JP 2011-106757 A

  However, in the airflow generation device described in Patent Document 1, since the airflow rectifier is fixedly installed on the downstream side of the blower, the rectification of the airflow blown out from the airflow rectifier (the uniformity of the wind speed and the It is considered that the downward airflow cannot be directed in a desired direction while the straightness is improved. For this reason, when this airflow generation device is installed in a refrigerator compartment that thermally divides a plurality of article storage areas without using a partition wall, an optimum circulation flow for individually maintaining the temperature of each article storage area There is a problem that it is difficult to produce.

  The present invention has been made to solve the above-described problems, and one object of the present invention is to individually control the temperatures of a plurality of article storage areas that are thermally divided from each other without using a partition wall. It is to provide a refrigerated warehouse capable of forming an optimal circulation flow to maintain.

  In order to achieve the above object, a refrigerated warehouse according to one aspect of the present invention has a first article storage area maintained at a first temperature and a second article storage area maintained at a second temperature separated from each other by a partition wall. The first air curtain device installed on the first article storage area side in order to thermally divide the refrigeration room into a first article storage area and a second article storage area. And at least one of the first air curtain device and the second air curtain device, each of which has a blowing function, rectifies the blown air and rectifies The movable rectification member comprised so that adjustment of the wind direction of the blowing air which was made is included.

As a result, the air blown from at least one of the first air curtain device or the second air curtain device is directed in a desired direction in a state where air flow rectification (uniformity of wind speed and straightness) is improved by the movable rectifying member. Is blown out. Therefore, even when the first air curtain device and the second air curtain device are installed in the refrigerator compartment and the first article storage area and the second article storage area are thermally divided from each other without using a partition wall, Can be directed in a desired direction, so that an optimum circulation flow for maintaining the temperature of each article storage region individually can be formed.

  In the refrigerated warehouse according to the above aspect, preferably, at least one of the first air curtain device or the second air curtain device suppresses the leakage of the blown air from a portion other than the movable rectifying member, and rectifies the blown air. A windshield member for guiding the member is further included. If comprised in this way, even if the movable rectification member which can adjust the wind direction of blowing air is provided, it will suppress that the blowing air leaks from parts other than a movable rectification member by a wind-shielding member at the time of wind direction adjustment of blowing air be able to. Thereby, the turbulence of the air curtain airflow around the movable rectifying member can be suppressed, and a shortage of air volume can be suppressed in the air curtain airflow blown from the movable rectifying member. As a result, it is possible to reliably obtain the heat insulation function and heat insulation effect of the air curtain airflow that thermally divides the first article storage area and the second article storage area while forming an optimal circulation flow.

  In the refrigerated warehouse according to the above aspect, the first air curtain device and the second air curtain device are preferably arranged adjacent to each other along the boundary between the first article storage area and the second article storage area. In addition, the air flow direction of the rectified blown air is adjusted by the movable rectifying member so that the air curtain air flow blown from each of the first air curtain device and the second air curtain device increases the separation distance from each other. Has been. If comprised in this way, since the air curtain air current which blows off from each of a 1st air curtain apparatus and a 2nd air curtain apparatus is prevented from colliding with each other, in order to maintain a 1st article preservation | save area | region at 1st temperature.

It is configured. According to this configuration, regardless of how the first temperature and the second temperature are set, the wind direction of the blown air rectified by the movable rectifying member is changed between the first air curtain device and the second air curtain device. Since it is adjusted individually, the shape of the air curtain airflow is distorted (curved) near the boundary between the first article storage area and the second article storage area due to the temperature difference between the first temperature and the second temperature. Can be suppressed. Therefore, it is possible to easily maintain the first temperature on the first article storage area side and the second temperature on the second article storage area side even near the boundary between the first article storage area and the second article storage area. it can.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below with reference to the drawings.

[First Embodiment]
(Structure of refrigerated warehouse)
With reference to FIGS. 1-6, the refrigerated warehouse 100 by 1st Embodiment of this invention is demonstrated.

  As shown in FIG. 1, the refrigerated warehouse 100 includes a refrigerated room 10 having an internal space 10a. Further, in the internal space 10a, an area 11 for storing the article 1 in a frozen state at a temperature T1 and an area 12 for storing the article 2 in a refrigerator at a temperature T2 different from the article 1 (T2> T1 in this case) are provided. Yes. The temperatures T1 and T2 are examples of the “first temperature” and the “second temperature” in the present invention, respectively. Areas 11 and 12 are examples of the “first article storage area” and the “second article storage area” of the present invention, respectively.

