Description

  The present invention relates to a refrigerated warehouse, and more particularly to a refrigerated warehouse in which a refrigerated room is divided so that a plurality of regions are arranged adjacent to each other.

  Conventionally, a configuration is known in which a plurality of indoor regions are adjacently arranged without partitioning each other by a partition wall (see, for example, Patent Document 1).

  Patent Document 1 discloses a room air curtain provided with a line flow fan (air curtain device) that surrounds a central region of the room in a circumferential shape and generates an air curtain airflow that blows downward from the vicinity of the ceiling. Yes. In the room provided with the room air curtain described in Patent Document 1, the odor and smoke generated in the central region surrounded by the air curtain airflow are diffused into the room by the exhaust fan installed on the back of the ceiling. Without exhausting, the air is exhausted to the outside through the exhaust port of the ceiling. The air curtain airflow is adjusted so that it does not reach the floor surface. At the same time as the odor and smoke blocked by the air curtain airflow are exhausted from the ceiling side, the fresh air in the surrounding area of the living room is exhausted. Is supplied to the central region that is the source of odor (smoke) along the floor surface where the air curtain air current does not reach.

JP-A-7-19559

  However, in the room air curtain described in Patent Document 1, the air curtain airflow blown down from the vicinity of the ceiling does not reach the floor surface, and the air in the peripheral area is not near the floor surface. It is considered that the central region surrounded by the air curtain airflow and the outer peripheral region cannot be reliably divided because the air is drawn into the central region surrounded by the air curtain airflow. In addition, since the air in the peripheral area flows, the central area surrounded by the air curtain airflow and the peripheral area outside the center area cannot be thermally divided. For this reason, when the room air curtain of the said patent document 1 is applied with respect to the refrigerator warehouse provided with the refrigerator compartment containing the several area | region (article preservation | save area | region) arrange | positioned adjacently without partitioning with a partition etc. There is a problem in that it is difficult to form a plurality of article storage areas that can thermally maintain the individual temperatures by dividing the refrigerator compartment.

  The present invention has been made to solve the above-described problems, and one object of the present invention is to easily and thermally divide a plurality of adjacent article storage regions without being partitioned from each other. Thus, it is to provide a refrigerated warehouse capable of maintaining the temperature of each article storage area.

  To achieve the above object, a refrigerated warehouse according to one aspect of the present invention includes a first article storage area in which a first article is stored in a refrigerator and a second article storage area in which a second article is stored in a refrigerator. A refrigerator compartment in which the one article storage area and the second article storage area are arranged without being separated from each other by a partition, and a first air curtain airflow and a second air curtain airflow that are blown down to the floor of the refrigerator compartment are formed. In order to thermally divide the refrigerator compartment into a first article storage area maintained at the first temperature and a second article storage area maintained at the second temperature, the refrigerator compartment is installed on the first article storage area side.

By providing the air curtain device and the second air curtain device that forms the second air curtain airflow, the first air curtain from the first air curtain device at the boundary between the first article storage region and the second article storage region. Since both the air flow and the second air curtain air flow from the second air curtain device reach the floor of the refrigerator compartment, the heat transfer between the first article storage area and the second article storage area can be mutually blocked. so That. That is, a plurality of article storage areas arranged adjacent to each other without being partitioned from each other can be easily thermally divided. Thereby, the temperature maintenance of each article | item preservation | save area | region can be aimed at. In addition, the temperature distribution in the first article storage area (second article storage area) is suppressed as much as the temperature of each article storage area is maintained, and condensation or frosted state (frost formation) is generated in the refrigerator compartment. ) Can be suppressed. Thereby, since it can suppress that damage, such as a penetration | invasion of a water | moisture content, reaches each of a 1st article | item and a 2nd article | item, the high freshness of these articles | goods can also be maintained.

  Further, the refrigerated warehouse according to the first aspect includes a refrigeration room in which the first article storage area and the second article storage area are arranged adjacent to each other without being separated from each other by a partition wall, and the refrigeration room is maintained at the first temperature. By providing a first air curtain device and a second air curtain device for thermally dividing the first article storage region and the second article storage region maintained at the second temperature, Unlike the case where the second article storage area is partitioned using a partition wall, the operator freely travels between the first article storage area and the second article storage area and interrupts the work related to the first article and the second article. Can be done without. Unlike the case where the first article storage area or the second article storage area is temporarily moved out of the room (outside the refrigeration room) and moved to the other (room entry), intrusion of outside air (heat loss) due to opening / closing of a door or the like. ) Is also effectively suppressed, so that it is possible to effectively maintain the temperatures of the individual article storage regions.

That is, at least one of the first air circulation flow or the second air circulation flow (cold air) gradually falls in the gravity downward direction by its own weight, and thus the corresponding first air curtain device or second air curtain. It is suppressed that these air flow shapes are disturbed by directly hitting the first air curtain air flow or the second air curtain air flow without reaching the suction port of the apparatus. As a result, it is possible to reliably form the first air circulation flow in the first article storage region by operating the first air curtain device and the first blower device. Further, the second air curtain device and the second air blower can be operated to reliably form the second air circulation flow in the second article storage area.

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

(First embodiment)
First, with reference to FIGS. 1-3, the refrigerated warehouse 100 by 1st Embodiment of this invention is demonstrated.

  As shown in FIG. 1, the refrigerated warehouse 100 according to the first embodiment is a refrigerated warehouse capable of storing a plurality of different types of articles (products) while the internal space 10 a is maintained at a predetermined temperature. . Specifically, the refrigerated warehouse 100 includes a refrigerated room 10 having an internal space 10a. In addition, the internal space 10a includes an area 11 for storing an article 1 such as frozen food at a predetermined temperature and an area for storing an article 2 such as another food refrigerated at a predetermined temperature different from the article 1. 12. In this case, the area 11 is maintained at the temperature T1 for storing the article 1 in a frozen state, and the area 12 is maintained at the temperature T2 for storing the article 2 in a refrigerator. Here, the temperature T1 is lower than the temperature T2. The articles 1 and 2 are examples of the “first article” and the “second article” of the present invention, respectively. Further, the temperature T1 and the temperature T2 are examples of the “first temperature” and the “second temperature” in the present invention, respectively. Area 11 and area 12 are examples of the “first article storage area” and the “second article storage area” of the present invention, respectively.

  Here, the internal space 10a is not divided into a region 11 on the X1 side and a region 12 on the X2 side by providing a partition for physically partitioning (partitioning) the inside of the refrigerator compartment 10. That is, the boundary region 10b between the region 11 and the region 12 is not provided with a heat insulating partition wall or a structure such as a door that can be partially opened and closed. Therefore, an operator (worker (not shown)) who works on the article 1 in the area 11 moves to the area 12 by passing through the boundary area 10b in the direction of the arrow X2, and continues to work on the article 2. Is configured to be possible. An operator (not shown) can pass through the boundary region 10b from the region 12 to the region 11 as well.

