Description

  The present invention relates to an air-conditioning chamber having a function of mixing air conditioned by an air conditioner and fresh outside air and blowing out the air.

  As an air conditioning chamber that mixes conditioned air (SA) conditioned in an air conditioner and fresh outside air (OA) and blows it into the room, a cylindrical body (mixing adjusting body) having a large number of openings is provided as an SA inlet in the chamber body. An arrangement is known that is disposed in a transverse state in the vicinity, and the outside air OA is blown out from the cylinder and mixed with the conditioned air SA (see, for example, Patent Document 1).

JP2003-4285A (page 4-8)

  In the air conditioning chamber described in Patent Document 1, since a relatively large mixing adjuster is disposed near the SA entrance in the chamber body, the conditioned air supplied from the air conditioner collides with the mixing adjuster. As a result, the flow is hindered. For this reason, the load (external static pressure) with respect to an air conditioner increases, and the original performance of an air conditioner may not fully be exhibited.

  Further, the structure of the mixing adjuster is relatively complicated, and it is difficult to fix it in the chamber body, so that the assembling work becomes complicated and the cost tends to increase.

  Furthermore, the air conditioning chamber described in Patent Literature 1 is difficult to cope with when the number of branch openings to which the delivery duct is connected increases or decreases. That is, if the number of branch openings increases, the outside air and conditioned air may not be uniformly mixed and distributed, and if the number of branch openings decreases, the conditioned air supplied into the chamber body. In some cases, the resistance of the mixing adjuster becomes too large with respect to the air volume, and the original performance of the air conditioner is not fully exhibited. Further, the mixed air may not be evenly distributed to the plurality of branch openings.

  The problems to be solved by the present invention include a plurality of cases under any operating condition in which a mixture of conditioned air (SA) and fresh outside air (OA) is blown out or only fresh outside air (OA) is blown out. It is an object of the present invention to provide an air conditioning chamber that can distribute air volume evenly to the air outlets, has a low pressure loss, has a simple structure, and is easy to assemble.

The air-conditioning chamber of the present invention has introduced an air conditioning inlet that introduces conditioned air fed from an air conditioner, and an outside air inlet that introduces outside air into the wall of the hollow box-shaped chamber body. In an air conditioning chamber having a plurality of outlets for allowing mixed air of conditioned air and outside air to flow out of the chamber body, a conditioned flow path through which conditioned air introduced from the air conditioning inlet flows into the body chamber And an outside air introduction path disposed at least partially around the air conditioning flow path by the air conditioning flow path and the partition wall, and the partition wall for supplying outside air from the outside air introduction path to the air conditioning flow path An outside air supply port is provided , and outside air guiding means is provided around the outside air supply port for enhancing the mixing of outside air supplied from the outside air supply port with respect to the conditioned air flowing in the air conditioning flow path . It is characterized by that.

  With such a configuration, the outside air introduction path is arranged at least partially around the air conditioning flow path, and the air conditioning flow path and the outside air introduction path are partitioned, so that the air is introduced from the air conditioning inlet. Since there is nothing that hinders the flow of conditioned air, there is little pressure loss and the original performance of the air conditioner is not impaired. Further, a complicated mixing adjustment body is not required, and the assembly work is easy because the structure is a simple structure in which an outside air supply port is provided in a section between the outside air introduction path and the air conditioning flow path.

  Furthermore, when the mixed air of the conditioned air (SA) and fresh outside air (OA) is blown out, the outside air is supplied from the outside air supply port toward the conditioned air flowing through the air conditioning flow path in the chamber body. The conditioned air (SA) and fresh outside air (OA) can be uniformly mixed and distributed evenly to the plurality of outlets. Even when the supply of conditioned air is stopped and only fresh outside air (OA) is blown out, the outside air (OA) can be evenly distributed to the plurality of outlets. That is, even when the mixed air of the conditioned air (SA) and fresh outside air (OA) is blown out, and even when only the fresh outside air (OA) is blown out, it is equal to the plurality of outlets. Air volume distribution can be performed.

