Description

This invention relates to an integrated air conditioning system.

Conventionally, two types of air conditioning systems are known: separate-type air conditioners (also called air conditioners) with separate indoor and outdoor units, and integrated-type air conditioners (also called portable coolers) that incorporate a heat exchanger (evaporator and condenser). The latter, integrated-type air conditioners, are used when separate-type air conditioners cannot be installed due to room layout or other reasons, or when a quick and localized cooling solution is desired. Integrated-type air conditioners (equivalent to integrated air conditioning units) incorporate a low-capacity compressor and utilize a refrigeration cycle (for example, Patent Document 1).

Patent No. 4354318

Incidentally, the integrated air conditioning system described in Patent Document 1 has a structure that uses indoor air for heat exchange, and since the cooled air is also exhausted outside, there is a problem of reduced cooling efficiency. Furthermore, the integrated air conditioning system described in Patent Document 1 is designed so that negative pressure is created inside the case as indoor air is discharged. Therefore, the integrated air conditioning system described in Patent Document 1 has the problem of drawing in warm air from outside, which reduces cooling efficiency.

Furthermore, if two ducts—an exhaust duct and an intake duct—are installed to address the aforementioned problems, the installation space required for the ducts becomes bulky. Additionally, the large space needed to accommodate the ducts leads to higher transportation costs.

Therefore, the present invention aims to provide an integrated air conditioning system that can improve cooling efficiency and be compactly constructed.

(1) The integrated air conditioning system of the present invention, provided to solve the above-mentioned problems, comprises a case having an indoor intake port, an indoor outlet port, an outdoor intake port, and an outdoor exhaust port, the case having a compressor, evaporator, and condenser that constitute a refrigeration cycle inside, the outdoor intake port 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, This system exhausts warm air from the outdoor exhaust port toward the external 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 first airflow path contains the evaporator and the first fan, and the second airflow path contains the condenser and the second fan. The intake duct and the exhaust duct are integrally formed to create an intake and exhaust duct.

The integrated air conditioning system described above has an intake duct and an exhaust duct, and separates the first airflow path for indoor intake and exhaust from the second airflow path for outdoor intake and exhaust. Therefore, indoor and outdoor intake and exhaust can be performed independently. Furthermore, this integrated air conditioning system can improve cooling efficiency by preventing cooled air from mixing with the exhaust air and being discharged through the exhaust duct.

Furthermore, since the intake and exhaust ducts of the aforementioned integrated air conditioning unit are integrally formed, these ducts can be miniaturized. Therefore, the aforementioned integrated air conditioning unit can be expected to have a smaller package size, which in turn can reduce transportation costs. Additionally, because the intake and exhaust ducts of the aforementioned integrated air conditioning unit are integrated, installation to the unit body or window frames, etc., is easier.

Furthermore, the integrated air conditioning system described above has an intake duct and an exhaust duct, with the intake duct communicating with the outside environment. Therefore, in this integrated air conditioning system, negative pressure inside the case is suppressed, and intake and exhaust are reliably separated. Consequently, this integrated air conditioning system can improve cooling efficiency.

(2) The integrated air conditioning system of the present invention described above has an intake and exhaust duct, each having a cylindrical inner duct and an outer duct, wherein one of the intake duct and the exhaust duct is composed of the inner duct, and the other of the intake duct and the exhaust duct is composed of the outer duct, and the inner duct and the outer duct form a double structure.

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 offers improved versatility in installation. Furthermore, because the intake and exhaust ducts are integrated into a single duct, the packaging size of the duct can be reduced. This reduces transportation costs. Additionally, the integrated air conditioning system improves the ease of installation of the intake and exhaust ducts.

(3) In the integrated air conditioning system of the present invention described above, it is preferable that the exhaust duct is configured as the inner duct and the intake duct is configured as the outer duct.

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 from the warm air passing through the inner duct. Therefore, the integrated air conditioning system described above can improve the cooling efficiency of the room.

