Description

  The present invention relates to an air conditioning system that imparts a heating or cooling effect with temperature-adjusted air to a region where a person exists in a space to be air conditioned.

  When air conditioning in an indoor space is desired, the indoor space is large, and generally a conditioned air blow-out device provided on the ceiling and an area where people near the floor that actually need air conditioning (so-called residential areas) )), The air conditioning cost will be enormous if the entire indoor space is subject to air conditioning so that the air conditioning effect can be applied to the living area. Conventionally, local air conditioning has been carried out by focusing on places where air conditioning is necessary.

  As an example of such local air conditioning, a nozzle-type air outlet device that can extend the reach distance of the conditioned air that has been blown out is arranged on the ceiling or a wall near the ceiling, and the conditioned air is moved to a distant residential area. The technique of performing air conditioning by sending it in has been widely used. An example of a conventional nozzle-type outlet device used for this is disclosed in registered utility model No. 3045940.

  However, in the method using such a nozzle-type air outlet device, the air flow of the conditioned air that has been blown out contacts and mixes with the room air around the air flow immediately after the blowout and diffuses into the room space. Since the air flow itself becomes weaker as it moves away from the air outlet device, the amount of air blown from the air outlet device is required as the target position of the conditioned air is farther from the air outlet device. For this reason, when the air outlet device and the living area are far apart, such as in a high ceiling space, the air outlet device and the entire system for supplying conditioned air to this are increased in size to accommodate large air volumes, There was a problem that the cost would increase due to the increase in scale.

  As another example of local air conditioning to avoid such problems, a floor outlet device is provided on the floor facing the living area, and conditioned air is blown from the vicinity of the person so that the air is conditioned to the immediate area of the person. The method of executing is also conventionally used. An example of a conventional floor outlet device used in this case is disclosed in Japanese Patent Application Laid-Open No. 7-324801.

Registered Utility Model No. 3045940 JP 7-324801 A

  The conventional air outlet device is configured as shown in each of the above-mentioned patent documents. Especially when the latter floor air outlet device is adopted, even in a condition where the indoor space is large, it is necessary for a place where air conditioning is actually required. Air conditioning can be executed locally by blowing out the conditioned air directly, and an increase in air conditioning costs can be avoided.

  However, even in the case of performing air conditioning using a conventional floor outlet device, if the indoor space is large, for example, during heating, the conditioned air that is blown out escapes above the living area. Since it progresses and diffuses not only around the people in the area but also in each part of the indoor space, it has been difficult to efficiently obtain a comfortable state for people in the living area.

  The present invention has been made in order to solve the above-mentioned problems. The temperature adjustment for the area where the person exists is performed by keeping the temperature-adjusted air that has reached the surroundings of the person in the living area as close as possible to the person. An object of the present invention is to provide an air conditioning system that secures capability and enables efficient air conditioning even in a large indoor space.

  An air conditioning system according to the present invention includes a canopy portion having a continuous surface that generates a recess having a predetermined size, and being disposed at a position away from the floor of an indoor space with the opening side of the recess facing downward.

  As described above, according to the present invention, the canopy portion is disposed above the position determined as the position where the person exists in the indoor space, and the air temperature adjusting device is provided on the floor below the canopy portion. When the air whose temperature has been changed by the temperature adjusting device advances upward and reaches the downward concave portion of the canopy portion, the air whose temperature has been changed is captured and stays in this concave portion, and the air further proceeds upward, In addition, the air whose temperature has been changed by the air temperature adjusting device continues to be affected as much as possible by the temperature change in the lower region of the canopy by preventing the mixing with the indoor air above and from the canopy. Suppresses the thermal influence from the indoor air at different temperatures above and prevents the air conditioning effect from being reduced by the air in the recess, so that the ambient temperature of the person in the lower area of this canopy is moderate. State It will be able to adjust maintained, can be performed efficiently air conditioning to the region in the presence of each person in the indoor space.

  Moreover, the air conditioning system which concerns on this invention enables the said canopy part to adjust an installation position to an up-down direction between the floor and ceiling of indoor space as needed.

By changing the direction downward, the air whose temperature has been changed by the air temperature adjusting device causes a flow toward the lower region of the canopy part through the concave part of the canopy part, and the air whose temperature has been changed is the canopy part Thus, the state of staying below the canopy portion and bringing the temperature of the lower region of the canopy close to the temperature of the air is reliably continued, so that air conditioning can be performed more efficiently to bring the region where a person exists to a desired temperature state.

