The present invention relates to an air conditioning system and a house. In particular, the present invention relates to an air conditioning system and a house that air-conditions a room without requiring complicated duct piping in a highly airtight and highly heat-insulated detached house.

Now that the depletion of fossil fuels, air pollution caused by the use of large amounts of fossil fuels, and global warming caused by carbon dioxide have become major social problems, the need for energy conservation is increasing. In particular, energy consumption in houses and buildings is increasing as the tendency to desire a comfortable living space using air conditioning is increasing, so energy saving by making buildings highly airtight and highly heat-insulated is required.

It is said that the entire building can be air-conditioned to maximize the advantages of a highly airtight and highly insulated house. A next-generation air-conditioning system that enables energy-saving and comfortable indoor environment has been proposed, which can be used for heating and cooling with a single wall-mounted room air conditioner on the market, and at the same time can perform ventilation, air purification, humidification, and dehumidification. For example, Patent Document 1 and Patent Document 2). In this whole building air conditioning system, for example, as shown in FIG. 7, ducts are stretched around all rooms like octopus legs, and air is circulated by the ducts to perform ventilation and air conditioning (cooling, heating).

Japanese Patent No. 5094894 Japanese Patent No. 5067769

However, in this whole building air conditioning system, since the air is routed by a duct, the certainty is high from the viewpoint of ventilation, but there are the following drawbacks.
For example, ducts must be stretched across all rooms like octopus legs, which complicates piping and makes initial investment expensive. The exchange efficiency of the total heat exchange device itself of the air conditioning unit has been improved by the performance improvement in recent years, but the heat exchange efficiency of the entire room is limited due to the structure. In addition, maintenance is troublesome and costly, such as having to replace the filter on a regular basis.
In addition, if the temperature difference between a comfortable living room with heating / cooling and a dressing room or bathroom without heating / cooling is large, it makes you feel uncomfortable every time you move, and the thermal efficiency is poor. Especially in the cold season, there is also the problem of so-called heat shock for the elderly.

The present invention has been proposed in view of such conventional circumstances, and an object of the present invention is to save energy by excellent heat insulating performance without the need for complicated duct piping in a building such as a detached house. It is an object of the present invention to provide an air conditioning system and a house which can realize reduction of heat loss, eliminate temperature difference, and make the whole house uniform and comfortable temperature.

As a result of diligent studies, the present inventors supplied warm air warmed by the temperature / humidity control device arranged in the underfloor space to the living space through the ventilation holes in the cold season, and also in the warm season. The present invention was completed based on the idea that the above object can be achieved by supplying the cold air cooled by the temperature / humidity control device arranged in the back space of the cabin to the living space through the ventilation holes.

The ventilation system of the present invention includes one or more floors, a roof or a ceiling, and a wall, and is a living space surrounded by the floor, the roof, and the wall, and the lowest layer of the floor. It is applied to a detached house (house) having an underfloor space defined under the floor and a hut back space defined directly under the roof.
In the following explanation, a two-story house will be taken as an example, but if the house has an underfloor space, the book may be a one-story (one-story) house or a three-story or more house. The invention is applicable as well.
1 to 5 are views showing an example of a house to which the ventilation system of the present invention is applied, FIG. 1 is a front view and a side view showing the overall appearance, FIG. 2 is a first floor plan view, and FIG. 3 is 2. The floor plan and FIG. 4 are the plan view of the back of the cabin. FIG. 5 is a cross-sectional view taken along the line XX in FIG. 2 for explaining the flow of air in the ventilation system of the present invention.

