[0005] , , , ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Furthermore, if two ducts—an exhaust duct and an intake duct—are installed to solve the aforementioned problems, the installation space for the ducts becomes bulky. Additionally, the large space required for duct housing leads to higher transportation costs.

[0006] Therefore, the present invention aims to provide an integrated air conditioning system that can improve cooling efficiency and can be compactly constructed. [Means for solving the problem]

[0007] (1) The integrated air conditioning system of the present invention, provided to solve the above-mentioned problems, comprises a case having an indoor air intake, an indoor air outlet, an outdoor air intake, and an outdoor exhaust port, the case having a compressor, evaporator, and condenser that constitute a refrigeration cycle inside, the outdoor air intake is connected to an intake duct that communicates with the external area of ​​the case, the outdoor exhaust port is connected to an exhaust duct that communicates with the external area, the intake duct allows outside air supplied to the case to flow in from the external area, and the exhaust duct is, The warm air exhausted from the outdoor exhaust port is exhausted towards the outside area, a first airflow path is formed between the indoor intake port and the indoor outlet port, a second airflow path is formed between the outdoor intake port and the outdoor exhaust port, the evaporator and first fan are arranged in the first airflow path, the condenser and second fan are arranged in the second airflow path, and the intake duct and the exhaust duct are integrally formed to form an intake and exhaust duct.

[0008] The integrated air conditioning system described above has an intake duct and an exhaust duct, and separates the first air supply path for indoor intake and exhaust, and the second air supply path for outdoor intake and exhaust. Therefore, indoor intake and exhaust can be performed independently of outdoor intake and exhaust. In addition, the integrated air conditioning system described above can improve cooling efficiency because it can suppress the mixing of cooled air with the exhaust and discharge from the exhaust duct.

[0009] Furthermore, since the intake and exhaust ducts of the aforementioned integrated air conditioning unit are integrally formed, these ducts can be made smaller. As a result, the packaging size of the aforementioned integrated air conditioning unit can be reduced, which in turn can reduce transportation costs. In addition, because the intake and exhaust ducts of the aforementioned integrated air conditioning unit are integrated, installation to the main unit or to window frames, etc., can be easily performed.

[0010] Furthermore, the integrated air conditioning unit described above has an intake duct and an exhaust duct, and the intake duct is connected to the outside. Therefore, in the integrated air conditioning unit described above, negative pressure inside the case is suppressed, and intake and exhaust are reliably separated. Consequently, the integrated air conditioning unit described above can improve cooling efficiency.

[0011] (2) The integrated air conditioning system of the present invention described above has an intake and exhaust duct which each has a cylindrical inner duct and an outer duct, and one of the intake duct and the exhaust duct is made up of the inner duct, and the other of the intake duct and the exhaust duct is made up of the outer duct, and the inner duct and the outer duct form a double structure.

[0012] The integrated air conditioning system described above, by adopting this configuration, allows the intake duct and exhaust duct to be integrated into a single intake and exhaust duct. This reduces the space required for installing the intake and exhaust ducts. Therefore, the integrated air conditioning system can be made more versatile in terms of installation. Furthermore, since the intake and exhaust ducts are integrated into a single intake and exhaust duct, the packaging size of the duct can be reduced. This reduces the transportation costs of the integrated air conditioning system. In addition, the integrated air conditioning system can also improve the ease of installation of the intake and exhaust ducts.

[0013] (3) In the integrated air conditioning device of the present invention described above, the exhaust duct is configured as the inner duct and the intake duct is configured as the outer duct.

[0014] The integrated air conditioning system described above, with this configuration, can suppress the release of heat from the warm air passing through the inner duct into the room. In other words, the outside air (low-temperature gas) passing through the outer duct traps the heat of the warm air passing through the inner duct. Therefore, the integrated air conditioning system described above can improve the cooling efficiency of the room.

[0015] (4) The integrated air conditioning device of the present invention described above may have an insulating layer between the inner duct and the outer duct.