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

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.

(5) In the integrated air conditioning system of the present invention described above, the intake and exhaust ducts have mounting portions for fixing the opening end on the side of the external region, and the mounting portions have 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.

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

(6) The integrated air conditioning device of the present invention described above has an inner cylinder connected to the inner duct and an outer cylinder connected to the outer duct, wherein the inner cylinder preferably has an extended portion formed so that its tip extends beyond the open end of the outer cylinder.

The integrated air conditioning system described above has an extension section, allowing the open end of the inner cylinder (inner duct) and the open end of the outer cylinder (outer duct) to be separated. Therefore, the integrated air conditioning system can suppress the mixing of warm air discharged from the inner cylinder and outside air drawn in from the outer cylinder. This allows the integrated air conditioning system to further improve the cooling efficiency of the room.

(7) In the integrated air conditioning device of the present invention described above, the extension portion is preferably provided with an outer flange portion that protrudes radially outward from the inner cylinder.

The integrated air conditioning system described above, with this configuration, can suppress the mixing of warm air discharged from the inner duct (exhaust duct) and outside air drawn in from the outer duct (intake duct). In other words, the outer flange acts as a partition wall separating the exhaust port of the inner duct from the intake port of the outer duct. This allows the integrated air conditioning system to improve the cooling efficiency of the room.

(8) The integrated air conditioning device of the present invention described above may be provided with an extension pipe in the extension section that extends the inner cylinder in the axial direction.

The integrated air conditioning system described above, with this configuration, can further separate the exhaust port of the inner duct from the intake port of the outer duct. This allows the integrated air conditioning system to further improve the cooling efficiency of the room.

(9) In the integrated air conditioning system of the present invention described above, it is preferable that the outdoor exhaust port and the second fan are connected by piping.

The integrated air conditioning system described above, with this configuration, can reliably guide the warm air discharged from the second fan to the outdoor exhaust vent. Therefore, the integrated air conditioning system can suppress the mixing of the warm air discharged from the second fan with the outside air on the intake side. As a result, the integrated air conditioning system can further improve the cooling efficiency of the room.

According to the present invention, it is possible to provide an integrated air conditioning system that can improve cooling efficiency and be formed compactly.

This is a partially cutaway perspective view of an integrated air conditioning unit according to one embodiment of the present invention, as seen from the rear side. This is a partially cutaway perspective view of a mounting portion constituting the integrated air conditioning system of the present invention. This is a longitudinal cross-sectional view of Figure 4. This is an explanatory diagram of an integrated air conditioning system relating to one embodiment of the present invention. This is a longitudinal cross-sectional view relating to a modified example of a mounting portion constituting the integrated air conditioning device of the present invention.

One embodiment of the integrated air conditioning system 1 of the present invention will be described in detail below with reference to Figures 1 to 6. Please note that the dimensions in each figure may differ from the actual proportions for the sake of explanation.

As shown in Figures 1 to 3, the integrated air conditioning system 1 of the present invention has its main unit housed in a case 2. Furthermore, an intake and exhaust duct 50, which has an intake duct 51 and an exhaust duct 52 integrally formed with it, is connected to the rear side of the case 2.

As shown in Figure 1, Case 2 is formed as a vertically elongated box and includes 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.

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

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.

As shown in Figure 1, a first airflow path 40 is formed between the indoor intake port 10 and the indoor outlet port 12. The first airflow path 40 contains an evaporator 22 and a first fan 30. The first airflow path 40 is separated by a partition wall with an insulated outer perimeter, forming a passage for circulating air drawn in from the indoor intake port 10 towards the indoor outlet port 12.

The first fan 30 is, for example, a sirocco fan, and a motor 31 is connected to it. 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 towards 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.

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 connection 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, 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. Furthermore, the outdoor air intake port 14 is provided with a filter (not shown), which is designed to prevent dust and foreign matter from entering the case 2.

