In the "underfloor ventilation structure for a building" described in Patent Document 1, since an air conditioner arranged in the attic space and a plurality of air outlets provided on the ceiling of the living part on each floor are connected by a duct, The design and construction of ducts that are installed across floors is very complicated. Also, since it is very difficult (and practically impossible) to clean the inside of the duct after construction, if a situation that requires the cleaning of the inside of the duct arises, we will respond by replacing the duct. It is the actual situation. For this reason, the duct replacement work requires a large amount of labor, time, and materials, and maintenance is poor.

Since the “air conditioning system” described in Patent Document 2 does not have a ventilation function, it cannot support 24-hour ventilation.

Then, the subject which this invention tends to solve is providing an air conditioning system which has an air-conditioning function and a ventilation function, is easy to install, and requires no duct maintenance.

A first entire building air conditioning system according to the present invention includes an air conditioner, a ventilation device, and an outlet that blows out conditioned air supplied from the air conditioner to an air conditioning target area in a building,
Arranging the air conditioner in the space behind the ceiling or the space behind the hut in the building,
At least one of the space above the ceiling or the space behind the hut is an air supply path for guiding conditioned air supplied from the air conditioner to the air outlet,
The outside air sucked by the ventilation device is supplied to the air conditioner.

With such a configuration, the provision of the air conditioner and the ventilation device allows the air conditioning function and the ventilation function to be exhibited. Further, since the duct construction between the air conditioner and the air outlet is unnecessary, the man-hours are simplified, the construction is easy, and since the air supply duct itself can be eliminated, the maintenance of the duct is also unnecessary. is there.

Furthermore, by supplying the outside air sucked in by the ventilation device to the air conditioner, it is possible to use both the air conditioning system and return air system routes, and it is possible to reliably obtain the required ventilation action and improve ventilation efficiency. To do. When the attic space is used as an air supply path (ductless space), conditioned air flows into the attic, which improves the attic environment and reduces the load on the air conditioner and the ventilation system.

A second entire building air conditioning system according to the present invention includes an air conditioner, a ventilation device, and an outlet that blows out conditioned air supplied from the air conditioner to an air conditioning target area in the building,
Arranging the air conditioner in the space behind the ceiling or the space behind the hut in the building,
At least one of the space above the ceiling and the space behind the hut is a return air path that sucks in air from a return air inlet provided in the building and leads the air conditioner.

With such a configuration, the provision of the air conditioner and the ventilation device allows the air conditioning function and the ventilation function to be exhibited. In addition, since the duct construction between the air conditioner and the suction port is not required, the man-hours are simplified, the construction is easy, and the return air duct itself can be eliminated, so maintenance of the duct is also unnecessary. is there.

Furthermore, by supplying the outside air sucked in by the ventilation device to the air conditioner, it is possible to use both the air conditioning system and return air system routes, and it is possible to reliably obtain the required ventilation action and improve ventilation efficiency. To do. When the attic space is used as a return air path (ductless space), the air in the indoor environment flows into the attic, which improves the attic environment and reduces the load on the air conditioner and ventilation system. If conditioned air is supplied from the air conditioner to the room via the duct, heat loss can be reduced.

In the entire building air conditioning system, the building is a two-story building, and the space above the ceiling between the first floor and the second floor in the building is the air supply path or the return air path, and the inside of the air supply path or The air conditioner may be arranged in the return air path.

In the entire building air conditioning system, the air conditioner may be a wall-mounted air conditioner.

With such a configuration, the wall-mounted air conditioner is relatively small, so that the installation work becomes easy. If a room air conditioner, which is a general-purpose product, is used as the wall-mounted air conditioner, replacement work at the time of renewal is easy, and the latest model high-performance room air conditioner can be selected each time.

In the entire building air conditioning system, the suction port for returning air that introduces the air in the building into the air conditioner can be provided in a ceiling part directly below the air conditioner or a wall part in the building.

In such a configuration, if an air conditioner with a return air suction port attached, for example, a built-in type is adopted, it is not necessary to separately construct a return air suction port. Also, when installing a return air suction port on the wall, it is possible to install the suction port at any position on the wall by connecting the air conditioner and the suction port with a ductless space inside the wall. Therefore, the degree of freedom in design is improved.

Further, when the inside of the wall portion is a ductless space, if the ductless space is projected to the outer wall side of the building, it is possible to avoid pressure on the living room space in the building.

In the air conditioning system, the opening may be provided with an opening adjustment mechanism capable of increasing or decreasing the ventilation flow rate of the outlet.

With such a configuration, the opening adjustment mechanism is operated in response to the request of the air conditioning target area in the building to increase or decrease the ventilation flow rate of the air outlet, thereby appropriately adjusting (setting) the air volume of the conditioned air. be able to. Further, if the minimum opening is secured so that the opening adjustment mechanism is not fully closed, it is possible to continue supplying the required amount of outside air.

Further, if the ventilation path is filled with conditioned air by reducing the opening degree of the opening adjustment mechanism, heat radiation is generated from the ceiling surface or the floor surface facing the ventilation path. Radiant air conditioning is possible. The opening adjustment mechanism may be a manual type, but infrared communication, a wired remote controller, or other operating means, which is advantageous in terms of cost, can be adopted.

