Summary of the Invention

Problems to be Solved by the Invention

[0004] As forms of air conditioning equipment installed in a building, for example, there are a package cooler provided with a refrigeration cycle composed of a compressor, a condenser, etc. inside the machine, a fan coil unit that passes chilled water produced by a chiller through a coil inside the machine, and various other types. Also, as forms of airflows in the air-conditioned space, there are those that forcefully blow out air from an air supply port to forcibly circulate the indoor air, and displacement air conditioning that blows out low-temperature air at a low speed so that the indoor temperature stratification is maintained, etc.

[0005] Most commercially available air conditioning equipment is in a form that blows out air from an air supply port provided at an appropriate location on the housing. Therefore, for example, when it is desired to realize displacement air conditioning with a ceiling-mounted air conditioner that is widely distributed in the market and can be obtained relatively inexpensively, it is necessary to separately prepare an air supply unit for displacement air conditioning that needs to be arranged near the floor surface, and connect the ceiling-mounted air conditioner arranged near the ceiling and the air supply unit arranged near the floor surface with a duct, making it difficult to reduce on-site work.

[0006] The present invention has been made in view of the above problems, and aims to provide an air conditioning module and a method for installing an air conditioning module that facilitates the installation of an air supply unit located near the floor and a ceiling-mounted air conditioner connected thereto. [Means for solving the problem]

[0007] To solve the above problems, in this invention, a ceiling-side frame that holds a ceiling-mounted air conditioner from the inside is attached to the upper part of a floor-side frame that can house an air supply unit located near the floor surface.

[0008] More specifically, the present invention relates to an air conditioning module installed on the floor surface of a space to be air-conditioned, comprising: a floor-side frame capable of housing an air supply unit located near the floor surface; and a ceiling-side frame that internally holds a ceiling-mounted air conditioner connected to the air supply unit and can be attached to the upper part of the floor-side frame.

[0009] Here, the term "air supply unit located near the floor" includes not only units directly installed on the floor, but also units indirectly installed on the floor. Furthermore, the term "module" is not limited to a state in which the floor-side frame and ceiling-side frame are integrated, but also includes a state in which the floor-side frame and ceiling-side frame are separate.

[0010] With the above air conditioning module, by simply attaching the ceiling-side frame to the top of the floor-side frame installed on the floor, the air supply unit installed near the floor can be suspended from the ceiling. The ceiling-mounted air conditioner, designed as a prerequisite, can be fixed in place. Therefore, even in cases where, for example, displacement air conditioning is to be implemented using a relatively inexpensive ceiling-mounted air conditioner, the installation of the displacement air supply unit, which needs to be installed near the floor, and the ceiling-mounted air conditioner, designed for suspension from the ceiling, can be completed with a relatively simple operation of fixing the ceiling-side frame to the top of the floor-side frame. Thus, it can be said that the above air conditioning module makes on-site work extremely simple.

[0011] Furthermore, the ceiling-side frame may also internally hold the air intake unit connected to the ceiling-mounted air conditioner. This allows for the installation of both the ceiling-mounted air conditioner and the air intake unit with the relatively simple task of fixing the ceiling-side frame to the top of the floor-side frame.

[0012] Furthermore, the ceiling-mounted air conditioner has an overall rectangular shape and has an intake port on the side of the rectangular shape to which the intake unit is connected. The ceiling frame may hold the ceiling-mounted air conditioner in a position where the intake port faces directly to the side relative to the front direction, which is the direction in which the supply air unit is blown out. This makes it easier to bring the center of gravity of the ceiling frame closer to directly above the floor frame when it is mounted on top of the floor frame.

[0013] Furthermore, the air supply unit is located on the floor frame, and the ceiling-mounted air conditioner... Suction port The air supply unit is positioned slightly in the opposite direction from the direction it is facing, and the floor-side frame may have shelves in areas where the air supply unit is not located. This allows for effective use of the empty space on the floor-side frame.

[0014] Furthermore, the floor-side frame is a frame erected so that its back side is along the wall surface of the space to be air-conditioned, and the ceiling-side frame may be attached to the top of the floor-side frame so as to protrude toward the front of the floor-side frame. This allows the floor-side frame to be installed close to the wall surface, thus preventing the air conditioning module from becoming a physical obstacle.