[0016] The integrated air conditioning system described above, with this configuration, can suppress heat exchange between the warm air passing through the inner duct (exhaust duct) and the outside air passing through the outer duct (intake duct). In other words, the temperature rise of the outside air passing through the outer duct is suppressed, and the outside air is supplied to the condenser while maintaining its temperature. Therefore, the integrated air conditioning system described above can suppress a decrease in the efficiency of heat exchange in the refrigeration cycle.

[0017] (5) The integrated air conditioning device of the present invention described above has an intake and exhaust duct having a mounting portion at the opening end on the side of the external region for fixing the opening end, and the mounting portion has an inner duct exhaust port for air discharged from the inner duct and an outer duct intake port for air drawn in from the outer duct, and it is preferable that the inner duct exhaust port and the outer duct intake port are arranged to be separated.

[0018] The integrated air conditioning system described above, with this configuration, can suppress the intake of warm air immediately after exhaust from the outer duct (intake duct). Furthermore, since the integrated air conditioning system described above has a mounting portion at the opening end on the external side, the intake and exhaust ducts can be easily attached to, for example, a window frame using this mounting portion.

[0019] (6) The integrated air conditioner of the present invention described above has an inner cylinder connected to the inner duct and an outer cylinder connected to the outer duct, and the inner cylinder preferably has an extension portion formed such that the tip extends from the opening end of the outer cylinder.

[0020] Since the integrated air conditioner described above has an extension portion, the opening end of the inner cylinder (inner duct) and the opening end of the outer cylinder (outer duct) can be separated. Therefore, the integrated air conditioner described above can suppress the mixing of the warm air discharged from the inner cylinder and the outside air sucked from the outer cylinder. As a result, the integrated air conditioner described above can further improve the cooling efficiency in the room.

[0021] (7) In the integrated air conditioner of the present invention described above, the extension portion preferably has an outer flange portion protruding outward in the radial direction of the inner cylinder.

[0022] With such a configuration, the integrated air conditioner described above can suppress the mixing of the warm air discharged from the inner duct (exhaust duct) and the outside air sucked from the outer duct (intake duct). That is, the outer flange portion serves as a partition wall separating the exhaust port of the inner duct and the intake port of the outer duct. As a result, the integrated air conditioner described above can improve the cooling efficiency in the room.

[0023] (8) In the integrated air conditioner of the present invention described above, an extension pipe extending in the axial direction of the inner cylinder is preferably provided on the extension portion.

[0024] With such a configuration, the integrated air conditioner described above can further separate the exhaust port of the inner duct and the intake port of the outer duct. As a result, the integrated air conditioner described above can further improve the cooling efficiency in the room.

[0025] (9) In the integrated air conditioner of the present invention described above, it is preferable that the space between the outdoor exhaust port and the second fan is connected by a pipe.

[0026] With such a configuration, the above-described integrated air conditioner can surely guide the warm air discharged from the second fan to the outdoor exhaust port. Therefore, the above-described integrated air conditioner can prevent the warm air discharged from the second fan from mixing with the outside air on the intake side. As a result, the above-described integrated air conditioner can further improve the cooling efficiency in the room.

Effects of the Invention

[0027] According to the present invention, it is possible to provide an integrated air conditioner that can improve cooling efficiency and can be formed compactly.

Modes for Carrying Out the Invention

[0029] An embodiment of the integrated air conditioner 1 of the present invention will be described in detail below with reference to FIGS. 1 to 6. Note that it should be noted that the dimensions in each figure may differ from the actual ratio for convenience of explanation.

[0030] As shown in Figures 1 to 3, the integrated air conditioning system 1 of the present invention has the main unit housed in a case 2. In addition, an intake and exhaust duct 50, which has an intake duct 51 and an exhaust duct 52 integrally formed thereon, is connected to the rear side of the case 2.

