has accumulated, and then collected in the drain pool 29B. The drain pool 29B is equipped with a lower water level sensor 292B for detecting the lower limit of the accumulated drain water and an upper water level sensor 293B for detecting the upper limit, and a heater device 291B is operated so that the drain water accumulated in the drain pool 29B is maintained between the lower limit and the upper limit.

[0094] Furthermore, a PCT (Positive Temperature Coefficient) heater is preferred for the heater device 291B. PCT heaters have the property that their resistance increases as the temperature rises, so the temperature stabilizes at a certain temperature. Therefore, they do not require external control and can control the appropriate temperature themselves, further saving power consumption.

[0095] Furthermore, in the air conditioning unit with chair function 10B, as shown in Figures 6 and 7, the front leg portion 16Ba of the chair 1B is preferably provided with a partition plate 161B that forms a heel relief portion KTN into which the heel KT of the seated person TZ can be inserted, and the partition plate 161B preferably has an air inlet 162B formed in which air KK1 passes through the heat exchanger 211B for ventilation. In this case, when a seated person TZ sitting on the chair 1B stands up, they can insert their heel KT into the heel relief portion KTN, thereby bending the bending angle of their knee HZ to 90 degrees or less and easily standing up. For example, even in a narrow room, a seated person TZ sitting on the air conditioning unit with chair function 10B can easily stand up, further enhancing the convenience of the air conditioning unit with chair function 10B.

[0096] Next, a booth of the first embodiment equipped with an air conditioning system with a chair function according to another embodiment will be described with reference to Figures 1 and 11. Figure 11 shows a schematic side view of the booth of the first embodiment equipped with the air conditioning system with a chair function shown in Figure 1.

[0097] As shown in Figures 1 and 11, the booth 50 of the first embodiment equipped with the chair-equipped air conditioning unit 10 has an indoor space SK where one or more seated persons TZ can work or reside while sitting on the chair-equipped air conditioning unit 10, and is formed to be partitioned by side wall panels 52 that surround the outer perimeter of the chair-equipped air conditioning unit 10 from at least three directions. In Figure 11, the booth 50 is partitioned by a floor plate 51 on which the chair-equipped air conditioning unit 10 is placed, side wall panels 52 that surround the outer perimeter of the chair-equipped air conditioning unit 10 from at least three directions (four directions in this case), a door 521 installed on one of the side wall panels 52, and a ceiling plate 53 that closes the top of the side wall panels 52, forming a single private room or hut, but is not limited to this. For example, the booth may consist of an interior space SK without a floorboard 51, door 521, or ceilingboard 53, and partitioned only by side wall panels 52 (so-called partitions) that surround the outer perimeter of the air conditioning unit with chair function 10 from three directions. Also, although Figure 11 shows an example of a booth 50 consisting of a private room for one person, it goes without saying that booths for two people, four people, or other groups of people are also acceptable.

[0098] Furthermore, this booth 50 is designed to be installed on the floor FL in an office, and is also designed to accommodate necessary information equipment. Therefore, it can be used for small meetings, teleworking, etc. In addition, the floor panel 51, side wall panels 52, door 521, ceiling panel 53, etc. that make up this booth 50 can be easily disassembled and assembled in the office, and its installation location can be easily moved. Note that this booth 50 may be installed outdoors as well as indoors.

[0099] As described above, the booth 50 has a space SK where one or more seated persons TZ can work or live while sitting in the chair-equipped air conditioning unit 10, and is formed to be partitioned by side wall panels 52 that surround the outer perimeter of the chair-equipped air conditioning unit 10 from at least three directions. Therefore, the air conditioning inside the booth 50 can be kept at a comfortable level with only the air conditioning unit 2 of the chair-equipped air conditioning unit 10 where the seated persons TZ sit. As a result, there is no need to install a new air conditioning unit for each booth 50, and the high cost of air conditioning can be avoided.

[0100] Furthermore, since the booth 50 is formed so that it can be partitioned by side wall panels 52 that surround the outer perimeter of the air conditioning unit 10 with chair function from at least three directions, it is possible to suppress the escape of conditioned air TK from the booth 50 and further reduce the power consumption of the air conditioning unit 2. As a result, it is possible to provide a low-cost and comfortable booth 50 equipped with an air conditioning unit 10 with chair function.

[0101] Furthermore, if the booth 50 is partitioned by a floor plate 51 on which the air conditioning unit 10 with chair function is placed, a side wall plate 52 with a door 521, and a ceiling plate 53, as shown in Figure 11, then the intrusion of heat from outside the booth 50 and the diffusion of heat to outside the booth 50 can be more reliably reduced or prevented. As a result, the power consumption of the air conditioning unit 2 can be further reduced.

