Description

[Technical Field]

[0001] The technology of the present disclosure relates to an environment creating device. [Background technology]

[0002] For example, the environment creating device disclosed in Patent Document 1 includes a housing that separates a test chamber containing a cooling coil and a machine chamber located below the test chamber and containing a compressor, a heat source coil, etc. In the environment creating device, outside air taken into the machine chamber is heated by the heat source coil, and the air in the test chamber is cooled by the cooling coil. In this way, the inside of the test chamber is maintained at a desired temperature. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 62-25844 Summary of the Invention [Problem to be solved by the invention]

[0004] However, there is a demand for reducing the installation space required for an environment creating device such as that described in Patent Document 1. In other words, the environment creating device requires that the air heated by the heat source coil be exhausted from the machine room. For example, if the environment creating device is installed near a wall, the housing must be installed away from the wall to ensure sufficient space for exhaust. Therefore, the installation space required for the environment creating device is actually larger than the size of the housing.

[0005] The technology of the present disclosure has been made in consideration of the above circumstances, and its purpose is to provide an environment creating device that can reduce the required installation space while still ensuring exhaust space. [Means for solving the problem]

[0006] The environment creating device of the present disclosure includes a first housing, a second housing, and an exhaust unit. The first housing has an item chamber for storing target items, and a machine chamber located below the item chamber and accommodating at least a portion of a refrigerator for cooling the target items in the item chamber. The second housing has an electrical equipment chamber for accommodating electrical components, and is provided in contact with a first side plate of the first housing. The exhaust unit exhausts air from the machine chamber. A second back plate of the second housing is located forward of the first back plate of the first housing. The exhaust unit exhausts air into a first space facing a surface of the second back plate.

[0007] In the above configuration, the refrigerator creates a desired environmental condition in the goods compartment of the first housing. Specifically, air in the machinery compartment of the first housing is heated by, for example, a radiator of the refrigerator, and air in the goods compartment of the first housing is cooled by, for example, an evaporator of the refrigerator. The refrigerator is controlled by electrical equipment housed in the electrical equipment compartment of the second housing. This adjusts the temperature of the goods in the goods compartment to the desired temperature.

[0008] Meanwhile, the air in the machine room heated by the radiator is exhausted by the exhaust unit. Here, the second back panel of the second housing is located forward of the first back panel of the first housing. Therefore, even if the first housing is installed with the first back panel of the first housing close to the wall of the installation location, a first space is formed between the second housing and the wall. The air in the machine room is exhausted into the first space by the exhaust unit. The exhausted air flows upward through the first space. In this way, the first space is secured as an exhaust space even if the first housing is not installed away from the wall. Therefore, the required installation space can be reduced while still securing the exhaust space.

[0009] A second bottom plate of the second housing may be located higher than a first bottom plate of the first housing.

[0010] In the above configuration, the second bottom plate of the second housing is positioned higher than the first bottom plate of the first housing, forming a space below the second housing. In other words, a predetermined space is formed between the second housing and, for example, the floor. Therefore, the spaces in front of the first and second housings communicate with the first space through this predetermined space. As a result, when air exhausted to the first space flows upward, air in front of the first housing, etc., is drawn into the first space through the predetermined space. This promotes an upward air current of the air exhausted to the first space, improving exhaust efficiency.

[0011] The exhaust section may have a communication port formed in the first side plate that connects the machine chamber and the electrical equipment chamber, and an exhaust port formed in the second back plate that exhausts air from the machine chamber to the first space through the communication port and the electrical equipment chamber.

[0012] In this configuration, air from the machinery compartment flows into the electrical compartment through the communication port and is then exhausted to the first space through the exhaust port in the second back panel. This allows the air from the electrical compartment to be exhausted through the exhaust port along with the air from the machinery compartment. As a result, there is no need to provide a separate exhaust space for exhausting the air from the electrical compartment, further reducing the required installation space.

[0013] The second bottom plate of the second housing is located higher than the first bottom plate of the first housing. The exhaust unit further has an air intake port formed in the second bottom plate for drawing air from a second space that faces a surface of the second bottom plate.

