[0003]

In a highly airtight and highly insulated house, as shown by the bold line in FIG. 2, the outer wall 10, ceiling 11, and floor 12 maintain the airtightness between the outside and the inside. It is difficult to keep the airtightness of the floor 12 sufficiently on the structure of the above.
In the underfloor 7, since ventilation is performed through the underfloor ventilation opening 9, there is a problem that indoor heat easily escapes to the outside through the floor and thermal efficiency deteriorates.

SUMMARY OF THE INVENTION The present invention has been made in view of the above description, and provides a ventilation air conditioning system capable of preventing indoor heat from escaping and improving thermal efficiency, and capable of performing underfloor ventilation and comfortable air conditioning. To be.

[0005]

According to a first aspect of the present invention, there is provided a ventilating air-conditioning system according to the first aspect of the present invention, in which a base is airtightly sealed, and a ventilation air conditioner performs planned ventilation and cooling / heating. A highly insulated house has two or more systems for blowing and controlling the conditioned air conditioned by the ventilation air conditioner 6, and one or more of the systems are located below the floor 7 or between floors such as between the first floor and the second floor. And blows it out to the back of the ceiling 13. Even if the floor 12 cannot be kept airtight by applying airtightness to the base 8 which is easily airtight,
The airtightness between the indoor and the outdoor can be secured to improve the thermal efficiency. In addition, the conditioned air is supplied under the floor 7 and under the ceiling 13.
, The underfloor 7 and the underside 13 can also be air-conditioned, and during cooling and heating, the underfloor 7 and the underside 13 can also be cooled and heated by radiant heat and heat transfer, so that air conditioning can be performed more comfortably. 7 below the floor
Even if the foundation 8 is made airtight by ventilating the air-conditioned air through the floor, ventilation under the floor can be performed. In addition, by ventilating the space above the ceiling 13, it is also possible to ventilate the space above the ceiling and perform ventilation behind the ceiling.

The ventilation and air conditioning system according to claim 2 of the present invention is characterized in that, in claim 1, the operation mode of the system that blows out the floor 7 and the ceiling 13 is only ventilation, dehumidification, and heating, and the cooling mode is eliminated. And Elimination of the cooling mode can prevent dew condensation on the floor and ceiling.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, the interior of a house 1 is divided into, for example, an LDK 2, a corridor / washroom 3, a second floor living room 4, a toilet 5, and the like. A foundation 8 such as a cloth foundation is provided around the underfloor 7 of the house 1, and the foundation 8 is kept airtight with the outside without providing a underfloor ventilation port as in the related art. In the house 1 of the present invention, as shown by the bold line in FIG. 1, the airtightness between the indoor and the outdoor is maintained by the outer wall 10, the ceiling 11, the foundation 8, and the ground (solid foundation or soil surface) 14. The house 1 is provided with a ventilation air conditioner 6, and the ventilation air conditioner 6 has two or more systems for blowing and controlling the conditioned air conditioned by the ventilation air conditioner 6. When the ventilation air conditioner 6 is driven, outdoor air is drawn into the ventilation air conditioner 6 as indicated by an arrow a, and the air (cooling, heating, dehumidification, ventilation) conditioned by the ventilation air conditioner 6 is supplied to one system. The air is supplied to the LDK 2 and the second floor living room 4 by a duct or the like as shown by arrows b and c. At the same time, the air conditioned by the ventilating air conditioner 6 is supplied to the other system by a duct or the like as shown by arrows f and h below the floor 7 or between the first floor and the second floor.
Supplied to In the case of this example, the water is supplied to both the under-floor 7 and the under-the-ceiling 13, but it may be either one. The air-conditioned air supplied to the underfloor 7 passes through the inside of the underfloor 7 and flows indoors through the in-wall ventilation layer as indicated by an arrow i. The conditioned air supplied to the ceiling 13 flows through the ceiling 13 to the second floor living room 4 and the like as indicated by the arrow j. In addition, the indoor air on the floor 12 is sucked into the ventilation air conditioner 5 from the corridor / wash face 3 as shown by an arrow d, and air-conditioned again to be supplied to the LDK 2, the second floor living room 4, the under floor 7, the ceiling 13 and the like, The air is exhausted outdoors as indicated by an arrow e.

As described above, the ventilation and air conditioning of the house 1 can be performed by the ventilation air conditioner 6, but since the foundation 8 is airtight, a high airtightness between the indoor and outdoor areas is maintained and thermal efficiency is maintained. Can be improved. In other words, by applying airtightness to the foundation 8, as shown by the thick line in FIG.
0, ceiling 11, foundation 8 and ground (solid foundation or earth surface) 14
It is possible to sufficiently secure airtightness between the indoor and outdoor areas by surrounding the indoor area, and to improve the thermal efficiency by eliminating heat leakage from indoors to outdoor areas. In addition, the conditioned air is supplied from the ventilation air conditioner 6 to the LDK 2 or 2.
It can be directly supplied to the floor room 4 and air-conditioned, and the air-conditioned air can be supplied to the underfloor 7 and the back of the ceiling 13 so that the underfloor 7 and the back of the ceiling 13 can also be air-conditioned. The air conditioner can be cooled and heated to provide more comfortable air conditioning. Especially during heating, comfortable heating can be achieved from the feet. In addition, the ventilation of the underfloor 7 can be performed by passing the conditioned air under the underfloor 7, and even if the airtightness of the foundation 8 is maintained, the underfloor 7 can be ventilated to prevent the accumulation of moisture in the underfloor 7. In addition, the ventilation of the ceiling 13 can be performed by passing the conditioned air through the ceiling 13, and the accumulation of moisture in the ceiling 13 can be prevented.

[0009] In the above example, the underfloor 7 and the underside 1
It is desirable that the operation mode of the system that blows out to 3 is only ventilation, dehumidification, and heating, and the cooling mode is eliminated. If the underfloor 7 and the back of the ceiling 13 are cooled by the cooling operation, dew condensation may occur on the first 12 floors, the second floor, and the first floor ceiling, and blows out to the underfloor 7 and the ceiling 13. Elimination of the cooling operation mode of the system can prevent dew condensation on the floor and ceiling.

[0010]

According to the first aspect of the present invention, in a high-density high-insulation house in which a foundation is hermetically sealed to perform planned ventilation and cooling / heating by a ventilation air conditioner, air-conditioned air conditioned by the ventilation air conditioner is used. It has two or more systems to control blowing, one or more of which are under the floor or the first floor and two
It is intended to blow out to the ceiling between the floors, such as between the floors, so that even if the floor cannot be kept airtight by applying airtightness to the base that is easily airtight, it can be used between indoors and outdoors. Air-tightness to improve thermal efficiency, and also supply air-conditioned air under the floor and above the ceiling to air-condition the floor below and above the ceiling. Air conditioning can be performed more comfortably by cooling and heating by heat transfer.Also, air-conditioned air can be ventilated under the floor to provide airtightness to the foundation, allowing under-floor ventilation. By ventilating the back, it is also possible to ventilate the ceiling and ventilate the ceiling.

[0011] The invention of claim 2 of the present invention relates to claim 1
The operation mode of the system that blows out under the floor and above the ceiling is only ventilation, dehumidification, and heating, and the cooling mode is eliminated.By eliminating the cooling mode, dew condensation on the floor and ceiling is prevented. You can do it.