  The internal space 10a is not provided with a partition that physically partitions the region 11 on the X1 side and the region 12 on the X2 side. In this case, the inside of the refrigerator compartment 10 is configured such that cold air is circulated so as to maintain the region 11 at the temperature T1 and the region 12 at the temperature T2. Thereby, the area | region 11 and the area | region 12 are thermally divided | segmented into temperature T1 and T2 without using a partition. Therefore, an operator (not shown) is configured to be able to work on the article 1 or 2 by going (passing) between the area 11 and the area 12.

  In the refrigerator compartment 10, air curtain devices 20 and 40 each having a blowing function are installed below the ceiling portion 13. The air curtain devices 20 and 40 are arranged adjacent to each other along a boundary region 10b (region in a two-dot chain line) between the region 11 and the region 12. Further, the air curtain devices 20 and 40 have substantially the same device configuration, and the air curtain device 40 is installed facing the air curtain device 20 in the opposite direction. Air curtain devices 20 and 40 each have a role of forming airflows P1 and P2 that reach the vicinity of floor 14 respectively. As a result, the airflows P1 and P2 both reach the vicinity of the floor 14 in the boundary region 10b, so that the heat transfer between the region 11 and the region 12 along the general X direction is blocked. Airflows P1 and P2 are examples of the “air curtain airflow” of the present invention.

  A rail member 91 extending in the X direction is attached to the lower surface 13 a of the ceiling portion 13, and a pedestal 92 described later is movable along the rail member 91. The air curtain devices 20 and 40 are installed on the X1 side and the X2 side of the lower surface 92b of the gantry 92, respectively. In the refrigerator compartment 10, even when the contents and the number of the articles 1 and 2 change with the seasonal change, the volume ratio of the areas 11 and 12 (the position of the boundary area 10b) is changed by moving the gantry 92 in the X direction. It is configured to be possible.

  In the regions 11 and 12, cooling devices 30 and 50 each having a blowing and cooling function are installed. The cooling device 30 is installed on the upstream side (X1 side) of the circulating flow G1 from the suction port 21 of the air curtain device 20, and the cooling device 50 is connected to the circulating flow G2 more than the suction port 41 of the air curtain device 40. It is installed on the upstream side (X2 side).

  As shown in FIG. 2, the refrigerated warehouse 100 includes a controller device 70. The controller device 70 includes an overall control unit 71, an air curtain device control unit 72, and a cooling device control unit 73. The air curtain device control unit 72 is responsible for operation control of the air curtain devices 20 and 40, and the cooling device control unit 73 is responsible for operation control of the cooling devices 30 and 50. Further, temperature sensors 81 and 82 for detecting the temperatures of the regions 11 and 12, respectively, and a temperature sensor 83 for detecting the temperature in the vicinity of the floor surface 14 in the boundary region 10b are provided in the refrigerator compartment 10, respectively. Are electrically connected to the overall control unit 71. Then, the control of the air curtain devices 20 and 40 and the control of the cooling devices 30 and 50 are performed based on the command of the overall control unit 71, whereby the cool air circulation flows G1 and G2 that thermally divide the inside of the refrigerator compartment 10 are performed. (See FIG. 1) are formed in regions 11 and 12, respectively.

  Here, the circulation flows G1 and G2 will be described. As shown in FIG. 1, the cold air blown from the air outlet 32 of the cooling device 30 is sucked into the air inlet 21 of the air curtain device 20 along the lower surface 13 a of the ceiling portion 13 in the direction of the arrow X2. The cool air is blown downward from the air outlet 22 of the air curtain device 20 as an air flow P1. After the airflow P1 reaches the floor surface 14, most of the airflow P1 is circulated along the direction of the arrow X1 along the direction of the arrow X1 and is sucked into the suction port 31 of the cooling device 30 through the vicinity of the side wall portion 15a on the X1 side. As a result, a circulating flow G1 that circulates greatly in the clockwise direction is formed in the region 11. A part of the airflow P1 that has reached the floor surface 14 also changes its direction in the direction of the arrow X2, rises in the boundary region 10b, and is mixed with the cold air from the air outlet 22 again. Accordingly, a counterclockwise vortex flow Q1 is simultaneously formed in the boundary region 10b. Further, the circulating air flow G2 in the region 12 is opposite to the circulating air flow G1. At this time, a part of the airflow P2 reaching the floor surface 14 rises in the boundary region 10b and is mixed with the cold air from the outlet 42 again. That is, a clockwise vortex Q2 is simultaneously formed in the boundary region 10b.