[0015] Furthermore, the air supply unit may be a displacement air conditioning unit with multiple circular air supply ports on its front, each having guide fins inside that impart a swirling component to the low-temperature air supplied from the ceiling-mounted air conditioner. This makes it possible to achieve displacement air conditioning without drafts while maintaining temperature stratification within the air-conditioned space.

[0016] Further, the present invention can also be grasped from the aspect of a method. For example, the present invention is a method for installing an air conditioning module described above in a building at a construction site, which includes an assembly work process of assembling the floor side frame and the ceiling side frame outside the construction site respectively, and the floor side frame and the ceiling side frame of a transportation process of transporting to the construction site, and an attachment process of attaching the ceiling side frame to the upper part of the floor side frame after fixing the floor side frame to the floor surface. It may be a method having these steps.

Advantages of the Invention

[0017] With the above air conditioning module and the method for installing the air conditioning module, the installation of the air supply unit arranged near the floor surface and the ceiling-suspended air conditioner connected thereto becomes easy.

Embodiments for Carrying Out the Invention

[0019] The embodiments of the present invention will be described below. The embodiments shown below are examples of embodiments of the present invention and do not limit the technical scope of the present invention to the following embodiments.

[0020] Figure 1 is a view of the air conditioning module according to the embodiment, seen from diagonally above. Figure 2 is a view of the air conditioning module according to the embodiment, seen from diagonally below. In Figure 1, the air conditioning module 1 is shown erected from the floor surface F with its back side aligned with the wall surface W of the space to be air-conditioned S. In Figure 2, the floor surface F is shown as seen through from below the floor surface F on which the air conditioning module 1 is installed.

[0021] As shown in Figures 1 and 2, the air conditioning module 1 is installed on the floor surface F of the space to be air-conditioned S, and comprises a ceiling-side frame 2 and a floor-side frame 3. The ceiling-side frame 2 holds the ceiling-mounted air conditioner 21, the return air chamber 22, and the intake air port unit 26 internally, and is attached to the top of the floor-side frame 3. The floor-side frame 3 can house the supply air unit 4 and is fixed to the floor surface F with anchors 35 (the anchors 35 are embedded in the floor surface F and are therefore mostly invisible, but are shown in Figure 1 for ease of understanding). Both the ceiling-side frame 2 and the floor-side frame 3 are rectangular parallelepiped-shaped frames overall. Therefore, when transporting the rectangular parallelepiped ceiling-side frame 2 and floor-side frame 3 separately, they are less bulky than when they are integrated, making transportation easier.

[0022] The air conditioning module 1 is a displacement air conditioner that cools the air in the space to be air-conditioned S, which is drawn in from the intake port 27 of the intake unit 26, with the ceiling-mounted air conditioner 21, and blows out the low-temperature air from the air supply port 42 on the front of the supply unit 4 via the return air chamber 22 and ducts. For this reason, the intake port 27 is located at a relatively high position in the space to be air-conditioned S, and the air supply port 42 is located at a relatively low position in the space to be air-conditioned S. The intake unit 26 having the intake port 27 is held by the ceiling-side frame 2, and the air supply unit 4, which is installed near the floor surface F, can be housed inside the floor-side frame 3.

[0023] The ceiling-mounted air conditioner 21 is a fan coil unit that incorporates an electric fan for blowing air and a cooling coil. It cools the air drawn in from the intake port 27 of the intake port unit 26 and sends it to the return air chamber 22. A filter is located at the intake port 27. Therefore, airborne particles floating in the air-conditioned space S do not enter the ceiling-mounted air conditioner 21. The exterior of the ceiling-mounted air conditioner 21 is equipped with chilled water piping connected to the cooling coil, an electric valve, drain piping, power cables, and control wiring connected to the controller. Therefore, the ceiling-side frame structure 25 of the ceiling-side frame 2 not only holds the ceiling-mounted air conditioner 21, the return air chamber 22, and the intake port unit 26, but also protects these ancillary parts located on the exterior of the ceiling-mounted air conditioner 21 from the surroundings when the ceiling-side frame 2 is transported.

