Description

The present invention relates to an air conditioning module and a method for installing an air conditioning module.

In recent years, various air conditioning systems have been proposed (for example, see Patent Documents 1 and 2).

Patent No. 5780892 Patent No. 4421347

Examples of types of air conditioning equipment installed in buildings include package coolers, which have a refrigeration cycle inside the machine consisting of a compressor, condenser, etc., and cool water produced by the refrigerator that passes through coils inside the machine. Examples include fan coil units and various other items. In addition, the types of airflow in the air-conditioned space include those that forcefully circulate indoor air by blowing air out from the air supply vents, and displacement air conditioning that blows out low-temperature air at a low speed to maintain indoor temperature stratification. Examples include.

Many commercially available air conditioners are configured to blow air out from air supply ports provided at appropriate locations in the housing. Therefore, for example, if you want to implement displacement air conditioning with a ceiling-mounted air conditioner that is widely available on the market and available at a relatively low price, you may need to install an air supply unit for displacement air conditioning that needs to be placed near the floor. It was necessary to connect the ceiling-mounted air conditioner, which was prepared separately and placed near the ceiling, with the air supply unit, which was placed near the floor, using a duct, making it difficult to reduce on-site work.

The present invention has been made in view of the above problems, and provides an air conditioning module and a method for installing the air conditioning module that facilitate the installation of an air supply unit placed near the floor and a ceiling-mounted air conditioner connected to the air supply unit. The task is to do so.

In order to solve the above problems, in the present invention, a ceiling frame that holds a ceiling-mounted air conditioner inside is attached to the upper part of a floor frame in which an air supply unit placed near the floor can be placed.

Specifically, the present invention relates to an air conditioning module that is installed on the floor of an air-conditioned space, and which is connected to a floor-side frame that is arranged near the floor and can house an air supply unit therein, and which is connected to the air supply unit. A ceiling-side frame that holds a ceiling-suspended air conditioner inside and can be attached to the upper part of the floor-side frame is provided.

Here, the air supply unit arranged near the floor is a concept that includes not only a form directly installed on the floor but also a form installed indirectly on the floor. Furthermore, the term "module" is not limited to a state in which a floor frame and a ceiling frame are integrated, but is a concept that includes a state in which the floor frame and ceiling frame are separate.

With the above air conditioning module, you can simply attach the ceiling frame to the top of the floor frame installed on the floor, and it is designed to be suspended from the ceiling above the air supply unit installed near the floor. Ceiling-mounted air conditioners can be fixed. Therefore, for example, even if you want to achieve displacement air conditioning with a ceiling-hanging air conditioner that is available at a relatively low cost, it is a relatively easy task to fix the ceiling frame to the top of the floor frame. This completes the installation of an air supply unit for displacement air conditioning, which needs to be installed near the floor, and a ceiling-mounted air conditioner, which is designed to be suspended from the ceiling. Therefore, it can be said that with the above air conditioning module, on-site work can be extremely simplified.

Note that the ceiling-side frame may further hold an inlet unit connected to the ceiling-mounted air conditioner inside. According to this, installation of both the ceiling-mounted air conditioner and the air intake unit can be completed with a relatively simple task of fixing the ceiling-side frame to the upper part of the floor-side frame.

In addition, the ceiling-mounted air conditioner has an overall rectangular external shape, and has an inlet on the side of the rectangular parallelepiped to which the inlet unit is connected. The ceiling-mounted air conditioner may be held in a position facing right sideways with respect to the front direction. According to this, it becomes easy to bring the center of gravity of the ceiling frame attached to the upper part of the floor frame closer to directly above the floor frame.

In addition, the air supply unit is placed on the floor frame in the opposite direction to the direction in which the air intake of the ceiling-mounted air conditioner is facing. It may have a plate. According to this, the empty space of the floor frame can be effectively utilized.

In addition, the floor frame is a frame that is installed vertically so that its back side is along the wall surface of the air-conditioned space, and the ceiling frame is a frame that is installed at the top of the floor frame so that it protrudes toward the front side of the floor frame. It may be attached to the top of the side frame. According to this, since the floor frame can be installed in a state close to the wall surface, it is possible to prevent the air conditioning module from becoming a physical obstacle.

