[0003] [Patent Document 1] Japanese Patent Publication No. 60-30638 Summary of the Invention [Problem to be solved by the invention]

[0004] The storage method of Patent Document 1 makes it possible to adjust the air composition inside (storage space) of a container placed in a storage facility such as a refrigerator, but the air temperature in the storage space only changes in conjunction with the air temperature inside the storage facility, and the temperature of the storage space cannot be appropriately controlled.

[0005] An object of the present disclosure is to appropriately control the temperature of compartmentalized storage spaces inside a storehouse. [Means for solving the problem]

[0006] The first aspect is A storage system provided in a storehouse (1) in which air in a first space (3) in a first casing (2) is cooled by a refrigeration device (10), a second casing (61) disposed inside the first space (3) and defining a second space (62) in which items are stored; an air conditioning device (50) that adjusts the composition of air supplied to the second space (62); a gas supply path (275) for supplying a first gas, the composition of which has been adjusted by the air conditioner (50), to the second space (62); and a cooling mechanism (70) provided in at least a part of the gas supply path (275) for cooling the first gas.

[0007] In the first aspect, the first gas cooled by the cooling mechanism (70) can be supplied to the second space (62). This makes it possible to control the air temperature in the second space (62) more appropriately than by regulating the air temperature in the second space (62) only by using the inside air cooled by the refrigeration device (10).

[0008] The second aspect is the first aspect, The cooling mechanism (70) cools the first gas in the gas supply path (275) by air in the first space (3).

[0009] In the second aspect, the cooling mechanism (70) can cool the first gas by transferring heat from the first gas passing through the gas supply path (275) to the cooled air in the first space (3). This makes it possible to simply cool the first gas without providing a special device in the cooling mechanism (70).

[0010] The third aspect is the first or second aspect, The cooling mechanism (70) includes a first pipe portion (70) that constitutes a part of the gas supply path (275), The first pipe portion (70) is made of a material having a higher thermal conductivity than the material of the other parts of the gas supply path (275) than the first pipe portion (70).

[0011] In the third aspect, cooling of the first gas is promoted by the cooled air in the first space (3) in the first pipe portion (70) of the gas supply path (275). In this manner, by using a part of the gas supply path (275), the first gas can be simply cooled.

[0012] The fourth aspect is the first or second aspect, The cooling mechanism (70) has a first tube portion (70) made of metal or glass that constitutes at least a part of the gas supply path (275).

[0013] In the fourth aspect, since the thermal conductivity of the first pipe portion (70) is relatively high, the first gas passing through the first pipe portion (70) can be quickly cooled.

[0014] A fifth aspect is any one of the first to fourth aspects, a gas-liquid separator (80) configured to separate a liquid flowing together with the first gas flowing in the gas supply path (275), The gas-liquid separator (80) is disposed downstream of the cooling mechanism (70) in the flow direction of the first gas, or downstream of the cooling mechanism (70) in the flow direction of the first gas.

[0015] In the fifth aspect, only the first gas can be supplied to the second space (62), and liquid passing through the gas supply path (275) can be prevented from flowing into the second space (62). This makes it possible to prevent water from splashing on the items stored in the second space (62), thereby preventing deterioration in the quality of the items.

[0016] A sixth aspect is any one of the first to fifth aspects, The air conditioning device (50) adjusts the first gas to be supplied to the second space by an adsorption / desorption system of gas molecules using zeolite or MOF (Metal-Organic Framework).

[0017] In the sixth embodiment, a nitrogen-enriched gas or air with a relatively high humidity can be supplied as the first gas to the second space (62) by a gas molecule adsorption / desorption system using zeolite.

[0018] A seventh aspect is any one of the first to sixth aspects, The first casing (2) is made of a material having a higher thermal insulation property than the second casing (61).

[0019] In the seventh aspect, it is possible to suppress an increase in the temperature of the air in the first space (3) and to promote heat transfer between the first space (3) and the second space (62). As a result, the air temperature in the second space (62) can be cooled relatively quickly by the air cooled in the first space (3).

[0020] The eighth aspect is any one of the first to seventh aspects, The second casing (61) is made of a transparent material that allows the inside of the second space (62) to be viewed.

[0021] In the eighth aspect, the items stored in the second space (62) can be seen from outside the second casing (61) without entering the second space (62).

[0022] A ninth aspect is any one of the first to eighth aspects, A plurality of the second casings (61) are disposed in the first space (3), The gas supply passage (275) a first flow path (275A) having one end connected to the air conditioning device (50); a plurality of second flow paths (275B) each having one end connected to the other end of the first flow path (275A) and the other ends connected to each of the second casings (61); The cooling mechanism (70) is provided in the first flow path (275A).

[0023] In the ninth aspect, for example, when a target stored item is to be removed, the second casing (61) in which the target stored item is stored is opened, while the other second casings (61) remain closed, thereby making it possible to suppress changes in the air composition in the second spaces (62) of the other second casings (61).

[0024] A tenth aspect of the present invention is a storage system (60) according to any one of the first to ninth aspects; a first casing (2) that defines the first space (3) in which the second casing (61) is disposed; a refrigeration device (10) for cooling the air in the first space (3); It is an in-store cooling system.

[0025] In a tenth aspect, an internal cooling system can be provided, which includes a storage system (60), a first casing (2), and a refrigeration device (10).

[0026] The eleventh aspect is the method according to the tenth aspect, A plurality of the storage systems (60) are provided in the first space (3).