  In addition, as described above, the region 11 and the region 12 that are not partitioned from each other by using a physical partition in the refrigerator compartment 10 are maintained at the refrigerator temperatures including the different temperatures T1 and T2, respectively. It is configured. That is, the region 11 and the region 12 are configured to be thermally divided into the temperature T1 and the temperature T2 without using a partition wall.

  In order to thermally divide the inside of the refrigerator compartment 10, in the first embodiment, the air curtain device 20 and the air curtain device 40 each have a blowing function in the boundary region 10b where the region 11 and the region 12 face each other. Is installed. The air curtain device 20 has a function of forming an air flow P1 that is blown down to the floor surface 14 of the refrigerator compartment 10, and the air curtain device 40 has a function of forming an air flow P2 that is blown down to the floor surface 14. Yes. The air curtain device 20 and the air curtain device 40 are examples of the “first air curtain device” and the “second air curtain device” of the present invention, respectively. The airflow P1 and the airflow P2 are examples of the “first air curtain airflow” and the “second air curtain airflow” of the present invention, respectively.

  As a result, in the boundary region 10b, the airflow P1 from the air curtain device 20 and the airflow P2 from the air curtain device 40 both reach the floor surface 14 of the refrigerating room 10, so that the X between the region 11 and the region 12 Heat transfer along the direction (in this case, heat transfer from the region 12 having the temperature T2 to the region 11 having the temperature T1) is blocked. The air curtain device 20 is installed on the lower surface 13a of the ceiling portion 13 corresponding to the X1 side edge of the boundary region 10b, and the air curtain device 40 corresponds to the X2 side edge of the boundary region 10b. It is installed on the lower surface 13 a of the ceiling portion 13. Further, the air curtain device 20 and the air curtain device 40 are arranged with the boundary region 10b sandwiched between the floor surface 14 and the same height position (Z direction).

  Moreover, in 1st Embodiment, as shown in FIG. 1, in addition to the air curtain apparatus 20, the area | region 11 in the refrigerator compartment 10 has the cooling function which cools the area | region 11 with the ventilation function, and maintains it at temperature T1. A cooling device 30 is installed. Similarly, in addition to the air curtain device 40, a cooling device 50 having a cooling function for cooling the region 12 and maintaining the temperature T2 in addition to the air curtain device 40 is installed in the region 12. Specifically, the cooling device 30 is installed on the upstream side (X1 side) from the suction port 21 for sucking the cold air circulation flow G1 in the air curtain device 20, and the cooling device 50 is connected to the cold air circulation in the air curtain device 40. It is installed on the upstream side (X2 side) of the suction port 41 for sucking the flow G2. The cooling device 30 and the cooling device 50 are examples of the “first blower” and the “second blower” in the present invention, respectively. The cold air circulation flow G1 and the cold air circulation flow G2 are examples of the “first air circulation flow” and the “second air circulation flow” of the present invention, respectively.

  Thereby, in the area | region 11, the cold air circulation flow G1 containing the air flow P1 for operating the air curtain apparatus 20 and the cooling device 30 and thermally dividing the inside of the refrigerator compartment 10 is formed. Moreover, in the area | region 12, it is comprised so that the cold air circulation flow G2 containing the air flow P2 for operating the air curtain apparatus 40 and the cooling device 50 and thermally dividing the inside of the refrigerator compartment 10 may be formed. .

  Here, the flow of airflow (cold air) will be described. As shown in FIG. 1, in the region 11, the cool air cooled by the cooling device 30 and blown out from the air outlet 32 of the cooling device 30 travels along the bottom surface 13 a of the ceiling portion 13 in the direction of the arrow X <b> 2 (horizontal direction). It is sucked into the suction port 21 of the curtain device 20. The cold air changes its direction and becomes an air flow P1 from the air outlet 22 of the air curtain device 20 and is blown obliquely downward (in the direction of arrow Z2 and in the direction of arrow X1). That is, the blower outlet 22 has an opening shape that forms the airflow P1 in which the cool air blown out is directed to the region 11 side (X1 side) by a predetermined angle from directly below. Thereafter, after the cold air (air flow P1) reaches the floor surface 14, the direction is changed and most of the cold air is circulated along the floor surface 14 along the arrow X1 direction, and the vicinity of the side wall portion 15a on the X1 side is transmitted in the arrow Z1 direction. Then, the air is sucked into the suction port 31 of the cooling device 30. In this way, a cold air circulation 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 is also changed in the direction of the arrow X2, and then rises in the direction of the arrow Z1 in the boundary region 10b and is mixed with the cool air from the outlet 22 again. Therefore, a small vortex flow Q1 (counterclockwise) is also generated in the boundary region 10b.

  In the region 12, the cool air cooled by the cooling device 50 and blown out from the outlet 52 of the cooling device 50 travels along the lower surface 13 a of the ceiling portion 13 in the direction of the arrow X <b> 1 (horizontal direction) and is sucked into the air curtain device 40. Inhaled into mouth 41. The cold air changes its direction and is blown obliquely downward (arrow Z2 direction and arrow X2 direction) from the air outlet 42 of the air curtain device 40. That is, the blower outlet 42 has such an opening shape that the cold air blown out forms an airflow P2 that is directed from the directly downward direction to the region 12 side (X2 side) by a predetermined angle. Thereafter, after the cold air (air flow P2) reaches the floor surface 14, the direction is changed and most of the cold air is circulated along the floor surface 14 along the arrow X2 direction, and the vicinity of the side wall 15b on the X2 side is transmitted in the arrow Z1 direction. Then, the air is sucked into the suction port 51 of the cooling device 50. Thus, by operating the air curtain device 40 and the cooling device 50, a cold air circulation flow G <b> 2 that circulates largely counterclockwise is formed in the region 12. A part of the airflow P2 that has reached the floor surface 14 is also changed in the direction of the arrow X1, and then rises in the direction of the arrow Z1 in the boundary region 10b and is mixed with the cold air from the air outlet 42 again. Therefore, a small eddy current Q2 (clockwise) is also generated in the boundary region 10b.

  In the boundary region 10b, the vortex flows Q1 and Q2 are generated, but the air flow P1 blown down from the outlet 22 of the air curtain device 20 in the cold air circulation flow G1 and the air curtain device in the cold air circulation flow G2. The airflow P2 blown down from the 40 air outlets 42 has a mode in which the airflow P2 is translated in a slightly divergent shape along the downward direction (arrow Z2 direction). In the first embodiment, it is prevented that the airflow P1 and the airflow P2 are attracted to each other and merge to form one descending airflow in the boundary region 10b. Further, the vortex flows Q1 and Q2 are generated, and the air flow P1 and the air flow P2 are blown down while being separated, so that the region 11 and the region 12 are thermally divided. Therefore, even if an operator (not shown) freely travels between the region 11 and the region 12 via the boundary region 10b, the region 11 and the region 12 have different in-call temperatures (temperatures T1 and T2). ) Is maintained without significant disruption.