[0102] Furthermore, it is preferable that the booth 50 is equipped with a floor plate 51 on which an air conditioning unit 10 with a chair function is placed at a position spaced apart from the floor surface FL, and that the floor plate 51 has an openable and closable ventilation window 511 located adjacent to the lower end 18 of the chair 1. In this case, while maintaining a comfortable air conditioning level inside the booth 50, the old conditioned air (warm air TK2) can be released outside the booth 50 through the ventilation window 511 and replaced with fresh air TK3. Therefore, it is possible to provide a comfortable booth 50 at low cost while suppressing an increase in the power consumption of the air conditioning unit 2.

[0103] For example, as shown in Figures 1 and 11, when the chair-equipped air conditioning unit 10 is operated for cooling, conditioned air TK (cold air TK1) is circulated into the space SK inside the booth from the upper air outlet 14a formed at the upper end 151 of the backrest 15, and the ventilation window 511 is opened, allowing the second blower fan 252 to send conditioned air (warm air TK2) heated by the warm air unit 22 out of the booth through the ventilation window 511 from the lower air outlet 14b, thereby suppressing the temperature rise around the feet of the seated person TZ. Conversely, when the chair-equipped air conditioning unit 10 is operated for heating, the ventilation window 511 is closed, allowing the second blower fan 252 to send conditioned air (warm air TK2) heated by the warm air unit 22 into the booth through the floor plate 51 from the lower air outlet 14b, thereby promoting the temperature rise around the feet of the seated person TZ.

[0104] Next, a booth of a second embodiment, equipped with an air conditioning system with a chair function according to another embodiment, will be described using Figures 6 and 12 to 16. Figure 12 shows a schematic perspective view of the booth of the second embodiment equipped with the air conditioning system with a chair function shown in Figure 6. Figure 13 shows a cross-sectional view of CC shown in Figure 12. Figure 14 shows an enlarged side view of section D shown in Figure 13. Figure 15 shows a bottom perspective view of section D shown in Figure 13. Figure 16 shows a bottom perspective view of section D shown in Figure 15, with a humidity control sheet material placed on the floor surface.

[0105] As shown in Figures 6 and 12-16, the booth 50B of the second embodiment, equipped with the chair-equipped air conditioning unit 10B, has an indoor space SK where one or more seated persons TZ can work or reside while seated in the chair-equipped air conditioning unit 10B, and is formed so that the perimeter of the chair-equipped air conditioning unit 10B can be partitioned by side wall panels 52B that surround it from at least three directions. Therefore, as in the first embodiment, the air conditioning inside the booth 50B can be kept at a comfortable level with only the air conditioning unit 2B of the chair-equipped air conditioning unit 10B where the seated persons TZ sit. As a result, there is no need to install a new air conditioning unit for each booth 50B, and the high cost of air conditioning can be avoided. Furthermore, since the booth 50B is formed so that the chair-equipped air conditioning unit 10B can be partitioned by side wall panels 52B that surround it on at least three sides, the conditioned air TK can be prevented from escaping outside the booth 50B by the side wall panels 52B, and the power consumption of the air conditioning unit 2B can be further reduced. Therefore, it is possible to provide a low-cost, comfortable booth 50B equipped with an air conditioning unit 10B that also functions as a chair.

[0106] Furthermore, in the booth 50B of the second embodiment equipped with the chair-equipped air conditioning unit 10B, as shown in Figures 12 and 13, the side wall panels 52B are formed to surround the outer periphery of the chair-equipped air conditioning unit 10B from four directions, the booth 50B is provided with a ceiling panel 53B connected to the upper ends of each side wall panel 52B, and the upper air outlet 14Ba is preferably formed to blow cool air TK1 or warm air TK2 diagonally upward and rearward from the upper end 151B of the backrest portion 15B of the chair 1B.

[0107] In this case, the cool air TK1 or warm air TK2 blown from the upper air outlet 14Ba can be directed upward along the side wall panel 52B of the booth 50B towards the ceiling panel 53B, and diffused into the indoor space SK via the ceiling panel 53B. Therefore, even in the narrow booth 50B, the discomfort of the cool air TK1 or warm air TK2 blown from the upper air outlet 14Ba directly touching the seated person TZ can be avoided, and the air conditioning inside the booth 50 can be kept more uniform and comfortable.

[0108] Here, as shown in Figures 12 to 14, the air conditioning unit with chair function 10B is installed on the floorboard 51B with the backrest 15B of the chair 1B in approximate contact with the left side wall panel 52Ba of the booth 50B. The legs 16B of the chair 1B do not have casters 17B, and the lower ends 18B of the legs 16B are in direct contact with the floorboard 51B. On the right side wall panel 52Bb, opposite the left side wall panel 52Ba to which the backrest 15B of the chair 1B is in approximate contact, a tabletop 561B is mounted horizontally above the seating area 11B of the chair 1B, and a monitor screen 562B is mounted above the tabletop 561B. A door 521B is mounted on the front side wall panel 52B of the booth 50B. Additionally, a sprinkler 532B and a ventilation fan 533 are installed on the ceiling panel 53B.