[0031] As shown in Figure 1, Case 2 is formed as a vertically elongated box and is equipped with an indoor air intake 10, an indoor air outlet 12, an outdoor air intake 14, and an outdoor exhaust 16. Case 2 also houses the compressor 20, evaporator 22, and condenser 24 that constitute the refrigeration cycle. In addition to the above, Case 2 also houses a first fan 30 (also referred to as the indoor fan 30) and a second fan 35 (also referred to as the outdoor fan 35), etc.

[0032] As shown in Figures 1 and 3, the indoor intake port 10 is located on the rear side of the case 2, connecting the inside of the case 2 to the room. The indoor intake port 10 is designed to draw in air from the room where the integrated air conditioning unit 1 is installed into the case 2. The indoor intake port 10 is also equipped with a filter (not shown), which is designed to prevent dust and foreign matter from entering the inside of the case 2.

[0033] As shown in Figures 1 and 2, the indoor air outlet 12 is located on the front side (front side) of the case 2, connecting the inside of the case 2 to the room. The indoor air outlet 12 is designed to blow out the indoor air drawn in from the indoor intake 10 into the room via the evaporator 22, which will be described later.

[0034] As shown in Figure 1, a first air supply path 40 is formed between the indoor intake port 10 and the indoor outlet port 12. An evaporator 22 and a first fan 30 are arranged in the first air supply path 40. The first air supply path 40 is separated by a partition wall with an insulated outer perimeter, and forms a passage for circulating air drawn in from the indoor intake port 10 toward the indoor outlet port 12.

[0035] The first fan 30 is, for example, a sirocco fan and is connected to a motor 31. The first fan 30 is rotationally driven by the driving force of the motor 31. When the first fan 30 is rotationally driven, an airflow is generated from the indoor intake port 10 toward the indoor outlet port 12. As a result, indoor air is drawn in from the indoor intake port 10 and exhausted from the indoor outlet port 12.

[0036] The outdoor air intake port 14 is formed in an annular shape and is located on the rear side (back side) of the case 2. The outdoor air intake port 14, together with the outdoor exhaust port 16, forms a connecting adapter (not shown) for connecting the intake and exhaust duct 50, which will be described later. In this embodiment, the outdoor air intake port 14 is located near the middle of the case 2 and is formed to surround the outdoor exhaust port 16, which will be described later. One end of the intake duct 51, which will be described later, is connected to the outdoor air intake port 14, and it communicates with the external area 5 via the intake duct 51. The external area 5 is the area outside (outside) the window 3 (see Figure 2). The outdoor air intake port 14 is designed to draw in (inhale) outside air from the external area 5 into the case 2. The outdoor air intake port 14 is also provided with a filter (not shown), which is designed to prevent dust and foreign matter from entering the case 2.

[0037] The outdoor exhaust port 16 is formed in a cylindrical shape and is located inside the outdoor intake port 14. In other words, in this embodiment, the outdoor intake port 14 and the outdoor exhaust port 16 are formed in a double cylindrical shape. The outdoor exhaust port 16 communicates with the external area 5 via an exhaust duct 52, which will be described later. The outdoor exhaust port 16 is designed to exhaust outside air flowing in from the outdoor intake port 14 to the external area 5 via a condenser 24, which will be described later. As will be described in detail later, warm air that has undergone heat exchange in the condenser 24 is exhausted from the outdoor exhaust port 16.

[0038] A second airflow path 42 is formed between the outdoor air intake 14 and the outdoor exhaust 16. A condenser 24 and a second fan 35 are arranged in the second airflow path 42. The second airflow path 42 is separated by a partition wall with an insulated outer perimeter, and forms a passage for circulating outside air drawn in from the outdoor air intake 14 toward the outdoor exhaust 16.