[0027] In the eleventh embodiment, for example, the air in the second spaces (62) can be individually adjusted to a desired air composition. Therefore, a plurality of types of storage items with different storage conditions can be stored in one storage facility (1). [Brief description of the drawings]

Furthermore, each configuration of the embodiments, modifications, other examples, etc. described below can be combined or partially substituted within the scope in which the present invention can be implemented.

[0030] (1) Internal cooling system As shown in Fig. 1, an internal cooling system (100) of this embodiment is applied to a storage facility (1). The storage facility (1) stores items such as fresh produce (fruits, vegetables), fresh fish, meat, and other perishables, grains, or flowers. The storage facility (1) is, for example, a stationary storage facility for storing fresh produce. The internal cooling system (100) includes the storage facility (1), a refrigeration device (10), and a storage system (60).

[0031] The storage facility (1) has an internal space (3). The internal space (3) is an example of a first space (3). The storage facility (1) has a storage facility main body (2) that forms the internal space (3). The storage facility main body (2) is an example of a first casing (2). The storage facility main body (2) is provided with a heat insulating material (not shown). This provides the storage facility main body (2) with heat insulation from the air outside the storage facility.

[0032] The refrigeration system (10) cools the air (also referred to as internal air) in the internal space (3). The refrigeration system (10) will be described in detail later.

[0033] The storage system (60) has a storage unit (61) arranged to divide the interior space (3). The storage unit (61) has an internal storage space (62). The storage space (62) is an example of a second space (62). The storage system (60) has an air conditioner (50). The air conditioner (50) is a device for performing so-called controlled atmosphere (CA). The air conditioner (50) adjusts the composition of the air outside the storage facility (1).

[0034] (2) Refrigeration equipment The refrigeration system (10) has a utilization unit and a heat source unit. The utilization unit and the heat source unit are connected to each other by a communication pipe (refrigerant pipe).

[0035] The utilization unit is disposed in the interior space (3). The utilization unit includes an interior heat exchanger (29), an interior fan (30), and an expansion valve (31). The interior heat exchanger (29) cools the interior air. The interior fan (30) transports the interior air to the interior heat exchanger (29).

[0036] The heat source unit includes a compressor (25), an external heat exchanger (26), and an external fan (27). The compressor (25) compresses the sucked refrigerant and discharges it to a refrigerant pipe. The external heat exchanger (26) dissipates heat to the outside air. The external fan (27) transports the outside air to the external heat exchanger (26).

[0037] 2, the compressor (25), the external heat exchanger (26), the expansion valve (31), and the internal heat exchanger (29) are connected by piping to form a refrigerant circuit (R). When the compressor (25) is operated, the refrigerant circulates through the refrigerant circuit (R) to perform a vapor compression refrigerant cycle.

[0038] As shown in Fig. 5, the refrigeration system (10) has an inside temperature sensor (51) and an outside temperature sensor (52). The inside temperature sensor (51) detects the temperature of the inside air in the storage compartment (1). The outside temperature sensor (52) detects the temperature of the outside air outside the storage compartment (1).

[0039] As shown in Fig. 5, the refrigeration system (10) has a first control unit (C1). The first control unit (C1) includes a microprocessor, an electric circuit, and an electronic circuit. The microprocessor includes a CPU (Central Processing Unit), a memory, a communication interface, an analog input / output, and a contact input / output interface. The memory stores various programs to be executed by the CPU and data used by the programs.

[0040] The first control unit (C1) controls various devices of the refrigeration system (10). Specifically, the first control unit (C1) controls the rotation speed of the compressor (25), the rotation speed of the internal fan (30), the rotation speed of the external fan (27), the opening of the expansion valve (31), etc. Measurement values ​​of the internal temperature sensor (51) and the external temperature sensor (52) are input to the first control unit (C1).

[0041] (3) Storage system As shown in FIG. 1, the storage system (60) is provided in a storage facility (1) in which the air in an internal space (3) of a storage facility body (2) is cooled by a refrigeration device (10).

[0042] The storage system (60) includes a storage unit (61), an air conditioner (50), a gas supply pipe (275), and a cooling mechanism (70).

[0043] (3-1) Containment Unit As shown in FIGS. 1 and 3 , the storage unit (61) is disposed inside the interior space (3). The storage unit (61) stores storage items. The storage unit (61) is formed in a box shape. The storage unit (61) is an example of a second casing (61). The storage unit (61) defines a storage space (62) therein. The storage items are kept in the storage space (62). The storage space (62) is an example of a second space (62).

[0044] The storage unit (61) has a transparent material that allows the inside of the storage space (62) to be seen from the outside. Specifically, each surface of the storage unit (61) is formed of a rectangular frame (63) and a resin sheet (64) that covers the inner frame of the frame (63). The storage unit (61) is formed so that no gaps are formed between the surfaces. This maintains the airtightness of the storage space (62). The top surface of the storage unit (61) is configured so as to be removable from the storage unit (61). By removing the top surface of the storage unit (61), fruits and vegetables can be stored in and removed from the storage unit (61). As described above, the storage unit (61) is formed of the resin sheet (64) and the frame (63), and therefore has a lower thermal insulation property than the storage unit main body (2) of the storage unit (1). In other words, the storage unit main body (2) is formed of a material that has a higher thermal insulation property than the storage unit (61).

[0045] A gas supply pipe (275) and a ventilation exhaust pipe (280) are connected to the accommodation unit (61). The gas supply pipe (275) will be described later. The ventilation exhaust pipe (280) exhausts air from within the accommodation space (62) to the outside. A ventilation exhaust valve (151) is provided in the ventilation exhaust pipe (280). The ventilation exhaust valve (151) is an on-off valve formed of a solenoid valve.

