JP 2002-70193 A JP-A-3-99147

  The “underfloor ventilation structure of the building” described in Patent Document 1 uses the underfloor space as an exhaust path, and only one air conditioner is installed in the cabin space. Since the air conditioning capacity of one building is secured, the air conditioner becomes large in size, and it is necessary to secure the installation location in the space behind the shed, which makes construction difficult. Moreover, since the ventilator is concealed in the ceiling, the installation work for hanging is troublesome.

  The “forced ventilation type house” described in Patent Document 2 has a ventilation device installed in the underfloor space and ventilates the room by using the underfloor space as an exhaust path, but has an air conditioning function. Not.

  Therefore, the problem to be solved by the present invention is to provide an air conditioning system that has an air conditioning function and a ventilation function, is easy to construct, can be easily applied to a building, and can reduce the load on the air conditioner. There is to do.

The entire building air conditioning system according to the present invention is:
An air conditioner placed in the ceiling space or ceiling surface of the building;
A ventilation device disposed in the underfloor space of the building;
An air supply port provided in each room in the building for supplying conditioned air supplied from the air conditioner into the building;
An exhaust port provided on the first floor in the building for discharging air in the building via the underfloor space,
The ventilator is
A function of sucking air in the underfloor space and discharging it outside the building;
A function of sucking air outside the building and feeding it to the air conditioner;
It is characterized by having.

  As described above, since the ventilation device is installed in the under-floor space, it is difficult for the driving sound to be transmitted to the room, so that the room space can be quiet. Moreover, since the space under the floor is used, it is not necessary to provide a dedicated installation space, and no separate construction work is required.

  Furthermore, by using the underfloor space as an exhaust path, it is possible to simultaneously perform underfloor ventilation while air-conditioning the entire building, and the underfloor space is almost the same as the living room space by passing the air-conditioned exhaust through the underfloor space. Air conditioning load is reduced in a near environment. Further, the deterioration of the building due to humidity and the like can be suppressed, and the installation environment of the ventilation device is improved, so that the product life of the ventilation device itself is not impaired.

  In addition, by using the underfloor space as an exhaust path, ventilation of the underfloor space can be performed at the same time while air-conditioning the entire building, and the underfloor space is formed by passing the air-conditioned exhaust through the underfloor space. Since the environment is almost the same as the living room space, the air conditioning load can be reduced.

  Here, in the whole building air conditioning system, the ventilation device has a function of exchanging heat between the air in the building sucked through the underfloor space and the air sucked from outside the building. It is desirable.

  With such a configuration, it is possible to introduce the air sucked from outside the building into the building in a state close to the room temperature (air conditioning temperature) in the building, which is effective in improving the air conditioning efficiency.

Further, in the entire building air conditioning system, the air conditioner is disposed in a ceiling space formed at a position lower than the ceiling surface of the common part in the building,
It can be set as the structure which provided the said air supply opening in the part located in the shortest distance from the said air conditioner in the said room.

  With such a configuration, an air conditioner installation space can be easily secured, and there is no need to separately provide an air conditioner room. In addition, by installing the air conditioner in a common part that is a non-residential room, it becomes difficult for the operating sound of the air conditioner to reach the living room, so that it is possible to provide a whole building air conditioning system that is quiet for residents.

  In addition, by installing an air conditioner in the common area, the distance to the air inlet in each room is the shortest and the duct route is also shortest, resulting in low pressure loss and reducing the load on the air conditioner. By being the shortest, the duct material cost can be minimized, the construction can be simplified, and the cost can be reduced.

  In the entire building air conditioning system, the air supply port is preferably a line-type air outlet.

  With such a configuration, since the pocket size of the falling ceiling can be minimized, the space in the building can be used to the maximum, and airflow can be blown out along the ceiling and walls in the building. As a result, air-conditioned air is distributed throughout the living room, improving air-conditioning efficiency. Moreover, when the air conditioner is lowered and installed on the ceiling, the air conditioner can be installed on the upper part of the indoor wall surface, so that it is comfortable and the airflow switching operation can be easily performed.

In the entire building air conditioning system, the upstream side of the line-shaped outlet is connected to the air conditioner through a chamber and a duct,
The chamber may have a portion that continuously widens in the horizontal direction and a portion that continuously shrinks in the vertical direction as it goes from the connection port with the duct toward the line outlet.