  Note that the number of outside air supply ports is not limited, and can be arbitrarily set according to the volume of the chamber body, the number of blow-out ports through which the mixed air flows out of the chamber body, etc. It is desirable to provide a plurality of outside air supply ports in a state of being in the air. Thus, even when a plurality of outside air supply ports are provided, the mixed gas or the outside air can be evenly distributed to each outlet.

Further, by the outside air induction means to enhance the mixing of the outside air supplied from the outside air supply opening is provided in the periphery outside air supply opening for conditioned air flowing through the regulating gas flow passage was induced in the outside air induction means Since the conditioned air and the outside air are sufficiently mixed when the outside air flows into the air conditioning flow path, the uniform mixing of the conditioned air and the outside air is further improved.

  In this case, as an outside air guiding means, an outside air guiding member having an outside air channel that gradually narrows from the outside air supply port toward the air conditioning flow path can be provided around the outside air supply port. If an outside air guiding member having such an outside air flow path is provided, the flow rate of the outside air supplied from the outside air supply port toward the air conditioning flow path is efficiently increased and the stirring action is increased. Can be further improved. As such an outside air guiding member, for example, a substantially truncated cone tubular member, a substantially polygonal truncated cone tubular member and the like are suitable.

  A partition member that divides the opening into a plurality of regions may be provided in a region facing at least the opening of each of the substantially truncated cone tubular member and the substantially polygonal truncated cone tubular member. If such a partition member is provided, it becomes possible to disperse the outside air blown out from the openings of the substantially truncated cone tubular member and the substantially polygonal frustum tubular member in a plurality of directions. The mixing property can be improved.

  On the other hand, a wind direction member that guides the flow direction of the outside air supplied from the outside air supply port as the outside air guiding means in a direction that obliquely merges with the flow direction of the conditioned air flowing in the flow path is provided around the outside air supply port. You can also. If such a wind direction member is provided, the outside air supplied from the outside air supply port can be smoothly merged with the conditioned air flowing through the air conditioning flow path, so that uniform mixing of the conditioned air and the outside air can be achieved. Can be improved.

  Here, as an outside air supply port, it is desirable to provide a slit having a shape opened long along the flow direction of the conditioned air. If such a slit is provided, it becomes possible to continuously supply the outside air from a slit (outside air supply port) located in a long region along the flow direction of the conditioned air, so that the conditioned air and the outside air are uniform. Can be mixed.

  Further, it is desirable that the above-described slit is provided as the outside air supply port, and at least a pair of wind direction plates are opposed to each other with the outside air supply port interposed therebetween and the roof shape is provided with a gap. If such a slit and a wind direction plate are provided, the outside air continuously flowing out from the slit (outside air supply port) located in a long region along the moving direction of the conditioned air passes through the gap of the gradually narrowed wind direction plate. When this occurs, the flow velocity increases and the conditioned air flowing through the air conditioning flow path is blown out vigorously, so that the conditioned air and the outside air can be mixed more uniformly.

  In addition, by changing the inclination angle of the pair of wind direction plates to increase or decrease the gap between the two, the flow rate and flow rate of the outside air blown out from the gap can be adjusted, so it is relatively easy to adjust the outside air suitable for the use situation. The flow rate and flow rate can be set.

  The slit and the wind direction plate described above, for example, form a relatively long I-shaped cut in the partition wall that partitions the outside air introduction path and the air conditioning flow path, and then remove a part of the separated partition wall in the air conditioning flow path direction. Since it can be formed at the same time by bending it, it is easy to manufacture and the structure is simple.

  Here, when the slit and the wind direction plate described above are provided, a drift member that guides the conditioned air flowing in the air conditioning flow path in a direction away from the external air supply port at a position upstream of the external air supply port in the air conditioning flow path. It is desirable to provide it. If such a drift member is provided, the conditioned air flowing through the air conditioning flow path prevents the outside air from flowing out from the outside air supply port, or a part of the conditioned air flowing through the air conditioning flow path is at the outside air supply port. It is possible to prevent the mixed state of the outside air and the conditioned air from deteriorating. As the drift member, a slope plate inclined in a direction away from the outside air supply port is suitable.