[0014] In the above configuration, a second space is formed between the second housing and, for example, the floor. Therefore, the spaces in front of the first and second housings communicate with the first space through the second space. Therefore, when air exhausted to the first space flows upward, the air in front of the first housing, etc., is drawn into the second space. A portion of the air drawn into the second space can flow into the first space. This promotes the upward airflow of the air exhausted to the first space, improving exhaust efficiency. Furthermore, the remainder of the air drawn into the second space flows into the electrical equipment compartment through the air intake and can then be exhausted to the first space through the exhaust port. This cools the electrical equipment in the electrical equipment compartment. That is, the air drawn into the second space is at room temperature, which is lower than the heat generation temperature of the electrical equipment. The electrical equipment is cooled by the air circulating through the electrical equipment compartment and being exhausted.

[0015] The communication opening may be located rearward of the center of the second housing in the front-rear direction.

[0016] In this configuration, the distance between the communication port and the exhaust port in the electrical equipment compartment is shorter than when the communication port is located forward of the center of the second housing in the front-to-rear direction. This reduces the area in the electrical equipment compartment through which air from the machinery compartment flows. This suppresses the temperature rise of the electrical components caused by air from the machinery compartment flowing through the electrical equipment compartment.

[0017] Another environment creating device of the present disclosure includes a first housing, a second housing, and an exhaust unit. The first housing has an item chamber for storing target items, and a machine chamber located below the item chamber and accommodating at least a portion of a refrigerator for cooling the target items in the item chamber. The second housing has an electrical equipment chamber for accommodating electrical components, and is provided in contact with a first side plate of the first housing. The exhaust unit exhausts air from the machine chamber. A second bottom plate of the second housing is located higher than the first bottom plate of the first housing. The exhaust unit exhausts air into a second space facing a surface of the second bottom plate.

[0018] In the above configuration, similar to the aforementioned environment-forming device, the refrigerator creates a desired environmental condition in the material compartment of the first housing, and the air in the machine compartment heated by, for example, a radiator of the refrigerator is exhausted by the exhaust unit. Here, the second bottom plate of the second housing is positioned higher than the first bottom plate of the first housing. Therefore, even if the first housing is installed with the first back plate of the first housing or the second side plate of the second housing close to the wall of the installation location, a second space is formed between the second housing and, for example, the floor. The air in the machine compartment is exhausted to the second space by the exhaust unit. The exhausted air flows through the second space, for example, toward the front. In this way, the second space is secured as an exhaust space even if the first housing is not installed away from the wall. Therefore, the required installation space can be reduced while still securing the exhaust space.

[0019] Yet another environment creating device of the present disclosure includes a first housing, a second housing, and an exhaust unit. The first housing has an item chamber for storing target items and a machine chamber located below the item chamber and accommodating at least a portion of a refrigerator for cooling the target items in the item chamber. The second housing has an electrical equipment chamber for accommodating electrical components and is provided in contact with a first side panel of the first housing. The exhaust unit exhausts air from the machine chamber. A second top plate of the second housing is located lower than the first top plate of the first housing. The exhaust unit exhausts air to a third space facing a surface of the second top plate.

[0020] In the above configuration, similar to the aforementioned environment-forming device, the refrigerator creates a desired environmental condition in the material compartment of the first housing, and the air in the machine compartment heated by, for example, a radiator of the refrigerator is exhausted by the exhaust unit. Here, the second bottom plate of the second housing is positioned higher than the first bottom plate of the first housing. Therefore, even if the first housing is installed in an installation location where the first top plate of the first housing is close to the ceiling, a third space is formed between the second housing and the ceiling. The air in the machine compartment is exhausted to the third space by the exhaust unit. The exhausted air flows through the third space, for example, toward the front. In this way, the third space is secured as an exhaust space even if the first housing is not installed far from the ceiling. Therefore, the required installation space can be reduced while still securing the exhaust space. [Effects of the Invention]

[0021] According to the environment forming device of the present disclosure, it is possible to reduce the required installation space while still ensuring an exhaust space. [Brief explanation of the drawings]

[Figure 8] 7A and 7B are views showing an environment forming device according to a modified example. DETAILED DESCRIPTION OF THE INVENTION

[0023] Exemplary embodiments will now be described in detail with reference to the accompanying drawings.