  Moreover, the air conditioning system which concerns on this invention makes the said canopy part the shape which bent the peripheral part outward in the shape of a bowl as needed.

  As described above, according to the present invention, the peripheral part of the canopy part is bent outward, and the airflow reaching the peripheral part of the canopy part from below is easily directed to the concave part side of the canopy part, while the canopy part is provided from above. When the airflow reaching the peripheral part of the air is guided in a direction away from the canopy part, the air whose temperature has been changed by the air temperature adjustment device moves upward and reaches the peripheral part of the canopy part The air can enter the concave portion of the canopy portion to secure a state in which the temperature of the lower region of the canopy portion is affected, and the room air above the canopy portion has a temperature different from that of the concave portion of the canopy portion. However, if a situation occurs that flows downward along the outer periphery of the canopy, this indoor air flow should be guided laterally along the periphery of the canopy and advanced away from the canopy. And the airflow from the room air is below the canopy. Will be away from the band, can avoid affecting the air conditioning state in the lower side of the canopy portion is enhanced and the effect to promote efficient air conditioning by the air of varying temperature at an air temperature adjusting device.

  As described above, according to the present invention, the canopy portion has a rotationally symmetrical shape with a deformable structure combining the bone portion and the membrane portion, and the inclination of each portion of the canopy portion with respect to the central axis of symmetry of the canopy portion is uniformly adjusted. The degree to which the shape of the canopy can be changed and the shape of the recess can be changed, so that the shape of the canopy is appropriately changed according to the state of the air in the recess, and the recess remains shallow and the air remains. Can be adjusted to increase the degree of air retention by deepening the concavity or conversely, and even during installation and use of the canopy, A desired air-conditioning state can be easily obtained in the side region.

  Further, in the air conditioning system according to the present invention, if necessary, the canopy portion is formed of a material that is hard and can maintain its shape, and a bone portion that is arranged at a plurality of predetermined intervals according to the shape of the recess.

(First embodiment of the present invention)
Hereinafter, an air conditioning system according to a first embodiment of the present invention will be described with reference to FIGS. In the present embodiment, an example of an air conditioning system will be described in which a region in which a person exists in a large indoor space such as a factory having a large ceiling height is targeted for air conditioning.

  In each of the drawings, the air conditioning system 1 according to the present embodiment is a canopy portion that is disposed at a position away from the floor 60 in the indoor space 50 and at a location directly above a person's seating position or dedicated work space. 10 and an air temperature adjusting device 15 disposed on the floor 60 below the canopy 10.

  The canopy 10 has a continuous surface that generates a recess 14 of a predetermined size having a substantially semicircular cross-sectional shape, and has a shape that is rotationally symmetric about a predetermined center axis, specifically a substantially hemisphere. It is a shell-like configuration that is disposed at a position away from the floor 60 in the indoor space with the opening side of the recess 14 facing downward. The size of the canopy portion 10 is such that the lower end diameter is about 2 to 4 m so that the area below the canopy portion 10 includes the activity range of a person sitting or standing. Is preferable.

  The canopy portion 10 is formed of a hard material that can maintain its shape, and is formed of an annular bone portion 11 that is arranged at a predetermined interval according to the shape of the concave portion 14 and a flexible sheet material. And a membrane portion 12 which is arranged in an expanded state along each bone portion 11 and forms a continuous surface where the inside becomes the concave portion 14.

  The bone portions 11 are arranged in a ring shape with different diameters, and are arranged at predetermined intervals in the vertical direction in order of the diameter while matching the horizontal position of the center of the circle. This is a mechanism for forming the substantially hemispherical canopy 10 by integrating the membrane 12.

  When the canopy portion 10 is not used, if the membrane portion 12 is bent so that the bone portions 11 having different diameters are arranged concentrically, the canopy portion 10 can be shrunk vertically to form a thin and flat shape. It will be in a state suitable for storage and movement. Further, in the case where the annular bone portion 11 has a splittable structure in which a plurality of arcuate members are joined and integrated by joints, the membrane portion formed by the bone portion 11 is released by uncoupling the members forming the bone portion 11. By relaxing the restraint of 12, the canopy 10 can be made foldable, and further compaction can be achieved during storage and movement.