  Further, when the refrigerator compartment 10 is viewed in a plan view, as shown in FIG. 2, the air curtain device 20 installed on the region 11 side is from the side wall portion 16 on one side (Y1 side) constituting the internal space 10a. It is installed over the side wall 17 on the other side (Y2 side). In this case, four air curtain devices 20 whose longitudinal direction is the Y direction are linearly arranged along the Y direction on the lower surface 13 a of the ceiling portion 13. Further, under the lower surface 13a of the ceiling portion 13 in the vicinity of the side wall portion 15a (X1 side) of the region 11, two cooling devices 30 whose Y direction is the longitudinal direction are linearly arranged in the Y direction. Thus, the configuration is such that the cold air blown from the respective outlets 32 (see FIG. 1) of the two cooling devices 30 is sucked into the respective inlets 21 (see FIG. 1) of the four air curtain devices 20. Has been. Note that the number and arrangement of the air curtain device 40 and the cooling device 50 installed on the region 12 side are also symmetrical with the region 11 side.

  Further, as a control configuration for maintaining the temperature in the refrigerator compartment 10 in the refrigerator warehouse 100, a controller device 70 is installed outside the refrigerator warehouse 100 as shown in FIG. The controller device 70 includes an overall control unit 71, an air curtain device control unit 72, a cooling device control unit 73, an air curtain device control unit 74, and a cooling device control unit 75.

In this way, a cold air circulation flow G1 that circulates greatly in the clockwise direction is formed in the region 11.

  In contrast, in the region 12, the cool air cooled by the air curtain device 240 (cooling unit 4) is blown obliquely downward (in the direction of arrow Z <b> 2 and in the direction of arrow X <b> 2) from the outlet 42 of the air curtain device 240. After reaching the floor surface 14, the cold air changes direction and flows along the floor surface 14 in the direction of the arrow X <b> 2, and travels near the side wall portion 15 b on the X2 side in the direction of the arrow Z <b> 1 to the suction port 51 of the cooling device 50. Inhaled. Then, the cool air blown out from the blowout port 52 by the blowing function of the cooling device 50 is sucked into the suction port 41 of the air curtain device 40 along the lower surface 13a of the ceiling portion 13 in the direction of the arrow X1 (horizontal direction). In this manner, a cold air circulation flow G2 that circulates largely counterclockwise is formed in the region 12.

  As a result, in the boundary region 10b between the region 11 and the region 12, the air flow P1 from the air curtain device 220 and the air flow P2 from the air curtain device 240 both reach the floor surface 14 of the refrigerator compartment 10, so that the region 11 The heat transfer along the X direction between the region 12 and the region 12 is blocked from each other.

The remaining effects of the second embodiment are similar to those of the aforementioned first embodiment.

(Third embodiment)
Next, a third embodiment will be described with reference to FIGS. 5 and 6. In the third embodiment, unlike the first embodiment, an example in which the airflow direction guide member 301 is attached to the cooling device 330 and the cooling device 350 will be described. The cooling device 330 and the cooling device 350 are examples of the “first blower” and the “second blower” in the present invention, respectively. In the figure, components similar to those in the first embodiment are denoted by the same reference numerals as those in the first embodiment.

  As shown in FIG. 5, the refrigerated warehouse 300 according to the third embodiment of the present invention includes the air curtain device 20 and the cooling device 330 on the region 11 side, and the air curtain device 40 and the cooling device 350 on the region 12 side. It is installed. When the refrigerator compartment 10 is viewed in a plan view, as shown in FIG. 6, one cooling device 330 is arranged in the region 11, and one cooling device 350 is arranged in the region 12. Yes. Therefore, after the cold air blown from one cooling device 330 is sucked into the four air curtain devices 20, it is blown downward (obliquely downward) through each of the four air curtain devices 20. An air flow P1 is formed. Moreover, after the cold air blown out from one cooling device 50 is sucked into the four air curtain devices 40, the cold air is blown downward (obliquely downward) through each of the four air curtain devices 40. An airflow P2 is formed.

  Here, in 3rd Embodiment, as shown in FIG. 5, the wind direction guide member 301 is attached to the cooling devices 330 and 350, respectively. The configuration of the wind direction guide member 301 will be described by taking the cooling device 330 side as an example.

  That is, the airflow direction guide member 301 is formed along a plate-like lower plate 302 that suppresses the air circulation flow G1 blown from the outlet 32 of the cooling device 330 from immediately going downward (in the direction of arrow Z2), and the lower plate 302. A plurality of (six) plate-like rectifying plates 303 arranged on the lower plate 302 so as to widen the horizontal width (Y direction) of the circulating air flow G1 in the horizontal plane toward the suction port 21 of the air curtain device 20. And have. Moreover, the wind direction guide member 301 does not have a rectangular or annular cross-sectional shape that is closed like a general duct member, but has a cross-sectional shape that is open without being closed. In this case, the upper surface side (Z1 side) of the wind direction guide member 301 facing the ceiling portion 13 is opened without being closed. Therefore, the wind direction guide member 301 has a function of guiding the air circulation flow G <b> 1 blown out from the cooling device 330 to the suction port 21 of the air curtain device 20. The lower plate 302 and the rectifying plate 303 are examples of the “first wind direction plate” and the “second wind direction plate” of the present invention, respectively.

  Therefore, when the region 11 is viewed from the side, the cold air blown out from the air outlet 32 of the cooling device 330 is in a state where the lower plate 302 suppresses the height position in the Z direction from moving downward. It is sucked into the suction port 21 of the air curtain device 20 along the lower surface 13a of the portion 13 in the direction of arrow X2 (horizontal direction). Further, when the region 11 is viewed from above, as shown in FIG. 6, the cold air blown from the outlet 32 of the cooling device 330 is caused to flow in the horizontal plane of the air circulation flow G1 by the six rectifying plates 303. It flows so as to widen the lateral width (Y direction) toward the suction port 21 of the air curtain device 20 and is sucked into the suction port 21 of the air curtain device 20.