  On the other hand, the chamber body is provided with the same number of air inlets as the air outlets, and the air inlets and air outlets have a one-to-one relationship from the air inlet to the air outlet through the air conditioning flow path. It is desirable to provide a partition wall in the chamber body that is partitioned into a plurality of independent regions that communicate with each other. With such a configuration, the region from one air conditioning inlet to one air outlet through the air conditioning flow path is an independent space that does not interfere with each other. For this reason, when using in combination with an air conditioner that can independently turn ON / OFF the conditioned air (SA) to a plurality of air conditioning inlets or adjust the air volume, the air conditioning to each air conditioning inlet The conditioned air or the outside air (OA) can be blown out from each outlet in response to the air (SA) supply condition.

  That is, mixed air in which conditioned air (SA) and fresh outside air (OA) are evenly mixed is blown out from a blowing port communicating with an air conditioning inlet to which conditioned air (SA) is supplied from an air conditioner. In addition, only fresh outside air (OA) can be blown out from the air outlet communicating with the air conditioning inlet where the supply of conditioned air (SA) is stopped. In this way, mixed air of conditioned air (SA) and outside air (OA) is blown out from some of the plurality of outlets, and only outside air (OA) is blown out from the other outlets. Usage is also possible.

  The present invention has the following effects.

(1) In an air conditioning chamber provided with an air conditioning inlet, an outside air inlet, and a plurality of air outlets in the wall of the chamber body, conditioned air introduced from the air conditioning inlet into the body chamber An air conditioning flow path through which the air flows, an outside air introduction path arranged at least partially around the air conditioning flow path by the air conditioning flow path and a partition, and an outside air from the outside air introduction path to the air conditioning flow path By providing an outside air supply port provided in the partition wall for supplying air, there is no obstacle to the flow of conditioned air introduced from the air conditioning inlet, so there is little pressure loss and the air conditioner itself In addition to uniformly mixing conditioned air (SA) and fresh outside air (OA), it is possible to distribute the air volume evenly to multiple outlets with a simple structure. And assembly work To become.

(2) Uniformity of the conditioned air and the outside air is provided by providing an outside air guiding means around the outside air supply port in order to improve the mixing of the outside air supplied from the outside air supply port to the conditioned air flowing in the air conditioning flow path. Mixability can be improved.

(3) If an outside air guiding member having an outside air flow path that gradually narrows from the outside air supply port toward the air conditioning flow path is provided as the outside air guiding means in the vicinity of the outside air supply port, the outside air supply port is directed toward the air conditioning flow path. Since the flow rate of the outside air supplied in this way increases efficiently and the stirring action increases, the uniform mixing of conditioned air and outside air can be further improved.

(4) A wind direction member that guides the flow direction of the outside air supplied from the outside air supply port in a direction that obliquely merges with the flow direction of the conditioned air flowing in the flow path is provided around the outside air supply port as the outside air guiding means. If so, the outside air supplied from the outside air supply port can be smoothly joined to the conditioned air flowing through the air conditioning flow path, so that uniform mixing of the conditioned air and the outside air can be improved.

(5) If a slit having a shape that is long opened along the flow direction of the conditioned air is provided as the outside air supply port, continuous from the slit (outside air supply port) located in a long region along the flow direction of the conditioned air Therefore, it is possible to improve the uniform mixing property between the conditioned air and the outside air.

(6) As an outside air supply port, a slit having a long shape along the flow direction of the conditioned air is provided, and as an outside air guiding member, at least a pair of wind direction plates are opposed to each other with the outside air supply port interposed therebetween, and a gap is provided. If it is arranged in an open roof shape, outside air will blow out from a long area along the moving direction of the conditioned air with respect to the conditioned air flowing in the air conditioning flow path, so that the conditioned air and the outside air are mixed uniformly. Will be able to. Moreover, it becomes possible to set the flow velocity and flow rate suitable for the use situation relatively easily.