The house 1 includes a foundation portion 10, a floor portion (first floor portion 20, second floor portion 21, third floor portion 22), a wall portion 30, a wife wall portion 31 (wall portion directly under the eaves), and a roof portion. Has 40. The space surrounded by the foundation portion 10 and the first floor portion 20 forms the underfloor space 11, and the space surrounded by the floor portions 20, 21 and 22, and the wall portion 30 is the living space 23, 24 (1). It forms the living space 23 on the second floor and the living space 24) on the second floor. The space surrounded by the floor portion 22, the roof portion 40, and the wall portion 30 forms the cabin back space 41 (loft space). The ceiling portion (floor portion 22) may not be stretched and the roof portion 40 may be open. The living spaces 23 and 24 are divided into a plurality of rooms or corridors by a partition wall 32. Further, a staircase connecting the first floor, the second floor, the second floor and the loft is provided to form a staircase room 28. Further, a stairwell 29 penetrating the first floor and the second floor may be provided.
In the following description, the inside of the house 1 including the above-mentioned underfloor space 11, living spaces 23 and 24, and the cabin back space 41 is referred to as “indoor”, and the outside of the house 1 is referred to as “outdoor”.

In the air conditioning system of the present embodiment, the temperature / humidity control devices 12 and 42 are arranged in the underfloor space 11 and the cabin back space 41, respectively. In the cold season, the warm air warmed by the temperature / humidity control device 12 arranged in the underfloor space 11 is supplied to the living spaces 23 and 24 through the vents. Further, in the warm season, the cold air cooled by the temperature / humidity control device 42 arranged in the cabin back space 41 is supplied to the living spaces 23 and 24 through the vents.
In the present embodiment, the temperature / humidity control devices 12 and 42 are arranged only in the underfloor space 11 and the cabin back space 41. No temperature / humidity control device is installed in each room. Since only two temperature / humidity control devices, the underfloor space 11 and the cabin back space 41, are required, the initial cost and running cost can be reduced.
As such temperature / humidity control devices 12 and 42, a heat dissipation type heating system or the like may be used, but an air conditioner is preferable because air can be efficiently cooled and heated.

In particular, the house 1 to which the ventilation system of the present invention is applied is preferably a highly airtight and highly insulated house.
Specifically, in the house of the present embodiment, it is preferable that the entire surface of the foundation portion 10, particularly the foundation slab, has a heat insulating structure. In the past, heat was taken away by the exposed foundation slab, and it took time to warm up, resulting in a large loss of energy. Since the entire surface of the foundation slab has a heat insulating structure, heating energy can be used efficiently. The total insulation of such a foundation slab is particularly effective for heating by general intermittent operation other than in cold regions.
Further, it is preferable that the roof portion 40 is also highly heat-insulated. Energy can be efficiently used without letting the heat of the warm air rising from the underfloor space 11 escape.

In FIG. 5, the flow of warm air is indicated by a solid arrow. In the ventilation system of the present embodiment, a temperature / humidity control device 12 (for example, an air air conditioner) is arranged in the underfloor space 11, and the air is warmed by the temperature / humidity control device 12 in the cold season. Then, the warmed air (warm air) is supplied from the underfloor space 11 to the living spaces 23 and 24. That is, one temperature / humidity control device 12 arranged in the underfloor space 11 heats the entire house. By arranging the temperature / humidity control device 12 in the underfloor space 11 which is narrower than the living spaces 23 and 24, the thermal efficiency is improved. Further, by arranging it in the underfloor space 11, there is no problem of noise.
In particular, for example, when the building is made of RC (reinforced concrete), the heat capacity of RC can be utilized by arranging the temperature / humidity control device 12 in the underfloor space 11, and the heat storage property of the house 1 can be enhanced. ..
Furthermore, since the entire surface of the foundation slab has a heat insulating structure, the underfloor air conditioning area can be highly heat-insulated, and heating energy can be efficiently used.
Since the temperature / humidity control device 12 is arranged in the underfloor space 11, an inspection port for maintenance of the temperature / humidity control device 12 is required.
By supplying the air (warm air) warmed in the underfloor space 11 to the living spaces 23 and 24 through the vents (for example, the louver 26 and the slit 27 described later), the warm air can be distributed to the entire house. In addition, since the floor is also warmed by the warm air under the floor, it is also effective as an inexpensive radiant floor heating system.