  In addition, the wind direction guide member 301 attached to the cooling device 350 side in the region 12 is configured similarly to the wind direction guide member 301 attached to the cooling device 330 side in the region 11. Therefore, the cold air blown out from the outlet 52 of the cooling device 350 has the air circulation flow G2 generated by the six rectifying plates 303 in a state in which the lower plate 302 suppresses the height position in the Z direction downward. The horizontal width in the horizontal plane (Y direction) flows so as to widen toward the suction port 41 of the air curtain device 40 and is sucked into the suction port 41 of the air curtain device 40. In addition, the other structure of the refrigerated warehouse 300 by 3rd Embodiment is the same as that of the said 1st Embodiment.

  In the third embodiment, the following effects can be obtained.

  In 3rd Embodiment, the airflow direction guide member 301 which has the cross-sectional shape open | released without closing for guiding the cold-air circulation flow G1 blown out from the cooling device 330 to the suction inlet 21 of the air curtain apparatus 20 as mentioned above. Is provided in the cooling device 30. In addition, the cooling device 350 is provided with a wind direction guide member 301 having a cross-sectional shape that is open without being closed for guiding the cold air circulation flow G2 blown out from the cooling device 350 to the suction port 41 of the air curtain device 40. Thus, by providing the airflow direction guide member 301 in the cooling devices 330 and 350, the cold air circulation flow G1 from the cooling device 330 and the cold air circulation flow G2 from the cooling device 350 are converted into the suction port 21 of the corresponding air curtain device 20 and Each can easily reach the suction port 41 of the air curtain device 40. That is, the cold air circulation flows G1 and G2 (cold air) gradually fall in the gravity downward direction due to their own weight, and thus the corresponding suction port 21 of the air curtain device 20 and the suction port 41 of the air curtain device 40. Disturbing these airflow shapes by directly hitting the airflow P1 or the airflow P2 without reaching each other is suppressed. As a result, the air curtain device 20 and the cooling device 330 can be operated to reliably form the cold air circulation flow G1 in the region 11. In addition, the air curtain device 40 and the cooling device 350 can be operated to reliably form the cold air circulation flow G2 in the region 12.

  Moreover, in 3rd Embodiment, it connects to the lower end part of the blower outlet 32 (52) of the cooling device 330 (350), the cold-air circulation flow G1 blown out from the blower outlet 32 of the cooling device 330, and the blower outlet of the cooling device 350 52, a plate-like lower plate 302 that suppresses the cold air circulation flow G2 blown out from 52 from flowing downward (in the direction of arrow Z2), and the horizontal widths of the cold air circulation flows G1 and G2 flowing along the lower plate 302 in the horizontal plane. A wind direction guide is formed by a plate-like rectifying plate 303 arranged on the lower plate 302 so as to widen (Y direction) toward the suction port 21 of the corresponding air curtain device 20 and the suction port 41 of the air curtain device 40. The member 301 is configured. Accordingly, the lower plate 302 can easily maintain the height position in the Z direction of the cold air circulation flow G1 from the cooling device 330 toward the air curtain device 20 and the cold air circulation flow G2 from the cooling device 350 toward the air curtain device 40. Can do. Further, the rectifying plate 303 directs the cold air circulation flow G1 from the cooling device 330 and the cold air circulation flow G2 from the cooling device 350 toward the suction port 21 of the corresponding air curtain device 20 and the suction port 41 of the air curtain device 40. Each can be evenly reached while being easily diffused. Therefore, since the blowing temperature and the airflow shape of each of the airflows P1 and P2 formed in a line along the width direction (Y direction) of the refrigerator compartment 10 are made uniform, the cold air circulation flow G1 constituting the airflow P1. And the cold air circulation flow G2 which comprises the airflow P2 can be formed appropriately. As a result, the region 11 and the region 12 can be reliably divided thermally. The remaining effects of the third embodiment are similar to those of the aforementioned first embodiment.

The auxiliary blower 402 is further provided between the two.

  As a result, in the region 11, the cold air cooled by the cooling device 330 and blown out from the airflow direction guide member 301 is sucked into the auxiliary air blower 401 through the lower surface 13 a of the ceiling portion 13 in the direction of the arrow X <b> 2 (horizontal direction). Further, the cold air blown out from the auxiliary blower 401 is sucked into the suction port 21 of the air curtain device 20. The cold air changes its direction and is blown obliquely downward (in the direction of arrow Z2 and in the direction of arrow X1) from the air outlet 22 of the air curtain device 20 and reaches the floor surface 14. Then, the air flow is changed along the direction of the arrow X1 by changing the direction, and the vicinity of the side wall 15a on the X1 side is transmitted in the direction of the arrow Z1 so as to be sucked into the suction port 31 of the cooling device 30. Is formed.

  As for the cool air circulation flow G2 in the region 12, the cool air cooled by the cooling device 350 and blown out from the wind direction guide member 301 is transmitted along the lower surface 13a of the ceiling portion 13 in the arrow X1 direction (horizontal direction), and the auxiliary air blower 402. Sucked into. Further, the cold air blown out from the auxiliary blower 402 is sucked into the suction port 41 of the air curtain device 40. The cold air changes its direction and blows obliquely downward (in the direction of arrow Z2 and in the direction of arrow X2) from the air outlet 42 of the air curtain device 40 and reaches the floor surface 14. Then, the cold air circulation flow G2 is circulated through the floor surface 14 along the direction of the arrow X2 by changing the direction so as to be sucked into the suction port 51 of the cooling device 350 along the side of the side wall 15b on the X2 side in the direction of the arrow Z1. Is formed. In addition, the other structure of the refrigerator warehouse 400 by 4th Embodiment is the same as that of the said 1st Embodiment.

  In the fourth embodiment, the following effects can be obtained.

  In the fourth embodiment, as described above, the auxiliary air blower 401 is provided between the cooling device 330 (wind direction guide member 301) and the air curtain device 20, and the cooling device 350 (wind direction guide member 301) and the air curtain device. 40 is provided with an auxiliary air blower 402. Then, the cool air circulation flow G1 blown out from the cooling device 330 (wind direction guide member 301) and the cold air circulation flow G2 blown out from the cooling device 350 (wind direction guide member 301) are converted into the suction port 21 of the corresponding air curtain device 20 and The air curtain device 40 is configured to reach each of the suction ports 41. As a result, the cold air circulation flow G <b> 1 from the cooling device 330 (wind direction guide member 301) can reliably reach the suction port 21 of the air curtain device 20 by the auxiliary blower 401. Further, the auxiliary air blower 402 can reliably cause the cool air circulation flow G2 from the cooling device 350 (the wind direction guide member 301) to reach the suction port 41 of the air curtain device 40. Therefore, the cold air circulation flow G1 can be reliably formed in the region 11, and the cold air circulation flow G2 can be reliably formed in the region 12. The remaining effects of the fourth embodiment are similar to those of the aforementioned first embodiment.