[0024] The ceiling-mounted air conditioner 21 can utilize commercially available ceiling-mounted air conditioners. Therefore, the ceiling-mounted air conditioner 21 can be procured relatively inexpensively. Such commercially available ceiling-mounted air conditioners are typically installed in the narrow space above the ceiling between the flooring material that makes up the floor surface of the upper floor or rooftop of a building and the decorative ceiling panels that make up the ceiling surface. Therefore, as shown in Figures 1 and 2, the ceiling-mounted air conditioner 21 basically has a horizontally elongated appearance, with its horizontal dimension being longer than its vertical dimension. Consequently, the ceiling-side frame structure 25 that houses the ceiling-mounted air conditioner 21 also has a horizontally elongated appearance, with its horizontal dimension being longer than its vertical dimension. Yes, they are.

[0025] As shown in Figures 1 and 2, the ceiling frame 2 connects a return air chamber 22 to an exhaust port on the side of the rectangular ceiling-mounted air conditioner 21 housing, and connects an intake port unit 26 to an intake port located on the side of the ceiling-mounted air conditioner 21 housing opposite the exhaust port. Therefore, the ceiling frame 2 positions the ceiling-mounted air conditioner 21 in the center of the ceiling frame structure 25, and the ceiling-mounted air conditioner 21 is sandwiched between the intake port unit 26 and the return air chamber 22. The connection between the ceiling-mounted air conditioner 21 and the intake port unit 26, and the connection between the return air chamber 22 and the ceiling-mounted air conditioner 21 are flexibly connected, allowing for some relative movement. That is, one opening that fits into the other opening is made slightly smaller, and the gap between the openings is filled with a sealing material such as a flexible sponge packing for airtightness, resulting in a flexible connection structure that allows for some relative movement. Therefore, when fixing the ceiling-mounted air conditioner 21, the intake unit 26, and the return air chamber 22 to the ceiling-side frame structure 25, even if there is some error in the relative positional relationship between the ceiling-mounted air conditioner 21, the intake unit 26, and the return air chamber 22, the flexible connection structure can absorb the error.

[0026] The ceiling-mounted air conditioner 21 is designed to be used suspended by suspension fittings such as suspension bolts installed in the building. Therefore, the ceiling-mounted air conditioner 21 is fixed to the ceiling frame structure 25 using the mounting parts of the suspension fittings provided on the exterior surface of the ceiling-mounted air conditioner 21. Since the ceiling-mounted air conditioner 21 has a built-in electric fan, vibration-damping rubber or the like is used at the mounting part to block the transmission of vibrations from the ceiling-mounted air conditioner 21 to the ceiling frame structure 25. For this reason, the ceiling-mounted air conditioner 21 needs to be able to move relative to the ceiling frame structure 25 to a certain extent. On the other hand, the intake unit 26 and the return air chamber 22 do not have a built-in drive unit such as an electric fan like the ceiling-mounted air conditioner 21, and therefore do not generate vibrations. For this reason, the intake unit 26 and the return air chamber 22 are fixed to the ceiling frame structure 25 without using vibration-damping rubber or other parts that block vibration transmission. Therefore, by providing a flexible connection structure for the ceiling-mounted air conditioner 21 to the intake unit 26 and the return air chamber 22, even if the ceiling-mounted air conditioner 21 moves due to vibrations from the electric fan or earthquakes, the connection between the ceiling-mounted air conditioner 21, the intake unit 26, and the return air chamber 22 will not be affected.

[0027] Incidentally, the ceiling-side frame 2, which integrates the ceiling-mounted air conditioner 21, the return air chamber 22, and the intake air unit 26, is naturally heavier than each of the individual components. Therefore, considering the transportation of the ceiling-side frame 2 and its attachment to the top of the floor-side frame 3, it is desirable to reduce the overall weight of the ceiling-side frame 2 as much as possible. For this reason, aluminum angle materials 23 are used in the ceiling-side frame structure 25 of the ceiling-side frame 2. For this reason, even in the parts where the angle materials 23 constituting the ceiling-side frame structure 25 are fastened together, rib plates 24 are fixed to the angle materials 23 with bolts, so that sufficient strength is achieved compared to welding the angle materials 23 together.