Further, the foundation portion 10 is provided with a ventilation port 13, through which fresh outdoor air is taken in (supply air) and indoor air is discharged to the outside (exhaust gas).
In the cold season, the warm air warmed by the temperature / humidity control device 12 arranged in the underfloor space 11 and the cold air supplied from the outside are mixed in advance in the underfloor space 11 to adjust the temperature to a predetermined temperature. , It is preferable to supply the living spaces 23 and 24.
If the warm air adjusted by the temperature / humidity control device 12 is supplied to the living spaces 23 and 24 as it is, the heat of the air flow (hot air) may be felt and it may be unpleasant. By supplying after mixing, the temperature of the air supplied to each space becomes close to the desired room temperature, the heat of the airflow is less likely to be felt, and comfort can be enhanced.

In FIG. 5, the flow of cold air is indicated by a dotted arrow. In the ventilation system of the present embodiment, a temperature / humidity control device 42 (for example, an air conditioner) is arranged in the cabin back space 41, and the air is cooled by the temperature / humidity control device 42 in the warm season. Then, the cooled air (cold air) is supplied from the cabin back space 41 to the living spaces 23 and 24 through the vents. That is, the entire house is cooled by one temperature / humidity control device 42 arranged in the cabin back space 41. By cooling the air in the attic space 41 and cooling the ceiling, inexpensive cold radiation can be realized. Further, by cooling the upper parts of the living spaces 23 and 24, the comfort can be enhanced by the cold foot heat. Then, by supplying the cooled air (cold air) to the living spaces 23 and 24, the cold air can be distributed to the entire house. The cold air is supplied to the living spaces 23 and 24 through the vents (for example, the louver, the floor grid 22a and the slit 27 described later).

It is preferable that the cabin back space 41 is provided with a pipe fan 43 (ventilation fan), and cold air is sent to the cabin back space 41 by the pipe fan 43. By providing the pipe fan 43, cold air can be reliably sent to the partitioned cabin back space 41.
Further, by providing the pipe fan 43, air circulation can be promoted even in the cold season and the intermediate season, and the indoor air can be kept fresh.

A ventilation port (not shown) is provided in the vicinity of the roof portion 40, and fresh outdoor air is taken in through this ventilation port (supply air). Indoor air is exhausted from each room to the outside (exhaust). Then, for example, a switching damper (not shown) is provided in the vicinity of the heat exchange ventilation device of the underfloor space 11, and the fresh air supplied is sent to the underfloor space 11 and to the cabin back space 41. However, it can be switched by the switching damper.
In the warm season, the cold air cooled by the temperature / humidity control device 42 arranged in the cabin back space 41 and the warm air supplied from the outside are mixed in advance in the cabin back space 41 to adjust to a predetermined temperature. It is preferable to supply air to the living spaces 23 and 24.
If the cold air adjusted by the temperature / humidity control device is supplied to the living spaces 23 and 24 as it is, it may be unpleasant to feel the coldness of the air flow (a feeling of tingling), but by supplying the cold air after mixing it with the outside air. , The temperature of the air supplied to each space becomes close to the desired room temperature, it is difficult to feel the coldness of the air flow, and the comfort can be enhanced.

As shown in FIG. 4, a part of the third floor portion 22 is a floor grid 22a as a vent for passing air in the vertical direction. As shown in FIGS. 2 and 3, the first floor portion 20 and the ceiling portion are provided with ventilation holes 26 and 27, respectively, for allowing air to pass in the vertical direction.
The positions where the vents 26 and 27 are provided are not particularly limited, but are arranged at the edge of the room, particularly on the outer wall side, so that the vents 26 are not covered with carpet, furniture, or the like. Is preferable.
It is preferable that at least one ventilation holes 26 and 27 are provided in each of the partitioned rooms, and it is preferable that the ventilation holes 26 and 27 are arranged as evenly as possible along the outer wall when viewed from the entire floor. As a result, air can be circulated uniformly on each floor.