(Fifth embodiment)
Next, a fifth embodiment will be described with reference to FIGS. 8 and 9. In the fifth embodiment, unlike the first embodiment, an example in which the wind velocity and the wind direction of each of the airflow P1 and the airflow P2 are adjusted will be described. In the figure, components similar to those in the first embodiment are denoted by the same reference numerals as those in the first embodiment.

  As shown in FIG. 8, the refrigerated warehouse 500 according to the fifth embodiment of the present invention is provided with the air curtain device 20 and the cooling device 30 on the region 11 side, and the air curtain device 40 and the cooling device 50 on the region 12 side. It is installed.

  Further, the air curtain device 20 is provided with a louver mechanism 23 that can be rotated outside the air outlet 22, and the air curtain device 40 is provided with a louver mechanism 43 that can be rotated outside the air outlet 42. ing. That is, the airflows P1 and P2 have a wind direction angle α and a wind direction angle β with respect to the vertical direction (Z direction), respectively, according to the rotation angle of the louver mechanisms 23 and 43 (the inclination angle of the blade portion). It is comprised so that it may be blown down downward (diagonally downward).

  Here, in the fifth embodiment, the wind speed V1 and the wind direction angle α of the air flow P1, and the wind speed V2 and the wind direction angle β of the air flow P2 are determined based on the temperature T1 of the region 11 and the temperature T2 of the region 12. The temperature T1 is maintained, and the region 12 is adjusted to be maintained at the temperature T2.

  Specifically, as shown in FIG. 9, in the refrigerator compartment 10, in addition to the temperature sensors 81 and 82, a temperature sensor 83 for detecting the air temperature in the vicinity of the floor 14 in the boundary region 10b is provided. . As shown in FIG. 8, the temperature sensor 81 is fixedly installed near the air outlet 22 of the air curtain device 20, and the temperature sensor 82 is fixedly installed near the air outlet 42 of the air curtain device 40. . Therefore, the temperature sensor 81 detects the blowing temperature of the airflow P1 blown from the outlet 22 and the temperature sensor 82 detects the blowing temperature of the airflow P2 blown from the outlet 42. . Then, the overall control unit 71 performs a predetermined calculation process based on each temperature detected by the temperature sensors 81 to 83, and the air flow rate (air flow) of each of the air curtain devices 20 and 40 based on the calculation process result. The rotation speed of the fan) and the rotation angle control of the louver mechanisms 23 and 43 are performed. The temperature sensor 81 and the temperature sensor 82 are examples of the “first temperature sensor” and the “second temperature sensor” of the present invention, respectively.

  Thus, as shown in FIG. 8, the wind speed V1 and the wind direction angle α of the air flow P1 and the wind speed V2 and the wind direction angle β of the air flow P2 are respectively adjusted and controlled, so that the region 11 is maintained at the temperature T1 and the region 12 Is maintained at the temperature T2. In particular, when the difference between the temperature T1 and the temperature T2 is large, the operation state (wind speed and wind direction angle) of the air curtain devices 20 and 40 based on each temperature detected by the temperature sensors 81 to 83 is appropriately performed. Thus, the temperature maintenance management of the areas 11 and 12 is appropriately achieved.

  As an example, for example, the temperature sensor 81 detects the blowing temperature of the airflow P1 as 0 degrees Celsius, the temperature sensor 82 detects the blowing temperature of the airflow P2 as 10 degrees Celsius, and the temperature sensor 83 detects the floor surface 14 in the boundary region 10b. Assume that the temperature in the vicinity is detected at 2 degrees Celsius. In this case, the vortex flow Q1 that the air flow P1 collides with the floor surface 14 and reaches the temperature sensor 83 is in a state that the vortex flow Q2 that collides with the floor surface 14 and reaches the temperature sensor 83 is more in a state. It is determined by the control unit 71 (see FIG. 9).

  Then, the current wind speed V1 and the wind direction angle α of the air flow P1 of the air curtain device 20 and the air flow P2 of the air curtain device 40 decrease the wind speed V1 with the current wind speed V2 and the wind direction angle β as a reference to reduce the wind direction angle α. The first control for increasing the wind speed (wider from the vertical direction) is performed alone, or the second control for increasing the wind speed V2 and decreasing the wind direction angle β (closer to the vertical direction) is performed alone, or this The overall control unit 71 (see FIG. 9) determines whether to perform the third control that simultaneously performs the first control and the second control. Which of the first control to the third control is performed is based on a predetermined algorithm with reference to the detected values of the temperature sensors 81 to 83, the wind speed V1 (V2), and the wind direction angle α (β) at that time. It may be configured to be determined. Alternatively, the control amounts (the control amounts of the wind speeds V1 and V2 and the wind direction angles α and β) for each detected value are configured to be realized using a predetermined control table (not shown) or the like. May be.

  Thereby, the air volume that forms the vortex Q1 is gradually reduced, and conversely, the air volume that forms the vortex Q2 is gradually increased. Therefore, the temperature in the vicinity of the floor 14 in the boundary region 10b is gradually increased from the state of 2 degrees until then to an intermediate temperature between the temperature T1 (about 0 degrees) and the temperature T2 (about 10 degrees). . As described above, even when the refrigerated warehouse 500 is configured so that a significant temperature difference is generated between the temperature T1 and the temperature T2 by making the airflow shapes of the airflow P1 and the airflow P2 asymmetrical. The air in the region 11 and the air in the region 12 are not mixed as much as possible due to the temperature difference between the temperature T1 and the temperature T2 (in this case, about 10 degrees). Also, by providing a difference in wind speed (difference between V1 and V2) and an angular difference (difference between α and β) between the airflow P1 and the airflow P2, the airflow P1 and the airflow P2 are sucked and joined together. The formation of one downdraft in the boundary region 10b is prevented.

  The temperature sensor 81 (82) is provided in each of the four air curtain devices 20 (40). Moreover, the temperature sensor 83 is installed so that the air temperature of the floor surface 14 vicinity in the center part of the Y direction of the refrigerator compartment 10 may be detected. From the temperature relationship between the pair of temperature sensors 81 and 82 facing in the X direction across the boundary region 10b and the temperature sensor 83 in the center in the Y direction, the wind speed and direction of the four air curtain devices 20 (40) are It is configured to be adjusted individually. That is, the air curtain device control unit 72 (74) shown in FIG. 9 is configured to individually control the four air curtain devices 20 (40). In addition, the other structure of the refrigerator warehouse 500 by 5th Embodiment is the same as that of the said 1st Embodiment.

  In the fifth embodiment, the following effects can be obtained.