(7) When the slit and the wind direction plate are provided, a drift member for guiding the conditioned air flowing in the air conditioning flow path in a direction away from the external air supply port is provided upstream of the external air supply port in the air conditioning flow path. For example, the conditioned air flowing through the conditioned flow path prevents the outside air from flowing out from the outside air supply port, or a part of the conditioned air flows into the outside air supply port, which deteriorates the mixing state of the outside air and the conditioned air. Can be prevented.

(8) The chamber body is provided with the same number of air inlets as the air outlets, and the air inlet and air outlets are paired in the region from the air inlet to the air outlet through the air conditioning flow path. If partition walls that are partitioned into a plurality of independent areas that communicate with each other in the relationship of 1 are provided in the chamber body, the supply of conditioned air to each air conditioning inlet can be independently turned ON / OFF, or the air volume can be adjusted. When used in combination with an air conditioner, the mixed air or the outside air can be blown out from the respective outlets in an appropriate manner corresponding to the supply status of the conditioned air to the air conditioning inlets.

  Hereinafter, an air conditioning chamber according to an embodiment of the present invention will be described with reference to the drawings. 1 is a plan view showing an air conditioning chamber according to an embodiment of the present invention, FIG. 2 is a partially cutaway plan view of the air conditioning chamber shown in FIG. 1, and FIG. 3 is a line AA in FIG. 4 is a sectional view taken along line BB in FIG. 3, and FIG. 5 is a sectional view taken along line CC in FIG.

  As shown in FIG. 1, in the air conditioning chamber 1 of the present embodiment, a rectangular wall 4 is passed from an air conditioner (not shown) to a back wall portion 3 of a hollow box-shaped chamber body 2 having a rectangular parallelepiped shape. In order to introduce the conditioned air SA to be fed, an air conditioning inlet 5 having a rectangular cross section is provided and fed to the side wall portion 6 of the chamber body 2 via the circular duct 7. In order to introduce the outside air OA, a circular outside air introduction port 8 is provided, and mixed air MA of the introduced conditioned air SA and outside air OA is introduced into the side wall portions 6 and 9 and the front wall portion 10 of the chamber body 2. A total of six circular outlets 11 are provided to flow out of the chamber body 2.

  One outlet 11 is provided for each of the side wall bodies 6 and 9, and four outlets 11 are provided in the front wall body 10 at regular intervals. A flexible duct 12 is connected to each of these outlets 11, and each flexible duct 12 is piped to a living room space (not shown) to be air-conditioned.

  As shown in FIGS. 2 to 5, the main body chamber 2 is provided with an air conditioning flow path 13 through which the conditioned air SA introduced from the air conditioning introduction port 5 flows. An outside air introduction path 14 partitioned by the partition wall 2 a is disposed in a lower part of the part, and five outside air supply ports for supplying the outside air OA introduced into the outside air introduction path 14 to the conditioned flow path 13. 15 is provided in the partition 2a.

  The outside air introduction path 14 is disposed along the back wall body portion 3 and the bottom wall body portion 16 in the main body chamber 2, and has a rectangular funnel portion at a portion facing the outside air introduction port 8 and a portion facing the side wall body portion 9. It is formed in a square tube shape having 14a and 14b. By providing such square funnel portions 14a and 14b, resistance to the outside air supplied from the circular duct 7 can be reduced. In the present embodiment, the blowout ports 11 are provided in the side wall portions 6 and 9 on both sides of the main body chamber 2, but by providing the square funnel portions 14 a and 14 b, air is supplied to the left and right blowout ports 11. Can be evenly distributed. Further, the outside air inlet 8 and the circular duct can be provided on either of the side wall bodies 6 and 9 of the main body chamber 2.