  Here, in 1st Embodiment, it is comprised so that the wind speed and wind direction of the airflow P1 which blow off from the air curtain apparatus 20 and the wind speed and wind direction of the airflow P2 which blow off from the air curtain apparatus 40 may be adjusted separately. Has been. More specifically, the air curtain device 20 is provided with a rectifying mechanism portion 23 that can be rotated outside (below) the air outlet 22. Further, the air curtain device 40 is similarly provided with a rectifying mechanism portion 23 that can be rotated outside (downward) from the air outlet 42. Below, the structure of these rectification | straightening mechanism parts 23 is demonstrated.

(Structure of rectifying mechanism)
As shown in FIG. 3, the rectifying mechanism 23 includes a movable rectifying member 24, a fixing member 25 for fixing the movable rectifying member 24, and the movable rectifying member 24 rotated in the arrow R1 direction or the arrow R2 direction about the Y axis. The rotation part 26 to be moved, and the expansion / contraction member 27 that connects the end part 25a opposite to the rotation part 26 of the fixing member 25 (X2 side) and the lower surface 20a in the vicinity of the air outlet 22 are included. The stretchable member 27 is an example of the “wind shield member” in the present invention.

  The movable rectifying member 24 has a honeycomb structure in which a plurality of through-holes 24a for ventilation having a regular hexagonal column shape are arranged adjacent to each other with almost no gap. The fixing member 25 has a structure in which a mesh wire mesh is stretched on a fixed frame that fixes the movable rectifying member 24. The rotating unit 26 includes a rotating shaft 26a and a fixed unit 26b. In the rotating unit 26, the rotating shaft 26a is driven by a motor (not shown) based on a command from the air curtain device control unit 72 (see FIG. 2). ). The stretchable member 27 has a bellows structure that can be stretched. Further, the telescopic member 27 has one end portion 27a fixed to the end portion 25a of the fixing member 25 and the other end portion 27b fixed to the lower surface 20a.

  Further, the movable rectifying member 24, the fixing member 25, the rotating portion 26, and the telescopic member 27 are provided on the Y1 side (the front side of the paper) of the air outlet 22 while maintaining the cross-sectional shape (space S) shown in FIG. It extends from the end to the end on the Y2 side (the back side of the drawing). Moreover, as shown in FIG. 5, the side plate member 28 which covers the both ends of the Y direction of the movable rectification member 24 is attached to the lower surface 20a. The side plate member 28 extends downward from the lower surface 20a. Moreover, the rotation part 26, the expansion-contraction member 27, and the side-plate member 28 each consist of material which has airtightness (it does not have air permeability). In addition, an air sealant (not shown) is applied to the attachment portions of the rotating portion 26, the expansion and contraction member 27, and the side plate member 28 to the lower surface 20a. The side plate member 28 is an example of the “wind shield member” in the present invention.

  Thereby, in 1st Embodiment, the air which blown off from the blower outlet 22 in the air curtain apparatus 20 was rectified | rectified by the movable rectification | straightening member 24 when passing the rectification | straightening mechanism part 23, and was directed to the predetermined | prescribed direction. It is configured to be blown out as an air flow P1. In addition, that air is rectified means that the uniformity and straightness of the wind speed of the passing air passing through the rectifying mechanism 23 are improved. Further, as shown in FIG. 1, the predetermined direction is an air flow P <b> 1 in a state where the movable rectifying member 24 is rotated toward the region 11 by an angle α with respect to the vertical direction (Z direction) and rectified in this direction. It means the direction (wind direction) that is blown out.

  Therefore, as shown in FIG. 3, when the movable rectifying member 24 is not rotated (angle α = 0 degree), the plurality of through holes 24a are directed directly downward (in the direction of arrow Z2), so that the airflow P1 is blown directly downward. The On the other hand, as shown in FIG. 4, in the state where the rotating shaft 26a is rotated in the direction of the arrow R2 and the movable rectifying member 24 is rotated by the angle α, the plurality of through holes 24a are directed obliquely downward. The airflow P1 in the rectified state is tilted toward the region 11 by the angle α and blown out.

  Further, in a state where the movable rectifying member 24 shown in FIG. 3 is not rotated, a space S surrounded by the rotating portion 26, the expansion / contraction member 27, and the side plate member 28 is formed below the air outlet 22. It is configured. In addition, the height dimension (Z direction) of the fixing | fixed part 26b is adjusted beforehand so that the whole rectification | straightening mechanism part 23 may be attached horizontally to the lower surface 20a of the air curtain apparatus 20 in the state which the expansion-contraction member 27 contracted. The space S is an example of the “air passage” in the present invention.