[0028] The floor-side frame structure 31, which constitutes the floor-side frame 3, is the same as the ceiling-side frame structure 25, and in the ceiling-side frame structure 25, aluminum angle members 33 are used. Therefore, even in the parts where the angle members 33 constituting the floor-side frame structure 31 are fastened together, rib plates 32 are fixed to the angle members 33 with bolts, so that sufficient strength is achieved compared to when the angle members 33 are welded together. In addition, since the load of the ceiling-side frame 2 is applied to the floor-side frame structure 31, brace members 34 are provided to further increase its strength.

[0029] The air supply unit 4 consists of a rectangular prism housing 41 in which the height is greater than the width and depth, and housing 4 The unit 1 comprises a panel forming the front, with multiple air inlets 42 formed at the openings, and a perforated plate 43 positioned to cover all of the air inlets 42. Low-temperature air supplied from the ceiling-mounted air conditioner 21 through a return air chamber 22 and connecting ducts flows into the air supply unit 4 and is blown out from the air inlets 42 toward the front of the air supply unit 4.

[0030] Each air intake vent 42 is fitted with multiple guide fins to impart a swirling component to the low-temperature air blown into the air-conditioned space S. The guide fins are fixed radially in a propeller-like shape around the central axis of each air intake vent 42, thereby imparting a swirling component to the air passing through the air intake vent 42. This swirling component is in opposite directions to adjacent air intake vents 42; for example, if a clockwise swirling component is imparted to a particular air intake vent 42, a counterclockwise swirling component will be imparted to the adjacent air intake vent 42. As a result, low-temperature air is blown out from the air intake vents 42 at a low speed toward the front of each air intake unit 4, flowing into the air-conditioned space S while drawing in surrounding air. This achieves draft-free displacement air conditioning while maintaining temperature stratification within the air-conditioned space S. Using such an air intake unit 4, the surrounding air is drawn in, so the coldness of the air blown out from the air intake vents 42 is prevented from being felt by people. Therefore, in this embodiment, compared to a system that performs displacement air conditioning with air blown out without adding a swirling component, countermeasures such as reheating or setting a lower limit on the blown-out temperature to prevent people in the air-conditioned space S from feeling cold at their feet are unnecessary.

[0031] Figure 3 illustrates the displacement air conditioning system using the air conditioning module 1. When the air conditioning module 1 is activated, air from the air intake unit 26 on the ceiling frame 2 is drawn in from within the air-conditioned space S, cooled by the ceiling-mounted air conditioner 21, and blown out as low-temperature air from the supply unit 4. The low-temperature air blown out from the supply unit 4 flows slowly horizontally from the supply unit 4, drawing in surrounding air. The low-temperature air that flows into the air-conditioned space S gradually warms up due to the body heat of people in the space S and heat generated from machinery, and slowly rises due to convection. The rising air is then drawn in again from the air intake unit 26 on the ceiling frame 2.

[0032] In light of the mechanism of this displacement air conditioning system, it is preferable that the intake port 27 of the intake unit 26 be positioned at a height of approximately 3000 mm from the floor surface F. If the intake port 27 is positioned higher than this, the amount of heat to be processed by the air conditioning module 1 will become excessive, increasing the running costs of the air conditioning module 1. Conversely, if the intake port 27 is positioned lower than this, there is a possibility that people in the air-conditioned space S may feel the heat from above the air-conditioned space S.

[0033] Furthermore, considering the passage of people near the air conditioning module 1, it is preferable to set the height of the floor-side frame 3 so that the ceiling-side frame 2 is at a height that does not touch people's heads (for example, 2.1m or more). If the ceiling-side frame 2 is positioned at such a height, people can pass under the ceiling-side frame 2 without difficulty.

[0034] As mentioned above, the air conditioning module 1 is attached to the upper part of the floor-side frame 3 such that the ceiling-side frame 2 protrudes toward the front of the floor-side frame 3 at the top of the floor-side frame 3. This allows the floor-side frame 3 to be erected on the floor surface F so as to follow the wall surface W of the air-conditioned space S. This prevents the air conditioning module 1 from becoming a physical obstacle in the air-conditioned space S. For this reason, the floor-side frame 3 is provided with an angle member 33A that extends diagonally upward from the front of the floor-side frame structure 31 to support the ceiling-side frame 2 which protrudes toward the front of the floor-side frame 3 at the top of the floor-side frame 3. In addition, to mitigate the bending load applied to the fastening portion between the upper part of the floor-side frame structure 31 and the ceiling-side frame structure 25, the center of gravity of the ceiling-side frame 2 is positioned relative to the floor-side frame 3 Care has been taken to ensure that it approaches directly above it.