The outdoor exhaust port 16 is formed in a cylindrical shape and is located inside the outdoor intake port 14. That is, 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.

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, forming a passage for circulating outside air drawn in from the outdoor air intake 14 towards the outdoor exhaust 16.

The second fan 35 is, for example, a sirocco fan, and a motor 36 is connected to it. 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 through the outdoor air intake 14. The outside air drawn into the inside of the case 2 undergoes heat exchange in the condenser 24 and is then 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.

Next, the compressor 20, evaporator 22, and condenser 24, which constitute the refrigeration cycle in the integrated air conditioning system 1, will be described with reference to Figure 1. In this embodiment, the case where 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 other material with good thermal conductivity, will be described.

The compressor 20 is formed by a pump and is located below the case 2. The compressor 20 compresses 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.

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 condenser 24 condenses (liquefies) the high-temperature, high-pressure refrigerant compressed by the compressor 20 by releasing heat. Outside air is also supplied to the condenser 24 by the second fan 35. This facilitates heat exchange with the refrigerant, where the heat released from the refrigerant is cooled by the outside air. The outside air absorbs heat and becomes warm air, which is then exhausted through the outdoor exhaust port 16. Meanwhile, the refrigerant condensed in the condenser 24 passes through an expansion valve (not shown), where its pressure decreases and its boiling point drops. This converts the refrigerant into a low-temperature, low-pressure liquid, which is then sent to the evaporator 22.

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. Furthermore, room air is supplied to the evaporator 22 by the first fan 30. This facilitates 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 describes one embodiment of the refrigeration cycle in the integrated air conditioning system 1 of the present invention.

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. Note that in Figure 3, the mounting portion 60 is omitted.

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 both the outer cylinder and the outer duct of the intake and exhaust duct 50 (hereinafter, the intake duct 51 will also be referred to as the outer duct 51). Furthermore, one end of the intake and exhaust duct 50 is connected to a connection adapter (not shown) of the case 2, while the other end is connected to a mounting portion 60 (see Figure 2) that communicates with the external region 5.

The intake duct 51 is formed, for example, as a cylindrical bellows, and is expandable and contractible within a predetermined range, as well as being able to be 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 communicates with the external area 5 via the mounting portion 60. This allows the intake duct 51 to draw outside air from the external area 5 into the outdoor air intake port 14 (inside the case 2).

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/exhaust duct 50 (hereinafter, the exhaust duct 52 will also be referred to as the inner duct 52). In other words, the intake/exhaust duct 50 has a double-layered structure consisting of the inner duct 52 and the outer duct 51. This allows the exhaust duct 52 to expand and contract and bend integrally with the outer duct 51.

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, like the intake duct 51, communicates with the external area 5 via the mounting portion 60. This allows the exhaust duct 52 to exhaust the warm air exhausted from the outdoor exhaust port 16 towards the external area 5.

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.

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. This suppresses the temperature rise of the outside air passing through the intake duct 51 (outer duct 51), 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.

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

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).

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 reliable separation of intake and exhaust air. Furthermore, it improves the cooling efficiency of the integrated air conditioning system 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; it can be fixed to the window frame 4, fixing frame 6, etc., using various means.

The inner cylinder 65 has an appropriate inner duct connection portion 65C at one end, through which the exhaust duct 52 can be connected. The inner cylinder 65 also has an extended portion 65B at the other end. Furthermore, a heat insulating layer 53 is formed on the outer circumference of the inner cylinder 65. Note that the inner cylinder 65 itself may be made of heat insulating material, or the heat insulating layer 53 may not be provided.

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. That is, the inner duct exhaust port 65A and the outer duct intake port 61A are arranged to be separated. Therefore, the extension portion 65B can separate the inner duct exhaust port 65A and the outer duct intake port 61A. This allows the extension portion 65B to suppress the intake of warm air immediately after exhaust from being drawn into the intake duct 51 (outer duct 51).