[0109] Furthermore, an arc-shaped guide wall 531B is installed at the corner where the ceiling panel 53B and the right side wall panel 52Bb intersect. In this case, the conditioned air TK (cold air TK1 or warm air TK2) blown from the upper air outlet 14Ba formed at the upper end 151B of the backrest 15B of the chair 1B rises along the left side wall panel 52Ba to the ceiling panel 53B, then descends from the ceiling panel 53B along the guide wall 531B and the right side wall panel 52Bb, contacts the table panel 561B, and then flows into the room. As a result, the conditioned air TK (cold air TK1 or warm air TK2) can be diffused into the room space SK while avoiding direct contact with the seated person TZ. The arc-shaped guide wall 531B may be installed as needed.

[0110] Furthermore, in the booth 50B of the second embodiment equipped with the chair-equipped air conditioning unit 10B, as shown in Figures 13 and 14, the booth 50B is provided with a floor plate 51B on which the chair-equipped air conditioning unit 10B is placed at a position spaced apart from the floor surface FL. The floor plate 51B preferably has an introduction window 511B adjacent to the lower end 18B of the chair 1B for introducing air KK2 passing through the exhaust heat exchanger 221B from the floor surface FL side, and an exhaust window 512B for discharging exhaust hot air HN that has passed through the exhaust heat exchanger 221B to the floor surface FL side. Adjustment screws 514B are attached to the corners of the floor plate 51B to adjust the gap with the floor surface FL.

[0111] In this case, air KK2 from outside the booth 50B is introduced through the introduction window 511B of the floor plate 51B, and the exhaust hot air HN that has passed through the exhaust heat exchanger 221B can be released outside the booth 50B through the exhaust window 512B. Therefore, by separating the conditioned air TK inside the booth 50 from the unnecessary exhaust hot air HN, the power consumption of the air conditioning unit 2B can be reduced, and the air conditioning inside the booth 50B can be kept in a comfortable state. As a result, a comfortable booth 50B can be provided at a low cost while suppressing an increase in the power consumption of the air conditioning unit 2B. A filter device 513B for the air KK2 introduced into the introduction window 511B is detachably mounted on the underside of the floor plate 51B. The filter device 513B extends in the front-rear direction of the booth 50B and is designed to be pulled out to the front of the booth 50B (door 521B side) for filter replacement.

[0112] Furthermore, in the booth 50B of the second embodiment equipped with the chair-equipped air conditioning unit 10B, as shown in Figures 14 and 15, the lower surface of the floor plate 51B is provided with an air partition plate 541B that restricts the flow path of air KK2 introduced into the introduction window 511B, and an exhaust partition plate 542B that restricts the flow path of exhaust hot air HN discharged from the exhaust window 512B, and it is preferable that the opening 541Ba of the air partition plate 541B and the opening 5423a of the exhaust partition plate 542B are formed facing opposite directions.

[0113] In this case, the air KK2 introduced into the inlet window 511B and the exhaust hot air HN discharged from the exhaust window 512B can be prevented from mixing below the floor plate 51B. As a result, the heat exchange efficiency in the exhaust heat exchanger 221B can be improved, and the air conditioning inside the booth 50B can be kept at a comfortable level with less power consumption.

[0114] Here, the air partition plate 541B and the exhaust partition plate 542B are formed in a roughly S-shape when viewed from below. The opening 541Ba of the air partition plate 541B is formed near the front side wall plate 52B of the booth 50B, and the opening 542Ba of the exhaust partition plate 542B is formed near the rear side wall plate 52B of the booth 50B. The air partition plate 541B and the exhaust partition plate 542B are formed at approximately the same height as the gap between the floor plate 51B and the floor surface FL. The small gaps that occur between the air partition plate 541B and the exhaust partition plate 542B and the floor surface FL should be sealed with sealing tape 543B or the like.

[0115] Furthermore, in the booth 50B of the second embodiment equipped with the chair-equipped air conditioning unit 10B, as shown in Figures 14 and 16, it is preferable that a humidity control sheet material 55B, which is larger than the exhaust window 512B, is placed on the floor surface FL facing the exhaust window 512B.