  In the fifth embodiment, as described above, the wind speed V1 and the wind direction angle α of the airflow P1, and the wind speed V2 and the wind direction angle β of the airflow P2 are set to the detected value of the temperature T1, the detected value of the temperature T2, and the boundary region 10b. Based on the three factors of the detected air temperature in the vicinity of the floor 14, adjustment is performed so that the region 11 can be maintained at the temperature T1 and the region 12 can be maintained at the temperature T2. Thereby, no matter how the temperature T1 and the temperature T2 are set to each other, the wind speed V1 and the wind direction angle α of the air flow P1, and the wind speed V2 and the wind direction angle β of the air flow P2 are detected as the temperature T1. Is adjusted based on the value, the detected value of the temperature T2, and the detected value of the air temperature in the vicinity of the floor 14 in the boundary region 10b, so that the regions 11 and 12 are caused by the temperature difference between the temperature T1 and the temperature T2. In the vicinity of the boundary region 10b, the shape of the air curtain airflow (airflows P1 and P2) can be prevented from being distorted (curved). 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.

  In the fifth embodiment, the temperature sensor 81 that detects the temperature T1 of the region 11, the temperature sensor 82 that detects the temperature T2 of the region 12, and the temperature sensor that detects the air temperature near the floor 14 in the boundary region 10b. 83.

It adjusts so that it can maintain at temperature T2. Thereby, based on the detection result of the temperature sensors 81-83, the wind speed V1 and the wind direction angle (alpha) of the airflow P1, and the wind speed V2 and the wind direction angle (beta) of the airflow P2 can be adjusted accurately. That is, in the vicinity of the boundary region 10b between the region 11 having the temperature T1 and the region 12 having the temperature T2, the airflow P1 and the airflow P2 are easily mixed due to the temperature difference between the temperature T1 and the temperature T2. Can be suppressed. Further, the thermal boundary position between the region 11 and the region 12 can be appropriately controlled. The remaining effects of the fifth embodiment are similar to those of the aforementioned first embodiment.

(Sixth embodiment)
Next, a sixth embodiment will be described with reference to FIG. In the sixth embodiment, unlike the first embodiment, an example in which a shielding member 601 is provided between the air curtain device 20 and the air curtain device 40 will be described. In the figure, components similar to those in the first embodiment are denoted by the same reference numerals as those in the first embodiment.

  As shown in FIG. 10, the refrigerated warehouse 600 according to the sixth embodiment of the present invention has the air curtain device 20 and the cooling device 30 installed on the region 11 side, and the air curtain device 40 and the cooling device 50 on the region 12 side. It is installed. Here, in the sixth embodiment, a shielding member 601 having a heat insulating function is provided between the air curtain devices 20 and 40. The shielding member 601 is made of a transparent member having heat insulation properties. The shielding member 601 includes an upper end 601a attached to the lower surface 13a of the ceiling portion 13 and a lower end 601b positioned at a position higher than the floor surface 14 of the refrigerator compartment 10. And is formed in a plate shape.

  Thereby, in the boundary region 10b, the airflow P1 immediately after being blown down from the air curtain device 20 and the airflow P2 immediately after being blown down from the air curtain device 40 are not interfered with each other by the shielding member 601. Head to face 14. That is, the role of the heat insulation wall by the air currents P1 and P2 is maintained without significantly disturbing the air current shape formed in the boundary region 10b. Therefore, the airflow P1 and the airflow P2 are mixed due to the temperature difference between the temperature T1 and the temperature T2, and the shape of the air curtain airflow (airflows P1 and P2) is near the boundary region 10b between the region 11 and the region 12. The distortion (curving) is configured to be suppressed by the rectifying action of the shielding member 601.

  Here, for example, when the temperature T1 is set relatively high with respect to the temperature T2 and the shielding member 601 is not provided, the high-temperature eddy current Q1 is heated in the upper region in the boundary region 10b. Simultaneously with the low vortex flow Q2, the low temperature vortex flow Q2 is mixed with the high temperature vortex flow Q1 in the lower region of the boundary region 10b. Thereby, in the vicinity of the boundary region 10b, the shape of the air curtain airflow (airflows P1 and P2) is distorted so as to flow from the upper right to the lower left. On the other hand, in the refrigerated warehouse 600, since the shielding member 601 is provided, the shape of the air curtain airflow (airflows P1 and P2) is configured not to cause significant distortion.

  In addition, the height position of the lower end 601b of the shielding member 601 is adjusted to a position where an operator (not shown) does not hinder the traffic between the area 11 and the area 12. In addition, the other structure of the refrigerator warehouse 600 by 6th Embodiment is the same as that of the said 1st Embodiment.

  In the sixth embodiment, the following effects can be obtained.

  In the sixth embodiment, as described above, it is provided between the air curtain device 20 and the air curtain device 40, and the lower end 601b is positioned higher than the floor surface 14 of the refrigerating chamber 10, and the air flows P1 and P2 are connected to each other. A shielding member 601 for shielding is further provided. Thereby, no matter how the temperature T1 and the temperature T2 are set to each other, the lower end 601b provided between the air curtain devices 20 and 40 extends to a position higher than the floor surface 14 of the refrigerator compartment 10. The shielding member 601 can reach the floor surface 14 of the refrigerator compartment 10 without disturbing the shapes of the airflows P1 and P2. That is, the shielding member 601 prevents the air curtain airflow (airflows P1 and P2) from being distorted (curved) in the vicinity of the boundary region 10b between the region 11 and the region 12 due to the temperature difference between the temperature T1 and the temperature T2. This can be suppressed by the rectifying action. Therefore, the temperature T1 and the temperature T2 can be easily maintained in the vicinity of the boundary region 10b between the region 11 and the region 12, respectively.

  Moreover, in 6th Embodiment, the shielding member 601 is comprised using the transparent member which has heat insulation. Thereby, even if it is a case where the shielding member 601 which shields partially the area | region 11 and the area | region 12 is installed, since the shielding member 601 consists of a transparent member, an operator looks over the area | region 11 and the area | region 12 mutually. be able to. This also makes it possible to improve workability. The remaining effects of the sixth embodiment are similar to those of the aforementioned first embodiment.

(Modification of the sixth embodiment)
Next, a modification of the sixth embodiment will be described with reference to FIG. In the modified example of the sixth embodiment, unlike the sixth embodiment, the air curtain device 20 and the air curtain device 40 are arranged in a state of being separated downward (in the direction of arrow Z2) from the lower surface 13a of the ceiling portion 13. A description will be given of an example in which the shield member 602 configured to be provided is fixed in the refrigerator compartment 10. In the figure, components similar to those in the sixth embodiment are denoted by the same reference numerals as those in the sixth embodiment.