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. Therefore, as shown by the arrows in Figures 4 and 5, the outer flange portion 66 can guide outside air into 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 from 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.

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

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 can be performed independently. Consequently, the integrated air conditioning unit 1 can suppress the mixing of cooled air with the exhaust and discharge from the exhaust duct, thereby improving cooling efficiency.

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 miniaturized. Therefore, the integrated air conditioning unit 1 is expected to have a smaller packaging size, which in turn is expected to reduce transportation costs. Also, because the intake duct 51 and exhaust duct 52 of the integrated air conditioning unit 1 are integrated, installation to the main unit or to window frames, etc., is easily facilitated.

Furthermore, the integrated air conditioning system 1 of the present invention described above has a double-layered intake and exhaust duct 50, consisting of an inner duct 52 (exhaust duct 52) and an outer duct 51 (intake duct 51). Therefore, the integrated air conditioning system 1 can integrate the intake duct 51 and the exhaust duct 52 into a single intake and exhaust duct 50. This allows the integrated air conditioning system 1 to reduce the space required for installing the intake duct 51 and the exhaust duct 52. Thus, the integrated air conditioning system 1 can improve the versatility of installation. Also, because the intake duct 51 and the exhaust duct 52 are integrated into a single intake and exhaust duct 50, the packaging size of the duct can be reduced. This reduces the transportation costs of the integrated air conditioning system 1. Furthermore, the integrated air conditioning system 1 can also improve the ease of installation of the intake and exhaust duct 50.

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 can suppress the release of heat from the warm air passing through the inner duct 52 into the room. 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 can improve the cooling efficiency of the room.

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 ensures that the integrated air conditioning unit 1 reliably guides the warm air discharged from the second fan 35 to the outdoor exhaust port 16. Therefore, 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. As a result, the integrated air conditioning unit 1 can further improve the cooling efficiency of the room.

The above describes the configuration and operation and effects of the integrated air conditioning system 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.

≪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 extended 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.

The extension pipe 67 is provided at the tip of the extension section 65B. That is, 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.

The above describes the configuration of the integrated air conditioning system 1 of the present invention, including embodiments and modified examples. However, the present invention is not limited to the embodiments and modified examples described above, and appropriate modifications can be made within the scope of the invention.

In this embodiment, the outdoor air intake 14 and outdoor exhaust 16 are located on the rear side (rear side) of the case 2, but this is not limited to this configuration. 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. The indoor air outlet 12 may also be located on the top side of the case 2. Furthermore, multiple indoor air intakes 10 and indoor air outlets 12 may be provided. Also, various shapes and sizes of case 2 can be used.

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. While this embodiment illustrates the configuration of a refrigeration cycle, 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.

Furthermore, the materials used for the intake duct 51 and exhaust duct 52 are not limited to cylindrical or bellows-shaped materials; various materials can be used. Also, the shape and size of the intake duct 51 and exhaust duct 52 are not limited to those of this embodiment; various shapes and sizes can be adopted. In this embodiment, the intake duct 51 and exhaust duct 52 are formed as a single tube, but they may be formed by connecting separately formed sections. The first airflow path 40 and the second airflow path 42 can be formed in various 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 system 1 of the present invention is not limited to these, and various types of fans can be used.

In this embodiment, the inner duct 52 (exhaust duct 52) and the outer duct 51 (intake duct 51) are formed in a double-layer 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.

Furthermore, in this embodiment, 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. This configuration creates a predetermined gap between the outer duct 51 and the inner duct 52, stabilizing the airflow of outside air supplied to the heat exchanger 26. This stabilizes the cooling efficiency.

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. However, 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.

Furthermore, in this embodiment, an insulating layer 53 is provided between the inner duct 52 and the outer duct 51. However, the insulating layer 53 may be provided as appropriate, and a configuration without an insulating layer 53 is also possible. 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.

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 as needed, and the intake/exhaust duct 50 may be configured without a mounting portion 60.