  With such a configuration, the chamber can be installed in the building without being obstructed by the building structure of the building, so the air conditioner installed on the falling ceiling, the line-shaped air outlet installed on the wall surface, Can be suitably connected. In addition, the conditioned air supplied from the duct smoothly flows to the line-type outlet through the chamber having the above-described shape, so that a low-pressure loss can be achieved.

  In the whole building air conditioning system, it is desirable that the line-shaped air outlet has one or a plurality of rotary curved blades capable of adjusting the air direction and the air volume.

  With such a configuration, the air volume adjustment and the wind direction adjustment can be performed by operating only one or a plurality of curved blades, so that the structure can be simplified.

  The whole building air conditioning system preferably has a mechanism for holding an opening capable of supplying a predetermined air volume when the line-shaped air outlet is closed.

  With such a configuration, since the air conditioning channel can be used as a ventilation channel, a 24-hour ventilation function is ensured even in seasons where air conditioning is not required, such as an intermediate period between summer and winter. be able to.

  In the whole building air conditioning system, an outside air purifying means for purifying outside air taken into the ventilator can be disposed under the floor space or between the floors.

  With such a configuration, maintenance of the outside air cleaning means (for example, the filter box) can be performed from an inspection port provided on the floor surface in the building, and workability is improved.

  In the whole building air conditioning system, a pipe fan for drawing the conditioned air of the common part into the dressing room can be provided on the wall between the dressing room and the common part provided in the building.

  With such a configuration, the air-conditioned air can be drawn into the dressing room from the common part without performing duct construction in the dressing room. In addition, the power of the pipe fan can be used to make the inside of the dressing room the same environment as the air-conditioned space, which is effective for energy saving.

  In the whole building air conditioning system, it is possible to provide an intermediate duct fan capable of reversible operation which connects the ceiling space of the building and the room in a communicating state.

  With such a configuration, warm air in the ceiling space can be supplied into the room in winter, and cold air in the room can be supplied into the ceiling space in summer. Effective for mitigation.

  According to the present invention, it is possible to provide an entire building air conditioning system that has an air conditioning function and a ventilation function, is easy to construct, can be easily adopted in a building, and can reduce the load on the air conditioner.

  Hereinafter, based on FIGS. 1-14, the whole building air conditioning system 100 which is embodiment of this invention is demonstrated. 1 and 2 show a schematic configuration of the entire building air conditioning system 100 according to the embodiment of the present invention, and FIGS. 3 to 5 show an actual building H equipped with the entire building air conditioning system 100. The members having the same structure and the same function have the same reference numerals. Moreover, the area | region which attached | subjected the mesh in FIG. 3, FIG. 4 represents the falling ceiling 11c, 12c.

  As shown in FIGS. 1 and 2, the entire building air conditioning system 100 according to the present embodiment includes an air conditioner 10 disposed on the lower ceilings 11 c and 12 c of the shared portions 11 and 12 on the first floor and the second floor of the building H, respectively. 20, the ventilation device 30 arranged in the underfloor space 13 of the building H, and the rooms R 11, R 12, R 21, in the building H in order to supply the building H with conditioned air supplied from the air conditioners 10, 20. Since the air in the building H is exhausted through the line-type air outlets 14, 14, 14, 14 and the underfloor space 13 provided in the R22, the floor surface F1 on the first floor in the building H And the exhaust ports 15 and 15 provided in. An outdoor unit 21 is arranged outside the building H.

  The ventilation device 30 has a function of discharging the air in the building H sucked from the duct 16 through the underfloor space 13 to the outside of the building H through the duct 17 and the outside of the building H taken in through the duct 18. A function of supplying air (outside air) to the air conditioners 10 and 20 via the air supply ducts 19a and 19b, respectively. In the middle of the duct 18, a filter box 44 having a built-in filter that is an outside air cleaning means for purifying outside air taken into the ventilation device 30 is disposed.

  In the entire building air conditioning system 100, air supply ports 14 for supplying conditioned air from the air conditioners 10 and 20 are provided in the rooms R11, R12, R21, and R22 in the building H, and the interiors of the rooms R11, R12, R21, and R22 are provided. The exhaust discharged from the air is exhausted through the undercut U at the lower edge of the door, through the exhaust port 15 of the floor surface F1 on the first floor, and through the underfloor space 13 which is airtightly finished.