  The outside air supply port 15 is formed in a long slit shape along the flow direction 17 of the conditioned air SA in the air conditioning flow path 13, and a pair of wind direction plates 18 stand so as to face each other with the outside air supply port 15 interposed therebetween. These wind direction plates 18 are arranged in a roof shape with a gap 19.

  In the air conditioning chamber 1, since the outside air introduction path 14 is partitioned and arranged by the partition wall 2 a below the air conditioning flow path 13, the conditioned air SA introduced into the chamber body 2 from the air conditioning inlet 5. There is nothing that prevents flow. For this reason, there is little pressure loss, it does not impair the original performance of the air conditioner, the conditioned air (SA) and the fresh outside air (OA) are uniformly mixed, and the mixed air is supplied to the plurality of outlets 11. It can be distributed with an even air volume. The air conditioning chamber 1 has a simple structure and can be easily assembled.

  In the air conditioning chamber 1, as shown in FIGS. 2 and 6, since the outside air OA is supplied from the outside air supply port 15 to the conditioned air SA flowing through the air conditioning flow path 13, the conditioned air SA and fresh outside air are supplied. OA can be mixed uniformly. For this reason, it is not necessary to secure a wide mixing space for mixing the conditioned air SA and the outside air OA in the chamber body 2, and it is possible to avoid an increase in the size of the air conditioning chamber.

  Furthermore, since the slit-shaped outside air supply port 15 that is long opened along the flow direction 17 of the conditioned air SA is provided, the outside air OA is continuously drawn from a relatively long region along the movement direction 17 of the conditioned air SA. It is possible to supply, and thereby the uniform mixing property of the conditioned air SA and the outside air OA can be improved.

  Further, as described above, as an outside air guiding member for increasing the flow rate of the outside air OA supplied from the outside air supply port 15 toward the air conditioning flow path 13, a pair of the outside air supply ports 15 are opposed to each other as described above. Wind direction plates 18 are erected, and these wind direction plates 18 are arranged in a roof shape with a gap 19. Therefore, the outside air OA flowing out of the outside air supply port 15 passes through the gap 19 of the wind direction plate 18 that is gradually narrowed, and the flow velocity thereof increases. It begins to blow out vigorously.

  For this reason, the outside air OA reaches a region away from the outside air supply port 15 in the chamber main body 2, and a strong agitating action on the conditioned air SA flowing through the air conditioning flow path 13 is also generated. And the uniform mixing property of the outside air OA are greatly improved.

  In this case, if the inclination angle of the pair of wind direction plates 18 is changed to increase / decrease the gap 19 between them, the flow rate and flow rate of the outside air OA blown out from the gap 19 can be adjusted. The flow rate and flow rate can be set appropriately. In the present embodiment, among the five outside air supply ports 15, the inclination angle of the wind direction plate 18 of each of the two outside air supply ports 15 located at both ends is set to 40 degrees, and the three outside air supply ports located in the center portion. The inclination angle of the 15 wind direction plates 18 is 45 degrees. As described above, when the gap 19 between the two pairs of wind direction plates 18 located at both ends is made smaller than the gap 19 between the other three pairs of wind direction plates 18, the amount of outside air from the two outside air supply ports 15 located at both ends. The mixed air formed in the chamber body 2 could be distributed to the six outlets 11 with an equal air volume.

  The slit-shaped outside air supply port 15 and the wind direction plate 18 are formed by forming a relatively long I-shaped cut in the partition wall 2a that partitions the outside air introduction path 14 and the air conditioning flow path 13 and then separating the partition walls. Since a part (the part that becomes the wind direction plate 18) can be formed simultaneously by bending in the direction of the air conditioning flow path 13, the manufacture is easy and the structure is simple.

