Description

Technical Field

[0001] The present invention relates to an air conditioner, and particularly to a movable air conditioner in which a user side unit and a heat source side unit are integrally provided.

Background Art

[0002] Conventionally, there is known a movable air conditioner in which a user side unit and a heat source side unit are provided on a single movable base and which uses a refrigeration cycle.

[0003] For example, Patent Document 1 discloses an air conditioner including an indoor unit having an indoor heat exchanger and an indoor blower fan that sends air flowing through the indoor heat exchanger into a room, an outdoor heat exchanger connected to the indoor heat exchanger so that a refrigerant can circulate therethrough, an outdoor unit having an outdoor blower fan that sends air flowing through the outdoor heat exchanger, and a base having wheels that can move and on which the indoor unit and the outdoor unit are placed such that the suction ports of the indoor heat exchanger and the outdoor heat exchanger face each other.

[0004] This type of air conditioner is used for spot air conditioning, etc. in large spaces where it is difficult to install a normal air conditioner, such as factories, workplaces, warehouses, gymnasiums, etc., to efficiently cool or heat a working space by sending cold air or warm air near workers, etc.

[0005] Also, for example, Patent Document 2 discloses an air duct connection structure connected to this type of air conditioner, including a supply air duct that guides air cooled or heated by an air conditioner placed outdoors into a room, a return air duct that guides indoor air to the air conditioner, and an air duct connection plate formed with a supply air port to which the supply air duct is connected and a return air port to which the return air duct is connected, and the air duct connection plate is removably placed in an opening connected to the room.

[0006] This configuration allows for efficient circulation of air cooled or heated by an air conditioner placed outdoors into the room via supply and return air ducts. Therefore, even with a transport-type air conditioning system where the user unit and heat source unit are integrated outdoors, it can perform highly efficient circulating cooling or heating, just like a typical air conditioner where the indoor unit is installed indoors and the outdoor unit is installed outdoors. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2021-11984 [Patent Document 2] Japanese Patent Publication No. 2021-173444 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] However, the conventional mobile air conditioning systems described above had areas that needed improvement in order to further enhance the efficiency of cooling or heating.

[0009] Specifically, the air conditioner disclosed in Patent Document 1 has excellent performance in cooling operations in large spaces such as factories, for example, by powerfully blowing cool air from the indoor unit, which acts as the user-side unit, towards users. However, from the outdoor unit, which acts as the heat source side unit and is integrally provided with the indoor unit, warm air heated by the refrigerant in the outdoor heat exchanger, which acts as a condenser, is blown into the room.

[0010] Therefore, in order to perform efficient cooling operation, it is necessary to direct the warm air blown from the outdoor unit to a high place such as near the ceiling, away from the area to be cooled, or to the outside. However, in facilities with low ceilings, it is not easy to efficiently expel the warm air from the outdoor unit to the outside without heating the room, and it was sometimes necessary to install a separate fan or exhaust duct.

[0011] Furthermore, by adopting the air conduit connection structure disclosed in Patent Document 2, even in an air conditioning system in which the user-side unit and the heat source-side unit are integrally provided, efficient air conditioning operation can be performed, similar to a typical air conditioner in which the indoor unit is installed outdoors.

[0012] In other words, the air that has exchanged heat with the refrigerant in the outdoor heat exchanger of the outdoor unit is not brought into the room, and the air that has been cooled or heated in the indoor heat exchanger of the indoor unit is circulated to the air-conditioned space via the supply duct and return duct, enabling efficient air conditioning operation.

[0013] However, such air conduit connection structures require components such as supply air ducts, return air ducts, and air conduit connection plates, as well as the assembly of these components and the installation or removal of them from openings in the indoor unit and the space to be air-conditioned. Therefore, there was a need for a configuration with fewer parts that would make installation and other tasks easier.

[0014] The present invention has been made in view of the above circumstances, and its objective is to provide a portable air conditioning system that is easy to install and remove, easy to move and set up, and capable of high-efficiency air conditioning operation with low energy loss, like a typical air conditioner in which the outdoor unit is installed outdoors. [Means for solving the problem]

[0015] The air conditioning system of the present invention comprises a user-side unit having a user-side heat exchanger and a user-side blower fan installed in a user-side housing, and a heat source-side unit having a heat source-side heat exchanger and a heat source-side blower fan installed in a heat source-side housing, wherein the user-side unit and the heat source-side unit are mounted on a single frame and connected via refrigerant piping, wherein the user-side unit and the heat source-side unit are installed back-to-back with their respective outlets facing outward and their intake ports facing inward, and a partition plate larger than the user-side housing and the heat source-side housing is erected between the outlet of the user-side unit and the outlet of the heat source-side unit. [Effects of the Invention]