  In the first embodiment, not only the state where the movable rectifying member 24 is not rotated but also the state where the movable rectifying member 24 shown in FIG. The space S to the entrance surface 24b is deformed from a rectangular shape (see FIG. 3) so as to have a fan-shaped cross section around the rotation shaft 26a. At this time, as shown in FIG. 4, the expansion / contraction member 27 is expanded (expanded / contracted) according to the rotation amount of the movable rectifying member 24. Thus, the air blown from the outlet 22 is prevented from leaking outside from the portion other than the movable rectifying member 24 in the space S, and almost all of the blown air is transferred to the movable rectifying member 24 via the fixing member 25. It is configured to be guided.

  As shown in FIG. 1, the air curtain device 40 is similarly provided with a rectifying mechanism 23. As a result, the air blown out from the air outlet 42 in the air curtain device 40 is blown out as an air flow P2 directed in a predetermined direction while being rectified by the movable rectifying member 24 when passing through the rectifying mechanism portion 23. Is done. In this case, the rectified airflow P2 is blown out in a direction inclined by an angle β with respect to the vertical direction (Z direction).

  Further, in the first embodiment, the wind directions (angles α and β) of the rectified blown air are individually adjusted by the movable rectifying members 24 on the air curtain device 20 side and the air curtain device 40 side. It is configured. That is, the angle α and the angle β are adjusted individually.

  Specifically, calculation processing is performed by the overall control unit 71 (see FIG. 2) based on the detected value of the internal temperature by the temperature sensors 81 and 82, and the air volume control of each of the air curtain devices 20 and 40 is performed. Then, the rotation angle control of the rectifying mechanisms 23 and 43 is performed. Thus, the region 11 is adjusted so as to be maintained at the temperature T1 and the region 12 at the temperature T2. In particular, when the difference between the temperatures T1 and T2 is large, this control works effectively, and the temperature maintenance management of the regions 11 and 12 is appropriately achieved.

  As an example, the temperature of the circulating flow G1 sucked into the cooling device 30 by the temperature sensor 81 is detected as 0 degrees Celsius, and the temperature of the circulating flow G2 sucked into the cooling device 50 by the temperature sensor 82 is detected as 10 degrees Celsius, Assume that the sensor 83 detects the temperature near the floor surface 14 in the boundary region 10b in a state of 2 degrees Celsius. In this case, as shown in FIG. 1, the vortex flow Q1 that collides with the floor surface 14 and reaches the temperature sensor 83 as the relatively cool airflow P1 collides with the floor surface 14, and the temperature sensor The overall control unit 71 (see FIG. 2) determines that there are more states than the eddy current Q2 that reaches 83.

  Then, based on the current wind speed V1 and wind direction (angle α) of the airflow P1 and the current wind speed V2 and wind direction (angle β) of the airflow P2, the wind speed V1 is decreased and the angle α is increased (inclined from the vertical direction). Control to increase the angle) alone, or control to increase the wind speed V2 and decrease the angle β (making the tilt angle closer to the vertical direction), or perform these two controls simultaneously. It is determined by the overall control unit 71 (see FIG. 2) whether to do this.

  By adjusting the wind speed and direction of the air flow P1 and / or the air flow P2 by the above method, the air volume forming the vortex Q1 is gradually reduced, and the air volume forming the vortex Q2 is gradually increased. Accordingly, the temperature in the vicinity of the floor 14 in the boundary region 10b is gradually increased from the previous 2 degrees Celsius toward an intermediate temperature between the temperature T1 (about 0 degrees) and the temperature T2 (about 10 degrees). . Even in the case where a significant temperature difference is generated between the temperatures T1 and T2 by making the shapes of the airflows P1 and P2 asymmetric as in this example, the temperature difference between the temperatures T1 and T2 (about 10%). Therefore, the cold air in the region 11 and the cold air in the region 12 are not easily mixed. Further, by providing a difference in wind speed and angle between the airflows P1 and P2 rectified by the movable rectifying member 24, the airflows P1 and P2 are sucked and merged to form one downdraft in the boundary region 10b. It is configured so as to be prevented.