  As shown in FIG. 11, a refrigerator warehouse 650 according to a modification of the sixth embodiment of the present invention has a plate-like shielding member 602 having an upper end 602a and attached to the lower surface 13a of the ceiling portion 13. ing. The air curtain devices 20 and 40 are respectively attached to the side surface 603 (X1 side) and the side surface 604 (X2 side) of the shielding member 602 while being spaced downward from the lower surface 13a of the ceiling portion 13. In this state, the lower end 602 b of the shielding member 602 extends so as to be held at a position higher than the floor surface 14.

  Thereby, since the shielding member 602 extending downward from the air curtain device 20 (40) is provided in the refrigerated warehouse 650 regardless of the installation position of the air curtain devices 20 and 40 in the height direction, the air curtain airflow The shape of the (airflows P1 and P2) is configured not to cause significant distortion. In addition, the other structure of the refrigerator warehouse 650 by the modification of 6th Embodiment is the same as that of the said 1st Embodiment.

  In the modification of the sixth embodiment, the following effects can be obtained.

  In the modification of the sixth embodiment, as described above, each of the air curtain device 20 and the air curtain device 40 can be arranged in a state where the air curtain device 20 and the air curtain device 40 are spaced apart downward (in the direction of arrow Z2) from the lower surface 13a of the ceiling portion 13. 602 is provided in the refrigerator compartment 10. Thereby, irrespective of the installation positions of the air curtain devices 20 and 40 in the height direction (Z direction), the shape of the airflows P1 and P2 is no matter how the temperature T1 and the temperature T2 are set. Can reach the floor surface 14 of the refrigerator compartment 10 without disturbing both. Therefore, the temperature T1 and the temperature T2 can be easily maintained in the region 11 and the region 12, respectively. The remaining effects of the modification of the sixth embodiment are similar to those of the aforementioned first embodiment.

(Seventh embodiment)
Next, a seventh embodiment will be described with reference to FIGS. In the seventh embodiment, unlike the first embodiment, an example in which the air curtain device 20 and the air curtain device 40 are configured to be movable in the X direction along the lower surface 13a of the ceiling portion 13 will be described. In the figure, components similar to those in the first embodiment are denoted by the same reference numerals as those in the first embodiment.

  As shown in FIG. 12, the refrigerated warehouse 700 according to the seventh embodiment of the present invention includes the air curtain device 20 and the cooling device 30 on the region 11 side, and the air curtain device 40 and the cooling device 50 on the region 12 side. It is installed. Here, in the seventh embodiment, as shown in FIGS. 13 and 14, the air curtain devices 20 and 40 have the region 11 side (X1 side) centered on the center position (the center of the paper surface) in the X direction of the refrigerator compartment 10. Alternatively, it is configured to be movable to the region 12 side (X2 side).

  Specifically, as shown in FIGS. 12 to 14, a pair of rail members 701 are attached to the lower surface 13 a of the ceiling portion 13. The air curtain device 20 and the air curtain device 40 are attached to the lower surface 702b side of the gantry 702 in a state having a separation distance corresponding to the width of the boundary region 10b in the X direction. A pulley portion 703 is provided on the upper surface 702 a of the gantry 702 at a position corresponding to the rail member 701. And each of the some wheel 704 rotatably attached to the pulley part 703 is engaged on the corresponding rail member 701 so that rotation is possible. Further, stopper members 705 for restricting the movement of the pulley unit 703 are attached to both ends of the rail member 701. Therefore, as shown in FIGS. 12 and 13, when the gantry 702 is slid in the arrow X1 direction or the arrow X2 direction with respect to the rail member 701, the air curtain device 20 and the air curtain device 40 are moved in the arrow X1 direction. Or it is comprised so that it may move to the arrow X2 direction. Thereby, it is comprised so that the blowing position of the airflows P1 and P2 along the X direction in the internal space 10a can be changed.

  In the seventh embodiment, a rail member 701 is provided on the lower surface 13 a of the ceiling portion 13, and the air curtain device 20 and the air curtain device 40 are fixed via a movable base 702. That is, as shown in FIG. 14, the air curtain devices 20 and 40 are arranged in a region 11 in a state where the air curtain devices 20 and 40 are arranged at a height position spaced downward (in the direction of the arrow Z2) with respect to the lower surface 13 a of the ceiling portion 13 of the refrigerator compartment 10. It is comprised so that it may move to the side or area | region 12 side. Therefore, a resin seal member 710 is provided so as to close a gap between the lower surface 13a of the ceiling portion 13 of the refrigerator compartment 10 and the upper surface 702a of the mount 702 corresponding to the upper surfaces of the air curtain devices 20 and 40. .

  Further, the seal member 710 has an upper end 7a (Z1 side) fixed to the lower surface 13a of the ceiling portion 13 and a lower end 7b (Z2 side) fixed to the upper surface 702a of the mount 702. Here, the upper end 7 a is fixed to the lower surface 13 a of the ceiling portion 13 corresponding to the center position in the X direction of the refrigerator compartment 10. The resin seal member 710 is a sheet-like member whose shape can be freely changed. As a result, even if the gantry 702 is moved to any position along the X direction in which the rail member 701 extends, the intermediate portion of the seal member 710 is deformed into an S shape along the Z direction (X direction). Thus, the gap between the lower surface 13a of the ceiling portion 13 and the upper surface 702a of the mount 702 is always closed. That is, no air flow (cold air movement) occurs between the region 11 and the region 12 through the gap between the lower surface 13a of the ceiling portion 13 and the upper surface 702a of the mount 702, so the regions 11 and 12 have the temperature T1. And T2 are easily maintained.

  Thereby, for example, when the contents and the number of the articles 1 and 2 vary with the seasonal change, and the volume ratio between the area 11 and the area 12 in the refrigerator compartment 10 needs to be changed accordingly, By moving 702, the volume ratio between the region 11 and the region 12 can be changed as appropriate.

  Moreover, in 7th Embodiment, when the mount frame 702 is moved along the X direction and the volume ratio of the area | region 11 and the area | region 12 is changed, it will go to the area | region 11 side or the area | region 12 side of the air curtain apparatuses 20 and 40. The air speeds of the airflows P1 and P2 are adjusted in accordance with the travel distance (distance L1 and distance L2 described later).

  In this case, as shown in FIG. 15, in the refrigerator compartment 10, in addition to the temperature sensors 81 and 82, a position sensor 87 for detecting the position (moving position) of the gantry 702 in the X direction is provided. . As shown in FIGS. 12 and 13, the position sensor 87 is attached to the end portion on the X1 side of the Y2 side pulley portion 703 and the current position of the position sensor 87 with respect to the rail member 701 fixed to the ceiling portion 13. Is detected by the overall control unit 71 (see FIG. 15). Therefore, based on the detection result of the position sensor 87, the distance L1 (see FIG. 12) between the cooling device 30 and the air curtain device 20 and the distance L2 (see FIG. 12) between the cooling device 50 and the air curtain device 40 are respectively Configured to be grasped. The distance L1 and the distance L2 are examples of the “movement distance” in the present invention.