  The air supply ducts 19a and 19b of the ventilation device 30 are connected to the air conditioners 10 and 20, and supply the outside air to the air conditioners 10 and 20, respectively. The ventilation device 30 is installed in the underfloor space 13 on the first floor, the exhaust from the room is taken into the underfloor space 13 through the exhaust port 15 installed on the floor surface F1 of the first floor, and the underfloor space 13 is connected to the ductless exhaust path. Use as

  As described above, since the ventilation device 30 is installed in the underfloor space 13, the operation sound of the ventilation device 30 becomes difficult to be transmitted to the room, and therefore, the indoor space (inside the rooms R11, R12, R21, R22 and the common parts 11, 12). ) Can be kept quiet. Moreover, since the ventilator 30 is arranged using the underfloor space 13, there is no need to provide a dedicated installation space for the ventilator 30, and no separate construction work is required.

  Furthermore, by using the underfloor space 13 as an exhaust path, the entire underfloor space 13 can be ventilated while the entire building H is air-conditioned, and the air-conditioned exhaust passes through the underfloor space 13. In addition, since the underfloor space 13 becomes an environment that is almost similar to the living room space (inside the rooms R11, R12, R21, and R22), the air conditioning load can be reduced, and deterioration of the building due to humidity and the like can be suppressed. it can. Since the installation environment of the ventilation device 30 is also improved, the product life of the ventilation device 30 itself is not impaired.

  As shown in FIG. 1, the inspection port 45 formed on the floor surface F <b> 1 of the room R <b> 11 can be used as the inspection port of the ventilation device 30. When the entire building air conditioning system 100 is constructed in a snowy area, a ventilator 30 is installed between the first floor and the second floor of the building H so as not to be affected by snow, and vent caps (ducts 17, 18). The caps of the openings 17a and 18a) can also be mounted at a high place. In addition, when the ventilator 30 is installed in the underfloor space 13 of the kitchen K (see FIG. 3) in the building H, the opening / closing port 46 (see FIG. 3) of the underfloor storage can also be used as an inspection port.

  In the entire building air conditioning system 100, the ventilation device 30 disposed in the underfloor space 13 is a total heat exchanger, and air (exhaust) in the building H sucked in via the underfloor space 13 and air taken from outside the building H. It has a function of exchanging heat with (outside air).

  Therefore, it is possible to introduce the air sucked from outside the building H via the duct 18 into the building H in a state close to the room temperature (air conditioning temperature) in the building H, which is effective in improving the air conditioning efficiency. It is.

  In the entire building air conditioning system 100, the air conditioners 10 and 20 are disposed in the ceiling back spaces 11a and 12a above the falling ceilings 11c and 12c formed in the common portions 11 and 12 in the building H, respectively, and the room R11. , R12, R21, R22, air supply ports 14 are provided in portions located at the shortest distance from the air conditioners 10, 20 on each floor.

  Specifically, the air supply port 14 can be provided on the upper surface of the wall surface W on the corridor 22 side or on the ceiling surface C on the corridor 22 side of each room R11, R12, R21, R22. If a thin air conditioner such as an amenity built-in type is adopted as the air conditioner, the air conditioner fits well while minimizing the falling dimensions of the falling ceilings 11c and 12c, and the space of the common parts 11 and 12 is tight. Never give. Moreover, the storage room 29 etc. can be provided in the shed space 40 and space can be used effectively.

  As shown in FIG. 1, when the building H is a multi-storey house, the air conditioners 10 and 20 are provided in the ceiling space 11a and 12a of the common portions 11 and 12 on each floor. When the resident is absent and air conditioning is not required, the operation of the floor can be stopped, which can contribute to energy saving. In addition, since the ventilation operation (24-hour ventilation) is performed even if the air-conditioning operation is stopped, the ventilation obligation of the Building Standard Law can be cleared.

  With the above-described configuration, the entire building air conditioning system 100 can be easily installed because it is not necessary to separately provide an air conditioner room. In addition, by installing the air conditioners 10 and 20 in the ceiling space 11a and 12a of the common parts 11 and 12 which are non-residential rooms, it is possible to prevent the operation sound of the air conditioners 10 and 20 from diffusing. It can provide a quiet air conditioning system for the entire building.

  Furthermore, by installing the air conditioners 10 and 20 in the ceiling space 11a and 12a of the common portions 11 and 12, the distance between the air supply port 14 of each room R11, R12, R21 and R22 and the air conditioners 10 and 20 can be set. Since it can be the shortest and the route of the duct 23 is also shortest, a low-pressure loss occurs, and the loads on the air conditioners 10 and 20 can be reduced. Further, since the route of the duct 23 is the shortest, the cost of the duct material can be minimized, the construction can be simplified, and the cost can be reduced.