[0039] The second fan 35 is formed, for example, as a sirocco fan and is connected to a motor 36. The second fan 35 is rotationally driven by the driving force of the motor 36. When the second fan 35 is rotationally driven, an airflow is generated from the outdoor air intake 14 toward the inside of the case 2. As a result, outside air from the external area 5 is drawn in from the outdoor air intake 14. The outside air drawn into the inside of the case 2 is then heat-exchanged in the condenser 24 and exhausted from the outdoor exhaust port 16. In this embodiment, as shown in Figures 1 and 6, the outdoor exhaust port 16 and the second fan 35 are connected by piping 44. Therefore, the warm air exhausted from the second fan 35 passes through piping 44 and is guided to the outdoor exhaust port 16.

[0040] Next, the compressor 20, evaporator 22, and condenser 24 that constitute the refrigeration cycle in the integrated air conditioning system 1 will be described with reference to Figure 1. In this embodiment, the case in which the evaporator 22 and condenser 24 form a fin-tube type heat exchanger 26 in which copper pipes are passed through fins made of aluminum or the like, which has good thermal conductivity, will be described.

[0041] The compressor 20 is formed by a pump and is located below the case 2. The compressor 20 is intended to compress the refrigerant in the heat exchanger 26 into a high-temperature, high-pressure gas. The high-temperature, high-pressure refrigerant compressed by the compressor 20 is sent to the condenser 24.

[0042] The condenser 24 has fins made of aluminum or a similar material with good thermal conductivity, and copper pipes through which the refrigerant flows pass. The condenser 24 condenses (liquefies) the high-temperature, high-pressure refrigerant compressed by the compressor 20 by releasing heat. In addition, outside air is supplied to the condenser 24 by the second fan 35. This allows for heat exchange with the refrigerant, and the heat released from the refrigerant is cooled by the outside air. The outside air also absorbs heat and becomes warm air, which is then exhausted from the outdoor exhaust port 16. On the other hand, the refrigerant condensed in the condenser 24 passes through an expansion valve (not shown), where its pressure decreases and its boiling point drops. As a result, the refrigerant is converted into a low-temperature, low-pressure liquid and sent to the evaporator 22.

[0043] The evaporator 22, like the condenser 24, has fins made of aluminum or a similar material with good thermal conductivity, and copper pipes for circulating the refrigerant pass through these fins. The evaporator 22 is designed to evaporate (vaporize) the refrigerant, which has become a low-temperature, low-pressure liquid. As the refrigerant evaporates, heat is removed from the evaporator 22, causing its temperature to drop. In addition, room air is supplied to the evaporator 22 by the first fan 30. This allows for heat exchange with the refrigerant, and the air drawn in from the room is cooled by the evaporator 22. The cooled air is then blown out as cold air from the room outlet 12. The above is one embodiment of the refrigeration cycle in the integrated air conditioning system 1 of the present invention.

[0044] Next, the intake and exhaust ducts 50 mounted on the integrated air conditioning system 1 of the present invention will be described with reference to Figures 2 and 3. Please note that in Figure 3, the mounting portion 60 is omitted.

[0045] The intake and exhaust duct 50 is formed by integrating an intake duct 51 and an exhaust duct 52. In this embodiment, the intake duct 51 forms the outer cylinder of the intake and exhaust duct 50 and also forms the outer duct (hereinafter, the intake duct 51 will also be referred to as the outer duct 51). One end of the intake and exhaust duct 50 is connected to a connected adapter (not shown) of the case 2, and the other end is connected to a mounting portion 60 (see Figure 2) that communicates with the external area 5.

[0046] The intake duct 51 is formed, for example, as a cylindrical bellows, and can be expanded and contracted within a predetermined range, as well as bent. One end of the intake duct 51 can be connected to the outdoor air intake port 14. Specifically, one end of the intake / exhaust duct 50 is formed as a connection adapter (not shown), which can be connected to the adapter on the case 2 with a single touch. Furthermore, the connection adapter of the intake / exhaust duct 50 is integrally formed with the connection adapters of the intake duct 51 and the exhaust duct 52. Therefore, by connecting the connection adapter of the intake / exhaust duct 50 to the adapter on the case 2, one end of the intake duct 51 is connected to the outdoor air intake port 14. As will be described in detail later, the other end of the intake duct 51 is in communication with the external area 5 via the mounting part 60. As a result, the intake duct 51 can draw outside air from the external area 5 into the outdoor air intake port 14 (inside the case 2).