[0016] The air conditioning system of the present invention is an air conditioning system in which a user-side unit and a heat source-side unit are mounted on a single movable frame, and the user-side unit and the heat source-side unit are installed back-to-back with their respective outlets facing outward and their intake ports facing inward, and a partition plate larger than the user-side housing and the heat source-side housing is erected between the outlet of the user-side unit and the outlet of the heat source-side unit. With this configuration, the space on the outlet side of the user-side unit and the space on the outlet side of the heat source-side unit can be partitioned by the partition plate and the air flow can be separated. As a result, the mixing of air cooled or heated by the user-side heat exchanger and blown out from the outlet of the user-side unit and air heated or cooled by the heat source-side heat exchanger and blown out from the outlet of the heat source-side unit can be suppressed, and only the air blown out from the outlet of the user-side unit can be efficiently delivered to the air-conditioned space.

[0017] Specifically, for example, during cooling operation, the system prevents high-temperature air, including exhaust heat from the refrigerant, which is heated by the heat source-side heat exchanger and blown out from the heat source-side unit, from being returned to the air-conditioned space. Instead, it sends only the air that has been cooled by the refrigerant in the user-side heat exchanger and is now at a lower temperature, into the air-conditioned space.

[0018] Furthermore, for example, during heating operation, the air that has been cooled by the refrigerant in the heat source side heat exchanger is prevented from being returned to the air-conditioned space, and only the air that has been heated to a high temperature by the refrigerant in the user side heat exchanger is efficiently supplied to the air-conditioned space. In this way, the air conditioning system of the present invention enables efficient and energy-efficient circulating cooling or circulating heating.

[0019] Furthermore, according to the air conditioning device of the present invention, the partition plate may be removable to seal the entrance and exit of the space to be air-conditioned. This allows the entrance and exit of the space to be air-conditioned to be blocked by the partition plate, enabling the room to be air-conditioned to be cooled or heated with air blown out from the user-side unit, and the air blown out from the heat source-side unit to be discharged to the outside. In other words, even if it is a mobile air conditioning device in which the user-side unit and the heat source-side unit are mounted on a single movable frame, it can perform highly efficient cooling or heating operations like a typical packaged air conditioner or other air conditioning device with an outdoor unit installed outdoors.

[0020] Furthermore, since the partition plate can be easily removed to seal the entrance, users can remove the partition plate of the air conditioning unit from the entrance and easily move the air conditioning unit. In other words, the air conditioning unit of the present invention is easy to attach and detach to entrances, move and install, and can be moved to other locations for use as spot air conditioning, etc. In addition, the partition plate can be removed to close the door of the opening, and the door can also be locked. Therefore, the air conditioning unit of the present invention is also superior from the viewpoint of security.

[0021] Furthermore, according to the air conditioning device of the present invention, a sealing member that abuts against the frame of the entrance / exit may be provided on the edge of the partition plate. This allows the entrance / exit to be sealed easily and effectively, resulting in highly efficient air conditioning operation with minimal energy loss due to air leakage between the inside and outside of the building.

[0022] Further, according to the air conditioner of the present invention, the partition plate may be provided between the utilization side housing and the heat source side housing. With such a configuration, the partition plate can separate the space on the utilization side unit side and the space on the heat source side unit side. Therefore, the air in the air-conditioned space can be sent to the utilization side heat exchanger, and only the air cooled or heated by the utilization side heat exchanger can be sent to the air-conditioned space. Then, the air from the space separated from the air-conditioned space by the partition plate is sent to the heat source side heat exchanger, and the air heated or cooled by the heat source side heat exchanger is blown out into the space separated from the air-conditioned space. Thereby, highly efficient air conditioning can be performed, similar to a general air conditioner in which an indoor unit is provided indoors and an outdoor unit is provided outdoors.

[0023] Further, according to the air conditioner of the present invention, an opening is formed in the partition plate at a position corresponding to the air outlet of the heat source side unit, and the partition plate may be provided outside the heat source side housing. With such a configuration, the high-temperature air heated by the refrigerant by the heat source side heat exchanger or the low-temperature air absorbed by heat is blown out from the air outlet of the heat source side unit and sent out to the outside of the air-conditioned space partitioned by the partition plate. Therefore, highly efficient air conditioning operation can be performed.

[0024] Further, according to the air conditioner of the present invention, an opening is formed in the partition plate at a position corresponding to the air outlet of the utilization side unit, and the partition plate may be provided outside the utilization side housing. With such a configuration, the air cooled or heated by the utilization side heat exchanger is blown out from the air outlet of the utilization side unit and supplied to the air-conditioned space, and the air heated or cooled by the heat source side heat exchanger is blown out from the air outlet of the heat source side unit to the outside of the air-conditioned space partitioned by the partition plate. Therefore, highly efficient air conditioning operation can be performed.