  Thus, in the first embodiment, the airflows P1 and P2 rectified by the movable rectifying member 24 and blown out from each of the air curtain devices 20 and 40 increase the separation distance M (see FIG. 1) in the X direction. Further, the air flow direction (angles α and β) of the rectified blown air is adjusted by the movable rectifying member 24. And the circulation flow G1 (vortex flow Q1) and the circulation flow G2 (vortex flow Q2) according to the preset temperature in the refrigerator compartment 10 are formed, so that the temperature unevenness in the region 11 and the region 12 is minimized. Control configured. Thereby, energy saving as the refrigerated warehouse 100 is achieved.

(Structure of slide mechanism)
Further, the air curtain devices 20 and 40 are fixed to the lower surface 92b side of the gantry 92 with a separation interval corresponding to the width (X direction) of the boundary region 10b. A pulley section 93 is provided on the upper surface 92 a of the gantry 92. And the some wheel 94 in the pulley part 93 is engaged with the rail member 91 so that rotation is possible. In addition, stopper portions 95 that restrict the movement of the pulley portion 93 are fixed to both ends of the rail member 91. Therefore, the air curtain devices 20 and 40 are configured to move together by sliding the gantry 92 in the direction of the arrow X1 (X2) with respect to the rail member 91.

  The air curtain devices 20 and 40 are horizontally moved at positions spaced downward from the ceiling portion 13. Therefore, a sheet-like seal member 96 that closes the gap between the lower surface 13a and the upper surface 92a of the gantry 92 is provided. The seal member 96 has an upper end 96 a fixed to the lower surface 13 a of the ceiling portion 13 and a lower end 96 b fixed to the upper surface 92 a of the gantry 92. The upper end 96 a is fixed to the lower surface 13 a of the ceiling portion 13 corresponding to the center position (X direction) of the refrigerator compartment 10. Even when the gantry 92 is moved in the X direction, the seal member 96 deforms the cross-sectional shape into an S-shape, and the gap between the ceiling portion 13 and the gantry 92 is closed. Thereby, the air flow through the gap between the lower surface 13a and the upper surface 92a does not occur between the region 11 and the region 12.

  In the refrigerated warehouse 100, even when the gantry 92 is moved along the X direction and the volume ratio between the region 11 and the region 12 (the position of the boundary region 10b) is changed, the region of the air curtain devices 20 and 40 11 (region 12) side, the wind directions (angles α and β) and the wind speed of the rectified airflows P1 and P2 are adjusted individually.

  Specifically, as shown in FIG. 5, a position sensor 87 for detecting the position of the gantry 92 in the X direction is provided. Then, based on the detection result of the position sensor 87, the distance L1 between the cooling device 30 and the air curtain device 20 and the distance L2 (see FIG. 1) between the cooling device 50 and the air curtain device 40 are as shown in FIG. Reference).

  For example, as shown in FIG. 1, it is assumed that the gantry 92 is moved in the direction of the arrow X1, and the region 11 (distance L1) is relatively small and the region 12 (distance L2) is relatively large. In this case, as an example, the wind speed V1 of the airflow P1 from the air curtain device 20 is adjusted to be relatively small, and the wind speed V2 of the airflow P2 from the air curtain device 40 is adjusted to be relatively large. Furthermore, the angle α of the airflow P1 and the angle β of the airflow P2 are adjusted to each other.

(Planar structure of refrigerator compartment)
Further, when the refrigerator compartment 10 is viewed in a plan view, as shown in FIG. 6, the air curtain device 20 extends from the side wall portion 16 on one side to the side wall portion 17 on the other side. Two cooling devices 30 are arranged in a row under the lower surface 13a of the ceiling 13 near the side wall 15a of the region 11. Thereby, the cold air blown out from the air outlet 32 of the two cooling devices 30 is sucked into the air inlet 21 of the air curtain device 20. In addition, the number and arrangement configuration of the air curtain device 40 and the cooling device 50 installed on the region 12 side are symmetrical to the region 11 side.

  The side wall 16 is provided with an open / close door 18a, and the side wall 17 is provided with an open / close door 18b. On the outside of the refrigerator compartment 10, a loading space 101 for placing the articles 1 and 2 is installed. The truck 110 is configured to be able to come into contact with the loading area 101, and the cargo handling work for the articles 1 and 2 is performed at the loading area 101. The refrigerated warehouse 100 is configured in this way.

(Effect of 1st Embodiment)
In the first embodiment, the following effects can be obtained.