[0047] The exhaust duct 52 is formed as a cylindrical bellows and can expand and contract within a predetermined range, as well as bend. Furthermore, the exhaust duct 52 forms the inner cylinder and inner duct of the intake and exhaust duct 50 (hereinafter, the exhaust duct 52 will also be referred to as the inner duct 52). In other words, the intake and exhaust duct 50 has a double structure consisting of the inner duct 52 and the outer duct 51. As a result, the exhaust duct 52 can expand and contract and bend integrally with the outer duct 51.

[0048] One end of the exhaust duct 52 can be connected with a single touch to the adapter on the outdoor exhaust port 16 by connecting the connection adapter of the intake / exhaust duct 50 to the adapter on the case 2. The other end of the exhaust duct 52 is in communication with the external area 5 via the mounting part 60, similar to the intake duct 51. As a result, the exhaust duct 52 can exhaust the warm air exhausted from the outdoor exhaust port 16 towards the external area 5.

[0049] Thus, in the intake and exhaust duct 50 of this embodiment, the intake duct 51 and the exhaust duct 52 are integrated and connected to the adapters of the outdoor intake port 14 and the outdoor exhaust port 16. Therefore, the connection of the intake and exhaust duct 50 is easy.

[0050] Furthermore, as shown in Figure 3, in this embodiment, an insulating layer 53 is provided so as to cover the outer circumference of the exhaust duct 52. The insulating layer 53 is formed of, for example, a vacuum jacket or insulating material, and is designed to suppress heat exchange between the warm air in the exhaust duct 52 and the outside air in the intake duct 51. As a result, the temperature rise of the outside air passing through the intake duct 51 (outer duct 51) is suppressed, and the outside air is supplied to the condenser 24 while maintaining its temperature. Therefore, the insulating layer 53 can suppress a decrease in the efficiency of heat exchange in the refrigeration cycle.

[0051] As shown in Figure 2, the mounting portion 60 is connected to one end of the intake / exhaust duct 50 (opposite the connection end of the case 2). The mounting portion 60 is provided to fix the intake / exhaust duct 50 to the fixing frame 6 of the window frame 4.

[0052] Figure 4 is a partially cutaway perspective view of the mounting portion 60, and Figure 5 is a longitudinal cross-sectional view of Figure 4. Note that the heat insulating layer 53 is omitted in Figures 4 and 5. Also note that Figures 4 and 5 are simplified to aid in understanding the invention. The mounting portion 60 has an inner cylinder 65 connected to the exhaust duct 52 (inner duct 52) ​​and an outer cylinder 61 connected to the intake duct 51 (outer duct 51).

[0053] The outer cylinder 61 is positioned radially outward from the inner cylinder 65 at a predetermined distance. The outer cylinder 61 has an outer duct connection portion 61C at one end, allowing the intake duct 51 (outer duct 51) to be attached and detached via the outer duct connection portion 61C. The outer cylinder 61 also has an outer duct intake port 61A at the other end, which communicates with the external area 5. This prevents negative pressure from forming inside the case 2, ensuring that intake and exhaust are reliably separated. Furthermore, it improves the cooling efficiency of the integrated air conditioning unit 1. A flange portion 61B is formed on the outer duct connection portion 61C side of the outer cylinder 61. The outer cylinder 61 can be fixed to the window frame 4 by fixing the flange portion 61B to the fixing frame 6. Note that the mounting portion 60 is not limited to fixing by the flange portion 61B, and can be fixed to the window frame 4, fixing frame 6, etc., using various means.

