-
FIGS. 1A and 1B are cross sectional views showing a structure of a floor of a building concerning the first embodiment of the present invention.FIG. 1A shows a heating mode operated in a winter season.FIG. 1B shows a cooling mode operated in a summer season.FIG. 2 is a plan view showing the structure of the floor shown inFIG. 1 . - As shown in
FIGS. 1A and 1B , the structure of the floor of the building concerning the first embodiment is composed of afirst board 11, asecond board 12, athird board 13, afourth board 14,heat storage members 20, and apeltier unit 30. Thepeltier unit 30 includespeltier elements 15, a blowingfan 31, a blowingfan 32, amotor 33, and amotor 34. - The
first board 11 is a board arranged between a foundation (not illustrated) and ajoist 16. Below thefirst board 11 is an under-floor space. The present specification is described assuming that the under-floor space is classified as outdoor. - The
second board 12 is arranged above (indoor side of) thefirst board 11 while facing thefirst board 11. Thesecond board 12 has openings so as to engage thepeltier elements 15. Thepeltier elements 15 are arranged so that heat is transferred in a thickness direction (vertical direction) of thesecond board 12 by being connected to a DC power source. - The
third board 13 is arranged above (indoor side of) thesecond board 12 while facing thesecond board 12. - The
fourth board 14 is arranged above (indoor side of) thethird board 13 while facing thethird board 13. Thefourth board 14 can be, for example, a board forming a floor. - The
heat storage members 20 are arranged between thethird board 13 and thefourth board 14. Theheat storage members 20 can be a latent heat storage member. The latent heat storage member is, for example, a member of absorbing and releasing a large amount of heat while maintaining a constant temperature using a phase change between a solid phase and a liquid phase. For example, when the latent heat storage member having a phase change temperature of about 20° C. is used, even if an outside temperature is changed from 25° C. to 15° C., it takes a long time before the latent heat storage member is cooled to below 20° C. Therefore, the room temperature can be maintained at 20° C. for a long time. Alternately, theheat storage members 20 can be a sensible heat storage member. As the sensible heat storage member, ceramics can be used. The ceramics preferably include at least either one of mullite, cordierite, zirconia, SiC, zeolite, and Shirasu. Alternately, theheat storage members 20 can be a chemical heat storage member. - The
peltier element 15 transfers heat from one surface to the other surface by being connected to a DC power source (not illustrated). The one surface is a heat absorbing surface (low temperature), while the other side is a heat radiating surface (high temperature). If the polarity of the voltage applied to thepeltier element 15 by the DC power source is inverted, the heat absorbing surface and the heat radiating surface are exchanged.FIG. 1A shows a case where heating is performed in the winter season by arranging the heat radiating surface on the upper side.FIG. 1B shows a case where cooling is performed in the summer season by arranging the heat absorbing surface on the upper side. Thepeltier element 15 can have a plurality of pleats (not illustrated) on the heat radiating surface and the heat absorbing surface. - The blowing
fan 31, as a first air flow generating device, is arranged between thefirst board 11 and thesecond board 12 and closely to thepeltier element 15. The blowingfan 32, as a first air flow generating device, is arranged between thesecond board 12 and thethird board 13 and closely to thepeltier element 15. The blowingfan 31 is connected to themotor 33, and the blowingfan 32 is connected to themotor 34. Since themotors fans fans peltier element 15. By the air flow, heat absorption of the heat absorbing surface of thepeltier element 15 is enhanced and heat radiation of the heat radiating surface is enhanced. - In the first embodiment, as shown in
FIG. 2 , the blowingfans peltier element 15 when viewed thesecond board 12 in a plane view while sandwiching thepeltier element 15. In addition, the blowingfans second board 12. Thus, the blowingfans peltier element 15. It is preferred that the blowingfan 31 is larger and has higher blowing capability than the blowingfan 32. - When the upper side is specified to be the heat radiating surface as shown in
FIG. 1A , a space between thesecond board 12 and thethird board 13 is heated by thepeltier element 15. Then, the heat is transferred to theheat storage members 20 by heat conduction through thethird board 13 and the heat is stored in theheat storage members 20. The heat stored in theheat storage members 20 is released to an above-floor space while taking a long time, thus achieving heating of the above-floor space. The heating of the first embodiment is achieved mainly by heating effect of radiation from theheat storage members 20 to the above-floor space, rather than heating effect of the air blow of the heated air. By using the heating effect of the radiation, the heating, which is less harmful to human body and friendly to human body, can be achieved. In addition, the heating using thepeltier element 15 can obtain good heating effect with small energy because the heat absorbed by the heat absorbing surface is used in addition to Joule heat generated by a current. - In
FIG. 1A , a space between thefirst board 11 and thesecond board 12 is cooled by thepeltier element 15. A temperature sensor (not illustrated) can be provided in the space between thefirst board 11 and thesecond board 12. In addition, another temperature sensor (not illustrated) can be provided in the under-floor space. When a temperature of the space between thefirst board 11 and thesecond board 12 becomes lower than a temperature of the under-floor space, a ventilating opening (not illustrated) provided on thefirst board 11 can be opened so as to ventilate the space between thefirst board 11 and thesecond board 12. A blowingfan 35 can be provided so as to forcibly exhaust air from the space between thefirst board 11 and thesecond board 12. The blowingfan 35 can be a fan for helping to circulate air in the space between thefirst board 11 and thesecond board 12. - The space between the