  A projecting portion 13 having a curved surface that is smoothly continuous with the inner surface of the canopy portion 10 and having a convex shape downward is attached to the inside of the concave portion 14 of the canopy portion 10. The projecting portion 13 changes the traveling direction downward while advancing the air flow traveling along the recess 14 along the inner surface of the canopy portion 10 along the surface of the projecting portion to advance toward the center of the recess. In this mechanism, the air is directed toward the lower region of the canopy 10.

  The canopy 10 is positioned with the protrusion 13 attached, and the central portion (symmetrical central axis position) of the canopy 10 is located directly above the position where a person is usually sitting or standing. It is arranged and supported by being suspended so that the arrangement position can be adjusted in the vertical direction between the floor and the ceiling of the indoor space 50.

  The vertical position of the canopy 10 is in a range from the height at which the lower end position of the canopy 10 slightly exceeds the height of the person (the height that does not hinder people's traffic) to the height of 4 m from the floor. It is preferable to do so. When the position of the canopy portion 10 is increased, the effect of the canopy portion 10 in air conditioning is weakened, and the effect of air conditioning is reduced. On the contrary, if the position of the canopy 10 is lowered, the effect of the canopy 10 in the air conditioning becomes stronger, and the effect of the air conditioning increases.

The air temperature adjusting device 15 is disposed on the floor 60 below the canopy 10 in the indoor space 50, and moves the air changed to a temperature different from the indoor air upward.
Specifically, the air temperature adjusting device 15 includes a floor outlet device 16 that blows upward conditioned air supplied through a space under the floor from an opening provided in the floor 60, and a duct under the floor to the space under the floor. A heat transfer section 17 that exchanges heat between the indoor heat and the heat transfer surface of the floor that changes the temperature by heat conduction with the conditioned air that circulates the indoor air. .

  The floor outlet device 16 is disposed at two locations in a circular area directly below the canopy portion 10 on the floor 60, and blows upward conditioned air supplied through the underfloor space to the concave portion 14 of the canopy portion 10. The conditioned air can be reached.

  The floor air outlet device 16 is disposed at a position close to the end in the circular region directly below the canopy 10 so that the conditioned air blown upward is placed on a person located below the center of the canopy. It is desirable not to hit directly but to reach the recess 14 of the canopy 10 while preventing drafting.

  The heat transfer section 17 also serves as a flooring material. The conditioned air flowing through the underfloor space is brought into contact with the lower surface, and heat transfer between the lower conditioned air and the upper surface facing the indoor space is conducted. By changing the temperature of the heat transfer surface (floor surface), due to the temperature change due to the direct heat transfer to the air in contact with the heat transfer surface and the heat radiation from the heat transfer surface to the air This is a mechanism for generating a temperature change by releasing heat or absorbing heat by receiving heat radiation from the air at the heat transfer surface.

  Next, the execution state of the air conditioning in the air conditioning system based on the said structure is demonstrated. As a premise, the canopy unit 10 is disposed in the indoor space 50 immediately above a predetermined position serving as a person's seating position or a dedicated work space, with the height position adjusted in advance so as to obtain an appropriate air-conditioning state. It shall be.

  In a state in which air conditioning to the indoor space is performed, conditioned air is continuously supplied from the underfloor space to the floor outlet device 16 of the air temperature adjusting device 15, and the conditioned air is directed upward from the floor outlet device 16. To blow out. Further, the heat transfer unit 17 is changed to a temperature different from the temperature of the room air due to the influence of the heat of the conditioned air, and the heat transfer unit 17 is changed to the upper side by heat transfer or heat radiation based on a temperature difference with the room air. Change the temperature of room air. Then, the conditioned air blown out from the floor outlet device 16 rises, reaches the upper canopy 10, and flows into the recess 14.

  In the case of heating, the heat transfer section 17 is warmed from the lower floor side due to the influence of warm conditioned air, changes in temperature, and is warmer than room air. The heat transfer unit 17 heats the human feet with heat radiation, and also warms the indoor air above the heat transfer unit directly with heat transfer and heat radiation.