  As shown in FIGS. 1 and 2, in the entire building air conditioning system 100, a line-type outlet 14 is used as an air inlet to each room R <b> 11, R <b> 12, R <b> 21, R <b> 22, and the upstream side of the line-type outlet 14. Is connected to the air conditioner 10 through the chamber 24 and the duct 23. As shown in FIG. 8, the chamber 24 includes a portion that continuously widens in the horizontal direction as it goes from the connection port 25 to the duct 23 toward the line outlet 14, and a portion that continuously shrinks in the vertical direction. The rectifying unit 26 is also provided.

  In the entire building air conditioning system 100, the line-shaped air outlet 14 as shown in FIG. 9 is used as an air supply port for supplying the conditioned air supplied from the air conditioners 10 and 20 to the room R11 and the like. The pocket size of the ceilings 11c and 12c can be suppressed to the minimum size. Moreover, since the line-shaped blower outlet 14 can blow off the conditioned air along the ceiling or the wall surface, the conditioned air spreads throughout the room, improving the air conditioning efficiency.

  In the entire building air conditioning system 100, by using the chamber 24 as shown in FIG. 8, the air conditioner 10 installed on the falling ceilings 11c and 12c and the line-shaped outlet 14 installed on the wall surface W are suitably connected. can do. In addition, the chamber 24 does not interfere with various members (beams and the like) constituting the descending ceilings 11c and 12c, and the chamber 24 has a good fit.

  Furthermore, the conditioned air supplied from the duct 23 can smoothly reach the line-type outlet 14 by flowing in the chamber 24 having the above-described shape, so that a low-pressure loss can be achieved. The chamber 24 is fixed to the constituent members of the building H using screws (not shown) or the like by attaching L-shaped metal fittings 24a with long holes, which are detachably attached to both side surfaces thereof. It can be installed at a predetermined place.

  As shown in FIGS. 9 and 10, the line-type air outlet 14 has a rotating curved blade 14 </ b> X capable of adjusting the air direction and the air volume. The curved blades 14X include a shallow bowl-shaped main body portion 14a, a fan-shaped side plate 14b that closes both ends of the main body portion 14a, and a plurality of arranged at regular intervals in a direction crossing the concave curved surface of the main body portion 14a. Rib 14c. The curved blades 14X are rotatably held in a rectangular tube-shaped frame 14e via support shafts 14d protruding in the horizontal direction from the side plates 14b at both ends of the main body 14a. The front edge portion 14f of the curved blade 14X serves as a manual operation portion when the curved blade 14X is rotated.

  Even in the state shown in FIG. 10A, the front edge portion 14f of the curved blade 14X protrudes from the front portion of the line-shaped air outlet 14 toward the room R12, so that it can be easily manually operated from the room R12 side. it can. The plurality of ribs 14c arranged at a predetermined interval on the concave curved surface of the main body portion 14a have a function of reinforcing the main body portion 14a and a function of rectifying an air flow, which will be described later.

  In the line-type air outlet 14, the air volume adjustment and the air direction adjustment can be performed by rotating only one curved blade 14X about the support shaft 14d, so that the structure can be simplified. . Further, when the air conditioner 10 is lowered and installed in the ceiling space 11a, 12a above the ceilings 11c, 12c, the line-shaped air outlet 14 can be installed on the upper surface of the wall surface W, so that it is comfortable and the airflow switching operation is easy. It can be carried out.

  As shown in FIG. 10 (a), when the front edge portion 14f of the curved blade 14X is pushed into the front surface of the frame 14e, the line-shaped air outlet 14 is closed, but the rear portion of the main body portion 14a. Since the gap G is secured between the edge portion 14g and the inner surface of the frame 14e, an air flow can pass through the line-shaped outlet 14. Even when the front edge portion 14f of the curved blade 14X is pushed in until it approaches the front surface of the frame 14e, the front edge portion 14f is kept protruding from the front surface of the frame 14e.

  As shown in FIG. 10B, when the front edge portion 14f of the curved blade 14X is slightly pulled out from the front surface of the frame 14e, the front edge portion 14f and the rear edge portion 14g of the curved blade 14X are set so as to be positioned on the same horizontal plane. The conditioned air is blown out in the horizontal direction from the line-shaped outlet 14. At this time, as shown in FIG. 11, the conditioned air travels along the ceiling C in the air conditioned room (room R12), reaches the wall W1 on the opposite side of the wall W, and then circulates in the room R12. To flow. Therefore, it is desirable to set the curved blade 14X of the line-shaped outlet 14 in the state shown in FIG. 10B during the cooling operation in summer.