[0024] Fig. 1 is a front view showing the environment forming device 100. Fig. 2 is a plan view showing the environment forming device 100. Fig. 3 is a side view showing the environment forming device 100 as seen from the right side. Fig. 4 is a rear view showing the environment forming device 100. Fig. 5 is a cross-sectional view taken along line AA in Fig. 2.

[0025] The environment creating device 100 creates a desired environmental state in an item chamber 15 for storing a target item T. In this example, the environment creating device 100 is a refrigeration device that cools the target item T to a desired temperature. The environment creating device 100 includes a first housing 1, a second housing 2, a refrigerator 4, electrical components 5, and an exhaust unit 6. The target item T is, for example, food. In this example, as shown in FIG. 2, the environment creating device 100 is disposed with its right side along a first wall W1 of the room and its rear side along a second wall W2 of the room.

[0026] The first housing 1 has an article chamber 15 and a machine chamber 16 located below the article chamber 15. The article chamber 15 accommodates a target article T. The machine chamber 16 accommodates a part of the refrigerator 4 that cools the target article T in the article chamber 15.

[0027] Specifically, the first housing 1 is formed in a substantially rectangular box shape, more specifically, in a vertically elongated substantially rectangular box shape. That is, the first housing 1 has a first top panel 10, a first bottom panel 11, a first front panel 12, a first back panel 13, and two first side panels 14. When describing the two first side panels 14 separately, they are referred to as a first left side panel 14a and a first right side panel 14b.

[0028] As shown in Fig. 5, the first housing 1 has a partition plate 17 that divides the internal space into upper and lower sections. The space above the partition plate 17 in the first housing 1 is formed as an item compartment 15, and the space below the partition plate 17 in the first housing 1 is formed as a machine compartment 16. The first front panel 12 is formed by a door 12a that opens and closes the front side of the item compartment 15, and a fixed plate 12b that closes the front side of the machine compartment 16. As shown in Fig. 1, the fixed plate 12b has an air intake port 18 formed therein for taking in outside air into the machine compartment 16.

[0029] The portions of the first back panel 13 and the first side panel 14 that define the item compartment 15, the first top panel 10, the door 12a, and the partition panel 17 are formed as thermally insulated walls. The portions of the first back panel 13 and the first side panel 14 that define the machine compartment 16, and the first bottom panel 11 may be formed as thermally insulated walls or as walls that are not thermally insulated. In this example, the first housing 1 is provided on a horizontally extending base 3. In other words, the first housing 1 is placed on the floor F of the room via the base 3.

[0030] FIG. 6 is a piping diagram showing the refrigerator 4. As described above, the refrigerator 4 cools the target item T in the item chamber 15. The refrigerator 4 has a refrigerant circuit 41 in which a refrigerant circulates to perform a refrigeration cycle (more specifically, a vapor compression refrigeration cycle). The refrigerant circuit 41 is a closed circuit in which a compressor 42, a radiator 43, an expansion mechanism 44, and an evaporator 45 are connected in this order by piping. The refrigerator 4 also has a fan 46 for the radiator 43 and a fan 47 for the evaporator 45.

[0031] The compressor 42, the radiator 43, the expansion mechanism 44, and the fan 46 are housed in the machine room 16, and the evaporator 45 and the fan 47 are housed in the goods room 15. Although not shown, an air-conditioning room in which the evaporator 45 and the fan 47 are disposed is defined in the goods room 15. The fan 46 supplies air taken in through the air intake 18 to the radiator 43. In the radiator 43, the refrigerant exchanges heat with the air supplied by the fan 46, radiating heat and heating the air. The fan 47 circulates air between the goods room 15 and the evaporator 45. In the evaporator 45, the refrigerant exchanges heat with the air, absorbing heat, and cooling the air. The cooled air is supplied to the goods room 15, thereby cooling the target goods T to a desired temperature.