  Further, the warm conditioned air blown out from the floor outlet device 16 and reaches the concave portion 14 of the canopy portion 10 travels upward along the inner surface of the canopy portion 10, and then gradually moves downward in the direction of travel by guidance by the protruding portion 13. In other words, it reaches the lower region of the canopy part 10 and partly diffuses to increase the temperature of the lower region of the canopy part, and the rest from the peripheral part away from the position directly above the floor outlet device 16 of the canopy part 10. It flows out to the area | region outside the canopy part 10, and will spread | diffuse to circumference | surroundings, progressing indoor space further upwards.

  In this way, a state in which warm conditioned air stays below the canopy 10 is obtained, and if the canopy 10 is not provided, the indoor space 50 with a high ceiling ascends as it is and reaches the vicinity of the ceiling 70. The area under the canopy 10 can be warmed by effectively utilizing the conditioned air that cannot sufficiently warm the living area. Further, the canopy 10 isolates the room air above the canopy 10 from the area below the canopy 10 and the upper room air thermally affects the area below the canopy 10. To prevent. Furthermore, the room air heated by the heat transfer unit 17 naturally rises to reach the canopy unit 10 and becomes an ambient atmosphere of the person, thereby preventing the room air having a lower temperature from approaching the person.

  Thereby, the area where the person below the canopy 10 is present can be maintained in an air conditioned state warmer than the surrounding indoor space, and each person in the indoor space can perform the air conditioning of the entire indoor space. A heating effect is given to the area where the air is present, and the efficiency of air conditioning is increased.

  On the other hand, in the case of cooling, due to the influence of the conditioned air having a low temperature, the heat transfer section 17 is cooled from the underfloor side and changes in temperature, and is in a state where the temperature is lower than the room air. The heat transfer unit 17 takes heat by receiving heat radiation from a person's feet and the surrounding indoor air, and also transfers heat by direct heat transfer from the indoor air on the upper side of the heat transfer unit. The surrounding room air will be cooled.

  In addition, the conditioned air that is blown out from the floor outlet device 16 and reaches the concave portion 14 of the canopy portion 10 travels upward along the inner surface of the canopy portion 10, and then gradually advances in the direction of travel by guidance by the protruding portion 13. It changes to the downward direction, reaches the lower region of the canopy 10, and lowers the temperature of the lower region of the canopy while diffusing into the indoor space.

  Thus, a state in which conditioned air having a low temperature stays below the canopy portion 10 is obtained, the area below the canopy portion 10 is cooled, and the indoor air and the canopy portion 10 are located above the canopy portion 10. It isolates | separates from the area | region of the lower side, and prevents that the indoor air whose temperature is higher above has a thermal influence on the area | region of the lower side of the canopy part 10. FIG. In addition, the indoor air that has been mixed and cooled with the conditioned air at the lower side of the canopy 10 naturally descends and becomes a human ambient atmosphere, thereby preventing the higher temperature indoor air from approaching the person. .

  Thereby, the area | region where the person under the canopy part 10 exists can be maintained in the air conditioning state whose temperature is lower than the surrounding indoor space, and the air conditioning of the whole indoor space is performed like the case of heating. Nonetheless, a cooling effect is given to the area where each person exists in the indoor space, and the efficiency of air conditioning can be increased.

  As described above, in the air conditioning system according to the present embodiment, the canopy 10 is disposed above the position determined as the position where the person is present in the indoor space 50, and the floor 60 below the canopy 10 is disposed on the floor 60. When the air temperature adjusting device 15 is provided, and the air whose temperature has been changed by the air temperature adjusting device 15 advances upward and reaches the downward concave portion 14 of the canopy portion 10, the air whose temperature has been changed in the concave portion 14. The trapped air stays in a state where the air further moves upward and prevents the air from mixing with the upper room air. Therefore, the air whose temperature has been changed by the air temperature adjusting device 15 is the area below the canopy 10. While maintaining as much as possible the state of affecting the temperature of the air, the thermal effect from the indoor air having a different temperature above the canopy 10 is suppressed, and the air conditioning effect by the air in the recess 14 is suppressed. The temperature of the ambient atmosphere of the person existing in the lower region of the canopy 10 can be adjusted and maintained in an appropriate state, and the air conditioning is efficiently performed on the region where each person exists in the indoor space 50. Can be executed.