[0026] Hereinafter, an air conditioning system 1 according to an embodiment of the present invention will be described in detail with reference to the drawings. Figure 1 is a side view showing a schematic configuration of an air conditioning system 1 according to an embodiment of the present invention. As shown in Figure 1, the air conditioning system 1 is a portable, powerful spot air conditioner in which the user-side unit 10 and the heat source-side unit 20 are integrally mounted on a frame 30. The air conditioning system 1 is a device that can cool or heat large spaces where it is difficult to install conventional package air conditioners or other air conditioning units, and may be used for air conditioning in places such as gymnasiums, factories, workshops, and warehouses.

[0027] The user-side unit 10 is a device that primarily cools or heats the air on the user side and supplies it. The user-side unit 10 has a configuration equivalent to the indoor unit of a typical packaged air conditioner.

[0028] Specifically, the user-side unit 10 has a housing 11 which is a roughly box-shaped enclosure made of a metal plate or the like, and a user-side heat exchanger 12 and a user-side blower fan 13, which are components that make up the refrigeration cycle, are provided inside the housing 11.

[0029] The heat source unit 20 is primarily a device that dissipates or absorbs heat from the refrigerant to the exhaust air. The heat source unit 20 has a configuration equivalent to the outdoor unit of a typical packaged air conditioner.

[0030] Specifically, the heat source side unit 20 has a housing 21 as the user side housing, which is a roughly box-shaped enclosure made of metal sheet material or the like, and a heat source side heat exchanger 22 and a heat source side blower fan 23, which are components that constitute the refrigeration cycle, are provided inside the housing 21.

[0031] The user-side heat exchanger 12 of the user-side unit 10 is connected to the heat source-side heat exchanger 22 of the heat source-side unit 20 via refrigerant piping 28. More specifically, the user-side heat exchanger 12 and the heat source-side heat exchanger 22 are connected via a compressor (not shown) that compresses low-pressure refrigerant to high pressure, an expansion valve (not shown) that expands high-pressure refrigerant to low pressure, refrigerant piping 28, and other refrigerant piping (not shown), forming a vapor compression type refrigeration cycle circuit. The refrigerant used in the refrigeration cycle is, for example, an HFC refrigerant.

[0032] The housing 11 of the user-side unit 10 has an air intake port 15 for drawing in air and an air outlet port 16 for blowing air into the air passage. Inside the air intake port 15, a user-side heat exchanger 12 is provided to perform heat exchange between the air drawn in from outside the housing 11 and the refrigerant. As a result, for example, during cooling operation, the user-side heat exchanger 12 acts as an evaporator, and the air drawn in from outside is cooled by the refrigerant that evaporates inside the user-side heat exchanger 12.

[0033] The outlet 16 is equipped with a user-side blower fan 13 that blows out the air inside the housing 11 that has exchanged heat with the user-side heat exchanger 12. The user-side blower fan 13 is, for example, a propeller fan and is rotationally driven by a motor (not shown).

[0034] In the air conditioning system 1 according to this embodiment, a particularly powerful user-side blower fan 13 is installed. Specifically, the user-side blower fan 13 has a powerful air-blowing capacity that blows air out from the outlet 16 at a wind speed of 8 m / s. As a result, a strong, directional wind can be delivered far from the outlet 16 in an indoor space 50 such as a gymnasium (see Figure 2), enabling efficient cooling or heating of a large indoor space 50.

[0035] The air outlet 16 is provided with a wind direction guide 14 for adjusting the direction of airflow supplied by the user-side blower fan 13. The wind direction guide 14 has an outer periphery that surrounds the outer circumference of the user-side blower fan 13, for example, in a substantially cylindrical shape. The interior of the wind direction guide 14, surrounded by its outer periphery, is an opening connected to the air outlet 16 through which the air flows, and a variable wind direction adjustment plate (not shown) is provided there to adjust the airflow. With this configuration, the air cooled or heated by the user-side heat exchanger 12 can be efficiently directed toward the air-conditioned object that requires it.

[0036] The housing 21 of the heat source unit 20 has an air intake port 25 for drawing in air and an air outlet port 26 for blowing out air. Inside the air intake port 25, there is a heat source side heat exchanger 22 that performs heat exchange between the air drawn in from the outside and the refrigerant. As a result, for example, during cooling operation, the refrigerant in the heat source side heat exchanger 22 is cooled by the air flowing in from the air intake port 25. In other words, the air drawn in from the air intake port 25 is heated by heat exchange with the refrigerant in the heat source side heat exchanger 22.

[0037] The outlet 26 is equipped with a heat source side blower fan 23 that blows out the air inside the housing 21 that has exchanged heat with the heat source side heat exchanger 22. The heat source side blower fan 23 is, for example, a propeller fan and is rotationally driven by a motor (not shown). For example, two heat source side blower fans 23 are provided, one above the other.