[0032] The second housing 2 has an electrical equipment compartment 25 formed therein and is provided in contact with the first side plate 14 of the first housing 1. The electrical equipment compartment 25 houses electrical components 5. In this example, the second housing 2 is provided in contact with the first right side plate 14b of the first housing 1. The electrical components 5 are electronic / electrical components for controlling the refrigerator 4, etc.

[0033] Specifically, the second housing 2 is formed in a substantially rectangular box shape, more specifically, in a vertically elongated substantially rectangular box shape. That is, the second housing 2 has a second top panel 20, a second bottom panel 21, a second front panel 22, a second back panel 23, and two second side panels 24. When describing the two second side panels 24 separately, they are referred to as the second left side panel 24a and the second right side panel 24b. The second housing 2 is attached to the first right side panel 14b of the first housing 1. That is, the second left side panel 24a of the second housing 2 and the first right side panel 14b of the first housing 1 are in surface contact. Note that the second top panel 20, the second bottom panel 21, the second front panel 22, the second back panel 23, and the two second side panels 24 may be formed as thermally insulated walls or as non-thermal walls.

[0034] 2 and other figures, the second back plate 23 of the second housing 2 is located forward of the first back plate 13 of the first housing 1. More specifically, the second front plate 22 of the second housing 2 is located rearward of the first front plate 12 of the first housing 1. In other words, the depth of the second housing 2 (i.e., the length in the front-to-rear direction) is shorter than the depth of the first housing 1.

[0035] 1 and other figures, the second bottom plate 21 of the second housing 2 is located higher than the first bottom plate 11 of the first housing 1. Furthermore, the second top plate 20 of the second housing 2 is located lower than the first top plate 10 of the first housing 1. In other words, the height of the second housing 2 (i.e., the length in the vertical direction) is shorter than the height of the first housing 1. The width of the second housing 2 (i.e., the length in the horizontal direction) is shorter than the width of the first housing 1.

[0036] The exhaust unit 6 exhausts air from the machine room 16. Specifically, the exhaust unit 6 exhausts air into a first space S1 that faces the surface of the second back panel 23. In other words, the second back panel 23 is positioned forward of the first back panel 13, thereby forming a first space S1 between the second back panel 23 and the second wall surface W2, and the exhaust unit 6 exhausts air into this first space S1. The first space S1 can be said to be a space that faces both the surface of the first side panel 14 (more specifically, the first right side panel 14b) and the surface of the second back panel 23. As shown in FIG. 3, the first space S1 extends in the vertical direction and communicates with a second space S2 and a third space S3, which will be described later.

[0037] The exhaust section 6 has an exhaust port 61 and a communication port 62 .

[0038] 5, the communication opening 62 is formed in the first side plate 14 of the first housing 1, and connects the machine compartment 16 and the electrical compartment 25. Specifically, the communication opening 62 is a hole that penetrates the first right side plate 14b of the first housing 1 and the second left side plate 24a of the second housing 2, which are adjacent to each other.

[0039] As shown in FIG. 4 , the exhaust port 61 is formed in the second back plate 23 of the second housing 2. The exhaust port 61 is an opening for exhausting air from the machine chamber 16 to the first space S1 through the communication port 62 and the electrical equipment chamber 25. Specifically, the air from the machine chamber 16 is sent by the fan 46 from the communication port 62 to the electrical equipment chamber 25 and then exhausted from the exhaust port 61 to the first space S1. In other words, the fan 46 of the refrigerator 4 also serves as the exhaust unit 6. In this example, the exhaust port 61 is formed in an upper part of the second back plate 23.

[0040] Fig. 7 is a cross-sectional view taken along line BB in Fig. 2. The communication opening 62 is located rearward of the center in the front-rear direction of the second housing 2. In other words, the communication opening 62 is located closer to the second back panel 23 in the front-rear direction of the electrical equipment compartment 25.