  In the air conditioning system according to the embodiment, the peripheral portion of the canopy portion 10 is configured to be formed substantially downward as the end portion of the hemispherical shell, but not limited thereto, as shown in FIG. It can also be set as the structure formed in the shape which bent the peripheral part 18 of the canopy part 10 in the outward hook shape.

  In this case, the peripheral edge 18 facilitates the airflow rising from the bottom and reaching the peripheral edge 18 toward the concave portion 14 side of the canopy section 10, while the airflow descending from the top and reaching the peripheral edge 18 is covered with the canopy. It will be in the state which leads to the direction which leaves | separates from the part 10. FIG. Thereby, when the conditioned air that has advanced upward from the floor outlet device 16 of the floor 60 reaches the peripheral edge 18 of the canopy 10, the conditioned air is directed toward the concave portion 14 of the canopy 10 at the peripheral 18. , And more conditioned air can enter the recess 14 to ensure a state in which the region below the canopy 10 has an influence from the conditioned air.

  In addition, when a situation occurs in which the indoor air above the canopy 10, which has a temperature different from that of the conditioned air in the concave portion 14 of the canopy 10, flows downward along the outer periphery of the canopy 10, this indoor air flow Can be guided in the lateral direction along the peripheral edge 18 of the canopy 10 and can be moved away from the canopy 10, and the airflow of such room air is separated from the region below the canopy 10, The influence on the air conditioning state on the lower side of the canopy 10 can be avoided, and the air conditioning by the conditioned air can be efficiently advanced.

  Moreover, in the air conditioning system which concerns on the said embodiment, although it is set as the structure provided with the floor outlet apparatus 16 and the heat-transfer part 17 as the air temperature adjustment apparatus 15 of the lower side of the canopy part 10, it is not restricted to this, Either one may be sufficient. In addition, if such an air temperature adjusting device can change the temperature of indoor air above the floor, for example, a floor cooling device that cools the floor surface by passing a refrigerant such as cold water through the floor, or heat such as hot water A floor heating device that passes the medium through the floor to warm the floor, a heater embedded in the floor, a hot carpet laid on the floor, or the like may be used.

  Moreover, in the air conditioning system which concerns on the said embodiment, the protrusion part 13 provided in the center part lower side of the canopy part 10 is set as the structure made into the state which maintained the initial shape, while using the air conditioning system. However, the present invention is not limited to this, and the protruding portion may be made of a deformable material so that the lower end position of the protruding portion and the curvature of the surface can be changed as necessary.

  In this case, the behavior of the conditioned air flow guided downward from the recess 14 to the projection can be adjusted by the deformed projection, and the canopy can be used even when the canopy 10 is installed and used. The desired air-conditioning state can be easily obtained in the lower region of the canopy unit 10 by appropriately deforming the protrusion so as to correspond to the actual air-conditioning situation on the lower side of the unit and the surrounding situation. be able to.

(Second embodiment of the present invention)
Further, in the air conditioning system according to the first embodiment, the canopy portion 10 is maintained and fixed in a hemispherical shell shape during use and is not deformed. As shown in FIGS. 7 to 10, the canopy portion 10 has a common shape in which the canopy portion is rotationally symmetric about a predetermined central axis, but the arrangement of the bone portions is changed to change the canopy portion 10. The bone portions 11a are radially arranged around the central axis of the canopy, and the bone portions 11a of the canopy portion 10 are supported to be tiltable relative to the central axis CA of the canopy portion 10, and the membrane portion 12 is supported by the bone. It is also possible to adopt a configuration in which the inclination of each part of the canopy part with respect to the central axis CA can be adjusted uniformly so as to be able to expand and contract following the inclination of the part 11a.

  Specifically, the bone portion 11 a has a substantially arcuate curved shape corresponding to the cross-sectional shape of the recess 14, and a plurality of the bone portions 11 a are arranged radially around the symmetrical central axis CA of the canopy portion 10. And each bone part 11a in the canopy part 10 is mutually connected so that it can incline relatively with respect to the central axis CA, and the inclination with respect to the central axis of each bone part 11a is adjustable, and the canopy part A state is obtained in which the inclination of each part with respect to the central axis CA can be adjusted uniformly.