[0116] In this case, the humidity control sheet material 55B absorbs the moisture contained in the exhaust air HN and releases it to the outside, thereby preventing condensation on the floor surface FL. In other words, in this booth 50B, when the drain water accumulated in the drain pool 29B of the air conditioning unit with chair function 10B is evaporated by the heater device 291B, the water vapor is discharged from the exhaust window 512B along with the exhaust air HN, potentially causing condensation on the floor surface FL. However, since the humidity control sheet material 55B, which is larger than the exhaust window 512B, is placed on the floor surface FL opposite the exhaust window 512B, the humidity control sheet material 55B absorbs the moisture contained in the exhaust air HN and releases it into the outside air from a point away from the exhaust window 512B, thereby preventing condensation on the floor surface FL.

[0117] Here, the humidity control sheet material 55B is placed on the floor surface FL facing the inlet window 511B and the exhaust window 512B. Therefore, moisture absorbed by the humidity control sheet material 55B on the exhaust window 512B side can be released into the outside air via the humidity control sheet material 55B on the inlet window 511B side. As a result, even when the air conditioning unit 2B of the air conditioning system with chair function 10B is operated for a long time, the humidity control sheet material 55B can not be saturated with moisture. For example, the humidity control sheet material 55B can be made of a plate-like material with fine voids, which is a mixture of calcium silicate with natural minerals such as vermiculite and diatomaceous earth.

[0118] Figure 12 illustrates a booth 50B consisting of a private room for one or a small number of people, but it is of course possible to use a booth for multiple people. Furthermore, this booth 50B is designed to be installed on the floor FL in an office and is also designed to accommodate necessary information equipment. Therefore, it can be used for small meetings or teleworking. In addition, the floor panel 51B, side wall panels 52B, door 521B, ceiling panel 53B, etc. that make up this booth 50B can be easily disassembled or assembled in the office, and its installation location can be easily moved without altering the office. Moreover, this booth 50B may be installed outdoors as well as indoors.

[0119] Next, a third embodiment of a booth equipped with an air conditioning system with a chair function, according to another embodiment, will be described using Figures 1, 6, and 17. Figure 17 shows a schematic configuration view of the third embodiment of a booth equipped with an air conditioning system with a chair function, as shown in Figure 1 or Figure 6.

[0120] As shown in Figures 1, 6, and 17, the booth 60 of the third embodiment, equipped with the chair-equipped air conditioning units 10 and 10B, has an indoor space SK where one or more seated persons can work or reside while sitting in the chair-equipped air conditioning units 10 and 10B, and is partitioned by a floor member 61 on which the chair-equipped air conditioning units 10 and 10B are placed, a frame member 62 extending upward from the outer edge of the floor member 61, and a sheet member 63 covering the frame member 62.

[0121] Here, chairs 1 and 1B may be benches or beds (bedding). Floor member 61 may be a floor mat made of an elastic material or a floor board made of a rigid material. The frame member 62 is composed of multiple frame members connected in a dome shape, but it is not necessarily limited to being connected in a dome shape; it is acceptable as long as it can secure an indoor space SK of a predetermined size. The sheet member 63 covers the frame member 62 from above, and its shape is not particularly restricted, but it is sufficient if it can form an entrance in part of it. This booth 60 may be installed outdoors like an outdoor tent, but it may also be installed indoors (in an office).

[0122] As described above, the booth 60 has a space SK where one or more seated persons can work or reside while sitting in the chair-equipped air conditioning units 10 and 10B. Since it is formed to be partitioned by a floor member 61 on which the chair-equipped air conditioning units 10 and 10B are placed, a frame member 62 extending upward from the outer edge of the floor member 61, and a sheet member 63 covering the frame member 62, the air conditioning inside the booth 60 can be kept at a comfortable temperature using only the air conditioning units 2 and 2B of the chair-equipped air conditioning units 10 and 10B on which the seated persons sit. Therefore, there is no need to install a new air conditioning unit for each booth 60, and the high cost of air conditioning can be avoided.

[0123] Furthermore, since the booth 60 is formed to be partitioned by a floor member 61 on which the air conditioning units 10 and 10B with chair functions are placed, a frame member 62 extending upward from the floor member 61, and a sheet member 63 covering the frame member 62, the booth 60 can be made lighter, easily transported, and installed not only indoors but also outdoors. In addition, the sheet member 63 covering the frame member 62 can easily prevent the conditioned air TK from escaping outside the booth 60, and the power consumption of the air conditioning units 2 and 2B can be reduced at a lower cost. As a result, a low-cost and comfortable booth 60 equipped with air conditioning units 10 and 10B with chair functions can be provided.

[0124] <Effects and Effects> As described in detail above, according to the chair-equipped air conditioning system 10, 10B of this embodiment, the air conditioning units 2, 2B are housed inside chairs 1, 1B (1N, 1BN) and are configured to blow conditioned air TK outwards (1G, 1BG) from chairs 1, 1B. Therefore, the air conditioning units 2, 2B can move freely around the room together with chairs 1, 1B. This makes it possible to create a comfortable working environment in various types of offices, such as free-address offices, co-working offices, and shared offices, without installing new air conditioning equipment. Furthermore, the air conditioning units 2, 2B only need to be small enough to air condition the area around the seated person TZ sitting in chairs 1, 1B, thus avoiding the high cost of air conditioning equipment. Moreover, only the air conditioning units 2, 2B of the chair 1, 1B where the seated person TZ is sitting can be operated as needed by the seated person TZ, enabling a comfortable working environment for each seated person TZ with low power consumption.