[0041] Furthermore, since the second bottom plate 21 is positioned higher than the first bottom plate 11, a second space S2 is formed that faces the surface of the second bottom plate 21. In other words, the second space S2 is formed between the second bottom plate 21 and the floor F. The second space S2 can be said to be a space that faces both the surface of the first side plate 14 (more specifically, the first right side plate 14b) and the surface of the second bottom plate 21. As shown in FIG. 3, the second space S2 extends in the front-rear direction, and connects the space on the front side of the first housing 1 and the second housing 2 with the first space S1.

[0042] Furthermore, since the second top panel 20 is positioned lower than the first top panel 10, a third space S3 is formed that faces the surface of the second top panel 20. In other words, the third space S3 can be said to be a space that faces both the surface of the first side panel 14 (more specifically, the first right side panel 14b) and the surface of the second top panel 20. The third space S3 extends in the front-to-rear direction, and connects the space on the front side of the first housing 1 and the second housing 2 with the first space S1.

[0043] A drain pipe 71 and a power line 72 are also connected to the environment creating device 100. The drain pipe 71 drains drainage generated in the machine room 16. Specifically, as shown in FIGS. 2 and 3, the drain pipe 71 is provided at the bottom of the first right side plate 14b of the first housing 1. More specifically, the drain pipe 71 is provided at a portion of the first right side plate 14b facing the first space S1. The drain pipe 71 communicates with the bottom of the machine room 16. In this manner, the drain pipe 71 is disposed in the first space S1. The power line 72 supplies power to the electrical components 5. Specifically, the power line 72 is connected to the second back plate 23 of the second housing 2, more specifically, to the upper part of the second back plate 23. In this manner, the power line 72 is also disposed in the first space S1.

[0044] In the environment creating device 100 configured as above, exhaust is performed as follows.

[0045] As shown by the arrows in FIG. 5, air heated by the radiator 43 in the machine room 16 (hereinafter also referred to as heated air) is sent out by the fan 46 from the communication port 62 to the electrical equipment room 25. The heated air sent out to the electrical equipment room 25 is exhausted to the first space S1 from the exhaust port 61, as shown by the solid arrows in FIG. 7. Here, because the communication port 62 is located closer to the second back panel 23 in the front-to-rear direction of the electrical equipment room 25, the area through which the heated air flows in the electrical equipment room 25 is kept small. Therefore, a temperature rise in the electrical equipment 5 due to the flow of heated air is suppressed. Furthermore, the air heated by the electrical equipment 5 in the electrical equipment room 25 is also exhausted from the exhaust port 61 together with the heated air from the machine room 16.

[0046] The heated air exhausted from the exhaust port 61 to the first space S1 flows upward in the first space S1 (see the solid arrows in FIG. 7). That is, because the heated air has a high temperature, an ascending air current of the heated air is formed in the first space S1. Furthermore, when the heated air flows upward in the first space S1, air on the front side of the first housing 1, etc. is taken into the first space S1 through the second space S2, as shown by the dashed arrows in FIG. 7. This promotes the ascending air current of the heated air in the first space S1.

[0047] The heated air exhausted to the first space S1 flows upward together with the air taken in from the second space S2 and is finally exhausted to the space on the ceiling side of the room. Also, even if there is almost no space on the ceiling side, i.e., even if there is almost no distance between the ceiling of the room and the first top plate 10, the heated air exhausted to the first space S1 flows to the front side of the first housing 1, etc., via the third space S3. In this way, the exhaust of the environment creating device 100 is performed.

[0048] According to the environment creating device 100 configured as above, it is possible to reduce the required installation space while ensuring the exhaust space.

[0049] Specifically, the environment creating device 100 includes a first housing 1 having an item chamber 15 and a machine chamber 16 formed above and below it; a second housing 2 having an electrical equipment chamber 25 formed therein and disposed adjacent to a first side panel 14 of the first housing 1; and an exhaust unit 6 that exhausts heated air from the machine chamber 16. The second back panel 23 of the second housing 2 is located forward of the first back panel 13 of the first housing 1. The exhaust unit 6 exhausts air into a first space S1 facing the surface of the second back panel 23. Therefore, even if the first housing 1 is installed with the first back panel 13 of the first housing 1 close to the second wall W2 of the installation location, the first space S1 is formed between the second housing 2 and the second wall W2. The heated air exhausted into the first space S1 flows upward through the first space S1. In this way, the first space S1 is secured as an exhaust space even if the first housing 1 is not installed far from the second wall W2. Therefore, the required installation space can be reduced while still ensuring the exhaust space.