[0046] The containing unit (61) is provided therein with an internal unit temperature sensor (55), an internal unit humidity sensor (56), and an oxygen sensor (57). These sensors will be described later.

[0047] (3-2) Air conditioning equipment As shown in Fig. 4, the air conditioner (50) adjusts the composition of outside air and supplies the adjusted gas to the accommodation space (62).

The air conditioner (50) includes a filter unit (220), a main unit (200), a gas supply pipe (275), a gas exhaust pipe (276), and a second control section (C2).

[0048] The air conditioner (50) adjusts the conditioned gas to be supplied to the storage space (62) by a gas molecule adsorption / desorption system using zeolite. Specifically, the air conditioner (50) is a gas separation device of the so-called VPSA (Vacuum Pressure Swing Adsorption) type. The air conditioner (50) separates the outside air (air) to be treated into a nitrogen-rich gas having a higher nitrogen concentration and a lower oxygen concentration than the air, and an oxygen-rich gas having a lower nitrogen concentration and a higher oxygen concentration than the air.

The unit case (201) houses an inlet pipe (242), a suction pipe (243), a first gas pipe (244), and a second gas pipe (245).

[0052] (3-2-3) Air pump The air pump (231) includes a pressurized pump (231a), a reduced pressure pump (231b), and a drive motor (231c). The pressurized pump (231a) and the reduced pressure pump (231b) each suck in and discharge air. The pressurized pump (231a) and the reduced pressure pump (231b) are connected to a drive shaft of a single drive motor (231c). In other words, the pressurized pump (231a) and the reduced pressure pump (231b) are driven by the single drive motor (231c).

[0053] The other end of the outside air pipe (241) is connected to the suction port of the pressurizing pump (231a). One end of an introduction pipe (242) is connected to the discharge port of the pressurizing pump (231a). The pressurizing pump (231a) supplies the air to be treated, sucked in through the outside air pipe (241), to the first adsorption column (234) and the second adsorption column (235) through the introduction pipe (242).

[0054] A suction pipe (243) is connected to the suction port of the decompression-side pump (231b). A first gas pipe (244) is connected to the discharge port of the decompression-side pump (231b). The decompression-side pump (231b) discharges gas sucked from the first adsorption column (234) and the second adsorption column (235) through the suction pipe (243) to the first gas pipe (244).

[0055] (3-2-4) Introduction pipe The inlet pipe (242) is a pipe that guides the air to be treated discharged from the pressurizing pump (231a) to the first adsorption column (234) and the second adsorption column (235).

The other end of the inlet pipe (242) branches into two branch pipes, one of which is connected to the first selector valve (232) and the other of which is connected to the second selector valve (233).

[0056] (3-2-5) Suction tube The suction pipe (243) is a pipe that guides the gas flowing out from the first adsorption column (234) and the second adsorption column (235) to the pressure reduction pump (231b). One end of the suction pipe (243) is connected to the suction port of the pressure reduction pump (231b). The other end of the suction pipe (243) branches into two branch pipes, one of which is connected to the first switch valve (232) and the other of which is connected to the second switch valve (233).

[0057] (3-2-6) First Gas Pipe The first gas pipe (244) is a pipe through which the nitrogen-enriched gas discharged from the pressure reduction pump (231b) flows. One end of the first gas pipe (244) is connected to a discharge port of the pressure reduction pump (231b). The other end of the first gas pipe (244) is connected to a gas supply pipe (275).

[0058] The first gas pipe (244) is provided with a check valve (264). The check valve (264) allows gas to flow only in a direction from one end to the other end of the first gas pipe (244) and blocks gas from flowing in the opposite direction.

[0059] (3-2-7) Switching valve Each of the first switching valve (232) and the second switching valve (233) is a switching valve having three ports. Each of the first switching valve (232) and the second switching valve (233) is configured to be switched between a first state (a state shown by a solid line in FIG. 4) in which the first port communicates with the second port and is cut off from the third port, and a second state (a state shown by a dashed line in FIG. 4) in which the first port communicates with the third port and is cut off from the second port.

[0060] The first switch valve (232) has a first port connected to one end of the first adsorption column (234). The first switch valve (232) has a second port connected to a branch pipe of the introduction pipe (242) and a third port connected to a branch pipe of the suction pipe (243). The first switch valve (232) switches the first adsorption column (234) between a state where it is connected to the pressurization pump (231a) and a state where it is connected to the depressurization pump (231b).

[0061] The second selector valve (233) has a first port connected to one end of the second adsorption column (235). A branch pipe of the inlet pipe (242) is connected to a second port of the second selector valve (233), and a branch pipe of the suction pipe (243) is connected to a third port of the second selector valve (233). The second selector valve (233) switches the second adsorption column (235) between a state where it is connected to the pressurization pump (231a) and a state where it is connected to the depressurization pump (231b).

[0062] (3-2-8) Adsorption cylinder The first adsorption column (234) and the second adsorption column (235) each include a cylindrical container with both ends closed and an adsorbent filled in the container. The adsorption columns (234, 235) use the adsorbent to separate the air to be treated (outside the chamber air in this embodiment) into an oxygen-enriched gas and a nitrogen-enriched gas.

[0063] The adsorbent filled in the adsorption columns (234, 235) has the property of adsorbing nitrogen and water (water vapor) in the air to be treated when the pressure is higher than atmospheric pressure, and desorbing nitrogen and water when the pressure is lower than atmospheric pressure. One example of an adsorbent having such a property is porous zeolite having pores with a pore size smaller than the molecular diameter of a nitrogen molecule (3.0 angstroms) and larger than the molecular diameter of an oxygen molecule (2.8 angstroms).