[0038] Furthermore, the air outlet 26 may be provided with an airflow guide 24 for adjusting the direction of air blown out by the heat source side blower fan 23. The airflow guide 24 has an outer frame portion that surrounds the outer circumference of the heat source side blower fan 23, for example, in a roughly rectangular shape, and is made of a metal plate material, a resin plate material, or the like. The airflow guide 24 is arranged in pairs, for example, one above the other, corresponding to the two heat source side blower fans 23 which are arranged vertically.

[0039] The support frame 30 is a base that integrally supports the user-side unit 10 and the heat source-side unit 20. The support frame 30 is formed from, for example, angle steel, channel steel, or other steel materials. A base 31 is formed at the lower part of the support frame 30, with its outer circumference forming a roughly rectangular frame shape when viewed from above. The heat source-side unit 20 is fixed to the upper part of the base 31.

[0040] The frame 30 has a user-side unit mounting base 32 for mounting the user-side unit 10. The user-side unit mounting base 32 is formed to protrude upward from the top of the base 31 so that the bottom of the user-side unit 10 can be supported at a higher position than the bottom of the heat source-side unit 20.

[0041] By providing a user-side unit mounting base 32 on top of the base 31, the user-side unit 10 is fixed at a high position. Also, the top surface of the user-side unit 10 and the top surface of the heat source-side unit 20 are at approximately the same height. By positioning the user-side unit 10 at a high position in this way, the position of the air outlet 16 of the user-side unit 10 is raised, allowing the cool or warm air for air conditioning to be blown widely and efficiently into the workspace.

[0042] The upper part of the user-side unit 10 and the upper part of the heat source-side unit 20 are connected and fixed by a connecting support member 33. This connecting support member 33 supports the upper part of the user-side unit 10 and the upper part of the heat source-side unit 20, suppressing deformation of the air conditioning system 1 due to vibrations during transport or use.

[0043] A drain pan (not shown) may be provided below the user-side unit 10 and the heat source-side unit 20. The drain pan is a component for receiving moisture that adheres to and drips from the user-side heat exchanger 12 of the user-side unit 10 or the heat source-side heat exchanger 22 of the heat source-side unit 20, and draining it into a drain pipe (not shown). By providing a drain pan, moisture dripping from the user-side heat exchanger 12 or the heat source-side heat exchanger 22 can be collected and drained effectively, and moisture can be prevented from splashing into the workspace.

[0044] Wheels 34 are provided near the lower corners of the base 31. The wheels 34 are, for example, casters with rubber wheels, and one end may be a fixed wheel that can move in a predetermined direction, while the other end may be a swivel wheel that can change direction. With the wheels 34 provided, the frame 30 is configured to be movable while integrally supporting the user-side unit 10 and the heat source-side unit 20.

[0045] The user-side unit 10 and the heat source-side unit 20 are mounted on the frame 30 such that their air intake ports 15 and 25 face each other. In other words, the user-side unit 10 and the heat source-side unit 20 are arranged so that the user-side heat exchanger 12 side and the heat source-side heat exchanger 22 side face each other.

[0046] In other words, the user-side unit 10 and the heat source-side unit 20 are arranged back-to-back so that their outlets 16 and 26 face in opposite directions, respectively, causing them to blow air in opposite directions.

[0047] As described above, by arranging the intake ports 15 and 25 opposite each other so that the air outlets 16 and 26 blow air in opposite directions, and by arranging the user-side unit 10 and the heat source-side unit 20 back to back, efficient air conditioning can be achieved for gymnasiums, large factories, logistics warehouses, and the like.

[0048] In other words, the cooling or heating air can be efficiently and powerfully blown from the outlet 16 of the user-side unit 10 into the room 50 to be air-conditioned. Then, the exhaust heat air for air conditioning can be discharged from the outlet 26 of the heat source-side unit 20, which faces the opposite side of the outlet 16 of the user-side unit 10, into a space away from the room 50 that requires air conditioning.

[0049] A partition plate 40 is provided between the outlet 16 of the user-side unit 10 and the outlet 26 of the heat source-side unit 20. More specifically, the partition plate 40 may be provided between the housing 11 of the user-side unit 10 and the housing 21 of the heat source-side unit 20.

[0050] The partition plate 40 is formed from a plate-shaped member made of synthetic resin or metal, and is erected between the housing 11, which is the user-side housing, and the housing 21, which is the heat source-side housing, to partition the space between the user-side unit 10 and the heat source-side unit 20.

[0051] The partition plate 40 has a roughly rectangular shape when viewed from the front (see Figure 3) and is placed on the base 31 of the frame 30. The area near the lower edge 41 of the partition plate 40 is fixed to the base 31 by a support member (not shown).