[0125] Therefore, according to this embodiment, it is possible to avoid high costs for air conditioning equipment and provide air conditioning units 10 and 10B with chair functions that can realize a comfortable working environment for each seated person TZ with low power consumption.

[0126] Furthermore, according to this embodiment, the air conditioning units 2 and 2B are housed in storage compartments 12 and 12B formed in the empty space below the seating portions 11 and 11B of the chairs 1 and 1B, and air outlets 14 and 14B that communicate with the air conditioning units 2 and 2B are formed in the outer periphery portions 13 and 13B of the chairs 1 and 1B. This allows for compact housing of the air conditioning units 2 and 2B by utilizing the empty space of the chairs 1 and 1B while ensuring design freedom for the chairs 1 and 1B. In addition, although the weight of the chairs 1 and 1B increases due to the air conditioning units 2 and 2B, by housing them in storage compartments 12 and 12B formed in the empty space below the seating portions 11 and 11B of the chairs 1 and 1B, the center of gravity of the chairs 1 and 1B can be positioned lower, allowing the chairs 1 and 1B to be placed in the required position in a balanced manner or moved easily. Furthermore, since air outlets 14 and 14B are formed on the outer perimeters 13 and 13B of chairs 1 and 1B and are connected to air conditioning units 2 and 2B, comfortable conditioned air TK can be supplied to the occupants TZ sitting in chairs 1 and 1B simply by forming the air outlets 14 and 14B at appropriate positions on the outer perimeters 13 and 13B of chairs 1 and 1B.

[0127] Furthermore, according to this embodiment, the air conditioning unit 2 is equipped with a cooling unit 21 that blows out cool air TK1 and a warming unit 22 that blows out warm air TK2, separated by a partition wall 27. The cooling unit 21 is located above the partition wall 27 and communicates with an upper air outlet 14a formed on the upper outer periphery 13a of the chair 1, and the warming unit 22 is located below the partition wall 27 and communicates with a lower air outlet 14b formed on the lower outer periphery 13b of the chair 1. As a result, cool air TK1 can be efficiently blown from the cooling unit 21 to the upper side of the chair 1 where warm air tends to accumulate, and warm air TK2 can be efficiently blown from the warming unit 22 to the lower side of the chair 1 where cool air tends to accumulate. Therefore, an even more comfortable working environment can be realized for the occupant TZ sitting in the chair 1.

[0128] Furthermore, according to this embodiment, the air conditioning unit 2 has a compressor 23, a condenser 221, an expansion valve 243, an evaporator 211, and piping 241 connecting these in order, and consists of a heat pump HP that circulates refrigerant 242 in the piping 241. As a result, the air conditioning unit 2 can be made compact, and heating and cooling functions can be efficiently realized with low power consumption.

[0129] Furthermore, the cooling unit 21 is equipped with a first blower fan 251 that blows conditioned air TK passing through the evaporator 211 to the upper air outlet 14a. As a result, the conditioned air TK (cold air TK1), which has been cooled by the refrigerant 242 cooled by the expansion valve 243 absorbing heat from the air passing through the evaporator 211, can be sent by the first blower fan 251 from the upper air outlet 14a to the upper outer circumference 13a of the chair 1, thereby effectively lowering the temperature around the head of the seated person TZ.

[0130] Furthermore, the warming unit 22 is equipped with a second blower fan 252 that blows conditioned air TK passing through the condenser 221 to the lower air outlet 14b. As a result, the refrigerant 242 heated by the compressor 23 releases heat into the air passing through the condenser 221, and the heated conditioned air (warm air TK2) is then blown by the second blower fan 252 from the lower air outlet 14b to the lower outer circumference 13b of the chair 1, effectively raising the temperature around the feet of the seated person TZ. Therefore, a more comfortable working environment can be achieved for the seated person TZ sitting in the chair 1.

[0131] Furthermore, according to this embodiment, the air conditioning unit 2B comprises a blower unit 21B that blows cold air TK1 or warm air TK2 and an exhaust unit 22B that blows exhaust hot air HN, separated by a partition wall 27B. The blower unit 21B is located above the partition wall 27B and communicates with an upper air outlet 14Ba formed on the upper outer periphery 13Ba of the chair 1B, and the exhaust unit 22B is located below the partition wall 27B and communicates with a lower air outlet 14Bb formed on the lower outer periphery 13Bb of the chair 1B. As a result, conditioned air TK of cold air TK1 or warm air TK2 can be efficiently blown from the blower unit 21B to the upper body of the seated person TZ sitting on the upper side of the chair 1B, and unwanted exhaust hot air HN can be released from the exhaust unit 22B at the feet of the seated person TZ. Therefore, a more comfortable working environment can be created for the occupant TZ sitting in chair 1B.