[0064] (3-2-9) Second Gas Pipe The second gas pipe (245) includes a trunk pipe (246), a first branch pipe (247a), a second branch pipe (247b), a supply branch pipe (248a), and a discharge branch pipe (248b). The second gas pipe (245) is provided with an oxygen selector valve (249).

[0065] The first branch pipe (247a) is a pipe that connects the other end of the first adsorption cylinder (234) to one end of the trunk pipe (246). The second branch pipe (247b) is a pipe that connects the other end of the second adsorption cylinder (235) to one end of the trunk pipe (246). The first branch pipe (247a) and the second branch pipe (247b) are each provided with a check valve (261). Each check valve (261) allows air to flow in the outgoing direction from the corresponding adsorption cylinder (234, 235) and restricts air to flow in the opposite direction.

[0066] As described above, the first branch pipe (247a) and the second branch pipe (247b) are connected to one end of the trunk pipe (246). The other end of the trunk pipe (246) is connected to the oxygen selector valve (249). The trunk pipe (246) is provided with, in this order from one end to the other, an orifice (263) and a check valve (262). The check valve (262) allows air to flow from one end of the trunk pipe (246) to the other end and restricts air from flowing in the opposite direction.

[0067] The supply branch pipe (248a) has one end connected to the oxygen switch valve (249) and the other end connected to one end of the gas supply pipe (275). The supply branch pipe (248a) constitutes a supply passage for introducing the oxygen-rich gas into the accommodation unit (61). The discharge branch pipe (248b) has one end connected to the oxygen switch valve (249) and the other end connected to one end of the gas discharge pipe (276). The discharge branch pipe (248b) constitutes a discharge passage for discharging the oxygen-rich gas to the outside of the unit case (201).

[0068] The oxygen selector valve (249) is a three-way valve. As described above, the trunk pipe (246), the supply branch pipe (248a), and the discharge branch pipe (248b) are connected to the oxygen selector valve (249). The oxygen selector valve (249) is switchable between a first state in which the trunk pipe (246) communicates with the supply branch pipe (248a) and restricts the flow from the discharge branch pipe (248b) and a second state in which the trunk pipe (246) communicates with the discharge branch pipe (248b) and restricts the flow from the supply branch pipe (248a).

[0069] The oxygen selector valve (249) is a switching mechanism that switches the second gas pipe (245) between an introduction state and a discharge state. When the oxygen selector valve (249) is in the first state, the second gas pipe (245) is in the introduction state, and the oxygen-rich gas is introduced into the housing unit (61) through the supply branch pipe (248a). When the oxygen selector valve (249) is in the second state, the second gas pipe (245) is in the discharge state, and the oxygen-rich gas is discharged to the outside of the unit case (201) through the discharge branch pipe (248b).

[0070] (3-2-10) Purge pipe A purge pipe (250) is connected to each of the first branch pipe (247a) and the second branch pipe (247b) of the second gas pipe (245). One end of the purge pipe (250) is connected to the first branch pipe (247a) and the other end is connected to the second branch pipe (247b). One end of the purge pipe (250) is connected to the first branch pipe (247a) between the first adsorption column (234) and the check valve (261). The other end of the purge pipe (250) is connected to the second branch pipe (247b) between the second adsorption column (235) and the check valve (261).

[0071] The purge pipe (250) is provided with a purge valve (251). The purge valve (251) is an on-off valve formed of a solenoid valve. The purge valve (251) is opened when equalizing the pressure in the first adsorption column (234) and the second adsorption column (235). In addition, an orifice (252) is provided on each side of the purge valve (251) in the purge pipe (250).

[0072] (3-2-11) Exhaust connection pipe An exhaust connection pipe (271) is connected to the first gas pipe (244). One end of the exhaust connection pipe (271) is connected to the first gas pipe (244) and the other end is connected to the second gas pipe (245). One end of the exhaust connection pipe (271) is connected to the first gas pipe (244) between the pressure reducing pump (231b) and the check valve (264). The other end of the exhaust connection pipe (271) is connected to one end of the gas exhaust pipe (276).

[0073] The exhaust connection pipe (271) is provided with a gas exhaust valve (272). The gas exhaust valve (272) is an on-off valve formed of a solenoid valve. When the gas exhaust valve (272) is opened, the nitrogen-enriched gas flowing through the first gas pipe (244) is exhausted to the outside of the unit case (201). The gas exhaust valve (272) is a flow rate adjusting mechanism that adjusts the flow rate of the nitrogen-enriched gas flowing through the exhaust connection pipe (271). By adjusting the open and closed times of the gas exhaust valve (272), the flow rate of the nitrogen-enriched gas exhausted to the outside of the unit case (201) through the exhaust connection pipe (271) changes.

[0074] (3-2-12) Gas supply pipe The gas supply pipe (275) supplies the regulated gas to the storage unit (61). As described above, one end of the gas supply pipe (275) is connected to the first gas pipe (244) and the supply side branch pipe (248a) of the second gas pipe (245). The gas supply pipe (275) extends to the outside of the unit case (201). The other end of the gas supply pipe (275) is connected to the inside of the storage unit (61) arranged in the internal space (3). In this way, the regulated gas flows into the storage space (62). The gas supply pipe (275) is an example of a gas supply path (275).

[0075] A gas supply valve (273) is provided on the gas supply pipe (275). The gas supply valve (273) is an on-off valve formed of a solenoid valve.