first board 11 and thesecond board 12 is larger than the space between thesecond board 12 and thethird board 13. Thus, the heat can be efficiently transferred from the space between thefirst board 11 and thesecond board 12 to thepeltier element 15 and vice versa. - A temperature sensor (not illustrated) can be provided in the space between the
second board 12 and thethird board 13. In addition, another temperature sensor (not illustrated) can be provided in the above-floor space. When a temperature of the space between thesecond board 12 and thethird board 13 becomes high enough compared to a temperature of the above-floor space, an air supply opening (not illustrated) can be opened so as to supply hot air from the space between thesecond board 12 and thethird board 13 to the above-floor space. - When the upper side is specified to be the heat absorbing surface as shown in
FIG. 1B , the space between thesecond board 12 and thethird board 13 is cooled by thepeltier element 15. Then, the heat stored in theheat storage members 20 is released to the space between thesecond board 12 and thethird board 13 by heat conduction through thethird board 13. Theheat storage members 20 are cooled, thus achieving cooling of the above-floor space. The cooling of the first embodiment is achieved mainly by cooling effect caused by small radiation from theheat storage members 20 to the above-floor space, rather than cooling effect of the air blow of the cooled air. The cooling effect caused by small radiation has the following meanings. Although all objects emit radiation heat according to a temperature and an emissivity of the object, when the radiation heat emitted from the object to human body is small, cooling effect can be obtained for the human body. For example, even when the temperature is same between the inside and the outside of a tunnel, the inside of the tunnel is felt cooler than the outside. The cooling effect caused by small radiation is based on the same principle as this example. By using the cooling effect caused by small radiation, the cooling, which is less harmful to human body and friendly to human body, can be achieved. In addition, the cooling using thepeltier element 15 can obtain good cooling effect with small energy because a room is felt cooler even when the temperature is not changed. - In
FIG. 1B , the space between thefirst board 11 and thesecond board 12 is heated by thepeltier element 15. When a temperature of the space between thefirst board 11 and thesecond board 12 becomes higher than a temperature of the under-floor space, a ventilating opening (not illustrated) provided on thefirst board 11 can be opened and the blowingfan 35 is operated if needed so as to ventilate the space between thefirst board 11 and thesecond board 12. - As described above, the space between the
first board 11 and thesecond board 12 is larger than the space between thesecond board 12 and thethird board 13. Thus, the heat can be efficiently transferred from the space between thefirst board 11 and thesecond board 12 to thepeltier element 15 and vice versa. - In the
peltier element 15, an amount of the heat released from the heat radiating surface is approximately 1.5 times more than an amount of the heat absorbed by the heat absorbing surface. Therefore, during a cooling operation in the summer season, it is necessary to release the heat efficiently from the heat radiating surface. In the present embodiment, the space between thefirst board 11 and thesecond board 12 is 1.2 times to 2.5 times more than the space between thesecond board 12 and thethird board 13, and is preferably 1.5 times. Furthermore, the blowingfan 31 is larger and has higher blowing capability than the blowingfan 32. Thus, the heat can be efficiently released from the heat radiating surface during the cooling operation in the summer season. Thefirst board 11 can be removed so that a space below thesecond board 12 is the under-floor space. - When a temperature of the space between the
second board 12 and thethird board 13 becomes low enough compared to a temperature of the above-floor space, an air supply opening (not illustrated) can be opened so as to supply cool air from the space between thesecond board 12 and thethird board 13 to the above-floor space. - In the first embodiment, the
second board 12 is preferred to be a board having high heat insulating performance. In addition, thethird board 13 is preferred to be a board having high thermal conductivity. For example, metal material is suitable. Thus, the amount of heat absorbed in thepeltier element 15 and released from thepeltier element 15 can be efficiently transferred to theheat storage members 20. Although thefourth board 14 is preferred to be a board having high thermal conductivity, a thermal conductivity performance of the board can be adjusted while considering the feeling of users when cooling or heating. Thefirst board 11 is also preferred to be a board having high thermal conductivity. Thus, an unnecessary heat generated when cooling is easily released to the under-floor or a cool heat generated when heating is easily released to the under-floor. On the other hand, since the heat insulating performance is also required so that inside the room is not affected by a fluctuation of outside temperature, a thermal conductivity performance of the board can be adjusted. - In addition, the
heat storage members 20 are held in contact with thethird board 13, which is arranged on the indoor side and has high thermal conductivity, and thepeltier element 15 is held by thesecond board 12, which is arranged on an outdoor side of thethird board 13 facing thethird board 13 and has high heat insulating performance. Consequently, the heat is transferred from thepeltier element 15 to thethird board 13 through the space. - Since the space is interposed, heating and cooling by the
peltier element 15 is not locally concentrated. Furthermore, since heating or cooling is performed while theheat storage members 20 store the heat, heating and cooling is felt to be gentle. -