  On the other hand, as shown in FIG. 7, in the air conditioning chamber 1 of the present embodiment, the conditioned air SA flowing in the conditioned flow passage 13 is supplied to the outside air supply port upstream of the outside air supply port 15 in the conditioned flow passage 13. An inclined plate 20 is provided as a drift member that guides in a direction away from 15. Since the inclined plate 20 is inclined in a direction away from the outside air supply port 15, a part of the conditioned air SA flowing in the air conditioning flow path 13 is guided in a direction away from the outside air supply port 15. Therefore, the conditioned air SA does not flow into the wind direction plate 18 from the triangular area 15a at the end face portion of the opposing wind direction plate 18 to prevent the outside air OA from flowing out, and the mixed state of the outside air OA and the conditioned air SA. Troubles that adversely affect the system can be avoided.

  In the air conditioning chamber 1 of the present embodiment, it is possible to stop the supply of the conditioned air SA and blow out only the outside air OA from each outlet 11. Even in this case, the outside air OA can be evenly distributed and blown out to the respective outlets 11.

  Next, based on FIGS. 8-11, the air-conditioning chamber 21 which is 2nd Embodiment of this invention is demonstrated. In addition, in the constituent parts of the air conditioning chamber 21 shown in FIGS. 8 to 11, the same reference numerals as those in FIGS. 1 to 7 are given to parts that exhibit the same functions and effects as the constituent parts of the air conditioning chamber 1 described above. The description is omitted.

  As shown in FIG. 8, in the air conditioning chamber 21 of the present embodiment, four ducts 24 are provided from a distribution type air conditioner 36 to a back wall portion 23 of a chamber body 22 having a rectangular parallelepiped shape and a hollow box shape. Four air conditioning inlets 25 are provided to introduce the conditioned air SA fed via the external air OA fed via the duct 27 to the side wall portion 26 of the chamber body 22. A circular outside air inlet 28 is provided for introduction.

  In addition, a total of four circular outlets 31 are provided in the front wall portion 29 of the chamber body 22 in order to flow the mixed air MA of the introduced conditioned air SA and the outside air OA out of the chamber body 22. Yes. Each of the four ducts 24 is connected to four air conditioning inlets 25, and in the chamber body 22, blowout ports 31 are arranged at positions facing these air conditioning inlets 25, respectively.

  Further, as shown in FIGS. 9 to 11, in the main body chamber 22, four air conditioning flow paths 33 through which the conditioned air SA introduced from the air conditioning introduction port 25 flows are partitioned by three partition walls 32. It is formed in a state. That is, the area from each air conditioning inlet 25 to the air outlet 31 via the air conditioning flow path 33 is divided into four independent areas by the number of the air conditioning inlets 25 by the three partition walls 32. It is partitioned.

  In addition, the outside air introduction path 34 is arranged below the air conditioning flow paths 33 by partitioning with the partition walls 22a, so that the outside air introduction path 34 is disposed in the lower part of the air conditioning flow paths 33, and the outside air OA introduced into the outside air introduction path 34. Are supplied to the air conditioning flow path 13 in the partition wall 22a. The outside air supply ports 35 open one by one toward the four air conditioning flow paths 33.

  As described above, in the air conditioning chamber 21 of the present embodiment, the four air conditioning flow paths 33 partitioned by the partition walls 32 for each of the four air conditioning inlets 25 are formed in the chamber body 22, respectively. The outside air OA is supplied from the outside air supply port 35 toward the air conditioning flow path 33. In addition, the conditioned air supplied from the distribution type air conditioner 36 to the air conditioning inlet 25 via the four ducts 24 is turned ON / OFF independently for each outlet 31 and the air volume is adjusted. You can do it.

  In the air conditioning chamber 21, the four air conditioning flow paths 33 are formed in the chamber main body 22, so that the four air conditioning inlets 25 through the air conditioning flow paths 33 to the outlet 31 are provided. The region is an independent space in which the air conditioning inlet 25 and the outlet 31 communicate with each other in a one-to-one relationship. For this reason, when the air-conditioning chamber 21 is used in combination with the air conditioner 36, the mixed air MA or the outside air OA can be output from the respective outlets 31 in an appropriate manner corresponding to the supply state of the conditioned air to the air conditioning introduction ports 25. Can be blown out.