[0035] In other words, the ceiling-mounted air conditioner 21 is heavier than the intake unit 26 and return air chamber 22 because it has a built-in cooling coil and electric fan. Therefore, the center of gravity of the ceiling frame 2 largely depends on the position of the ceiling-mounted air conditioner 21 within the ceiling frame 2. Accordingly, in the air conditioning module 1 of this embodiment, the ceiling frame 2 holds the ceiling-mounted air conditioner 21 in a position where its intake port faces directly to the side relative to the front direction, which is the direction of discharge of the supply air unit 4. The intake unit 26 and return air chamber 22, which are arranged to sandwich the ceiling-mounted air conditioner 21, are also arranged in order along the side relative to the front direction of the air conditioning module 1. Therefore, it is possible to position the ceiling-mounted air conditioner 21 within the ceiling frame 2 closer to the back side (wall W side) of the air conditioning module 1. As a result, for example, compared to a configuration in which the air intake unit 26, the ceiling-mounted air conditioner 21, and the return air chamber 22 are arranged in order from the front to the back of the air conditioning module 1, that is, a configuration in which the air intake unit 26's air intake 27 faces the front of the air conditioning module 1 and the ceiling-mounted air conditioner 21 is positioned closer to the front of the air conditioning module 1 than the return air chamber 22, the center of gravity of the ceiling-side frame 2 can be brought closer to directly above the floor-side frame 3. Therefore, it becomes easier to ensure the structural strength of the floor-side frame structure 31.

[0036] <Installation method for air conditioning module 1> The air conditioning module 1 of the above embodiment can be installed in a building at a construction site in the following manner. Figure 4 shows the floor-side frame 3. Figure 5 shows the ceiling-side frame 2. The air conditioning module 1 of the above embodiment can be manufactured by transporting the ceiling-side frame 2 and floor-side frame 3 separately at a location other than the construction site (for example, a factory), and then assembled at the construction site.

[0037] In other words, as shown in Figure 4, the floor frame 3 is prepared in a factory or similar facility by constructing the floor frame structure 31 with rib plates 32, angle members 33, and brace members 34. The angle member 33A is attached to the floor frame structure 31 via the rib plate 32A in a rotatable manner, and it is preferable to temporarily fix the angle member 33A to the floor frame structure 31 so that it does not move during transport. When installing multiple air conditioning modules 1 at a construction site, multiple floor frames 3 are manufactured at a factory or similar facility and transported to the construction site by vehicle or the like.

[0038] Furthermore, as shown in Figure 5, the ceiling frame structure 25 is constructed using angle material 23 and rib plate 24 for the ceiling frame 2, and the ceiling-mounted air conditioner 21, return air chamber 22, and intake unit 26 are attached to the ceiling frame structure 25. When multiple air conditioning modules 1 are to be installed at the construction site, multiple ceiling frames 2 are manufactured in a factory or similar facility and transported to the construction site by vehicle or similar means.

[0039] Figure 6 is the first diagram showing the installation method of the air conditioning module 1. When the ceiling frame 2 and floor frame 3 are transported to the construction site, first, the floor frame 3 is positioned with its back side against the wall W, and the lower part 36 of the floor frame 3 is fixed to the floor F with anchors 35. The air supply unit 4, which was transported separately from the floor frame 3, is then positioned to fit into the storage compartment 37 for the air supply unit 4 formed in the floor frame 3, and the air supply unit 4 is fixed to the floor F and the floor frame 3. The air supply unit 4 may be fixed directly to the floor F, or it may be fixed indirectly through some kind of member.