In the entire building air conditioning system, a sub air supply passage communicating with the air supply passage or a sub return air passage communicating with the return air passage can be provided in the wall portion of the building.

With such a configuration, the degree of freedom in the positions where the conditioned air outlets and the suction ports for sucking the air in the building are installed is increased. Further, if the opening adjustment mechanism is provided at the air outlet and the suction port, the conditioned air can be supplied from the upper portion of the air conditioning target area during cooling and the lower portion of the air conditioning target area during heating. This makes it possible to realize an air-conditioning environment with head heat and foot heat, which improves comfort.

In the whole building air conditioning system, a booster fan may be provided at the air outlet.

With such a configuration, by operating the booster fan as necessary, it is possible to adjust the air volume according to the preference of the occupant in the air conditioning target area.

In the entire building air conditioning system, the ventilation device can be arranged in a region of the wall portion in the building near the floor surface.

With such a configuration, it is not necessary to use a stepladder or the like when performing maintenance on the ventilation device, so that the worker can safely perform the work.

In the whole building air conditioning system, the ventilation device can be arranged in a storage room provided in the building.

With such a configuration, the ventilation device can be concealed in the storage room, so that the interior of the building can be finished with a neat appearance. Further, since the storage room can be used as a duct route or the like, construction becomes easy. If the return air port is provided on the front door of the storage room (for example, the opening/closing door surface of the closet) and the storage room is a ductless return air path, the construction can be simplified.

According to the present invention, it is possible to provide an entire building air conditioning system that has both an air conditioning function and a ventilation function, is easy to install, and does not require duct maintenance.

It is possible to adjust the air volume according to the preference of the occupants of the living rooms 3 and 4, which are the target areas.

In addition, like the whole building air conditioning system 101, 102, 103, 104, 105, 106, 107 shown in FIGS. 1 to 7, air is supplied to the space above the ceiling 7, 8, 47, 59, 67, 77 (ductless space). When used as a route, it is preferable to improve airtightness and heat insulation. As an example, if the foam spray insulation is applied to the space above the ceiling 7, 8, 47, 59, 67, 77 (ductless space), the airtight heat insulation performance can be ensured relatively easily.

In the whole building air conditioning system 101, 102, 103, 104, 105, 106, 107 shown in FIGS. However, in reality, there is a region in the building that connects the first and second floors, such as a staircase (not shown), through which air from both the first and second floors is sucked.

As described above, in the entire building air conditioning system 101, 102, 103, 104, 105, 106, 107 shown in FIGS. 1 to 7, the ventilation device 2 is installed on the first floor of the building, but it is not limited to this. Therefore, in the air conditioning system according to the present invention, although not shown, the ventilation device may be arranged in a storage room provided in the building.

With such a configuration, the ventilation device can be concealed in the storage room, so that the interior of the building can be finished with a neat appearance. Further, since the storage room can be used as a duct route or the like, construction becomes easy. If the return air port is provided on the front door of the storage room (for example, the opening/closing door surface of the closet) and the storage room is a ductless return air path, the construction can be simplified.

Next, the entire building air conditioning system 108 will be described with reference to FIG. As shown in FIG. 8, the entire building air conditioning system 108 includes air conditioners 1a and 1b, a ventilation device 2, and conditioned air supplied from the air conditioners 1a and 1b in the building 18 via ducts D1 and D2. A plurality of outlets 85 and 86 are provided to blow out toward the interiors of the living rooms 3 and 4, which are target areas.

The air conditioners 1a and 1b are respectively arranged in the ceiling spaces 7 and 8 in the building 18, and the ceiling spaces 7 and 8 are provided for the return air suction provided in the ceiling portions C1 and c2 of the living rooms 3 and 4, respectively. It is a return air path that takes in the air in the living rooms 3 and 4 from the mouths 10a and 10b and guides it to the air conditioners 1a and 1b. When the space above the ceiling (ductless space) is used as the return air passage, airtightness is not required as much as when it is used as the air supply passage. However, the airtightness is not required so much between the ductless space and the living room, and the airtightness is required between the ductless space and a place other than the living room (such as a wall or floor).

Since the entire building air conditioning system 108 includes the air conditioners 1a and 1b and the ventilation device 2, it is possible to exhibit both the air conditioning function and the ventilation function. Moreover, since duct construction between the air conditioners 1a and 1b and the suction ports 10a and 10b is unnecessary, the man-hours are simplified, the construction is easy, and the return air duct itself can be eliminated. No duct maintenance is required.

In the entire building air conditioning system 108, the outside air sucked in by the ventilation device 2 is supplied to the air conditioners 1a, 1b by flowing into the above-ceiling spaces 7, 8 via the ventilation path 9, so that the required ventilation effect is obtained. It can be surely obtained, and the ventilation efficiency is also improved. In addition, since the conditioned air formed by the air conditioners 1a and 1b is supplied to the living rooms 3 and 4 via the ducts D1 and D2, heat loss can be reduced.

The whole building air conditioning systems 101, 102, 103, 104, 105, 106, 107, 108 described with reference to FIGS. 1 to 8 are examples of the whole building air conditioning system according to the present invention, and the whole building of the present invention is illustrated. The air conditioning system is not limited to the above-mentioned whole building air conditioning system 101, 102, 103, 104, 105, 106, 107, 108.