[0054] The inner cylinder 65 is provided with an appropriate inner duct connection portion 65C at one end, and the exhaust duct 52 can be connected via the inner duct connection portion 65C. The inner cylinder 65 also has an extension portion 65B formed at the other end. Furthermore, an insulating layer 53 is formed on the outer circumference of the inner cylinder 65. The inner cylinder 65 itself may be made of insulating material, or it may be configured without the insulating layer 53.

[0055] The extension portion 65B extends along the axial direction of the inner cylinder 65, and its tip is formed to extend beyond the open end (outer duct intake port 61A) of the outer cylinder 61. The extension portion 65B has an inner duct exhaust port 65A that communicates with the external region 5 at its tip. In other words, the inner duct exhaust port 65A and the outer duct intake port 61A are arranged to be separated from each other. Therefore, the extension portion 65B can separate the inner duct exhaust port 65A and the outer duct intake port 61A. As a result, the extension portion 65B can prevent warm air immediately after exhaust from being drawn in from the intake duct 51 (outer duct 51).

[0056] Furthermore, an outer flange portion 66 is provided at the tip of the extension portion 65B, projecting radially outward from the inner cylinder 65. The outer flange portion 66 is positioned so that its forming surface faces the open end of the outer cylinder 61 at a distance. As a result, as shown by the arrows in Figures 4 and 5, the outer flange portion 66 can guide outside air into the interior of the outer cylinder 61 along its forming surface. The outer flange portion 66 also acts as a partition wall separating the outer duct intake port 61A and the inner duct exhaust port 65A. In other words, the outer flange portion 66 can suppress the mixing of warm air flowing through the inner cylinder 65 and outside air flowing through the outer cylinder 61. This improves the cooling efficiency of the room.

[0057] The above describes the configuration of the integrated air conditioning system 1 according to one embodiment of the present invention. Next, the effects and advantages of the integrated air conditioning system 1 of the present invention will be explained in detail.

[0058] As described above, the integrated air conditioning unit 1 has an intake duct 51 and an exhaust duct 52, and separates the first air supply path 40 for indoor intake and exhaust and the second air supply path 42 for outdoor intake and exhaust. Therefore, indoor intake and exhaust and outdoor intake and exhaust can be performed independently. Consequently, the integrated air conditioning unit 1 described above can suppress the mixing of cooled air with exhaust and discharge from the exhaust duct, thereby improving cooling efficiency.

[0059] Furthermore, since the intake duct 51 and exhaust duct 52 of the integrated air conditioning unit 1 described above are integrally formed, these ducts can be made smaller. As a result, the integrated air conditioning unit 1 described above can be expected to have a smaller package size, which in turn can reduce transportation costs. In addition, since the intake duct 51 and exhaust duct 52 of the integrated air conditioning unit 1 described above are integrated, it is easy to attach them to the main unit or to window frames, etc., during installation.

[0060] Furthermore, in the integrated air conditioning system 1 of the present invention described above, the intake and exhaust ducts 50 are formed in a double structure by an inner duct 52 (exhaust duct 52) ​​and an outer duct 51 (intake duct 51). Therefore, in the integrated air conditioning system 1 described above, the intake duct 51 and the exhaust duct 52 can be integrated into a single intake and exhaust duct 50. As a result, the integrated air conditioning system 1 described above can reduce the space required for installing the intake duct 51 and the exhaust duct 52. Therefore, the integrated air conditioning system 1 described above can improve the versatility of installation. In addition, since the intake duct 51 and the exhaust duct 52 are integrated into a single intake and exhaust duct 50 in the integrated air conditioning system 1 described above, the packaging size of the ducts can be reduced. As a result, the integrated air conditioning system 1 described above can reduce transportation costs. Furthermore, the integrated air conditioning system 1 described above can also improve the ease of installation of the intake and exhaust ducts 50.

