Regarding things.

Technical background of the invention In order to achieve high thermal insulation of a building, a building has been developed in which a heat insulating material is stretched so as to comprehensively surround each room in the building.

In order to perform cooling or heating in such a building, conventionally, the cooling or heating device is used.
There is a demand for cooling or heating using natural energy without using these devices or in combination with these devices.

However, in a building in which the surroundings are comprehensively surrounded by a heat insulating material, there are disadvantages that ventilation in the building is likely to be insufficient and natural energy is difficult to use.

The purpose of the present invention is to eliminate the disadvantages of the above-described conventional technology, and while the surroundings are comprehensively surrounded by a heat insulating material, it has excellent breathability in the building, especially in summer, when natural energy is used. It is an object of the present invention to provide a building having a regenerative heat storage block capable of cooling the inside of the building by utilizing.

SUMMARY OF THE INVENTION In order to achieve such an object, a building having a heat storage block according to the present invention has an outer wall so that an inner ventilation layer communicating with an attic space is formed at least on the indoor side of the building. Insulation material is stretched in the surface direction on the indoor side of the roofing material and roofing material, the underfloor ventilation port that can introduce outside air into the underfloor space in the underfloor part, and the air in the attic space can be led to the outside in the underfloor part An underfloor ventilation opening, an underfloor ventilation opening that allows the air in the attic space to be led out to the outside is formed in the underfloor area, and a building in which opening and closing dampers are provided in both of these ventilation openings. A cool storage heat block or a cool storage heat member is attached to the underfloor space.

A fan for circulating air between the inner ventilation layer and the underfloor space is preferably attached to the underfloor portion or the underfloor space.

According to the building having the cold storage heat block or the cold storage heat member according to the present invention, when the outside air temperature is high, for example, in the summer daytime, all the ventilation openings are closed and the cooling device for each room is installed. When the fan is activated and the underfloor fan is activated, the cold heat stored at night in the cold storage block or cold storage member installed in the underfloor part or underfloor circulates through the inner ventilation layer, attic space and underfloor space by the fan. It exchanges heat with the generated air to lower the temperature around the room and assist the cooling effect of the cooling device in each room.

In addition, when the outside air temperature is relatively low, such as during summer nights, all ventilation openings are opened and the fan is started to take the outside air into the underfloor space from the underfloor ventilation opening and then pass it through the cold storage heat block. It is guided to the inner ventilation layer through the holes or the gaps between the cool heat storage members, and discharged to the outside of the building through the attic space and the ventilation holes under the ridge. With this, the hot air in the attic is discharged to the outside, and the relatively low temperature outside air is guided to each room and the inner ventilation layer,
Cool the building using natural energy. At the same time, cold heat at night is stored in the cold heat storage block or the cold heat storage member, and this can be used for cooling in the daytime.

In addition, since the cold storage heat block and the cold storage heat member can store not only cold heat but warm heat, it is possible to perform heating using this warm heat.

Describing based on FIG. 3, when the control starts in step 100, the process goes to step 101, and in step 101,
An outside air sensor provided outside the building 2 for detecting the outside air temperature calculates an average outside air temperature for one day or for a predetermined time, and sets the value as Tm.

Next, at step 102, this average outside air temperature Tm is the predetermined temperature T
o Determine if it is greater than or equal to. If so (Tm ≧ To), it is determined that the season is summer or a day corresponding thereto, and the process proceeds to step 103. Step 103 to step
The control up to 107 is the control in the day when the season is summer or its equivalent.

In step 103, it is determined whether or not the cooler switch in the cooling device 12 is turned on. If the cooler is turned on, the process proceeds to step 104. The case of going to step 104 is the case where the cooler switch is turned on, and corresponds to the daytime of summer when the outside temperature is high. In this case, as shown in FIG. 1, the opening / closing dampers 28, 24 are controlled so that all the ventilation openings 13, 14, 18 are closed, and the underfloor fan 3

As a result, the hot air in the attic 20 is discharged to the outside, the relatively low temperature outside air is guided to each room 10 and the inside ventilation layers 7, 7a, and the interior of the building is cooled by using natural energy. Along with that, the cold heat storage block 30 is provided with cold heat at night, and this can be used for cooling in the daytime. Regarding the ventilation port 13,
It is not necessary to open it.

Next, in step 105, it is detected whether or not a control switch for performing such control is included, and if the switch is not included, the control ends. If the switch is still on, the process returns to step 101 to continue the control.

If it is determined in step 102 that Tm <To, it can be determined that the season is winter or a day corresponding to winter. In such a case, the process proceeds to step 109.

In step 109, close all vents 13, 14, and 18,
Control the open / close dampers 24, 28, and go to step 105. As a result, the opening / closing dampers 24 and 28 remain closed, and the airtightness in the building is secured. The ventilation port 13 does not necessarily have to be closed.

It should be noted that the present invention is not limited to the above-described embodiments, but can be modified in various ways.

For example, as shown in FIG. 4, the underfloor space 16 and the outside air are configured to communicate with each other through a communication pipe 44 arranged in the ground, without providing an underfloor ventilation port in the outer peripheral foundation body 42. Is also good. The underfloor end of the communication pipe 44 is open to the underfloor space 16, and the outside air end is open to the outside air. It is preferable to provide an opening / closing damper in the middle of the communication pipe 44 buried underground to control the opening / closing damper. By introducing the outside air into the underfloor space 16 through the communication pipe 44 arranged in the ground, it is more convenient because the underground cold heat or warm heat can be effectively used.

In addition, as shown in FIG.
A cold storage heat block 52 having a through hole 50 communicating with each other may be arranged. In this example, an underfloor fan
34 is attached to one outlet of the through hole 50,
The air passing through the inside 50 can circulate in the underfloor space 16 and the inside ventilation layer.

In each of the above embodiments, the underfloor fan 34 does not necessarily have to be mounted.
