And the floor outlet 14 may be arrange | positioned in the separate space 41 divided by the partition 4, and may be arrange | positioned on another floor surface. The suction port 15 is a member that allows the ceiling back space 31 and the room 3 to communicate with each other, and is attached to an opening provided in the ceiling 34. The suction port 15 is also constituted by a plate material or the like in which slits and vent holes are formed.

  The partition 4 that divides the individual space 41 has, for example, a left panel 42 disposed on the left side, a front panel 43 disposed on the front surface, and a right panel 44 disposed on the right side, as shown in FIG. The panels 42 to 44 are arranged so as to be U-shaped in plan view. In FIG. 2 and FIGS. 8 and 9 described later, a part of the right panel 44 is notched for convenience of explanation.

  The partition 4 defines an individual space 41 that is open at the top and rear. And the rear part in the individual space 41 becomes a person's entrance. In the illustrated partition 4, the length in the front-rear direction of the right panel 44 is shorter than the length in the front-rear direction of the left panel 42, and the entrance is widened accordingly.

  In the individual space 41, fixtures such as a work desk 51 and a cabinet 52 are arranged. The work desk 51 has a top plate 51a and leg portions 51b. As will be described later, the top plate 51a functions as an indirect radiation portion that indirectly radiates heat. A rectangular plate material made of wood, metal, glass or the like is used for the top plate 51a. The width of the top plate 51a is determined to be about the same as the width of the front panel 43 (length in the left-right direction), and the depth of the top plate 51a is about the same as the width of the right panel 44 (length in the front-rear direction). Determined. Further, the thickness of the top plate 51a is set to such a degree that the top plate 51a does not bend and the rigidity necessary for the work is obtained. The leg portions 51b are members that support the top plate 51a, and in the present embodiment, are constituted by four prismatic members, and are attached to the four corners of the top plate 51a one by one.

  As shown in FIG. 1, the individual air conditioning unit 2 includes a heat source device 21, a first heat medium supply pipe 22, a second heat medium supply pipe 23, a heat medium outlet 24, a first heat medium hose 25, and a second heat medium hose. 26, a convection generating panel 27 is provided.

  The heat source unit 21 is a part that adjusts the temperature of the heat medium independently of the control temperature by the indoor air-conditioning unit 1, and corresponds to a heat source unit for the heat medium. The heat medium determines the operating temperature of the convection generating panel 27. In the present embodiment, water is used as the heat medium. The heat source device 21 is heated to heat water during heating, and is cooled to cool water during cooling. The heat medium whose temperature is adjusted by the heat source device 21 includes the first heat medium supply pipe 22, the second heat medium supply pipe 23, the heat medium outlet 24, the first heat medium hose 25, and the second heat medium hose 26. To the convection generating panel 27.

  The first heat medium supply pipe 22 and the second heat medium supply pipe 23 cause the heat medium to flow between the heat source device 21 and the heat medium outlet 24. For this reason, these supply pipes are arranged in the underfloor space 32. In the present embodiment, the first heat medium supply pipe 22 causes the heat medium to flow from the heat source apparatus 21 to the heat medium outlet 24, and the second heat medium supply pipe 23 causes the heat medium to flow from the heat medium outlet 24 to the heat source apparatus 21. . The heat medium outlet 24 has a connection part (not shown) to which the first heat medium hose 25 and the second heat medium hose 26 are connected. The heat medium outlet 24 closes the opening of the connection portion so that the heat medium in the heat medium supply pipes 22 and 23 does not leak outside in a state where the heat medium hoses 25 and 26 are not connected. In the state where the medium hoses 22 and 23 are connected, the opening of the connection portion is opened so that the heat medium flows between the heat medium supply pipes 22 and 23 and the heat medium hoses 25 and 26. ing.

  The first heat medium hose 25 and the second heat medium hose 26 are for flowing the heat medium between the heat medium outlet 24 and the convection generating panel 27, and are constituted by, for example, a flexible tubular member. The The first heat medium hose 25 is connected to the first heat medium supply pipe 22, and the second heat medium hose 26 is connected to the second heat medium supply pipe 23. Therefore, the heat medium supplied from the heat source device 21 is guided to the convection generating panel 27 through the first heat medium supply pipe 22 and the first heat medium hose 25. On the other hand, the heat medium discharged from the convection generation panel 27 is returned to the heat source device 21 through the second heat medium hose 26 and the second heat medium supply pipe 23 and is supplied to the convection generation panel 27 again. As described above, the heat medium whose temperature is adjusted by the heat source device 21 is used by circulating between the heat source device 21 and the convection generating panel 27.

  Next, the convection generating panel 27 will be described.

  The convection generating panel 27 is a member corresponding to the convection generating portion, and is attached to the surface (inner surface) of the partition 4 on the individual space 41 side. FIG. 2 shows a usage state during cooling (a usage state for lowering the temperature of the individual space 41). In this use state, the convection generating panel 27 is arranged above the left panel 42, that is, above the top plate 51 a of the work table 51 by the upper mounting hook 28 </ b> A (upper mounting tool).