[0132] Furthermore, according to this embodiment, the air conditioning unit 2B consists of a compressor 23B, a blower heat exchanger 211B, an expansion valve 243B, an exhaust heat exchanger 221B, a four-way valve 244B, piping 241B connecting these, and a refrigerant 242 flowing through the piping 241B, and is configured to allow switching of the flow direction of the refrigerant 242 by the four-way valve 244B. The blower unit 21B is equipped with a first blower fan 251B that blows cold air TK1 or warm air TK2 passing through the blower heat exchanger 211B to the upper air outlet 14Ba, and the exhaust unit 22B is equipped with a second blower fan 252B that blows exhaust hot air HN passing through the exhaust heat exchanger 221B to the lower air outlet 14Bb. As a result, the air conditioning unit 2B can be made compact, and heating and cooling functions can be efficiently realized with low power consumption.

[0133] Furthermore, the air conditioning unit 2B consists of a heat pump HPB formed so that the direction of flow of the refrigerant 242 can be switched by a four-way valve 244B, and the blower unit 21B is equipped with a first blower fan 251B that blows cold air TK1 or warm air TK2 that passes through the blower heat exchanger 211B to the upper air outlet 14Ba. In cooling mode, the first blower fan 251B can send the cold air TK1, which has been cooled by the low-pressure, low-temperature refrigerant 242(P3) absorbing the heat of the air KK1 blown into the blower heat exchanger 211B through which the low-pressure, low-temperature refrigerant 242(P3) flows, to the upper side of the chair 1B from the upper air outlet 14Ba, thereby effectively lowering the temperature (room temperature) around the upper body of the seated person TZ. Furthermore, during heating, when the direction of flow of the refrigerant 242 is switched by the four-way valve 244B, the warm air TK2, heated by the high-pressure, high-temperature refrigerant 242 (Q1) that blows air KK1 into the blower heat exchanger 211B through which the high-pressure, high-temperature refrigerant 242 (Q1) flows, can be sent out by the first blower fan 251B from the upper air outlet 14Ba to the upper side of the chair 1B, thereby effectively raising the temperature (room temperature) around the upper body of the seated person TZ.

[0134] Furthermore, the exhaust unit 22B is equipped with a second blower fan 252B that blows the exhaust hot air HN passing through the exhaust heat exchanger 221B to the lower air outlet 14Bb. In cooling mode, the second blower fan 252B releases the unwanted exhaust hot air HN, which has been heated by the high-pressure, high-temperature refrigerant 242(P1) heating the air KK2 blown into the exhaust heat exchanger 221B through which the high-pressure, high-temperature refrigerant 242(P1) flows, to the underside of the chair 1B through the lower air outlet 14Bb, thereby maintaining the temperature (room temperature) around the upper body of the seated person TZ at an appropriate level. Furthermore, during heating, when the direction of flow of the refrigerant 242 is switched by the four-way valve 244B, the air KK2 blown into the exhaust heat exchanger 221B through which the low-pressure, low-temperature refrigerant 242 (Q3) flows is cooled by the low-pressure, low-temperature refrigerant 242 (Q3). The second blower fan 252B then releases the excess exhaust hot air HN, cooled by the air KK2, through the lower air outlet 14Bb to the underside of the chair 1B, thereby maintaining an appropriate temperature (room temperature) around the upper body of the seated person TZ. As a result, an even more comfortable working environment can be achieved for the seated person TZ sitting in the chair 1B.

[0135] Furthermore, according to this embodiment, the system includes a first drain pan 28Ba located below the blower heat exchanger 211B, a second drain pan 28Bb located below the exhaust heat exchanger 221B and connected downstream to the first drain pan 28Ba, and a drain pool 29B located downstream to the second drain pan 28Bb and equipped with a heater device 291B, and positioned in the airflow path of the exhaust hot air HN. Condensed water accumulated in the first drain pan 28Ba is collected in the drain pool 29B via the second drain pan 28Bb, and the drain water collected in the drain pool 29B is evaporated by the heater device 291B. Therefore, the drain water generated when the air conditioning unit 2B is operated can be automatically vaporized and released to the outside along with the exhaust hot air HN. As a result, there is no need to install a tank for storing drain water or a drain water discharge pipe, and the air conditioning unit 10B with chair function can be moved to any position, further enhancing convenience.