[0076] (3-2-13) Gas exhaust pipe As described above, one end of the gas exhaust pipe (276) is connected to the exhaust branch pipe (248b) of the second gas pipe (245) and the exhaust connection pipe (271). The gas exhaust pipe (276) extends to the outside of the unit case (201). The other end of the gas exhaust pipe (276) opens to the outside of the unit case (201). The gas exhaust pipe (276) is a pipe for exhausting the gas that has flowed in from the one end of the gas exhaust pipe (276) to the outside of the unit case (201).

[0077] (3-2-14) Bypass pipe A bypass connection pipe (255) is connected to the inlet pipe (242). The bypass connection pipe (255) is a pipe for supplying the outside air to the storage space (62) of the storage unit (61) by bypassing the first adsorption column (234) and the second adsorption column (235). One end of the bypass connection pipe (255) is connected between the branch point of the inlet pipe (242) and the pressurizing pump (231a). The other end of the bypass connection pipe (255) is connected to the first gas pipe (244) downstream of the check valve (264).

[0078] The bypass connecting pipe (255) is provided with a bypass on-off valve (256). The bypass on-off valve (256) is an on-off valve formed of a solenoid valve. The bypass on-off valve (256) is opened when the outside air discharged by the pressurizing pump (231a) is supplied to the storage space (62) without changing the composition of the outside air.

[0079] (3-2-15) Sensor The air conditioner (50) has an in-unit temperature sensor (55), an in-unit humidity sensor (56), and an oxygen sensor (57). The in-unit temperature sensor (55) detects the air temperature in the accommodation space (62). The in-unit humidity sensor (56) detects the humidity in the accommodation space (62). The oxygen sensor (57) detects the oxygen concentration in the accommodation space (62). The in-unit temperature sensor (55) is disposed approximately in the center of the accommodation space (62).

[0080] (3-2-16) Second Control Section The second control unit (C2) includes a microprocessor, an electric circuit, and an electronic circuit. The microprocessor includes a CPU (Central Processing Unit), a memory, a communication interface, an analog input / output, and a contact input / output interface. The memory stores various programs executed by the CPU and data used by the programs.

[0081] 5, the second control unit (C2) receives measurement values ​​from the unit internal temperature sensor (55), the unit internal humidity sensor (56), and the oxygen sensor (57). The second control unit (C2) controls various devices of the air conditioner (50). Specifically, the second control unit (C2) controls the air pump (231), the first switching valve (232), the second switching valve (233), the oxygen switching valve (249), the ventilation exhaust valve (151), the purge valve (251), the bypass on-off valve (256), the gas exhaust valve (272), and the gas supply valve (273) of the air conditioner (50).

[0082] The second control section (C2) receives measurement values ​​detected by the unit internal temperature sensor (55), the unit internal humidity sensor (56), and the oxygen sensor (57).

[0083] (4) Cooling mechanism As shown in FIG. 1 , the air conditioning device (50) has a cooling mechanism (70). The cooling mechanism (70) cools the conditioned gas in the gas supply pipe (275) by using air in the interior space (3). The cooling mechanism (70) is provided in the gas supply pipe (275). In this embodiment, the cooling mechanism (70) is a first pipe section (70) constituting a part of the gas supply pipe (275). The first pipe section (70) is made of a material having a higher thermal conductivity than the other parts of the gas supply pipe (275) other than the first pipe section (70).

[0084] Specifically, the gas supply pipe (275) has a first pipe portion (70) made of metal and a second pipe portion (90) made of resin. The second pipe portion (90) and the first pipe portion (70) are connected in this order from the air conditioning device (50) toward the storage unit (61), so that the conditioned gas flowing into the gas supply pipe (275) flows through the second pipe portion (90) and the first pipe portion (70) in this order.

[0085] A part or the whole of the first pipe section (70) is disposed in the internal space (3). The air in the internal space (3) exchanges heat with the conditioned gas in the first pipe section (70) through the first pipe section (70). That is, the first pipe section (70) is cooled by the air in the internal space (3) cooled by the refrigeration device (10), and thus the conditioned gas flowing through the first pipe section (70) is cooled. The longer the first pipe section (70) is, the closer the conditioned gas flowing through the first pipe section (70) is to the air temperature in the internal space (3). In addition, the thinner the thickness of the first pipe section (70) (i.e., the distance between the inner surface and the outer surface in the radial direction of the first pipe section (70) is, the more easily the air temperature in the internal space (3) is propagated into the first pipe section (70), and therefore the more quickly the conditioned gas flowing through the first pipe section (70) is cooled.

[0086] (5) Gas-liquid separator As shown in Figures 1 and 6, the storage system (60) includes a gas-liquid separator (80). The gas-liquid separator (80) separates liquid flowing together with the conditioned gas flowing through the gas supply pipe (275). For example, water mixes with the conditioned gas due to condensation caused by cooling of the air and flows through the gas supply pipe (275) toward the storage unit (61). The gas-liquid separator (80) separates and discharges such water from the conditioned gas before it flows into the storage unit (61).

[0087] Specifically, the gas-liquid separator (80) is disposed downstream in the flow direction of the regulated gas in the first pipe section (70) of the gas supply pipe (275). Here, "downstream" means a position downstream of the center position of the length between the upstream end and the downstream end of the first pipe section (70). In other words, the gas-liquid separator (80) is provided at a position in the first pipe section (70) closer to the containing unit (61) than the second pipe section (90).