  As shown in FIG. 3, the convection generating panel 27 includes a heat medium pipe 27a, heat transfer fins 27b, and a convection regulating plate 27c. The heat medium pipe 27a is a member through which the heat medium flows, and is configured by a tubular member having heat conductivity, for example, a metal pipe (iron pipe, stainless steel pipe, copper pipe, aluminum pipe) having an inner diameter of about 1 cm. The heat transfer fins 27b correspond to heat transfer members, and transfer heat from the heat medium transmitted through the heat medium pipe 27a to the space around the heat medium pipe 27a. The heat transfer fin 27b is, for example, a wire wound in a rectangular coil shape, and is wound spirally around a metal pipe. And the heat transfer fin 27b gives a temperature change to the air in the vicinity of the heat transfer fin 27b, so that convection occurs in the air around the heat medium pipe 27a.

  The convection regulating plate 27c is a plate-like member that sandwiches the heat medium pipe 27a around which the heat transfer fins 27b are wound. In the present embodiment, a plurality of heat medium pipes 27a that are parallel to each other and spaced apart from each other are fixed in a state of being sandwiched between a pair of convection restriction plates 27c. As will be described later, the direction of the air convection generated around the heat medium pipe 27a is restricted between the pair of convection restriction plates 27c by the convection restriction plate 27c.

  Each heat medium pipe 27 a is disposed between the first heat medium hose 25 and the second heat medium hose 26, and the heat medium supplied from the first heat medium hose 25 is discharged to the second heat medium hose 26. Connected to be.

  As described above, the convection generating panel 27 is attached to the surface of the partition 4. At this time, the heat medium pipes 27 a are arranged in the vertical direction. This is to generate convection. That is, convection is generated due to the temperature difference of the air, but when the heat medium pipes 27a arranged at intervals are arranged in the vertical direction, the space in which the heat medium pipes 27a and the heat transfer fins 27b are disposed and the heat medium pipes 27a A temperature difference is generated between the space where no etc. are arranged. At this time, the relatively warm air rises and the cold air falls. Since the air rises and falls at a plurality of locations in the vertical direction of the convection generating panel 27, convection occurs. In addition, since the heat medium pipe 27a and the like are sandwiched between the pair of convection regulating plates 27c, the convection direction can be regulated so as not to diffuse.

  As a result, during cooling, as shown by an arrow in FIG. 4, the cold air generated inside the convection generating panel 27 flows downward along the inner surface of the partition 4 (left panel 42). And when this cold air reaches the surface of the top plate 51a, it spreads along the upper surface of this top plate 51a and cools the top plate 51a from the surface side.

  Next, the operation of the air conditioning system will be described.

  In the air conditioning system of this embodiment, the indoor air conditioning unit 1 and the individual air conditioning unit 2 are used in combination. As shown in FIGS. 5 to 7, the indoor air conditioner 1 uniformly cools the room 3 during cooling. For example, it is cooled to about 28 ° C. The air cooled by the air conditioner 11 flows through the lower air conditioning duct 13 and is supplied from below into the individual space 41 from each of the floor outlets 14, for example. The individual space 41 surrounded by the partition 4 is cooled by the cold air supplied from the floor outlet 14.

  On the other hand, the individual air conditioning unit 2 cools each individual space 41 individually. For example, the temperature of the individual space 41 in charge is adjusted by circulating a heat medium (cold water) that has been cooled to a temperature that is lower than the set temperature in the indoor air-conditioning unit 1 by a predetermined temperature (around 5 ° C.). For example, when the set temperature in the indoor air conditioning unit 1 is 28 ° C., cold water cooled to about 23 ° C. from 20 ° C. that does not cause surface condensation is circulated. As described above, due to the circulation of the heat medium, cool air flowing downward on the panel surface is generated from the convection generating panel 27, and this cool air spreads on the surface of the top plate 51a corresponding to the indirect radiation portion. By being exposed to convection for a long time, the entire top plate 51a is cooled to a temperature corresponding to the convection.

  Thereby, secondary radiant heat exchange occurs also from the whole top plate 51a, and a refreshing feeling can be given to the worker who is working on the work desk 51. Thus, since the secondary radiation from the top plate 51a is used, the individual space 41 can be efficiently cooled. Moreover, since the top plate 51a is cooled, a refreshing feeling due to heat conduction can be given to an operator who touches the top plate 51a.

  In addition, since the convection generating panel 27 also exchanges heat by radiation, a refreshing feeling can be given to the operator by increasing the amount of radiation. And since the radiant heat from the convection generation panel 27 and the top plate 51a does not accompany the airflow, the discomfort caused by the airflow directly hitting the face or the like can also be suppressed.