  In this case, the bone part 11a is tilted like an umbrella to uniformly adjust the inclination of each part of the canopy part with respect to the central axis CA, and the shape of the canopy part 10 is changed while maintaining its rotational symmetry point. By doing so, the shape of the recess 14 is also changed. For example, when the inclination of the canopy part 10 with respect to the central axis of the bone part 11a is increased, the hemispherical shell is vertically crushed and the spread is increased, and the recessed part 14 becomes shallow, and the degree of conditioned air retention decreases. (See FIG. 9). Conversely, when the inclination of the bone part 11a with respect to the central axis CA is reduced, the canopy part 10 has a shape in which the hemispherical shell is squeezed from the periphery to reduce the spread, and the recessed part 14 is deepened to increase the degree of conditioned air retention ( (See FIG. 10). Thus, the shape change of the canopy portion 10 is appropriately given, the shape of the recess portion 14 is changed, and the behavior of the conditioned air flow in the recess portion 14 can be adjusted. A desired air-conditioning state can be easily obtained in the lower region of the canopy 10 through the adjustment according to the actual air-conditioning condition on the lower side of the canopy part and the surrounding conditions.

  In addition, instead of deforming the canopy portion 10 by tilting the bone portion 11a of the canopy portion 10 with respect to the symmetric central axis, the bone portions 11b arranged radially around the symmetric central axis CA are elastic. After making the material easy to deform, the degree of curvature of each bone portion can be adjusted uniformly, and the membrane portion 12 can be stretched and deformed following the deformation of each bone portion. It is also possible to adopt a configuration in which deformation is generated so as to change the curvature of the curved surface. In this case, as shown in FIG. 11, when the degree of curvature of the bone portion 11 b is reduced and the curvature of the canopy portion is reduced, the canopy portion 10 has a shape in which the hemispherical shell is crushed vertically to increase the spread, and the recess 14 Becomes shallower, and the degree of conditioned air retention decreases. Conversely, as shown in FIG. 12, when the degree of curvature of the bone portion 11b is increased and the curvature of the canopy portion is increased, the canopy portion 10 has a shape in which the hemispherical shell is squeezed from the periphery to reduce the spread, and the recess 14 Becomes deeper and the degree of staying of conditioned air becomes stronger.

(Third embodiment of the present invention)
Moreover, in the air conditioning system which concerns on the said 1st Embodiment, although the canopy part 10 is set as the structure made into the substantially hemispherical shell shape which makes a rotational symmetry in use condition, it is not restricted to this, 3rd As an embodiment, as shown in FIG. 13 and FIG. 14, for example, while changing the overall shape of the canopy part, the cross-sectional shape is a shape having a continuous surface that generates a recess having a substantially semicircular shape, It can also be set as the structure in which a canopy part makes a substantially semi-cylindrical shape.

  Specifically, the canopy 20 has a continuous surface that generates a recess 24 of a predetermined size having a substantially semicircular cross-sectional shape, and has a shape that is line-symmetric with respect to a predetermined center line CL. Specifically, it has a substantially semi-cylindrical shape and is disposed at a position away from the floor 60 in the indoor space with the opening side of the recess 24 facing downward.

  The canopy portion 20 is made of a hard material capable of maintaining its shape, and a plurality of rectangular frame-shaped bone portions 21 arranged at predetermined intervals according to the shape of the concave portion 24, and a flexible sheet material And a membrane portion 22 that is arranged in a stretched state along each bone portion 21 and forms a continuous surface where the inside becomes the recess 24.

  The bone portions 21 are arranged with different frame shapes arranged side by side at predetermined intervals in the order of size while matching the horizontal position of the center of the frame. And the film part 22 are integrated to form a substantially semi-cylindrical canopy part 20.

  When the canopy portion 20 is not used, the canopy portion 20 can be moved up and down as in the first embodiment by bending the membrane portion 22 so that the bone portions 21 having different sizes are arranged inside and outside. Can be shrunk into a thin and flat shape, which is suitable for storage and movement. In addition, when the rectangular frame-shaped bone portion 21 has a splittable structure in which a plurality of linear members are connected and integrated by joints, the members of the bone portion are disconnected to form a membrane portion by the bone portion. By relaxing the constraint, the canopy portion 20 can be folded, and further compaction can be achieved during storage and movement.