[0050] Furthermore, the second bottom plate 21 of the second housing 2 is positioned higher than the first bottom plate 11 of the first housing 1. Therefore, a second space S2 is formed between the second housing 2 and the floor F. This allows the space in front of the first housing 1 and the second housing 2 to communicate with the first space S1 via the second space S2. Therefore, when the heated air exhausted to the first space S1 flows upward, the air in front of the first housing 1, etc. is taken into the first space S1 through the second space S2. This promotes an upward air current of the heated air exhausted to the first space S1, thereby improving exhaust efficiency.

[0051] Furthermore, the second top panel 20 of the second housing 2 is located lower than the first top panel 10 of the first housing 1. Therefore, even if there is almost no distance between the first top panel 10 of the first housing 1 and the ceiling of the installation location, a third space S3 is formed between the second housing 2 and the ceiling. This allows the space in front of the first housing 1 and the second housing 2 to communicate with the first space S1 via the third space S3. Therefore, heated air flowing upward through the first space S1 can flow into the space in front of the first housing 1, etc. This promotes an upward air current of the heated air exhausted into the first space S1, thereby improving exhaust efficiency.

[0052] The exhaust section 6 also has a communication port 62 formed in the first side panel 14 that connects the machine chamber 16 and the electrical equipment chamber 25, and an exhaust port 61 formed in the second back panel 23 that exhausts heated air from the machine chamber 16 to the first space S1 via the communication port 62 and the electrical equipment chamber 25. With this configuration, the heated air from the machine chamber 16 flows into the electrical equipment chamber 25 via the communication port 62 and is then exhausted to the first space S1 from the exhaust port 61 in the second back panel 23. Therefore, the air from the electrical equipment chamber 25 can be exhausted from the exhaust port 61 together with the heated air from the machine chamber. This eliminates the need to provide a separate exhaust space for exhausting the air from the electrical equipment chamber 25, thereby further reducing the required installation space.

[0053] Furthermore, the communication opening 62 is located rearward of the center in the front-to-rear direction of the second housing 2. With this configuration, the distance between the communication opening 62 and the exhaust port 61 in the electrical equipment chamber 25 is shorter than when the communication opening is located forward of the center in the front-to-rear direction of the second housing 2. This reduces the area in the electrical equipment chamber 25 through which the heated air from the machinery chamber 16 flows. This makes it possible to suppress a temperature rise in the electrical components 5 caused by the heated air from the machinery chamber 16 flowing through the electrical equipment chamber 25.

[0054] <<Variation>> In this modification, the configuration of the exhaust unit 6 is changed in the environment forming device 100 of the above embodiment. Fig. 8 is a view corresponding to Fig. 7 showing the environment forming device 100 according to the modification. In this modification, differences from the environment forming device 100 of the above embodiment will be described.

[0055] Specifically, the exhaust section 6 in this example further has an air intake port 63. The air intake port 63 is formed in the second bottom plate 21 of the second housing 2. The air intake port 63 draws air from the second space S2 that faces the surface of the second bottom plate 21. In other words, as the heated air in the machine chamber 16 flows through the electrical equipment chamber 25, air in the second space S2 can be drawn into the electrical equipment chamber 25 through the air intake port 63.