[0088] The gas-liquid separator (80) is formed in a vertically long cylindrical shape with a closed lower end. An inlet end (81) and an outlet end (82) are formed on the side of the gas-liquid separator (80). The inlet end (81) and the outlet end (82) are connected to the first pipe portion (70). The inlet end (81) is disposed upstream of the outlet end (82) in the flow direction of the adjusted gas. A drain pipe (83) is connected to the lower end of the gas-liquid separator (80). Water separated in the gas-liquid separator (80) flows into the drain pipe (83). The water flowing through the drain pipe (83) flows out into a reservoir (not shown).

[0089] (6) Operation of air conditioning equipment The air conditioner (50) of this embodiment performs an oxygen concentration reduction operation and an oxygen supply operation. The oxygen concentration reduction operation is an operation for reducing the oxygen concentration of the air in the storage space (62). The oxygen supply operation is an operation for increasing the oxygen concentration of the air in the storage space (62).

[0090] The air conditioning device (50) separates the outside air into a nitrogen-enriched gas (first gas) and an oxygen-enriched gas (second gas) by alternately and repeatedly performing a first operation and a second operation. The air conditioning device (50) alternates between the first operation and the second operation for a predetermined switching time (e.g., 14 seconds). The second control unit (C2) controls the first switching valve (232) and the second switching valve (233) so that the first operation and the second operation are alternately performed.

[0091] (6-1) 1st action 7 and 9, in the first operation, the first selector valve (232) is set to the first state, and the second selector valve (233) is set to the second state. In addition, in the first operation, the purge valve (251) and the bypass on-off valve (256) are held in a closed state. In the first operation, the air pump (231) is operated to perform an adsorption operation for the first adsorption tube (234) and a desorption operation for the second adsorption tube (235).

[0092] The pressurizing pump (231a) draws in outside air (atmosphere) through the outside air pipe (241), pressurizes the air, and supplies the pressurized outside air to the first adsorption column (234). In the first adsorption column (234), nitrogen and water (water vapor) contained in the supplied outside air are adsorbed by an adsorbent. As a result, the first adsorption column (234) generates an oxygen-enriched gas having a lower nitrogen concentration and a higher oxygen concentration than the outside air. The oxygen-enriched gas flows out of the first adsorption column (234) into a first branch pipe (247a) of the second gas pipe (245).

[0093] On the other hand, the decompression-side pump (231b) draws gas from the second adsorption column (235). In the second adsorption column (235), the internal pressure decreases, causing nitrogen and water to desorb from the adsorbent. As a result, a nitrogen-rich gas having a higher nitrogen concentration and a lower oxygen concentration than the air outside the chamber is generated in the second adsorption column (235). The nitrogen-rich gas flows from the second adsorption column (235) into the suction pipe (243) and is sucked into the decompression-side pump (231b). The decompression-side pump (231b) pressurizes the sucked nitrogen-rich gas and discharges it into the first gas pipe (244).

[0094] (6-2)Second operation 8 and 10, in the second operation, the first switching valve (232) is set to the second state, and the second switching valve (233) is set to the first state. In addition, in the second operation, the purge valve (251) and the bypass on-off valve (256) are held in a closed state. In the second operation, the air pump (231) is operated to perform a desorption operation for the first adsorption tube (234) and an adsorption operation for the second adsorption tube (235).

[0095] The pressurizing pump (231a) draws in outside air (atmosphere) through the outside air pipe (241), pressurizes the air, and supplies the pressurized outside air to the second adsorption column (235). In the second adsorption column (235), nitrogen and water (water vapor) contained in the supplied outside air are adsorbed by an adsorbent. As a result, the second adsorption column (235) generates an oxygen-enriched gas having a lower nitrogen concentration and a higher oxygen concentration than the outside air. The oxygen-enriched gas flows out of the second adsorption column (235) into the second branch pipe (247b) of the second gas pipe (245).

[0096] On the other hand, the decompression-side pump (231b) sucks gas from the first adsorption column (234). In the first adsorption column (234), the internal pressure decreases, causing nitrogen and water to desorb from the adsorbent. As a result, a nitrogen-rich gas having a higher nitrogen concentration and a lower oxygen concentration than the outside air is generated in the first adsorption column (234). The nitrogen-rich gas flows from the first adsorption column (234) into the suction pipe (243) and is sucked into the decompression-side pump (231b). The decompression-side pump (231b) pressurizes the sucked nitrogen-rich gas and discharges it into the first gas pipe (244).

[0097] (6-3) Reduced oxygen concentration operation The oxygen concentration reducing operation is an operation in which the oxygen concentration of the air in the accommodation space (62) is reduced by supplying nitrogen-rich gas to the accommodation space (62).

[0098] 7 and 8, in the oxygen concentration reducing operation, the gas supply valve (273) is held in an open state, and the gas exhaust valve (272) is held in a closed state. In addition, in the oxygen concentration reducing operation, the oxygen selector valve (249) is set to the second state. As a result, the trunk pipe (246) communicates with the exhaust branch pipe (248b), and the second gas pipe (245) is in the exhaust state.

[0099] In the oxygen concentration reducing operation, the nitrogen-rich gas discharged from the pressure reducing pump (231b) to the first gas pipe (244) flows into the accommodation unit (61) through the gas supply pipe (275). On the other hand, the oxygen-rich gas flowing from the first adsorption column (234) or the second adsorption column (235) to the second gas pipe (245) passes through the trunk pipe (246) and the discharge side branch pipe (248b) in this order, and then flows out of the unit case (201) through the gas discharge pipe (276).