  On the lower side of the center portion inside the concave portion 24 of the canopy portion 20, the canopy portion 20 has a curved surface that is smoothly continuous with the inner surface that is the curved surface of the canopy portion 20 and that continues in the direction of the symmetrical center line CL, and is convex downward. A horizontally long protrusion 23 is attached. The projecting portion 23 changes the traveling direction downward while advancing the air flow traveling along the recess 24 along the inner surface of the canopy portion 20 along the surface of the projecting portion to advance toward the center of the recess. In this mechanism, the air is directed toward the lower region of the canopy 20.

  The canopy 20 has the projection 23 attached, and the center of the canopy 20 (symmetrical center line CL position) is located directly above the position where a person is usually sitting or standing. And the suspension position is supported by being suspended so that the arrangement position can be adjusted in the vertical direction between the floor and the ceiling of the indoor space 50.

  As with the first embodiment, a floor outlet device 26 and a heat transfer unit 27 are disposed on the lower floor 60 of the canopy unit 20 as the air temperature adjusting device 25 as in the first embodiment. Of these, the floor outlet device 26 corresponds to the canopy portion 20 having a substantially semi-cylindrical shape, and the central portion (symmetrical) of the canopy portion 20 in the rectangular region directly below the canopy portion 10 on the floor 60. The center line CL position is disposed at two locations at the end portions that are separated from the position directly below the center line CL position.

  Also in the air conditioning system according to the third embodiment, the canopy portion 20 is disposed above the position determined as the position where the person is present in the indoor space 50, as in the first embodiment, and the canopy portion 20. The air temperature adjusting device 25 is provided on the lower floor 60, and when the air whose temperature has been changed by the air temperature adjusting device 25 proceeds upward and reaches the downward recessed portion 24 of the canopy portion 20, the recessed portion 24. The air whose temperature has been changed is trapped and stays in the air, and further progress of the air and mixing with the indoor air above the air are prevented. While maintaining as much as possible the state in which the temperature change is exerted on the lower region of the canopy 20, the thermal influence from indoor air having a different temperature above the canopy 20 is suppressed, and the recess 24 It is possible to prevent the air conditioning effect from being reduced by the air, and to adjust and maintain the temperature of the ambient atmosphere of the person existing in the lower region of the canopy 20 to an appropriate state. Air conditioning can be performed efficiently.

  In addition, even if the semi-cylindrical canopy part 20 is provided with an air temperature adjusting device 25 on the lower side of the canopy part 20 even when the length of the symmetrical centerline direction is appropriately set, As in the first embodiment, air conditioning can be performed on the lower region of the canopy 20. For this reason, when the seating positions or dedicated work spaces of a plurality of persons in the indoor space 50 are arranged in a line in a relatively close state, the substantially hemispherical canopy part 10 as in the first embodiment is used. If there is a situation where the installation space cannot be secured if installation is attempted at each position where a person is present and installation is impossible, there are a plurality of positions where the person exists in the symmetric center line CL direction of the canopy portion 20. If the canopy 20 has a long semi-cylindrical shape extending in the direction of the symmetric center line so as to cover all the continuous ranges of positions where people are present, it is possible to match the positions where a plurality of people exist. Thus, the single canopy unit 20 can cope with the problem without any problem, and air conditioning can be performed without difficulty to the area below the canopy unit 20 including the positions where a plurality of people exist.

(Fourth embodiment of the present invention)
Further, in the air conditioning system according to the third embodiment, the canopy portion 20 is maintained and fixed in a semi-cylindrical shape during use, and is not deformed. As shown in FIG. 15 to FIG. 17, the canopy portion is arranged in a line-symmetric shape with a predetermined center line CL in between, and the arrangement of the bone portions is changed to change the arrangement of the canopy portion 20. Bone portions are separately arranged on both sides of the symmetric center line CL, and one canopy portion 21a existing in one region of the canopy portion 20 of the canopy portion 20 divided into two by the symmetric center line CL 20 is supported so as to be able to tilt relative to the other bone portion 21b existing in the other region of 20, and the membrane portion 22 can be stretched and deformed following the tilting of the bone portion. The angle with the other area is adjustable. It is also possible.

  Specifically, the bone portions 21 a and 21 b have a substantially arcuate curved shape corresponding to the cross-sectional shape of the recess 24, and a plurality of the bone portions 21 a and 21 b are arranged side by side in the direction of the center line on both sides of the symmetrical center line CL of the canopy portion 20. The And it connects so that one bone part 21a in the canopy part 20 can be tilted relatively with respect to the other bone part 21b, and the angle which one bone part 21a and the other bone part 21b make is adjustable. Thus, a state is obtained in which the angle formed by one region and the other region of the canopy portion 20 can be adjusted.