[0052] The partition plate 40 may be made from, for example, an aluminum plate. By making the partition plate 40 from a lightweight aluminum plate, the load that workers must support when transporting or installing the partition plate 40 is reduced, making the work easier.

[0053] Although not shown in the diagram, the partition plate 40 may have a bent portion at its end that is bent at approximately 90 degrees, or a folded portion that is bent back at approximately 180 degrees. By forming such a bent portion or folded portion, the partition plate 40 can obtain sufficient strength even if its thickness is reduced. Therefore, the partition plate 40 is made lighter, and the installation work of the partition plate 40 and the transportation and installation work of the air conditioning unit 1 become easier. Furthermore, the partition plate 40 may be provided with other metal support members, such as frames or pipes (not shown), in order to ensure the strength of the roughly rectangular plate-shaped main body.

[0054] The partition plate 40 may have through holes 44 through which connecting support members 33, which connect and fix the upper part of the user-side unit 10 and the upper part of the heat source-side unit 20, are inserted. The partition plate 40 may be fixed to the connecting support members 33 by support members (not shown) at the through holes 44.

[0055] The partition plate 40 may have a piping hole 46 through which a refrigerant pipe 28 connecting the user-side unit 10 and the heat source-side unit 20 is inserted. Alternatively, a notch (not shown) may be formed near the lower edge 41 of the partition plate 40, and the refrigerant pipe 28 may be inserted into this notch. By forming a notch on the lower edge 41 side of the partition plate 40 in this way, the partition plate 40 can be attached to the air conditioning system 1 in which the refrigerant pipe 28 is formed.

[0056] Figure 2 is a side view showing the installed state of the air conditioning unit 1. As shown in Figure 2, the air conditioning unit 1 may be installed, for example, at an entrance 53 of a gymnasium or the like. The air conditioning unit 1 can be easily moved on the floor surface 56 of the room 50 by operation by the user, and is installed at the entrance 53 so that the heat source side unit 20 faces the outside 51 side. In other words, the air conditioning unit 1 is easily attached to and detached from the entrance 53, with the user side unit 10 installed in the room 50 and the heat source side unit 20 installed outside 51.

[0057] Figure 3 is a front view showing the installed state of the air conditioning unit 1. As shown in Figure 3, the partition plate 40 is formed to be larger than the user-side unit 10 and the heat source-side unit 20 (see Figure 2) when viewed from the front.

[0058] For details, please refer to Figures 2 and 3. The partition plate 40 is formed such that its lower edge 41 is close to the floor surface 56, and its upper edge 42 is higher than the housing 11 of the user-side unit 10 and higher than the housing 21 of the heat source-side unit 20.

[0059] Figure 4 is a plan view showing the installed state of the air conditioning unit 1. Referring to Figures 3 and 4, the lateral dimensions of the partition plate 40 are larger than the housing 11 of the user-side unit 10 and larger than the housing 21 of the heat source-side unit 20. The left and right sides 43 of the partition plate 40 protrude outward to the left and right from the sides of the housings 11 and 21.

[0060] Referring to Figures 2 to 4, the partition plate 40 is formed to be larger than the entrance 53 of the room 50 that is to be air-conditioned, when viewed from the front. That is, the partition plate 40 is higher than the entrance 53 formed in the wall 52 of the gymnasium, etc., and wider than the entrance 53. As a result, the entrance 53 is blocked by the partition plate 40.

[0061] Specifically, as shown in Figures 2 and 3, the upper edge 42 of the partition plate 40 is positioned higher than the entrance / exit 53. The exterior side 51 of the partition plate 40 near the upper edge 42 abuts directly or via the sealing member 48 against the upper frame 54 or wall 52 of the entrance / exit 53.

[0062] Furthermore, as shown in Figures 3 and 4, the horizontal dimensions of the partition plate 40, i.e., the lengths of the lower edge 41 and the upper edge 42, are longer than the horizontal dimensions of the entrance / exit 53. The exterior side 51 of the partition plate 40 near the side edge 43 abuts directly or via the sealing member 48 against the left and right frame portions 54 or walls 52 of the entrance / exit 53.

[0063] The doors 55 of the entrance / exit 53 may be a double-opening type with a pair of doors on the left and right, or, although not shown in the illustration, they may be a single-opening type with only one door. Also, if the doors 55 are of the double-opening type, the entrance / exit 53 in which the air conditioning unit 1 is installed may be formed with both doors 55 open, or, although not shown in the illustration, it may be formed with only one door 55 open. When the air conditioning unit 1 is installed in an entrance / exit 53 with only one door 55 open, the exterior side 51 side of the partition plate 40 near the side edge 43 on the door 55 side will be in contact with the closed door 55 directly or via the sealing member 48.