[0100] In the oxygen concentration reducing operation, the ventilation exhaust valve (151) is held open, and the air in the accommodation space (62) flows out to the outside of the accommodation unit (61) through the ventilation exhaust pipe (280). Therefore, the air in the accommodation space (62) is gradually replaced by nitrogen-rich gas, and the oxygen concentration of the air in the accommodation space (62) gradually decreases.

[0101] (6-4) Oxygen supply operation The oxygen supply operation is an operation for increasing the oxygen concentration of the air in the accommodation space (62) by supplying an oxygen-enriched gas to the accommodation space (62).

[0102] 9 and 10, in the oxygen supply operation, the gas supply valve (273) is held open, and the gas exhaust valve (272) is held open or opened / closed. In addition, in the oxygen supply operation, the oxygen selector valve (249) is set to the first state. As a result, the trunk pipe (246) communicates with the supply-side branch pipe (248a), and the second gas pipe (245) is in the introducing state.

[0103] In the oxygen supply operation, a part of the nitrogen-rich gas discharged from the pressure reducing pump (231b) to the first gas pipe (244) passes through the exhaust connection pipe (271) and the gas exhaust pipe (276) in this order to flow out of the first casing (2), and the remainder passes through the gas supply pipe (275) to flow into the storage unit (61). On the other hand, the oxygen-rich gas flowing from the first adsorption column (234) or the second adsorption column (235) to the second gas pipe (245) passes through the trunk pipe (246) and the supply side branch pipe (248a) in this order, and then flows into the gas supply pipe (275) and into the storage unit (61). In this way, in the oxygen supply operation, a part of the nitrogen-rich gas and the entire oxygen-rich gas are supplied to the storage space (62).

[0104] In the oxygen supply operation, the ventilation exhaust valve (151) is held open, and the air in the storage space (62) flows out of the storage space (62) through the ventilation exhaust pipe (280). Therefore, the air in the storage space (62) is gradually replaced by oxygen-enriched gas, and the oxygen concentration of the air in the storage space (62) gradually increases.

[0105] (7) Features (7-1) Feature 1 The storage system (60) of this embodiment is provided in a storage facility (1) in which the air in the interior space (3) in the storage facility body (2) is cooled by the refrigeration device (10). The storage system (60) is provided with a storage unit (61) arranged inside the interior space (3) and forming a storage space (62) in which an item is stored, an air conditioning device (50) that adjusts the composition of air to be supplied to the storage space (62), a gas supply pipe (275) that supplies a first gas, the composition of which has been adjusted by the air conditioning device (50), to the storage space (62), and a cooling mechanism (70) that is provided in a part of the gas supply pipe (275) and cools the adjusted gas (first gas).

[0106] In the present embodiment, the cooling mechanism (70) can supply the cooled and conditioned gas to the storage space (62). This allows the temperature of the air in the storage space (62) to be controlled to a desired temperature, as compared to cooling the air in the storage space (62) only by the air in the interior space (3) cooled by the refrigeration device (10).

[0107] (7-2) Feature 2 The cooling mechanism (70) of the present embodiment cools the conditioned gas (first gas) in the gas supply pipe (275) by the air in the internal space (3). The (cooling) heat of the air in the internal space (3) cooled by the cooling mechanism (70) is transferred to the first gas in the gas supply pipe (275), thereby cooling the first gas. This eliminates the need to provide a special device in the cooling mechanism (70), and allows the first gas to be cooled easily. In addition, the number of parts and manufacturing costs of the cooling mechanism (70) can be reduced.

[0108] (7-3) Feature 3 The cooling mechanism (70) of the present embodiment has a first pipe section (70) constituting a part of the gas supply pipe (275). The first pipe section (70) is made of a material having a higher thermal conductivity than the other parts of the gas supply pipe (275) other than the first pipe section (70). This promotes cooling of the first gas in the first pipe section (70) by the cooled air in the internal space (3). In this manner, by using a part of the gas supply path (275), the first gas can be easily cooled.

[0109] (7-4) Feature 4 The cooling mechanism (70) of the present embodiment has a first pipe portion (70) made of metal that constitutes at least a part of the gas supply pipe (275). A metal pipe has relatively high thermal conductivity between the outside and inside of the pipe, and therefore, the cooled inside air can promote cooling of the first gas in the first pipe portion (70).

[0110] (7-5) Feature 5 The cooling mechanism (70) of the present embodiment further includes a gas-liquid separator (80) that separates the first gas and liquid flowing through the gas supply pipe (275). The gas-liquid separator (80) is disposed downstream in the flow direction of the first gas in the cooling mechanism (70).

[0111] This makes it possible to prevent water generated in the gas supply pipe (275) as a result of the first gas being cooled from flowing into the storage space (62), thereby preventing the stored items in the storage space (62) from getting wet and thus preventing deterioration in the quality of the stored items.

[0112] (7-6) Feature 6 The air conditioner (50) of the present embodiment uses a zeolite-based adsorption / desorption system for gas molecules to adjust the first gas to be supplied to the storage space (62). The zeolite-based adsorption / desorption system for gas molecules can supply nitrogen-enriched gas or air with a relatively high humidity as the first gas to the storage space (62).

[0113] (7-7) Feature 7 The storage body (2) of this embodiment is made of a material with higher thermal insulation than the storage unit (61). Since the storage body (2) is made of a material with relatively high thermal insulation, heat transfer between the air inside the storage body (2) and the air outside is suppressed. This not only suppresses an increase in temperature of the air inside the storage body (2) cooled by the refrigeration device (10), but also allows the air temperature inside the storage space (62) to be lowered relatively quickly because the storage space (62) and the interior space (3) are only separated by a resin sheet.