Furthermore, the air supply unit may be a displacement air conditioning unit that has a plurality of circular air supply ports in the front with guide fins in the mouth that give a swirling component to the low-temperature air supplied from the ceiling-mounted air conditioner. good. According to this, it is possible to realize displacement air conditioning without a draft feeling while maintaining temperature stratification in the air-conditioned space.

Moreover, the present invention can also be viewed from the aspect of a method. For example, the present invention provides an air conditioning module installation method for installing any of the air conditioning modules described above in a building at a construction site, comprising an assembly step of assembling a floor frame and a ceiling frame, respectively, outside the construction site; Even if the method includes a transportation process of transporting the floor frame and the ceiling frame to a construction site, and an installation process of fixing the floor frame to the floor surface and then attaching the ceiling frame to the top of the floor frame, good.

With the air conditioning module and the air conditioning module installation method described above, it becomes easy to install the air supply unit disposed near the floor surface and the ceiling-mounted air conditioner connected to the air supply unit.

Embodiments of the present invention will be described below. The embodiment shown below is an example of the embodiment of the present invention, and the technical scope of the present invention is not limited to the following aspects.

FIG. 1 is a diagram of an air conditioning module according to an embodiment viewed diagonally from above. Moreover, FIG. 2 is a diagram of the air conditioning module according to the embodiment viewed diagonally from below. In FIG. 1, the air conditioning module 1 is shown standing upright from the floor F so that its back side is along the wall W of the space S to be air conditioned. Moreover, in FIG. 2, the floor surface F is shown in a transparent state from below the floor surface F on which the air conditioning module 1 is installed.

As shown in FIGS. 1 and 2, the air conditioning module 1 is an air conditioning module installed on the floor F of the air-conditioned space S, and includes a ceiling frame 2 and a floor frame 3. The ceiling-side frame 2 holds a ceiling-suspended air conditioner 21, a return air chamber 22, and an intake port unit 26 inside, and is attached to the upper part of the floor-side frame 3. The floor frame 3 can house the air supply unit 4, and is fixed to the floor F with anchors 35 (the anchors 35 are mostly invisible since they are embedded in the floor F, but the figure 1 is illustrated for ease of understanding). Both the ceiling side frame 2 and the floor side frame 3 are rectangular parallelepiped-shaped frames as a whole. Therefore, when the rectangular parallelepiped-shaped ceiling frame 2 and floor frame 3 are transported separately, they are easier to transport because they are less bulky than when both are integrated.

The air conditioning module 1 cools the air in the air-conditioned space S drawn in from the intake port 27 of the intake port unit 26 using the ceiling-mounted air conditioner 21, and supplies the air in front of the air supply unit 4 via the return air chamber 22 and duct. This is a displacement air conditioner that blows out low-temperature air from an air port 42. For this reason, the intake port having the intake port 27 is arranged such that the intake port 27 is arranged at a relatively high location in the air-conditioned space S, and the air supply port 42 is arranged at a relatively low location in the air-conditioned space S. The unit 26 is held by the ceiling frame 2, and the air supply unit 4 installed near the floor surface F can be placed inside the floor frame 3.

The ceiling-mounted air conditioner 21 is a fan coil unit incorporating an electric fan for blowing air and a cooling coil, and cools the air sucked in from the intake port 27 of the intake port unit 26 and sends it to the return air chamber 22. A filter is arranged in the intake port 27. Therefore, floating objects floating within the air-conditioned space S do not enter the ceiling-mounted air conditioner 21. The exterior of the ceiling-mounted air conditioner 21 is provided with cold water piping connected to the cooling coil, electric valves, drain piping, power cables, control wiring connected to the controller, and the like. Therefore, the ceiling-side frame structure 25 of the ceiling-side frame 2 plays the role of holding the ceiling-suspended air conditioner 21 , the return air chamber 22 , and the intake port unit 26 , and is also provided on the exterior of the ceiling-suspended air conditioner 21 . It also serves to protect these incidental parts from the surroundings when the ceiling frame 2 is being transported.