[0136] Furthermore, the condensed water accumulated in the first drain pan 28Ba is collected in the drain pool 29B via the second drain pan 28Bb, and the drain water collected in the drain pool 29B is evaporated by the heater device 291B. For example, during cooling, the condensed water that condenses on the blower heat exchanger 211B and accumulates in the first drain pan 28Ba is heated by the exhaust heat exchanger 221B through which the high-pressure, high-temperature refrigerant 242(P1) flows as it passes through the second drain pan 28Bb, and is collected in the drain pool 29B as heated drain water. Therefore, the drain water collected in the drain pool 29B can be quickly boiled and evaporated by the heater device 291B. As a result, the drain water can be efficiently evaporated with low power consumption.

[0137] Furthermore, according to this embodiment, the front leg portion 16Ba of the chair 1B is provided with a partition plate 161B that forms a heel relief portion KTN into which the heel KT of the seated person TZ can be inserted. The partition plate 161B has an air inlet 162B for air KK1 that passes through the heat exchanger 211B for ventilation. As a result, when a seated person TZ sitting on the chair 1B stands up, they can insert their heel KT into the heel relief portion KTN, thereby bending their knees HZ to a bending angle of 90 degrees or less and easily standing up. For example, even in a small room, a seated person TZ sitting on this air conditioning unit with chair function 10B can easily stand up, further enhancing convenience.

[0138] Furthermore, according to the booth 50 equipped with an air conditioning unit with a chair function according to this other embodiment, the booth 50 has an indoor space SK where one or more seated persons TZ can work or reside while sitting in the air conditioning unit with a chair function 10, and is formed so that it can be partitioned by side wall panels 52 that surround the outer perimeter of the air conditioning unit with a chair function 10 from at least three directions. Therefore, the air conditioning inside the booth 50 can be kept at a comfortable level with only the air conditioning unit 2 of the air conditioning unit with a chair function 10 where the seated persons TZ sit. As a result, there is no need to install a new air conditioning unit for each booth 50, and the high cost of air conditioning units can be avoided. In addition, since the booth 50 is formed so that it can be partitioned by side wall panels 52 that surround the air conditioning unit with a chair function 10 on at least three sides, the side wall panels 52 can prevent conditioned air TK from escaping outside the booth 50, and the power consumption of the air conditioning unit 2 can be further reduced. As a result, a low-cost and comfortable booth 50 equipped with an air conditioning unit with a chair function 10 can be provided.

[0139] Furthermore, according to the booth 50 of this other embodiment, the booth 50 is equipped with a floor plate 51 on which an air conditioning unit 10 with a chair function is placed at a position spaced apart from the floor surface FL, and the floor plate 51 has an openable and closable ventilation window 511 at a position adjacent to the lower end 18 of the chair 1. As a result, while maintaining a comfortable air conditioning condition inside the booth 50, old conditioned air (warm air TK2) can be released outside the booth through the ventilation window 511 and replaced with fresh air TK3. Therefore, a comfortable booth 50 can be provided at low cost while suppressing an increase in the power consumption of the air conditioning unit 2.

[0140] Furthermore, according to the booth 50B of this other embodiment, the booth 50B has an indoor space SK where one or more seated persons TZ can work or reside while sitting in the chair-equipped air conditioning unit 10B, and is formed so that it can be partitioned by side wall panels 52B that surround the outer perimeter of the chair-equipped air conditioning unit 10B from at least three directions. Therefore, the air conditioning inside the booth 50B can be kept at a comfortable level with only the air conditioning unit 2B of the chair-equipped air conditioning unit 10B where the seated persons TZ sit. As a result, there is no need to install a new air conditioning unit for each booth 50B, and the high cost of air conditioning can be avoided. In addition, since the booth 50B is formed so that it can be partitioned by side wall panels 52B that surround the chair-equipped air conditioning unit 10B on at least three sides, the side wall panels 52B can suppress the escape of conditioned air TK outside the booth 50B, and the power consumption of the air conditioning unit 2B can be further reduced. As a result, a low-cost and comfortable booth 50B equipped with a chair-equipped air conditioning unit 10B can be provided.

[0141] Furthermore, according to the booth 50B of this other embodiment, the side wall panels 52B are formed to surround the outer periphery of the air conditioning unit with chair function 10B from four directions, the booth 50B is equipped with a ceiling panel 53B connected to the upper ends of each side wall panel 52B, and the upper air outlet 14Ba is formed to blow cool air TK1 or warm air TK2 diagonally upward and backward from the upper end 151B of the backrest portion 15B of the chair 1B. As a result, the cool air TK1 or warm air TK2 blown from the upper air outlet 14Ba can be raised along the side wall panels 52B of the booth 50B towards the ceiling panel 53B and diffused into the indoor space SK via the ceiling panel 53B. Therefore, even in the narrow booth 50B, the discomfort of the cool air TK1 or warm air TK2 blown from the upper air outlet 14Ba directly touching the seated person TZ can be avoided, and the air conditioning inside the booth 50 can be kept more uniform and comfortable.