[0114] (7-8) Feature 8 The storage unit (61) of this embodiment is made of a transparent material that allows the inside of the storage space (62) to be visually observed, thereby allowing the state of the stored items in the storage space (62) to be visually observed from outside the storage unit (61).

[0115] (8) Variations Hereinafter, configurations different from the interior cooling system or storage system of the above-described embodiment will be described.

[0116] (8-1) Variation 1 As shown in FIG. 11, the storage system (60) of the first modification has a plurality of storage units (61) arranged in the interior space (3). The gas supply pipe (275) of the storage system (60) has a first flow path (275A) and a plurality of second flow paths (275B). The gas supply pipe (275) is formed so as to branch from the first flow path (275A) to the plurality of second flow paths (275B). Specifically, one end of the first flow path (275A) is connected to the air conditioning device (50). One end of the second flow path (275B) is connected to the other end of the first flow path (275A) and is connected to each of the plurality of storage units (61).

[0117] The first flow path (275A) is provided with a first pipe section (70). The first pipe section (70) is provided downstream of the first flow path (275A). The downstream section is a position downstream of the center between the upstream end and the downstream end of the first flow path (275A). The first pipe section (70) may be provided in all of the first flow paths (275A) arranged in the interior space (3).

[0118] In this way, since the storage system (60) of the first modification has a plurality of storage units (61), the plurality of storage units (61) can be opened and closed individually. As a result, when, for example, a specific stored item is to be removed from the storage facility (1), only the storage unit (61) in which the target stored item is stored needs to be opened, and the other storage units (61) are kept closed. In this way, even if one storage unit (61) is opened or closed, changes in the air composition in the storage space (62) of the other storage units (61) can be suppressed, and deterioration in the freshness and quality of the stored items stored in the other storage units (61) can be suppressed.

[0119] Therefore, for example, multiple types of storage items can be stored in one storage facility (1), and it is not necessary to use one storage facility (1) for one type of storage item. Therefore, for example, if there is free space in the storage facility (1) in which the storage items are stored, that space can be used to store other types of storage items, and the space in the storage facility (1) can be used effectively.

[0120] (8-2) Variation 2 12, in the interior cooling system (100) of the second modification, a plurality of storage systems (60) are arranged in the interior space (3). The storage system (60) of the second modification includes one air conditioner (50) and one storage unit (61). In other words, one storage unit (61) and one air conditioner (50) are paired in the interior space (3).

[0121] In this way, since the internal cooling system (100) of the second modification includes multiple storage systems (60), it is possible to adjust the air to a different composition for each storage space (62). This allows multiple types of storage items with different storage conditions to be stored in one storage facility (1). Specifically, since one air conditioning device (50) is connected to one storage unit (61), by individually controlling the multiple air conditioning devices (50), it is possible to adjust the air in each storage space (62) to a composition suitable for each storage item, even if there are multiple types of storage items with different optimal air compositions for storage.

[0122] (9) Other embodiments The above embodiment and each of the modified examples may be configured as follows.

[0123] The cooling mechanism (70) may be provided in the entire gas supply pipe (275). Specifically, the entire gas supply pipe (275) may be formed of the first pipe section (70).

[0124] The first tube portion (70) may be made of a metal such as copper, aluminum, or iron. The first tube portion (70) may be made of a material having a relatively high thermal conductivity, and may be made of glass. The second tube portion (90) may be made of a resin such as a urethane resin. The second tube portion (90) may be made of a material having a lower thermal conductivity than the first tube portion (70), and is not limited to being made of resin.

[0125] The gas-liquid separator (80) may be disposed downstream of the cooling mechanism (70) in the flow direction of the first gas. In other words, the gas-liquid separator (80) may be disposed in the gas supply pipe (275) between the downstream end of the first pipe section (70) and the containing unit (61).

[0126] The air conditioner (50) may be any system that adsorbs and desorbs gas molecules using zeolite, and may be of a pressure swing adsorption (PSA) type. The air conditioner (50) may also be of a system that adsorbs and desorbs gas molecules using a metal-organic framework.

[0127] The cooling mechanism (70) is not limited to a mechanism that uses air in the interior space (3) as long as it can cool the first gas in the gas supply pipe (275). For example, the cooling mechanism (70) may have a predetermined heat medium such as a refrigerant, water, or brine. The first gas in the gas supply pipe (275) is cooled by exchanging heat with the cooled heat medium.

[0128] The containing unit (61) may be any type that allows the interior to be visually confirmed, and may be made of, for example, a transparent acrylic plate.

[0129] In the first modification, one air conditioner (50) may be directly connected to each of the plurality of storage units (61) without passing through the second flow path (275B). In this case, the first flow path (275A) of the gas supply pipe (275) is connected to the air conditioners (50) for the number of storage units (61), and the conditioned gas is supplied directly from the one air conditioner (50) to each storage unit (61).

[0130] In the second variation, each storage system (60) may be connected to a plurality of storage units (61).

[0131] In the embodiment and the first modification, the main unit (200) of the air conditioning device (50) may be installed inside the storage facility (1). In the second modification, the main unit (200) of the air conditioning device (50) may be installed outside the storage facility (1).

[0132] Although the embodiments and modifications have been described above, it will be understood that various modifications of form and details are possible without departing from the spirit and scope of the claims. Furthermore, the above embodiments and modifications may be appropriately combined or substituted as long as the functions of the subject of this disclosure are not impaired. The descriptions "first", "second", ... described above are used to distinguish the words to which these descriptions are attached, and do not limit the number or order of the words.