As the ceiling-suspended air conditioner 21, a commercially available ceiling-suspended air conditioner can be used. Therefore, the ceiling-mounted air conditioner 21 can be procured at relatively low cost. Such commercially available ceiling-mounted air conditioners are usually installed in the narrow attic space between the flooring that makes up the upper floor or rooftop of a building and the decorative ceiling panel that makes up the ceiling. will be installed. Therefore, as shown in FIGS. 1 and 2, the ceiling-mounted air conditioner 21 basically has an oblong external shape in which the horizontal dimension is longer than the vertical dimension. Therefore, the ceiling-side frame structure 25 in which the ceiling-suspended air conditioner 21 is installed also has a laterally elongated external shape in which the horizontal dimension is longer than the vertical dimension.

As shown in FIGS. 1 and 2, the ceiling-side frame 2 connects the return air chamber 22 to the exhaust port on the side surface of the casing of the rectangular parallelepiped ceiling-mounted air conditioner 21. An intake port unit 26 is connected to the intake port located on the opposite side of the exhaust port. Therefore, the ceiling frame 2 is configured such that the ceiling air conditioner 21 is placed in the center of the ceiling frame structure 25 and the ceiling air conditioner 21 is sandwiched between the air intake unit 26 and the return air chamber 22. There is. The connecting portion between the ceiling-mounted air conditioner 21 and the air intake unit 26, and the connection portion between the return air chamber 22 and the ceiling-mounted air conditioner 21 are connected flexibly, allowing for some relative movement. There is. In other words, the opening that is fitted into one opening is made slightly smaller, and the gap between the openings is filled with a sealing material such as flexible sponge packing to prevent some relative movement. It has a flexible connection structure that allows for Therefore, when fixing the ceiling-mounted air conditioner 21, the intake port unit 26, and the return air chamber 22 to the ceiling-side frame structure 25, the relative positions of the ceiling-mounted air conditioner 21, the intake port unit 26, and the return air chamber 22 are determined. Even if some error occurs in the relationship, the error can be absorbed by the flexible connection structure.

The ceiling-mounted air conditioner 21 is designed to be used in a suspended state using a hanging metal fitting such as a hanging bolt provided on a building. Therefore, the ceiling-suspended air conditioner 21 is fixed to the ceiling-side frame structure 25 using the mounting portion of the hanging metal fitting provided on the exterior surface of the ceiling-suspended air conditioner 21. Since the ceiling-mounted air conditioner 21 has a built-in electric fan, anti-vibration rubber or the like is used in the mounting part to block the transmission of vibration from the ceiling-mounted air conditioner 21 to the ceiling frame structure 25. It turns out. Therefore, the ceiling-mounted air conditioner 21 needs to be allowed to move relative to the ceiling frame structure 25 to some extent. On the other hand, the intake port unit 26 and the return air chamber 22 do not have a built-in drive unit such as an electric fan, unlike the ceiling-mounted air conditioner 21, and therefore basically do not generate vibrations. Therefore, the intake port unit 26 and the return air chamber 22 are fixed to the ceiling-side frame structure 25 without using parts such as anti-vibration rubber that block vibration transmission. Therefore, by making the ceiling-mounted air conditioner 21 have a flexible connection structure to the intake port unit 26 and the return air chamber 22, even if the ceiling-mounted air conditioner 21 moves due to electric fan vibrations, earthquakes, etc., the ceiling-mounted air conditioner 21 21, the intake port unit 26, and the return air chamber 22, so as not to interfere with the connection portion.

By the way, the ceiling frame 2 in which the ceiling-mounted air conditioner 21, the return air chamber 22, and the intake port unit 26 are integrated has the following effects when compared with the ceiling-mounted air conditioner 21, the return air chamber 22, and the intake port unit 26 as individual units. Of course it's heavy. Therefore, in consideration of transportation of the ceiling frame 2 and attachment to the upper part of the floor frame 3, it is desirable to reduce the weight of the entire ceiling frame 2 as much as possible. Therefore, in the ceiling side frame structure 25 of the ceiling side frame 2, an angle member 23 made of aluminum is used. Therefore, even in the part where the angle members 23 constituting the ceiling side frame structure 25 are fastened together, by fixing the rib plate 24 to the angle members 23 with bolts, the angle members 23 can be welded together. It allows the strength to be demonstrated.