  That is, the mixed air MA in which the conditioned air SA and the fresh outside air OA are evenly mixed is blown out from the outlet 31 communicating with the air conditioning inlet 25 to which the conditioned air SA is supplied from the air conditioner 36. In addition, only fresh outside air OA can be blown out from the air outlet 31 communicating with the air conditioning inlet 25 where the supply of the conditioned air SA is stopped.

  Therefore, it is also possible to use such a method that the mixed air MA of the conditioned air SA and the outside air OA is blown out from some of the four blowing openings 31, and only the outside air OA is blown out from the other blowing openings 31. For this reason, the air-conditioning chamber 21 can be suitably employed as a component of air-conditioning equipment such as a hospital equipped with a four-bed hospital room.

  Further, in the air conditioning chamber 21, as in the air conditioning chamber 1 described above, since the outside air introduction path 34 partitioned by the partition wall 22 a is arranged in the lower part of each air conditioning flow path 33, the air conditioning inlet There is nothing that hinders the flow of conditioned air SA introduced from 25 into the chamber body 22. For this reason, the pressure loss of the conditioned air SA in the chamber body 22 is small, and the original performance of the air conditioner is not impaired.

  Further, since the outside air OA is supplied from the outside air supply port 35 to the conditioned air SA flowing through the four air conditioning flow paths 33, the conditioned air SA and the fresh outside air OA can be uniformly mixed. For this reason, it is not necessary to secure a wide mixing space for mixing the conditioned air SA and the outside air OA in the chamber body 22, and it is possible to avoid an increase in the size of the air conditioning chamber. Other functions and effects are the same as those of the air conditioning chamber 1 described above.

  Next, with reference to FIGS. 12A to 12D, other embodiments relating to the outside air guiding member will be described. 12A to 12D are partially cutaway perspective views showing other embodiments of the outside air guiding member.

  The outside air guiding member shown in FIG. 12 (a) is a substantially truncated cone cylindrical member 40, and FIG. 12 (b) is a substantially quadrangular pyramid tubular member 45. Each of the outside air guiding members is adjusted from the outside air supply port. Outside air flow paths 41 and 46 that gradually narrow toward the air flow path are provided. If such a substantially truncated cone tubular member 40 and a substantially quadrangular pyramid tubular member 45 are provided, the flow rate of the outside air supplied from the outside air introduction path 49 to the conditioned flow path via the outside air supply port can be reduced. Since it can increase efficiently, the stirring effect | action of the external air with respect to conditioned air increases, and the uniform mixing property of conditioned air and external air can further be improved.

  On the other hand, in the substantially quadrangular frustum cylindrical members 42 and 47 shown in FIGS. 12C and 12D, the openings 42a and 47a are divided into a plurality of areas in the areas facing the openings 42a and 47a, respectively. Partition members 43 and 48 having a substantially V-shaped cross section are provided. If such partition members 43 and 48 are provided, the outside air blown out from the openings 42a and 47a of these substantially square frustum cylindrical members 42 and 47 can be dispersed in a plurality of directions. The agitation action is enhanced, and the uniform mixing of conditioned air and outside air is greatly improved.

  In addition, although the cross-sectional shape of the partition members 43 and 48 is substantially V-shaped, the cross-sectional shape may be rectangular or elliptical because the shape is not limited to this. When a partition member having a rectangular or elliptical cross section is used, it exerts a rectifying action that regulates the flow of outside air, so that the outside air that has passed through the outside air channels 41 and 46 can be reliably blown upward.

  Next, based on FIGS. 13-15, the air-conditioning chamber which is 3rd Embodiment of this invention is demonstrated. 13 is a partially cutaway plan view showing an air conditioning chamber according to a third embodiment of the present invention, FIG. 14 is a sectional view taken along line EE in FIG. 13, and FIG. 15 is a line FF in FIG. It is sectional drawing. In addition, in the components of the air-conditioning chamber shown in FIGS. 13 to 15, the same reference numerals as those in FIGS. Description is omitted.