[0040] Furthermore, the air supply unit 4 is positioned at an appropriate depth within the storage compartment 37 so that the airflow of the air blown out from the air intake port 42 of the air supply unit 4 is not affected by the angle material 33 of the floor-side frame structure 31. The air blown out from the air intake port 42 comes from the front direction of the air intake port 42. Because the air flows in a slightly spreading manner, it is preferable that the angle members 33 of the frame structure 31 be positioned slightly away from the path of the air (for example, outside the range of an opening angle of about 16 degrees with respect to the front direction of the air intake 42).

[0041] Figure 7 is a second diagram showing the installation method of the air conditioning module 1. Once the floor frame 3 is installed, the ceiling frame 2 is then fixed to the upper part 38 of the floor frame 3 with bolts and nuts. An angle material 33A is fastened to the front side of the ceiling frame 2, so that the front side of the ceiling frame 2 is supported by the angle material 33A. The return air chamber 22 and the supply air unit 4 are then connected with a flexible duct or the like. A controller and temperature sensor for controlling the ceiling-mounted air conditioner 21 are placed in appropriate locations, and connections are made for chilled water piping, drain piping, etc. When the temperature sensor is attached to the floor frame 3, it is preferable to attach it to a location where it is not directly hit by the air blown out from the air intake port 42 of the supply air unit 4. In displacement air conditioning, a suitable location for the temperature sensor is a place where the detected temperature is equivalent to the temperature felt by a person, that is, a height of about 1.1m from the floor surface F.

[0042] With the above steps completed, the installation of the air conditioning module 1 in the air-conditioned space S at the construction site is finished. If you want to implement displacement air conditioning with a relatively inexpensive ceiling-mounted air conditioner, you can complete the installation of the displacement air supply unit 4, which needs to be installed near the floor surface F, and the ceiling-mounted air conditioner 21, which is designed to be suspended from the ceiling, with a relatively simple operation of fixing the ceiling-side frame 2 to the upper part 38 of the floor-side frame 3. Therefore, compared to a configuration in which the ceiling-mounted air conditioner 21 is suspended from the ceiling and the ceiling-mounted air conditioner 21 and the supply unit 4 installed on the floor surface F are connected by ducts, the on-site work can be greatly simplified.

[0043] <Variation> The air conditioning module 1 of the above embodiment may be modified as follows, for example.

[0044] Figure 8 is a view of an air conditioning module according to a modified example, seen from an oblique angle above. The air conditioning module 1 may be configured, for example, as shown in Figure 8, with multiple shelves 39 provided on the floor-side frame 3. The part of the floor-side frame 3 other than where the air supply unit 4 is placed is an empty space because it is a floor-side frame structure 31 made of angle material 33. Therefore, by providing shelves 39 on the floor-side frame structure 31, this empty space can be effectively utilized as storage space.

[0045] <Other variations> Furthermore, in the above embodiment, the air intake port 27 was configured to open to the right toward the front of the air conditioning module 1. However, by reversing the relative positions of the air intake port unit 26, the ceiling-mounted air conditioner 21, the return air chamber 22, and the supply air unit 4, the air intake port 27 may be configured to open to the left toward the front of the air conditioning module 1.

[0046] Furthermore, in the above embodiment, the ceiling frame 2 was positioned above the floor frame 3 and protruding towards the front of the floor frame 3. However, the ceiling frame 2 may be attached to the floor frame 3 in such a manner that, for example, the center of gravity of the ceiling frame 2 is located directly above the floor frame 3. This would reduce the effective space of the floor surface F, but it would stabilize the balance of the center of gravity of the entire air conditioning module 1.

[0047] Furthermore, the air conditioning module 1 may be modified as appropriate. For example, the air conditioning module 1 may be such that a decorative panel or the like is attached to cover the ceiling-side frame structure 25 and the floor-side frame structure 31. Also, the air conditioning module 1 may be fixed not only to the floor surface F with anchors 35, but also to the wall surface W with anchors. In addition, the air conditioning module 1 is not a displacement air conditioning system. Air supply portIt may also be a system that forcefully blows air out to circulate the air in the room. Furthermore, the air conditioning module 1 may be formed from a single integrated frame rather than having separate ceiling-side frame 2 and floor-side frame 3. If the frame is an integrated structure, the amount of assembly work at the site will be reduced, thus reducing the amount of work required at the site. [Explanation of symbols]