  As shown in FIG. 10 (c), when the front edge portion 14f of the curved blade 14X is pulled out from the front of the frame 14e and lowered to the lowest position, the entire curved blade 14X is exposed, and the conditioned air is the main body portion of the curved blade 14X. It is guided by the concave curved surface portion of 14a and the rib 14c, and is blown out downward from the line-shaped outlet 14. At this time, as shown in FIG. 12, the conditioned air descends toward the floor surface F1 in the air-conditioned room (room R12), flows toward the wall F1 opposite to the wall W, and flows along the floor surface F1. Accordingly, during the winter heating operation, it is desirable to set the curved blade 14X of the line-shaped outlet 14 in the state shown in FIG.

  As described above, in the entire building air conditioning system 100, even when the line-shaped outlet 14 is closed as shown in FIG. For this reason, a 24-hour ventilation function can be ensured even in a season where air conditioning operation is unnecessary, such as an intermediate period between summer and winter. In addition, since the ventilation air volume in 24-hour ventilation is about 0.5 times / h and is relatively small, the gap G is set as an opening area necessary for the air flow to spread throughout the room.

  As shown in FIGS. 1, 6, and 7, in the entire building air conditioning system 100, outside air cleaning means (filter box 44 with a built-in filter) for purifying outside air taken into the ventilation device 30 is disposed in the underfloor space 13. doing. For this reason, for example, the filter box 44 can be maintained from the inspection port 45 provided on the floor surface F1 in the building H, and the workability is also good. In addition, since the filter box 44 can be maintained from the floor F1, work at a high place using a stepladder or the like is unnecessary, and the filter box 44 is excellent in safety.

  Next, in the whole building air conditioning system shown in FIGS. 3 to 5, as shown in FIGS. 13 and 14, the common part 11 is placed on the wall W <b> 2 between the dressing room 42 provided in the building H and the common part 11. A pipe fan 28 for taking in the conditioned air into the dressing room 42 is provided.

  For this reason, conditioned air can be drawn in without installing a duct etc. in the dressing room 42. FIG. Moreover, since the inside of the dressing room 42 can be made the same environment as other air-conditioned spaces only by the air blowing capacity of the pipe fan 28, it is effective for energy saving.

  On the other hand, in the entire building air conditioning system 100, as shown in FIG. 1, an intermediate duct fan 41 capable of reversible operation is provided, which connects the cabin back space 40 of the building H and the room R21 in the building H in a communicating state. Yes. Accordingly, warm air in the attic space 40 can be supplied into the room R21 in the winter, and cold air in the room R21 can be supplied into the attic space 40 in the summer, thus reducing the air conditioning load. It is valid.

  As shown in FIGS. 1 and 4, since the storage room 29 provided in the cabin space 40 and the air conditioner 20 are communicated with each other by an air supply duct 43, air conditioning is performed from the air conditioner 20 into the storage room 29. By sending in air, the same air conditioning as other rooms can be performed.

  When constructing the entire building air conditioning system 100 as shown in FIG. 1, as the heat treatment means of the building H, a heat insulating material such as glass wool can be used, but from the viewpoint of ensuring airtightness, spray foaming heat insulation is constructed. It is desirable.

  Further, in the entire building air conditioning system 100, in order to efficiently exhaust the air in the building H to the outside of the building H via the underfloor space 13, it is an essential requirement to ensure the airtightness of the underfloor space 13 of the building H. For this reason, it is desirable to perform spraying foam heat insulation for the airtight heat insulation treatment means of the underfloor space 13.

  As described above, in the entire building air-conditioning system 100, the ventilation function by the ventilation device 30 can be secured by keeping the airtightness of the underfloor space 13 at a high level, whereby other functions (for example, line-type outlets) are secured. The cooling / heating function by the conditioned air blown out from 14 is also operated effectively.

  The whole building air conditioning system 100 described based on FIGS. 1 to 14 shows an example of the whole building air conditioning system according to the present invention, and the whole building air conditioning system according to the present invention is not limited to the whole building air conditioning system 100 described above. .

  INDUSTRIAL APPLICABILITY The present invention can be widely used in fields such as the housing construction industry as air conditioning and ventilation means for the entire building such as ordinary houses.