  The operation during the cooling operation has been described above. During the heating operation, for example, as shown in FIG. 8, the convection generating panel 27 is attached to the panel surface below the top plate 51a. In the example of FIG. 8, the convection generating panel 27 is attached to the lower portion of the front panel 43 by a lower attachment hook 28 </ b> B (lower attachment) provided on the surface of the front panel 43. In this embodiment, since the convection generating panel 27 and the heat medium outlet 24 are connected by the flexible heat medium hoses 25 and 26, the attachment position of the convection generation panel 27 can be easily changed.

  In the example of FIG. 8, warm air of about 26 ° C. is supplied from the floor outlet 14. The convection generating panel 27 is supplied with a heat medium (warm water) heated to a predetermined temperature (around 5 ° C.) higher than the warm air. Thereby, the air warmed by the convection generating panel 27 rises, spreads on the lower surface of the top plate 51a, diffuses and rises around. And the secondary radiant heat from the heated top plate 51a is also added, and the temperature of the individual space 41 is adjusted over a wide range.

  As described above, in the air conditioning system of the present embodiment, the convection generating panel 27 in which the heat medium pipe 27a around which the heat transfer fins 27b are wound is sandwiched between the pair of convection regulating plates 27c is connected to the individual space 41 side in the partition 4. It is attached to the surface. Then, the airflow (convection) generated in the convection generating panel 27 is guided to the top plate 51a of the work desk 51 to adjust the temperature, thereby indirectly radiating heat from the top plate 51a. For this reason, the temperature of the individual space 41 can be adjusted efficiently.

  Further, the upper mounting hook 28A and the lower mounting hook 28B are configured so that one convection generating panel 27 can be attached to the partition surface above the top plate 51a and the partition surface below the top plate 51a. Therefore, one convection generation panel 27 can be shared for cooling and heating by changing the attachment position of the convection generation panel 27 between cooling and heating.

  In addition, since the individual air conditioning unit 2 includes the heat source device 21 that adjusts the temperature of the heat medium independently of the indoor air conditioning unit 1, the overall temperature adjustment by the indoor air conditioning unit 1 and the individual air conditioning unit 2 The temperature adjustment for the individual space 41 can be used in combination, and the temperature of each individual space 41 can be adjusted without wasting energy.

=== Second Embodiment ===
In the first embodiment described above, the convection generating panel 27 in which the heat medium pipe 27a around which the heat transfer fins 27b are wound is sandwiched between the pair of convection regulating plates 27c is used as the convection generating unit. Not. For example, as shown in FIGS. 9 to 11, a heat medium pipe unit 61 in which a heat transfer member is wound around may be used as the convection generating unit.

  As the heat transfer member, for example, the one shown in FIG. 10 can be used. That is, it is possible to use a lattice-like member having a net-like portion 61b in which a wire is knitted into a net shape and wound in a cylindrical shape, and a spoke portion 61c that connects the net-like portion 61b and the heat medium pipe 61a. Further, as shown in FIG. 11, a rectangular coil member 61d may be spirally wound around the heat medium pipe 61a. By comprising in this way, a temperature difference is given also to the surrounding air of a heat-transfer member, and the convection of air can be generated efficiently.

  For example, as shown in FIG. 9, the heat medium pipe unit 61 is attached to the upper end portion of the partition 4 via the upper attachment hook 28A during cooling. Moreover, although illustration is abbreviate | omitted, at the time of heating, it attaches similarly to the partition surface below a top plate 51a.

  Also in the second embodiment, the temperature of the heat medium is transmitted to the air around the heat medium pipe 61a, and convection occurs. As a result, as in the first embodiment, heat can be indirectly radiated through the top plate 51a.

=== Other Embodiments ===
By the way, the present invention is not limited to the above-described embodiment, and various modifications are possible.

  For example, the heat medium may be other than hot water or cold water. Specifically, it may be a refrigerant or a gas such as air. Further, it may be oil.

  In addition, the convection generating portion may be configured by only the heat medium pipe 27a without providing a heat transfer member. By providing the heat transfer member around the heat medium pipe 27a, the heat of the heat medium can be efficiently transmitted to the air around the pipe. Thereby, the surrounding air of a heat-transfer member can be heated or cooled, and a convection can be produced efficiently.

  Further, the attachment for attaching the convection generating portion is not limited to the attachment hook. For example, a magnet or a hook-and-loop fastener may be used. Moreover, the combination of the string for suspension and the latching tool which hangs | hangs this string may be sufficient.

  Further, the indirect radiation unit is not limited to the top plate 51a of the work desk 51, and may be a fixture such as a cabinet 52 or a bookshelf. When the top plate 51a of the work desk 51 is used as in the present embodiment, the temperature adjustment for the space below the top plate 51a, which tends to trap heat, is performed from the top plate 51a during cooling. This can be done efficiently by radiant heat. Further, during heating, the lower body can be effectively warmed for a worker in a seated state. From the viewpoint of heat capacity, the indirect radiation portion is preferably made of a metal material.

  Further, the partition 4 may be other than the partition 4 as long as the individual space 41 can be partitioned.