The floor frame structure 31 constituting the floor frame 3 is also similar to the ceiling frame structure 25, and the ceiling frame structure 25 uses an angle material 33 made of aluminum. Therefore, even in the part where the angle members 33 constituting the floor side frame structure 31 are fastened together, by fixing the rib plate 32 to the angle members 33 with bolts, the angle members 33 can be welded together. It allows the strength to be demonstrated. Furthermore, since the load of the ceiling frame 2 is applied to the floor frame structure 31, a brace material 34 is provided to further increase the strength.

The air supply unit 4 includes a rectangular parallelepiped casing 41 whose height is larger than its width and depth;
A plurality of air supply ports 42 are formed in a panel forming the front surface of the air supply device 1, and a perforated plate 43 is provided so as to cover the entirety of the plurality of air supply ports 42. Low-temperature air supplied from the ceiling-mounted air conditioner 21 through the return air chamber 22, connection duct, etc. flows into the air supply unit 4, and is blown out from the air supply port 42 toward the front of the air supply unit 4. It has become.

A plurality of guide fins are fixed to each air supply port 42, respectively, for giving a swirling component to the low-temperature air blown into the air-conditioned space S. Guide fins are radially fixed around the central axis of each air supply port 42 in a propeller-like form, thereby imparting a swirling component to the air passing through the air supply port 42. This swirl component is in a direction opposite to each other between adjacent air supply ports 42. For example, when a clockwise swirl component is given to a specific air supply port 42, the direction of the swirl component in the adjacent air supply port 42 is counterclockwise. A rotational component of the direction is given. As a result, low-temperature air is blown out at low speed from the air supply ports 42 toward the front of each air supply unit 4, and flows into the air-conditioned space S while attracting surrounding air. Then, displacement air conditioning without a draft feeling is realized while maintaining temperature stratification within the air-conditioned space S. If such an air supply unit 4 is used, the air around the air supply port 42 is attracted, so that the person can be prevented from feeling cold due to the air blown out from the air supply port 42. Therefore, in this embodiment, compared to a system in which displacement air conditioning is performed using blown air without adding a swirling component, it is possible to prevent people in the air-conditioned space S from feeling cold under their feet. Countermeasures such as reheating or setting a lower limit for the blowout temperature are not required.

FIG. 3 is a diagram illustrating an image of replacement air conditioning by the air conditioning module 1. When the air conditioning module 1 is activated, the air in the air-conditioned space S sucked in from the air intake unit 26 of the ceiling frame 2 is cooled in the ceiling-mounted air conditioner 21, and is blown out from the air supply unit 4 as low-temperature air. The low temperature air blown out from the air supply unit 4 flows laterally from the air supply unit 4 at low speed while attracting surrounding air. The low-temperature air flowing into the air-conditioned space S gradually rises in temperature due to the body temperature of people in the air-conditioned space S, heat generated from machinery, etc., and slowly rises due to convection. Then, the rising air is sucked in again from the air intake unit 26 of the ceiling side frame 2.

In view of such a mechanism of displacement air conditioning, it is preferable that the intake port 27 of the intake port unit 26 be arranged at a height of about 3000 mm from the floor surface F, for example. If the intake port 27 is placed higher than this, the amount of heat of the air conditioning processed in the air conditioning module 1 will be excessive, and the running cost of the air conditioning module 1 will increase. Moreover, if the air intake port 27 is arranged at a lower location than this, there is a possibility that the people in the air-conditioned space S will feel the hot air above the air-conditioned space S.

In addition, considering the number of people passing around the air conditioning module 1, the height of the floor frame 3 is set so that the ceiling frame 2 does not touch people's heads (for example, 2.1 m or more). It is preferable. If the ceiling side frame 2 is arranged at such a height, people can pass under the ceiling side frame 2 without any inconvenience.