[0064] Referring to Figures 2 to 4, by blocking the entrance 53 with the partition plate 40 in this way, air leakage from the indoor 50 to the outdoor 51 and the entry of outside air from the outdoor 51 to the indoor 50 are suppressed, enabling highly efficient air conditioning with minimal heat loss.

[0065] More specifically, the user-side unit 10 can draw in air from the room 50, cool or heat it with a refrigerant, and blow it back into the room 50. The heat source-side unit 20 can draw in air from the outside 51, release or absorb heat from the refrigerant to the air in the outside 51, and then discharge that air to the outside 51.

[0066] In other words, by blocking the entrance 53 of the space to be air-conditioned with the partition plate 40, the air conditioning unit 1 can cool or heat the room 50 to be air-conditioned with the air blown out from the user-side unit 10, and discharge the air blown out from the heat source-side unit 20 to the outside 51.

[0067] Thus, even with a mobile air conditioning system 1 in which the user-side unit 10 and the heat source-side unit 20 are mounted on a single movable frame, it is possible to perform highly efficient cooling or heating operations, just like with a typical packaged air conditioner or other air conditioning system in which an indoor unit is installed in the room 50 and an outdoor unit is installed outside 51.

[0068] As shown in Figure 3, a notch 45 is formed in the lower edge 41 of the partition plate 40 into which the base 31 of the frame 30 is fitted. This makes it easier to place the partition plate 40 on the frame 30, and also allows the partition plate 40 to partition the indoor area 50 and the outdoor area 51 below the base 31.

[0069] Furthermore, a sealing plate (not shown) that closes the notch 45 may be attached to the partition plate 40. This eliminates air leakage from the notch 45, enabling even more efficient air conditioning operation.

[0070] Furthermore, referring to Figures 2 and 4, sealing members 48 may be provided near the edges of the partition plate 40, i.e., the upper edge 42 and the side edge 43, to abut against the frame portion 54 and close the entrance 53. The sealing members 48 may be formed from, for example, a sheet material made of synthetic resin material or synthetic fiber. The sealing members 48 may also be bonded to the partition plate 40 using an adhesive sheet material (not shown).

[0071] By providing sealing members 48 near the upper edge 42 and the side edge 43 of the partition plate 40 in this manner, the entrance 53 can be easily and effectively sealed. Since the space between the partition plate 40 and the frame portion 54 is almost completely sealed, air leakage can be further reduced, and air conditioning performance can be further improved.

[0072] As explained above, the air conditioning system 1 can separate the indoor area 50 on the user-side unit 10 side from the outdoor area 51 on the heat source-side unit 20 side by the partition plate 40. In other words, the indoor area 50 and the outdoor area 51 can be separated by making the partition plate 40 larger than the entrance / exit 53. This allows the air from the indoor area 50, which is the space to be air-conditioned, to be sent to the user-side heat exchanger 12, and only the air that has been cooled or heated by the user-side heat exchanger 12 to be sent back to the indoor area 50.

[0073] Then, only air from the outside 51, separated from the room 50 by the partition plate 40, is sent to the heat source side heat exchanger 22, and the air heated or cooled by the heat source side heat exchanger 22 is blown out to the outside 51, separated from the room 50.

[0074] As a result, the air conditioning system 1 can perform highly efficient air conditioning, similar to a typical packaged air conditioner or other air conditioning unit in which an indoor unit is provided in the indoor area 50 and an outdoor unit is provided in the outdoor area 51.

[0075] Furthermore, the partition plate 40 can be easily removed to seal the entrance / exit 53. Therefore, users can easily remove the partition plate 40 of the air conditioning unit 1 from the entrance / exit 53 and move the air conditioning unit 1.

[0076] In other words, the air conditioning unit 1 is easy to attach to and detach from the entrance / exit 53, move, and install, and can be moved to other locations for use as spot air conditioning, etc. Furthermore, users can move the air conditioning unit 1 to remove the partition plate 40 from the entrance / exit 53, close the door 55 of the entrance / exit 53, and even lock the door 55. Therefore, the air conditioning unit 1 according to this embodiment is also excellent from the viewpoint of security.

[0077] Furthermore, the air conditioning unit 1 is a movable device and may be used without the partition plate 40 blocking the entrance / exit 53. Specifically, the air conditioning unit 1 may be installed and used inside factories, workshops, warehouses, gymnasiums, etc. Even when used in this manner, the air conditioning unit 1 is separated by the partition plate 40 from the space to be air-conditioned on the user side unit 10 and the space on the heat source side unit 20, thereby suppressing the mixing of cold and hot air, and enabling highly efficient spot air conditioning operation.

[0078] Furthermore, if the air conditioning unit 1 is used inside a factory or workshop, the air conditioning unit 1 may be installed in combination with other partitions installed in the factory or workshop, etc., on the partition plate 40.