[0142] Furthermore, according to the booth 50B of this other embodiment, the booth 50B is equipped with a floor plate 51B on which an air conditioning unit with chair function 10B is placed at a position spaced apart from the floor surface FL. The floor plate 51B has an introduction window 511B for introducing air KK2 that has passed through the exhaust heat exchanger 221B from the floor surface FL side, and an exhaust window 512B for discharging exhaust hot air HN that has passed through the exhaust heat exchanger 221B to the floor surface FL side. As a result, air KK2 from outside the booth 50B can be introduced from the introduction window 511B of the floor plate 51B, and the exhaust hot air HN that has passed through the exhaust heat exchanger 221B can be released to the outside of the booth 50B from the exhaust window 512B. Therefore, by separating the conditioned air TK inside the booth 50 from the unnecessary exhaust hot air HN, the power consumption of the air conditioning unit 2B can be reduced, and the air conditioning inside the booth 50B can be kept in a comfortable state. Therefore, it is possible to provide a comfortable booth 50B at a low cost while suppressing the increase in power consumption of the air conditioning unit 2B.

[0143] Furthermore, according to the booth 50B of this other embodiment, the lower surface of the floor plate 51B is provided with an air partition plate 541B that restricts the flow path of air KK2 introduced into the introduction window 511B, and an exhaust partition plate 542B that restricts the flow path of exhaust hot air HN discharged from the exhaust window 512B. The openings 541Ba of the air partition plate 541B and the openings 542Ba of the exhaust partition plate 542B are formed facing opposite directions, so that the air KK2 introduced into the introduction window 511B and the exhaust hot air HN discharged from the exhaust window 512B do not mix below the floor plate 51B. As a result, the heat exchange efficiency in the exhaust heat exchanger 221B can be improved, and the air conditioning inside the booth 50B can be kept in a comfortable state with less power consumption.

[0144] Furthermore, according to the booth 50B of this other embodiment, a humidity control sheet material 55B, which is larger than the exhaust window 512B, is placed on the floor surface FL facing the exhaust window 512B. As a result, the humidity control sheet material 55B absorbs the moisture contained in the exhaust hot air HN and releases it to the outside, thereby preventing condensation on the floor surface FL. In other words, in this booth 50B, when the drain water accumulated in the drain pool 29B of the air conditioning unit with chair function 10B is evaporated by the heater device 291B, the water vapor is discharged from the exhaust window 512B along with the exhaust hot air HN, potentially causing condensation on the floor surface FL. However, since a humidity control sheet material 55B, which is larger than the exhaust window 512B, is placed on the floor surface FL facing the exhaust window 512B, the humidity control sheet material 55B absorbs the moisture contained in the exhaust hot air HN and releases it to the outside air from a point away from the exhaust window 512B, thereby preventing condensation on the floor surface FL.

[0145] Furthermore, according to another embodiment of the booth 60 equipped with chair-equipped air conditioning units 10, 10B, the booth 60 has an indoor space SK where one or more seated persons TZ can work or reside while sitting on the chair-equipped air conditioning units 10, 10B. The booth 60 is partitioned by a floor member 61 on which the chair-equipped air conditioning units 10, 10B are placed, a frame member 62 extending upward from the outer edge of the floor member 61, and a sheet member 63 covering the frame member 62. Therefore, the air conditioning inside the booth 60 can be kept at a comfortable level using only the air conditioning units 2, 2B of the chair-equipped air conditioning units 10, 10B on which the seated persons TZ sit. As a result, there is no need to install a new air conditioning unit for each booth 60, and the high cost of air conditioning units can be avoided.

[0146] Furthermore, since the booth 60 is formed to be partitioned by a floor member 61 on which the air conditioning units 10 and 10B with chair functions are placed, a frame member 62 extending upward from the outer edge of the floor member 61, and a sheet member 63 covering the frame member 62, the booth 60 can be made lighter, easily transported, and installed not only indoors but also outdoors. In addition, the sheet member 63 covering the frame member 62 can easily prevent the conditioned air TK from escaping outside the booth 60, and the power consumption of the air conditioning units 2 and 2B can be reduced at a lower cost. As a result, a low-cost and comfortable booth 60 equipped with air conditioning units 10 and 10B with chair functions can be provided. [Industrial applicability]

[0147] The present invention can be used as a low-cost, comfortable booth equipped with a chair function, which can avoid the high cost of air conditioning equipment and realize a comfortable working environment for each seated person with low power consumption. [Explanation of Symbols]