Specifically, the vents 26 and 27 are a louver 26 provided in the first floor portion 20 and a slit 27 provided in the ceiling portion. The warm air from the underfloor space 11 is supplied to each room through the louver 26, and the cold air from the cabin back space 41 is supplied to each room through the floor grid 22a and the slit 27.
Further, for example, as shown in FIG. 6, in the first floor portion 20, a vent 34 for passing warm air from the underfloor space 11 may be provided between the baseboard portions 33a and 33b and the wall portion 30. ..
As shown in FIG. 2, it is preferable that the louver 26 is arranged not only in a living room such as a living room but also in a dressing room, a corridor, a toilet, and the like. By warming the dressing room, corridor, toilet, etc. to eliminate the temperature difference in the room, it is possible to eliminate the discomfort caused by the temperature difference when moving the room, and in particular, to prevent heat shock. By supplying warm air through the louver 26, warm air can be slowly circulated throughout the house.
As shown in FIG. 3, the slit 27 is preferably provided on one surface of the section along the wall. By providing the slit 27 along the wall, the entire wall surface can be cooled and the cooling efficiency can be improved. In addition, the comfort can be improved because the cold air can be supplied without feeling the cold air flow.

Further, the staircase 28 in which the stairs connecting the lower floor and the upper floor are arranged plays a great role in the movement of air. Further, if there is a stairwell 29 connecting the upper floor and the lower floor separately from the staircase 28, it is preferable because the air can be moved more efficiently. From the viewpoint of uniform air circulation, it is preferable that the staircase 28 and the atrium 29 are as far apart as possible. With a large space such as the staircase 28 and the atrium 29, comfortable air can be gently distributed throughout the house.

In a house to which the ventilation system of the present embodiment is applied, the roof portion 40 is preferably a so-called gable roof in which two inclined surfaces are combined in a mountain shape. Further, it is preferable that the ventilation port is provided in the vicinity of the highest portion of the roof portion 40. By forming the roof portion 40 into a gable structure, an air flow can be formed along the slope of the roof portion 40, and ventilation from the ventilation port (particularly, exhaustion of dirty air) can be efficiently performed.

Further, for example, a ventilation port is provided on the ceiling of each room (not shown). At this time, it is preferable that the ceiling portion is inclined so that the ventilation port side is higher. An air flow can be formed along the slope of the ceiling portion, and ventilation from the ventilation port (particularly, exhaustion of dirty air) can be efficiently performed. The ventilation openings provided in each room are mainly suction ports for exhaust air, not for air supply. There is no discomfort because you do not feel the airflow caused by the air supply.
The ventilation openings from each room are connected to the ventilation openings through ducts (not shown).

As described above, in the air conditioning system of the present invention, in the cold season, the warm air warmed by the temperature / humidity control device arranged in the underfloor space is supplied to the living space through the ventilation holes provided in the floor portion. .. In the warm season, the cold air cooled by the temperature / humidity control device arranged in the back space of the cabin is supplied to the living space through the ventilation holes.
As a result, in the air conditioning system of the present invention, the whole house can be made comfortable with one temperature / humidity control device without becoming too cold or too hot. In addition, the slow and comfortable airflow circulates throughout the highly insulated living space, so the temperature distribution is even and the entire house can be kept at a comfortable temperature.
Further, in the air conditioning system of the present invention, there is no need for complicated duct piping, energy saving can be realized by excellent heat insulating performance, and heat loss can be reduced. By not arranging complicated ducts, the structure is simplified, and the initial cost and maintenance work can be reduced, which is a great merit. In addition, there is no need for complicated duct work, and there are fewer restrictions on the floor plan.

Although the embodiments of the present invention have been described above, the present invention is not limited to this, and can be appropriately changed without departing from the spirit of the invention.

By using the air-conditioning system according to the present invention, energy saving can be realized and heat loss can be reduced, and it can be widely used as a whole building air-conditioning system in a highly airtight and highly insulated house.