By the way, as mentioned above, the air conditioning module 1 is attached to the upper part of the floor frame 3 with the ceiling frame 2 protruding toward the front side of the floor frame 3 at the upper part of the floor frame 3. This allows the floor frame 3 to be erected on the floor F along the wall W of the air-conditioned space S. This suppresses the air conditioning module 1 from becoming a physical obstacle in the air-conditioned space S. Therefore, the angle material 33A for supporting the ceiling frame 2, which protrudes toward the front side of the floor frame 3 at the upper part of the floor frame 3, is attached to the floor frame 3. It is provided so as to extend diagonally upward from the structure 31 on the front side of the floor frame structure 31. In addition, the center of gravity of the ceiling frame 2 is set so that the center of gravity of the ceiling frame 2
Care has been taken to bring it close to directly above the

That is, the ceiling-mounted air conditioner 21 has a built-in cooling coil and an electric fan, so it is heavier than the air intake unit 26 and the return air chamber 22. 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. Therefore, in the air conditioning module 1 of the present embodiment, the ceiling-side frame 2 holds the ceiling-suspended air conditioner 21 in an attitude in which the suction port of the ceiling-suspended air conditioner 21 faces right sideways with respect to the front direction, which is the blowing direction of the air supply unit 4. are doing. The air intake unit 26 and the return air chamber 22, which are arranged to sandwich the ceiling-mounted air conditioner 21, are also arranged in order in the lateral direction with respect to the front direction of the air conditioning module 1. Therefore, the ceiling-mounted air conditioner 21 can be placed in the ceiling frame 2 at a position close to the back side (wall surface W side) of the air conditioning module 1. As a result, for example, the air intake port unit 26, the ceiling-mounted air conditioner 21, and the return air chamber 22 are arranged in order from the front side to the back side of the air conditioning module 1, that is, the air intake port 27 of the air intake port unit 26 is Compared to a configuration in which the ceiling-mounted air conditioner 21 is placed closer to the front of the air conditioning module 1 than the return air chamber 22, the center of gravity of the ceiling frame 2 is moved directly above the floor frame 3. It can be brought closer. Therefore, it becomes possible to ensure the structural strength of the floor frame structure 31 more easily.

<How to install air conditioning module 1>
The air conditioning module 1 of the above embodiment can be installed in a building at a construction site by the following method. FIG. 4 is a diagram showing the floor frame 3. As shown in FIG. Moreover, FIG. 5 is a diagram showing the ceiling side frame 2. As shown in FIG. The air conditioning module 1 of the above embodiment can, for example, manufacture the ceiling frame 2 and the floor frame 3 separately at a location other than the construction site (for example, a factory), transport them, and then assemble them at the construction site. It is.

That is, as shown in FIG. 4, the floor frame structure 31 of the floor frame 3 is made up of rib plates 32, angle members 33, and brace members 34 in a factory or the like. The angle material 33A is rotatably attached to the floor frame structure 31 via the rib plate 32A, and is temporarily fixed to the floor frame structure 31 to prevent the angle material 33A from moving during transportation. It is preferable to leave it there. When installing multiple air conditioning modules 1 at a construction site, multiple floor frames 3 are manufactured in a factory or the like and transported to the construction site by vehicle or the like.

Further, as shown in FIG. 5, regarding the ceiling side frame 2, a ceiling side frame structure 25 is constituted by an angle material 23 and a rib plate 24, and a ceiling side air conditioner 21, a return air chamber 22, an air intake unit 26, etc. is attached to the ceiling side frame structure 25. When a plurality of air conditioning modules 1 are installed at a construction site, a plurality of ceiling frames 2 are manufactured in a factory or the like and transported to the construction site by vehicle or the like.

FIG. 6 is a first diagram showing the installation method of the air conditioning module 1. When the ceiling frame 2 and the floor frame 3 are transported to the construction site, the floor frame 3 is first placed with its back side along the wall surface W, and the lower part 36 of the floor frame 3 is aligned with the floor surface F. Fix it with anchor 35. In addition, the air supply unit 4 that has been transported separately from the floor frame 3 is arranged so as to be housed in the storage section 37 for the air supply unit 4 formed in the floor frame 3, and the air supply unit 4 is It is fixed to the floor F or the floor frame 3. The air supply unit 4 may be directly fixed to the floor surface F, or may be fixed indirectly via some kind of member.