[0079] Next, with reference to Figures 5 to 7, the air conditioning system 101 will be described in detail as an example of a modified embodiment. Components that have the same or similar functions and effects as those in the previously described embodiments are denoted by the same reference numerals, and their descriptions are omitted.

[0080] Figure 5 is a side view showing a schematic configuration of an air conditioning system 101 according to another embodiment of the present invention. Referring to Figure 5, the air conditioning unit 101 has a partition plate 140 provided on the outer surface of the housing 21 of the heat source unit 20, that is, on the side facing the air outlet 26.

[0081] The partition plate 140 is composed of a plate-like member with a roughly rectangular shape, similar to the partition plate 40 (see Figure 1) described earlier, and is larger than the user-side unit 10 and the heat source-side unit 20, and is provided on the side of the housing 21 facing the air outlet 26.

[0082] Figure 6 is a rear view showing the schematic configuration of the air conditioning unit 101. Referring to Figure 6, the partition plate 140 has an opening 47 at a position corresponding to the outlet 26 of the heat source side unit 20. As a result, the air blown out from the outlet 26 passes through the opening 47 of the partition plate 140 and flows outwards.

[0083] Specifically, referring to Figures 5 and 6, the partition plate 140 separates the space on the outlet 16 side of the user-side unit 10 from the space on the outlet 26 side of the heat source-side unit 20. This suppresses the mixing of air that has been cooled or heated by the user-side heat exchanger 12 and blown out from the outlet 16 of the user-side unit 10, and air that has been heated or cooled by the heat source-side heat exchanger 22 and blown out from the outlet 26 of the heat source-side unit 20. As a result, the air blown out from the outlet 16 of the user-side unit 10 can be efficiently delivered to the air-conditioned space.

[0084] Figure 7 is a side view showing the installed state of the air conditioning unit 101, and Figure 8 is a top view showing the installed state of the air conditioning unit 101. Referring to Figures 7 and 8, the air conditioning unit 101 may be installed, for example, at an entrance 53 of a gymnasium or the like. Specifically, the air conditioning unit 101 is installed at the entrance 53 so that it moves on the floor surface 56 of the room 50 when pushed by a user, and the outlet 26 of the heat source unit 20 faces the outside 51.

[0085] Here, the partition plate 140 is formed to be larger than the entrance 53, and the entrance 53 is blocked by the partition plate 140. In other words, the interior 50 and the exterior 51 are separated by the partition plate 140.

[0086] Both the user-side unit 10 and the heat source-side unit 20 will be installed in the room 50, but the outlet 26 of the heat source-side unit 20 is provided to discharge air towards the outside 51.

[0087] With the air conditioning unit 101 arranged in this manner, the high-temperature air heated by the refrigerant in the heat source side heat exchanger 22, or the low-temperature air that has absorbed heat, is blown out from the outlet 26 of the heat source side unit 20 to the outside 51 separated by the partition plate 140, without being returned to the room 50.

[0088] This suppresses the mixing of air that is cooled or heated by the user-side heat exchanger 12 and blown out from the outlet 16 of the user-side unit 10, and air that is heated or cooled by the heat source-side heat exchanger 22 and blown out from the outlet 26 of the heat source-side unit 20. As a result, only the air blown out from the outlet 16 of the user-side unit 10 can be efficiently delivered to the room 50, which is the space to be air-conditioned.

[0089] Specifically, for example, during cooling operation, the return of high-temperature air, including exhaust heat from the refrigerant, which is heated by the heat source side heat exchanger 22 and blown out from the heat source side unit 20, to the room 50 of the space to be air-conditioned is suppressed. Then, only the air that has been cooled by the refrigerant in the user side heat exchanger 12 and has become low in temperature can be sent to the room 50.

[0090] Furthermore, for example, during heating operation, the system prevents the air that has been cooled by the refrigerant in the heat source side heat exchanger 22 from being returned to the room 50 of the air-conditioned space, and efficiently supplies only the air that has been heated by the refrigerant in the user side heat exchanger 12 to the room 50. Thus, according to the air conditioning system 101 of this embodiment, efficient and energy-efficient circulating cooling or circulating heating can be performed.

[0091] Next, with reference to Figures 9 and 10, an air conditioning system 201 will be described in detail as a further modified example of the embodiment. Components that have the same or similar functions and effects as those in the previously described embodiment are denoted by the same reference numerals, and their descriptions are omitted.

[0092] Figure 9 is a side view showing a schematic configuration of an air conditioning system 201 according to another embodiment of the present invention. Referring to Figure 9, the air conditioning unit 201 has a partition plate 240 provided on the outer surface of the housing 11 of the user-side unit 10, that is, on the side facing the air outlet 16.