  For example, it is assumed that the gantry 702 is moved along the arrow X1 direction so that the region 11 is relatively small and the region 12 is relatively large. In this case, the distance L1 between the cooling device 30 and the air curtain device 20 in the region 11 is smaller than the distance L2 between the cooling device 50 and the air curtain device 40 in the region 12 (L1 <L2). Therefore, as an example, as shown in FIG. 12, the wind speed V1 of the air flow P1 blown down from the air curtain device 20 is relatively small, and the wind speed V2 of the air flow P2 blown down from the air curtain device 40 is relatively low. It is adjusted to be larger. The detection results of the temperature sensors 81 and 82 are used for capacity adjustment control of the cooling devices 30 and 50. As described above, the air velocities V1 and V2 of the airflows P1 and P2 respectively change the temperature of the region 11 to the temperature T1 according to the moving distance (distances L1 and L2) of the air curtain devices 20 and 40 toward the region 11 or the region 12 side. And the region 12 is adjusted so as to be maintained at the temperature T2.

  As another example, when distance L1 <distance L2, the wind direction of the airflow P1 from the air curtain device 20 (wind direction angle with respect to the vertical direction (Z direction)) and the wind direction of the airflow P2 from the air curtain device 40 (vertical) The wind direction angle with respect to the direction (Z direction) may be adjusted to each other. Furthermore, it is possible to maintain the region 11 at the temperature T1 and the region 12 at the temperature T2 by mutually adjusting the wind speed and direction of the air stream P1 and the wind speed and direction of the air stream P2. In addition, the other structure of the refrigerator warehouse 700 by 7th Embodiment is the same as that of the said 1st Embodiment.

  In the seventh embodiment, the following effects can be obtained.

  In the seventh embodiment, as described above, the air curtain device 20 and the air curtain device 40 are configured to be movable toward the region 11 side or the region 12 side. Thereby, even when the volume ratio (layout) between the area 11 and the area 12 in the refrigerator compartment 10 is changed, the air curtain device 20 can easily correspond to the changed volume ratio (layout). And 40 can be moved. Therefore, even when the layout arrangements of the regions 11 and 12 are changed from each other, it is possible to easily maintain the temperatures of the regions 11 and 12 together.

  Moreover, in 7th Embodiment, the air curtain apparatus 20 and the air curtain apparatus 40 can be moved to the area | region 11 side or the area | region 12 side in the height position spaced apart below with respect to the lower surface 13a of the ceiling part 13 of the refrigerator compartment 10. Configure. In this case, a seal member 710 is provided so as to close a gap between the lower surface 13a of the ceiling portion 13 of the refrigerator compartment 10 and the upper surface 702a of the mount 702 that fixes the air curtain devices 20 and 40. Thus, even when the air curtain devices 20 and 40 are moved with a gap with respect to the ceiling portion 13 of the refrigerator compartment 10, the seal member 710 is disposed so as to block the gap. Therefore, it is possible to prevent the region 11 and the region 12 from communicating with each other through this gap. That is, since air flow does not occur between the region 11 and the region 12 through this gap, the regions 11 and 12 can be easily maintained at the temperatures T1 and T2, respectively.

  In the seventh embodiment, the region 11 is set at the temperature T1 according to the distance L1 (movement distance) to the region 11 side of the air curtain device 20 and the distance L2 (movement distance) to the region 12 side of the air curtain device 40. And the wind speeds V1 and V2 of the airflow P1 and the airflow P2 are adjusted so as to maintain the region 12 at the temperature T2. Further, the region 11 is maintained at the temperature T1 and the region 12 is maintained at the temperature T2 by adjusting not only the wind speeds V1 and V2 but also the wind direction of each air curtain device. Thereby, even when the space volume ratio of each of the regions 11 and 12 is changed with the movement of the air curtain devices 20 and 40 toward the region 11 side or the region 12 side, each of the airflows P1 and P2 is changed. Since the wind speeds V1 and V2 (and / or the respective wind directions of the airflows P1 and P2) are adjusted according to the distance L1 or L2, the boundary region between the region 11 and the region 12 due to the difference in the respective spatial volumes In the vicinity of 10b, the shape of the air curtain airflow (airflows P1 and P2) can be prevented from being distorted (curved). Therefore, irrespective of the space volume ratio of each of the regions 11 and 12, the function of shutting off (insulating) by the airflows P1 and P2 can be maintained. The remaining effects of the seventh embodiment are similar to those of the aforementioned first embodiment.

(Modification of the seventh embodiment)

In the modified example of the seventh embodiment, an example in which the configuration shown in the sixth embodiment is added to the configuration of the seventh embodiment will be described. In the figure, components similar to those in the first embodiment are denoted by the same reference numerals as those in the first embodiment.

  That is, as shown in FIG. 16, the refrigerated warehouse 750 according to the modified example of the seventh embodiment is provided with a rail member 701 on the lower surface 13 a of the ceiling portion 13, and is further connected to the air curtain device 20 via a movable base 702. The air curtain device 40 is attached to the lower surface 702b side (Z2 side) of the gantry 702. Further, a shielding member 601 is provided between the air curtain devices 20 and 40. Here, the shielding member 601 has an upper end 601 a attached to the lower surface 702 b of the gantry 702. Further, the shielding member 601 is located at a position where the lower end 601b is higher than the floor surface 14 of the refrigerator compartment 10.

  Thereby, in addition to adjusting the respective wind speeds V1 and V2 of the airflows P1 and P2 according to the moving distances (distances L1 and L2) of the air curtain devices 20 and 40 toward the region 11 side or the region 12 side, Even when the wind speeds V1 and V2 of the airflows P1 and P2 are greatly different, the airflow P1 immediately after being blown down from the air curtain device 20 and the airflow immediately after being blown down from the air curtain device 40 in the boundary region 10b. P2 is configured to be able to go to the floor surface 14 without interfering with each other by the shielding member 601. That is, the role of the heat insulation wall by the air currents P1 and P2 is maintained without significantly disturbing the air current shape formed in the boundary region 10b. In addition, the other structure of the refrigerator warehouse 750 by the modification of 7th Embodiment is the same as that of the said 7th Embodiment.

  In the modification of the seventh embodiment, the following effects can be obtained.

Thereby, even when the layout arrangement of the region 11 and the region 12 is significantly changed, the heat insulating wall formed by the airflows P1 and P2 is not disturbed significantly by the shielding member 601 in the boundary region 10b. Thus, it is possible to effectively maintain the temperature of the region 11 and the region 12 together. The remaining effects of the modification of the seventh embodiment are similar to those of the aforementioned seventh embodiment.