[0056] In this modification, as shown by the dashed arrows in FIG. 8 , a portion of the air taken into the second space S2 flows into the first space S1. Therefore, as in the previous embodiment, an upward air current of the heated air exhausted to the first space S1 is promoted. The remainder of the air taken into the second space S2 is drawn into the electrical equipment compartment 25 through the air intake port 63. The air drawn into the electrical equipment compartment 25 from the air intake port 63 is exhausted to the first space S1 through the air exhaust port 61 together with the heated air from the machinery compartment 16, as shown by the solid arrows in FIG. 8 . Here, the temperature of the air taken into the second space S2 is normal temperature, which is lower than the heat generation temperature of the electrical equipment 5 and the temperature of the heated air from the machinery compartment 16. Therefore, the air from the second space S2 flows through the electrical equipment compartment 25 and is exhausted, thereby cooling the electrical equipment 5.

[0057] In this modified example, the air intake 63 may be formed in any of the second top plate 20, the second front plate 22, and the second right side plate 24b instead of or in addition to the second bottom plate 21. The other configurations, actions, and effects are the same as those of the above embodiment.

[0058] Other Embodiments As described above, the above embodiment has been described as an example of the technology disclosed in this application. However, the technology of the present disclosure is not limited to this and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made as appropriate. Furthermore, the components described in the above embodiment can be combined to create new embodiments. Furthermore, the components described in the accompanying drawings and detailed description may include not only components essential for solving the problem, but also components that are not essential for solving the problem in order to exemplify the technology. Therefore, the fact that these non-essential components are described in the accompanying drawings or detailed description should not be interpreted as immediately determining that these non-essential components are essential.

[0059] For example, the second bottom plate 21 of the second housing 2 may coincide with the first bottom plate 11 of the first housing 1 in the vertical direction. In other words, the second space S2 does not have to be formed between the second housing 2 and the floor surface F. In that case, the second housing 2 may be placed on the base 3 shared with the first housing 1.

[0060] Furthermore, the second top plate 20 of the second housing 2 may coincide with the first top plate 10 of the first housing 1 in the vertical direction. In other words, the third space S3 facing the surface of the second top plate 20 does not have to be formed. Even with this configuration, if there is sufficient space between the first top plate 10 of the first housing 1 and the ceiling of the installation location, an exhaust space can be secured.

[0061] The exhaust port 61 may be formed in a portion of the first right side plate 14b of the first housing 1 that faces the first space S1, instead of in the second back plate 23 of the second housing 2. Naturally, the exhaust port 61 is provided in a position on the first right side plate 14b that allows communication between the machine chamber 16 and the first space S1. In other words, the exhaust unit 6 may be configured to exhaust heated air from the machine chamber 16 directly to the first space S1 without passing through the electrical equipment chamber 25. In this case, the communication port 62 is omitted.

[0062] The communication opening 62 is not limited to the above-mentioned position, and may be provided at any position as long as it allows communication between the machine room 16 and the electrical equipment room 25.

[0063] The exhaust unit 6 may exhaust air to the second space S2, which the surface of the second bottom plate 21 faces, instead of the first space S1. That is, the exhaust port 61 may be formed in the second bottom plate 21 instead of the second back plate 23. Here, when heated air from the machine chamber 16 is exhausted directly to the second space S2 without passing through the electrical equipment chamber 25, the exhaust port 61 is formed in a portion of the first right side plate 14b of the first housing 1 that faces the second space S2. In this case, the exhaust port 61 is also provided in a position on the first right side plate 14b that connects the machine chamber 16 and the second space S2. When exhausting air to the second space S2 in this way, air is exhausted from the second space S2 to the front side of the first housing 1, etc., even if the first space S1 and the third space S3 are not formed. Therefore, in this case, the required installation space can be reduced while ensuring an exhaust space.

[0064] The exhaust unit 6 may be configured to exhaust air to a third space S3 facing the surface of the second top plate 20, instead of the first space S1. In other words, the exhaust port 61 may be formed in the second top plate 20, instead of the second back plate 23. In this case, even if the first space S1 and the second space S2 are not formed, the air is exhausted from the third space S3 to the front side of the first housing 1, etc. Therefore, in this case too, it is possible to reduce the required installation space while ensuring the exhaust space.

[0065] The environment creating device 100 is not limited to the above-mentioned refrigeration device, but may be, for example, an environment testing device that adjusts the target object T in the object chamber 15 to a predetermined test temperature. [Explanation of symbols]