[0093] The partition plate 240 is composed of a plate-like member with a substantially rectangular shape, similar to the partition plate 40 (see Figure 1) already described, and is larger than the user-side unit 10 and the heat source-side unit 20, and is provided on the side of the housing 11 facing the air outlet 16. Although not shown in the illustration, the partition plate 240 may be provided at a position away from the outer surface of the housing 11 and fixed near the front side of the support frame 30.

[0094] The partition plate 240 has an opening 247 formed at a position corresponding to the air outlet 16 of the user-side unit 10. The air direction guide 14 of the user-side unit 10 is inserted into the opening 247. As a result, the air blown out from the air outlet 16 flows through the opening 247 of the partition plate 240 towards the space to be air-conditioned.

[0095] In other words, the air conditioning unit 201 is partitioned by a partition plate 240 between the space on the outlet 16 side of the user-side unit 10 and the space on the outlet 26 side of the heat source-side unit 20. This suppresses the mixing of air that has been cooled or heated by the user-side heat exchanger 12 and blown out from the outlet 16 of the user-side unit 10, and air that has been heated or cooled by the heat source-side heat exchanger 22 and blown out from the outlet 26 of the heat source-side unit 20. As a result, only the air blown out from the outlet 16 of the user-side unit 10 can be efficiently delivered to the space to be air-conditioned.

[0096] Figure 10 is a side view showing the installed state of the air conditioning unit 201. Referring to Figures 9 and 10, the air conditioning unit 201 may be installed, for example, at an entrance 53 of a gymnasium or the like. Specifically, the air conditioning unit 201 is installed at the entrance 53 so that it moves on the floor surface 56 of the room 50 when pushed by a user, and the outlet 26 of the heat source unit 20 faces the outside 51.

[0097] Here, the partition plate 240 is formed to be larger than the entrance / exit 53. As a result, the entrance / exit 53 is blocked by the partition plate 240. In other words, the interior 50 and the exterior 51 are separated by the partition plate 240.

[0098] Both the user-side unit 10 and the heat source-side unit 20 will be installed outdoors 51, but the air outlet 16 of the user-side unit 10 is configured to blow air towards the room 50.

[0099] With the air conditioning unit 201 installed in this manner, the high-temperature air heated by the refrigerant in the heat source side heat exchanger 22, or the low-temperature air that has absorbed heat, is not returned to the room 50 from the outlet 26 of the heat source side unit 20, but is instead blown out to the outside 51 separated by the partition plate 240.

[0100] This suppresses the mixing of air that is cooled or heated by the user-side heat exchanger 12 and blown out from the outlet 16 of the user-side unit 10, and air that is heated or cooled by the heat source-side heat exchanger 22 and blown out from the outlet 26 of the heat source-side unit 20. As a result, only the air blown out from the outlet 16 of the user-side unit 10 can be efficiently delivered to the room 50, which is the space to be air-conditioned.

[0101] Specifically, for example, during cooling operation, the high-temperature air, including exhaust heat from the refrigerant, which is heated by the heat source side heat exchanger 22 and blown out from the heat source side unit 20, is not returned to the room 50 of the space to be air-conditioned. Instead, only the air that has been cooled by the refrigerant in the user side heat exchanger 12 and is now at a low temperature is sent to the room 50.

[0102] Furthermore, for example, during heating operation, the system prevents the air that has been cooled by the refrigerant in the heat source side heat exchanger 22 from being returned to the room 50 of the air-conditioned space, and efficiently supplies only the air that has been heated by the refrigerant in the user side heat exchanger 12 to the room 50. Thus, according to the air conditioning system 201 of this embodiment, efficient cooling or heating with low energy consumption can be performed.

[0103] In the above description, examples have been given in which substantially the entire area of ​​the inlet / outlet 53 is blocked by partition plates 40, 140, and 240 as air conditioning devices 1, 101, and 201 according to this embodiment. However, the sealing configuration of the inlet / outlet 53 is not limited to this. For example, the height dimensions of the partition plates 40, 140, and 240 may be smaller than the height dimension of the inlet / outlet 53. In that case, the lower area of ​​the inlet / outlet 53 is blocked by the partition plates 40, 140, and 240, and other sealing members (not shown) may be provided in the upper area of ​​the inlet / outlet 53.

[0104] For example, as another sealing member to close the upper area of ​​the entrance 53, a curtain-like sealing member suspended from the upper wall 52 of the entrance 53 may be provided. Alternatively, as another sealing member to close the upper area of ​​the entrance 53, a curtain material made of polyvinyl chloride resin film or the like may be used. With such a configuration, the air conditioning units 1, 101, and 201 can be easily moved and installed, and as described above, the performance of the air conditioning operation can be improved.

[0105] It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. [Explanation of Symbols]