Note that the air supply unit 4 is installed at an appropriate depth within the storage section 37 so that the airflow blown out from the air supply port 42 of the air supply unit 4 is not affected by the angle members 33 of the floor frame structure 31, etc. Place it at the position. Since the air blowing out from the air supply port 42 flows in a form that spreads slightly from the front direction of the air supply port 42, the angle member 33 of the frame structure 31 is located at a position slightly away from the path of the air (for example, It is preferable that the opening angle is outside the range of about 16 degrees with respect to the front direction of the air port 42.

FIG. 7 is a second diagram showing the installation method of the air conditioning module 1. When the installation of the floor frame 3 is completed, the ceiling frame 2 is then fixed to the upper part 38 of the floor frame 3 with bolts and nuts. Further, the angle member 33A is fastened to the front side of the ceiling-side frame 2, and the front side of the ceiling-side frame 2 is supported by the angle member 33A. Then, the return air chamber 22 and the air supply unit 4 are connected by a flexible duct or the like. Further, a controller and a temperature sensor for controlling the ceiling-mounted air conditioner 21 are arranged at appropriate locations, and cold water piping, drain piping, etc. are connected. When the temperature sensor is attached to the floor frame 3, it is preferable to attach it to a location where the air blown out from the air supply port 42 of the air supply unit 4 does not come into direct contact with the temperature sensor. A suitable location for installing the temperature sensor in displacement air conditioning is a location where the detected temperature is equivalent to the sensible temperature of a person, that is, a height of about 1.1 m from the floor surface F.

With the above steps, the work of installing the air conditioning module 1 in the air conditioning target space S, which is the construction site, is completed. With the air conditioning module 1, if you want to achieve displacement air conditioning with a ceiling-hanging type air conditioner that is available at a relatively low cost, you can use the relatively simple method of fixing the ceiling frame 2 to the upper part 38 of the floor frame 3. This work completes the installation of the replacement air conditioning air supply unit 4, which needs to be installed near the floor F, and the ceiling-mounted air conditioner 21, which is designed to be suspended from the ceiling. Therefore, compared to a configuration in which the ceiling-suspended air conditioner 21 is suspended from the ceiling and the ceiling-suspended air conditioner 21 suspended from the ceiling is connected to the air supply unit 4 installed on the floor surface F using a duct, on-site work is greatly simplified. It can be simplified.

<Modified example>
Note that the air conditioning module 1 of the above embodiment may be modified as follows, for example.

FIG. 8 is a diagram of an air conditioning module according to a modified example viewed diagonally from above. For example, as shown in FIG. 8, the air conditioning module 1 may have a configuration in which a plurality of shelf boards 39 are provided on the floor frame 3. The portion of the floor frame 3 other than the location where the air supply unit 4 is disposed is an empty space because the floor frame structure 31 is made of angle material 33. Therefore, by providing the shelf board 39 on the floor-side frame structure 31, it becomes possible to effectively utilize such an empty space as a storage space.

<Other variations>
Further, in the above embodiment, the intake port 27 opens rightward toward the front of the air conditioning module 1, but the intake port unit 26, the ceiling-mounted air conditioner 21, the return air chamber 22, the air supply unit By reversing the positional relationship of all the air conditioners 4 from left to right, the air intake port 27 may open leftward toward the front of the air conditioning module 1.

Further, in the above embodiment, the ceiling side frame 2 is configured to protrude toward the front side of the floor side frame 3 above the floor side frame 3, but the ceiling side frame 2 is may be attached to the floor frame 3 in such a manner that it is located directly above the floor frame 3. According to this, although the floor frame 3 reduces the effective space on the floor surface F, the balance of the center of gravity of the entire air conditioning module 1 is stabilized.

In addition, the air conditioning module 1 may be modified as appropriate. The air conditioning module 1 may be configured such that, for example, a decorative board or the like is attached to cover the ceiling frame structure 25 and the floor frame structure 31. Moreover, 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. Furthermore, the air conditioning module 1 may be configured to forcibly circulate indoor air by forcefully blowing out air from an intake port instead of using displacement air conditioning. Further, in the air conditioning module 1, the ceiling side frame 2 and the floor side frame 3 may be formed as an integral frame instead of separate structures. If the frame is a one-piece structure, there will be less assembly work on-site, so the number of man-hours on-site work can be reduced.