  In the first embodiment, as described above, the movable rectifying member 24 (rectifying mechanism unit 23) configured to rectify the blown air to each of the air curtain devices 20 and 40 and to adjust the wind direction of the rectified blown air. Is provided. Thereby, the air blown out from the air curtain devices 20 and 40 is blown out in a desired direction in a state in which the air flow rectifying property (uniformity of wind speed and straightness) is improved by the movable rectifying member 24. Therefore, even when the air curtain devices 20 and 40 are installed in the refrigerator compartment 10 and the regions 11 and 12 are thermally divided from each other without using a partition wall, the airflows P1 and P2 can be directed in a desired direction. Therefore, the optimum circulation flow G1 (vortex flow Q1) and circulation flow G2 (vortex flow Q2) for individually maintaining the temperatures of the regions 11 and 12 can be formed. Further, by forming the circulation flow G1 (vortex flow Q1) and the circulation flow G2 (vortex flow Q2) that are optimal for maintaining the temperature in the refrigerator compartment 10, the temperature unevenness in the region 11 and the temperature unevenness in the region 12 are reduced. Energy saving of the refrigerated warehouse 100 can be achieved as much as possible, and unnecessary cooling load is not generated in the cooling devices 30 and 50.

  In the first embodiment, the air curtain device 20 (40) is provided with an extendable member 27 for guiding the blown air to the movable rectifying member 24 by preventing the blown air from leaking from a portion other than the movable rectifying member 24, and A side plate member 28 is provided. Thereby, even if the movable rectifying member 24 capable of adjusting the wind direction of the blown air is provided, the blown air leaks from a portion other than the movable rectifying member 24 by the expansion and contraction member 27 and the side plate member 28 when the wind direction of the blown air is adjusted. Can be suppressed. Thereby, the turbulence of the air flow P1 (P2) around the movable rectifying member 24 can be suppressed, and the airflow P1 (P2) blown from the movable rectifying member 24 can be prevented from being insufficient. As a result, it is possible to reliably obtain the heat insulating function and heat insulating effect of the air flow P1 (vortex flow Q1) and the air flow P2 (vortex flow Q2) that thermally divide the regions 11 and 12 while forming the optimum circulation flows G1 and G2. it can.

  In the first embodiment, the air curtain devices 20 and 40 are arranged adjacent to each other along the boundary region 10b of the regions 11 and 12, and the airflows P1 and P2 blown from each of the air curtain devices 20 and 40 are in the X direction. The air flow direction of the blown air after rectification is adjusted by the movable rectification member 24 so as to increase the separation interval M. This prevents the airflows P1 and P2 blown out from each of the air curtain devices 20 and 40 from colliding with each other, so that the circulating flow G1 (vortex flow Q1) and the region 12 at the temperature T2 are maintained at the temperature T1. Thus, the circulation flow G2 (vortex flow Q2) that is maintained at a constant value can be reliably formed.

  Further, in the first embodiment, the expansion / contraction member 27 having the bellows structure expands / contracts according to the rotation amount of the movable rectifying member 24, thereby suppressing the leakage from portions other than the movable rectifying member 24 and moving the blown air. A space S leading to the rectifying member 24 is formed. Thereby, the space S that guides the blown air to the movable rectifying member 24 when the movable rectifying member 24 is rotated can be easily formed by utilizing the expansion and contraction of the expansion / contraction member 27 as the wind shielding member.

  In the first embodiment, the air direction of the blown air rectified by the movable rectifying member 24 is individually adjusted by the air curtain devices 20 and 40, thereby maintaining the region 11 at the temperature T1 and the region 12 at the temperature T2. To be configured. Thereby, no matter how the temperature T1 and the temperature T2 are set, the air direction of the blown air after rectification by the movable rectifying member 24 is individually adjusted by the air curtain devices 20 and 40, so that the temperature T1 and the temperature T2 are adjusted. It is possible to prevent the shape of the airflow P1 (P2) from being curved in the vicinity of the boundary region 10b due to the temperature difference between the current and the boundary region 10b. Accordingly, even in the vicinity of the boundary region 10b between the region 11 and the region 12, the temperature T1 on the region 11 side and the temperature T2 on the region 12 side can be easily maintained.

The telescopic member 327 has one end 327a fixed to the hook member 329 and the other end 327b fixed to the lower surface 320a. The elastic member 327 is connected (engaged) so that a plurality of plate members 327c can slide relative to each other. The plate members 327c are slid relative to each other so that the wind shielding function is maintained even when the respective engagement amounts (overlap amounts) are changed. Further, side plate members 28 that cover both ends of the movable rectifying member 24 in the Y direction are attached to the lower surface 320a.