  In this case, the bone portions 21a and 21b are tilted together to adjust the angle formed by one region and the other region of the canopy portion 20, and the shape of the canopy portion 20 is maintained at the point of being line symmetric. The shape of the recess 24 can also be changed by changing it. For example, when the angle between the one bone portion 21a and the other bone portion 21b is increased, the canopy portion 20 has a shape in which the semi-cylinder is crushed vertically to increase the spread, and the concave portion 24 becomes shallow so that conditioned air is retained. Will be weakened (see FIG. 16). On the contrary, when the angle formed by one bone portion 21a and the other bone portion 21b is reduced, the canopy portion 20 has a shape in which the semi-cylinder is crushed sideways to reduce the spread, and the concave portion 24 becomes deeper and the conditioned air becomes deeper. The degree of retention increases (see FIG. 17). Thus, the shape change of the canopy part 20 is appropriately given, the shape of the recess 24 is changed, and the behavior of the conditioned air flow in the recess 24 can be adjusted, and the canopy part 20 is installed and used. A desired air-conditioning state can be easily obtained in the lower region of the canopy 20 through the adjustment according to the actual air-conditioning condition on the lower side of the canopy unit 20 and the surrounding conditions.

  In addition, instead of the configuration in which the canopy 20 is deformed by tilting the bones 21a and 21b so as to adjust the angle formed by one bone 21a and the other bone 21b, the canopy 20 can be changed. The respective bone portions 21c and 21d arranged in a plurality in the direction of the center line CL on both sides of the symmetrical center line CL of the portion 20 are made of a material that is easily elastically deformed, and the bending degree of each of the bone portions 21c and 21d is determined. The film portion 22 is made adjustable so that it can be stretched and deformed following the deformation of the bone portions 21c and 21d so that the curvature of the continuous curved surface of the canopy portion 20 is changed. You can also. In this case, as shown in FIG. 18, when the degree of curvature of the bone portions 21 c and 21 d is reduced and the curvature of the canopy portion 20 is reduced, the canopy portion 20 has a shape in which the half cylinder is crushed vertically and the spread is increased. The concave portion 24 becomes shallow, and the degree of staying of conditioned air is weakened. Conversely, as shown in FIG. 19, when the curvature of the bone portions 21c and 21d is increased and the curvature of the canopy portion 20 is increased, the canopy portion 20 has a shape in which the semi-cylinder is crushed sideways to reduce the spread. The concave portion 24 becomes deeper and the degree of staying of the conditioned air increases.

  In the air conditioning system according to each of the first to fourth embodiments, the projecting protrusions 13 and 23 are provided below the center of the canopy parts 10 and 20, and the traveling direction of the conditioned air is directed downward. However, the present invention is not limited to this. For example, when the shape of the canopy section can independently guide the conditioned air flow in a desired direction such as downward, no protrusion is provided. It does not matter as a configuration.

  Moreover, in the air conditioning system according to each of the first to fourth embodiments, the canopy parts 10 and 20 have a symmetrical shape, and the protruding parts 13 and 23 are provided at locations that are symmetrical centers. If the position where people are present in the area below the canopy is biased from the center of the area, or if the floor outlet is not symmetrically arranged in the area below the canopy, the floor outlet is blown out. If the speed of the conditioned air flow is large, and the conditioned air flow that has changed the direction of travel at the protruding part goes down as it is, the person feels as a draft, etc. It is also possible to provide a configuration in which the protruding portion is provided at a position removed from the center of the canopy portion, and the airflow of conditioned air is guided to an arbitrary location by the protruding portion.

  Further, in the air conditioning system according to each of the first to fourth embodiments, the canopy portions 10 and 20 are configured to have a shape that generates the concave portions 14 and 24 having a substantially semicircular cross-sectional shape. Not limited to this, as long as a recess capable of retaining conditioned air can be generated, the recess has a cross-sectional shape other than a substantially semicircular shape, for example, the canopy has a half-square cylindrical shape, or a bottom-open hollow shape. A conical shape or a hollow frustum shape may be used.