[0061] Furthermore, in the integrated air conditioning system 1 described above, the exhaust duct 52 is configured as an inner duct 52, and the intake duct 51 is configured as an outer duct 51. Therefore, the integrated air conditioning system 1 described above can suppress the release of heat into the room from the warm air passing through the inner duct 52. In other words, the heat of the warm air passing through the inner duct 52 is contained by the outside air (low-temperature gas) passing through the outer duct 51. Therefore, the integrated air conditioning system 1 described above can improve the cooling efficiency of the room.

[0062] Furthermore, the integrated air conditioning unit 1 described above has a connection between the outdoor exhaust port 16 and the second fan 35 via piping 44. This allows the integrated air conditioning unit 1 to reliably guide the warm air discharged from the second fan 35 to the outdoor exhaust port 16. As a result, the integrated air conditioning unit 1 can suppress the mixing of the warm air discharged from the second fan 35 with the outside air on the intake side. This further improves the cooling efficiency of the room.

[0063] The above describes the configuration and operation and effects of the integrated air conditioning unit 1 according to one embodiment of the present invention. Next, a modified example of the mounting portion 60 will be described below with reference to Figure 7.

[0064] ≪Variations≫ In this modified example, the configuration is the same as the embodiment described above, except that an extension pipe 67 is provided at the tip of the extension portion 65B of the inner cylinder 65. Therefore, the description of the identical parts will be omitted. Also, please note that the same reference numerals are used for identical components as in the embodiment described above.

[0065] The extension pipe 67 is provided at the tip of the extension section 65B. In other words, the extension pipe 67 extends the inner cylinder 65 in the axial direction. Therefore, the extension pipe 67 can further separate the inner duct exhaust port 65A from the outer duct intake port 61A. This further improves the cooling efficiency of the room.

[0066] The above describes the configuration of an embodiment and modified version of the integrated air conditioning device 1 of the present invention. However, the present invention is not limited to the embodiments and modified versions described above, and appropriate modifications can be made within the scope of the invention.

[0067] In this embodiment, the outdoor air intake 14 and outdoor exhaust 16 are located on the rear side of the case 2, but this is not limited to this configuration, and the outdoor air intake 14 and outdoor exhaust 16 can be located in various positions. For example, the outdoor air intake 14 and outdoor exhaust 16 may be located on the side of the case 2. Also, in this embodiment, the indoor air intake 10 is located on the rear side of the case 2 and the indoor air outlet 12 is located on the front side of the case 2, but the indoor air intake 10 and indoor air outlet 12 can be located in various positions. For example, the indoor air intake 10 may be located on the side of the case 2. Also, the indoor air outlet 12 may be located on the top side of the case 2. Furthermore, multiple indoor air intakes 10 and indoor air outlets 12 may be provided. In addition, various shapes and sizes of case 2 can be used.

[0068] Furthermore, the arrangement of the compressor 20, evaporator 22, and condenser 24 is not limited to this embodiment and can be arranged in various positions. In addition, although this embodiment illustrates the case in which a refrigeration cycle is configured, the integrated air conditioning system of the present invention can also be used as a heating system by reversing the compressor 20, evaporator 22, condenser 24, intake duct 51, exhaust duct 52, etc.

[0069] Furthermore, the materials used for the intake duct 51 and exhaust duct 52 are not limited to cylindrical or bellows-shaped materials, but can be made from a variety of materials. Also, the shape and size of the intake duct 51 and exhaust duct 52 are not limited to those of this embodiment, and can be made from a variety of shapes and sizes. In this embodiment, the intake duct 51 and exhaust duct 52 are formed as a single tube, but the intake duct 51 and exhaust duct 52 may be formed by connecting separately formed parts. In addition, the first air supply path 40 and the second air supply path 42 can be made from a variety of shapes and sizes. In this embodiment, sirocco fans are exemplified as the first fan 30 and the second fan 35, but the integrated air conditioning device 1 of the present invention is not limited to these, and can utilize fans of various types.