  As shown in FIGS. 13 to 14, in the air conditioning chamber 50, an outside air supply port 51 which is long opened along the flow direction 17 of the conditioned air SA is directed from the air conditioning inlet 5 side into the chamber body 2. A wind direction member 52 having a triangular roof shape is disposed so as to cover it. The air direction member 52 has a shape that forms an upward gradient from the air conditioning inlet 5 side into the chamber body 2, and a portion of the outside air inlet 51 near the outlet 11 is open.

  Therefore, as shown in FIG. 14, the outside air OA flowing out from the outside air supply port 51 abuts on the lower surface of the wind direction member 52 and flows through the air conditioning flow path 13 after the wind direction is guided toward the blowout port 11. The conditioned air SA is blown out in a direction in which the conditioned air SA flows obliquely. For this reason, the outside air OA supplied from the outside air supply port 51 can be smoothly joined to the conditioned air SA flowing through the air conditioning flow path 13, and the conditioned air SA and the outside air OA can be mixed uniformly. it can.

  Further, by providing the wind direction member 52, it is possible to prevent the backflow of the outside air OA to the air conditioner side, and the flow of the conditioned air SA does not prevent the outside air OA from flowing out from the outside air supply port 51. Furthermore, by providing the wind direction member 52, the pressure loss is reduced, so the burden on the air conditioner that supplies the conditioned air SA can be reduced. Such a wind direction member 52 can also be attached to the portion of the outside air supply port 35 of the air conditioning chamber 21 shown in FIGS. 8 to 11, and the same effect as described above can be obtained.

  In the present embodiment, the wind direction member 52 has a triangular roof shape, but is not limited to this, and the function of guiding the outside air OA blown out from the outside air supply port 51 obliquely without disturbing the flow of the conditioned air SA. If it is the shape which has, it can also be set as a smooth curved surface shape, a wedge shape, etc.

  Next, with reference to FIG. 16, the air-conditioning chamber which is 4th Embodiment of this invention is demonstrated. FIG. 16 is a cross-sectional view showing an air conditioning chamber according to the fourth embodiment of the present invention, and corresponds to FIG. 10 showing a cross section of the air conditioning chamber 21 of the second embodiment. In the components of the air conditioning chamber shown in FIG. 16, the same reference numerals as those in FIGS. 1 to 11 are given to the portions that exhibit the same functions and effects as the components of the air conditioning chambers 1 and 21 described above. Omitted.

  As shown in FIG. 16, in the air conditioning chamber 60 of the present embodiment, the outside air supply port 61 is provided not obliquely below the virtual axis 31 a of the blowout port 31 but obliquely below the virtual axis 31 a. The structure of other parts is the same as that of the air conditioning chamber 21. If the outside air supply port 61 is provided at such a position, the outside air OA blown out from the outside air supply port 61 via the gap 19 flows into the conditioned flow paths 33 from the air conditioner (not shown). Direct hitting of the SA flow can be avoided.

  Therefore, the outside air OA blown out from the outside air supply port 61 through the gap 19 and the conditioned air SA flowing into each of the air conditioning flow paths 33 do not interfere with each other, and the pressure in the air conditioning flow path 33 Loss can be reduced. Further, by eliminating such mutual interference, it is possible to blow out a certain amount of outside air OA from the outside air supply port 61 without being affected by whether or not the conditioned air SA is supplied into the respective air conditioning flow paths 33. Become. For this reason, even when supply of the conditioned air SA is stopped in any one of the air conditioning flow paths 33, the outside air OA blown out to each air conditioning flow path 33 can be maintained at a constant amount.

  The air-conditioning chamber of the present invention can be widely used as a component of air-conditioning equipment for various buildings such as office buildings, factory buildings, and hospitals.