[0070] In this embodiment, the inner duct 52 (exhaust duct 52) ​​and the outer duct 51 (intake duct 51) are formed in a double structure, but the integrated air conditioning system of the present invention is not limited to this. That is, the exhaust duct 52 and the intake duct 51 can be integrated in various forms. For example, the exhaust duct 52 and the intake duct 51 may be integrated by bonding them together. Specifically, the exhaust duct 52 and the intake duct 51 may be formed in a triangular or rectangular shape in cross-section, and the outer surfaces of the exhaust duct 52 and the intake duct 51 may be integrated by bonding them together.

[0071] Furthermore, in this embodiment, an example is shown in which the inner duct 52 is enclosed within the outer duct 51 and the inner duct 52 is not supported by the outer duct 51. However, the space between the outer duct 51 and the inner duct 52 may be supported by a spacer. With this configuration, a predetermined gap is formed between the outer duct 51 and the inner duct 52, and the airflow of outside air supplied to the heat exchanger 26 is stabilized. This stabilizes the cooling efficiency.

[0072] Furthermore, in this embodiment, the intake duct 51 is formed as an outer duct 51 and the exhaust duct 52 is formed as an inner duct 52, but the integrated air conditioning system of the present invention is not limited to this. For example, the intake duct 51 may be formed as an inner duct 52 and the exhaust duct 52 may be formed as an outer duct 51.

[0073] Furthermore, in this embodiment, an insulating layer 53 is provided between the inner duct 52 and the outer duct 51, but the insulating layer 53 may be provided as appropriate, and a configuration without an insulating layer 53 is also possible. In addition, various insulating structures can be used for the insulating layer 53. Also, in this embodiment, the insulating layer 53 is provided independently of the inner duct 52, but the inner duct 52 itself may be formed from insulating material.

[0074] In this embodiment, a mounting portion 60 is provided on one end of the intake / exhaust duct 50. However, the mounting portion 60 may be provided only if necessary, and the intake / exhaust duct 50 may be configured without a mounting portion 60. Furthermore, the shape and size of the mounting portion 60 (including the flange portion 61B) can be appropriately changed according to the shape and size of the window frame 4. In this embodiment, the mounting portion 60 is shown as being fixed to the fixed frame 6 by the flange portion 61B, but the mounting portion 60 is not limited to the flange portion 61B and can be fixed to the window 3 or fixed frame 6 by various means. Furthermore, an extension portion 65B of the mounting portion 60 may be provided only if necessary, and a configuration without an extension portion 65B is also possible. In addition, various shapes and sizes of extension portions 65B can be used.

[0075] In this embodiment, an outer flange 66 is provided on the extension portion 65B, but the outer flange 66 may be provided as appropriate, taking into consideration the installation space, etc. For example, the integrated air conditioning unit 1 described above may not have an outer flange 66. In such a case, it is desirable that the outer duct intake port 61A and the inner duct exhaust port 65A are spaced apart from each other. Also, in this embodiment, the outer flange 66 is formed in an annular shape, but the shape and size of the outer flange 66 may be changed as appropriate. In addition, the extension pipe 67 may be provided as appropriate, and the shape and size of the extension pipe 67 may also be changed as appropriate. Also, in this embodiment, the outdoor exhaust port 16 and the second fan 35 are connected by piping 44, but the piping 44 may be provided as needed, and the unit may not have piping 44.

[0076] The above describes embodiments of the integrated air conditioning device of the present invention. However, the present invention is not limited to those exemplified in the above embodiments and modifications, and it will be readily apparent to those skilled in the art that other embodiments may exist in the spirit and nature of the teachings, without departing from the scope of the claims. [Industrial applicability]

[0077] The integrated air conditioning system of the present invention can be used in various locations, both indoors and outdoors. Furthermore, the integrated air conditioning system of the present invention is particularly suitable for use in locations where there are limitations on the installation of separate-type air conditioning systems.