FIGS. 3A and 3B show a structure of a wall concerning the second embodiment of the present invention.FIG. 3A is a cross-sectional view andFIG. 3B is a front view. In the second embodiment,heat storage members 22 are provided on the space between thesecond board 12 and thethird board 13, and theheat storage members 22 are attached to thethird board 13. The fourth board 14 (shown inFIG. 1 ) can be omitted. The heat storage members 20 (shown inFIG. 1 ) provided on the space between thethird board 13 and thefourth board 14 can be omitted. Aninterior finish material 13 a is applied to a surface of the indoor side of thethird board 13. In addition, an exterior finishing material 11 a is provided on a surface of an outdoor side of thefirst board 11 so as to face thefirst board 11 while being separated in a certain distance from thefirst board 11. An insulating material (not illustrated) can be provided on a space between thefirst board 11 and the exterior finishing material 11 a. Apillar 19 can be provided on a space between thefirst board 11 and thethird board 13. - The
heat storage members 22 can be formed by kneading a chemical heat storage member, which is enclosed in capsules having an approximately same size as pebbles, with a mixture of diatomite, plaster and Shirasu. Note that the mixture of diatomite, plaster and Shirasu is the sensible heat storage member. Shirasu is a powdery substance created from magma before the magma becomes rock. Shirasu can be taken from a stratum in throughout the southern part of Kyushu region. The mixture of diatomite, plaster and Shirasu is also excellent in a function of adjusting humidity and a function of absorbing harmful gas and odor. For example, theheat storage members 22 can be constructed by attachingforms 22 a on thethird board 13, daubing the mixture of diatomite, plaster and Shirasu inside theforms 22 a, and drying the daubed mixture. In addition, the mixture of diatomite, plaster and Shirasu can be used for theinterior finish material 13 a so that theinterior finish material 13 a has a function of storing heat, a function of adjusting humidity, and a function of absorbing harmful gas and odor. - Although the
heat storage members 22 are attached to thethird board 13 inFIG. 3A andFIG. 3B , theheat storage members 22 can be provided on the space between thesecond board 12 and thethird board 13 and theheat storage members 22 can be attached to thesecond board 12. Furthermore, theheat storage members 22 can be in contact with both thesecond board 12 and thethird board 13. - In other respects, the second embodiment is same as the floor structure indicated in the first embodiment.
- In the second embodiment, the
second board 12 is preferred to be a board having high heat insulating performance. In addition, thethird board 13 is preferred to be a board having high thermal conductivity. For example, metal material is suitable. Thus, the amount of heat absorbed in thepeltier element 15 and released from thepeltier element 15 can be efficiently transferred to theheat storage members 22. In addition, the amount of heat can be suitably transferred between theheat storage members 22 and thethird board 13 when theheat storage member 22 heats and cools the indoor. Thefirst board 11 is also preferred to be a board having high thermal conductivity. Thus, an unnecessary heat generated when cooling is easily released to the outside or a cool heat generated when heating is easily released to the outside. In the present embodiment, since the exterior finishing material 11 a is further provided on the outdoor side of thefirst board 11, the necessity for preventing the fluctuation of outside temperature from affecting inside the room is low. -
FIGS. 4A and 4B show a structure of a wall concerning the third embodiment of the present invention.FIG. 4A is a cross-sectional view andFIG. 4B is a front view. In the third embodiment, aninterior finish material 13 b is provided on a surface of the indoor side of thethird board 13 so as to face thethird board 13 while being separated in a certain distance from thethird board 13. In addition, anexterior finishing material 11 b is provided on a surface of the outdoor side of thefirst board 11 so as to face thefirst board 11 while being separated in a certain distance from thefirst board 11. - An
opening 13 x is formed on thethird board 13. By theopening 13 x, hot air can be supplied to a space between thethird board 13 and theinterior finish material 13 b during the heating operation, and cool air can be supplied thereto during the cooling operation. The hot air or the cool air supplied to the space between thethird board 13 and theinterior finish material 13 b can be supplied to an indoor space through another opening (not illustrated) provided on theinterior finish material 13 b. Even if the hot air or the cool air is supplied to the indoor space, an air flow is reduced by theinterior finish material 13 b and therefore bad influences on the human body caused by the air flow is suppressed. -
Heat storage members second board 12 and thethird board 13. Theheat storage members heat storage member 23 can have a phase transition temperature of approximately 28° C., which is a recommended preset temperature during the cooling operation in the summer season. In addition, theheat storage member 24 can have a phase transition temperature of approximately 20° C., which is a recommended preset temperature during the heating operation in the winter season. In addition, theheat storage member 25 can have a phase transition temperature of approximately 24° C. so as to be used both in the summer season and the winter season. For example, if the latent heat storage member containing paraffin is used, a desired phase transition temperature can be obtained by selecting the number of carbons. - In other words, the
heat storage members - Furthermore, the
heat storage member 23 for the summer season is preferred to be arranged on an upper side, and theheat storage member 24 is preferred to be arranged on a lower side. Theheat storage member 25 for both use can be arranged between theheat storage member 23 and theheat storage member 24, or arranged both between a plurality of theheat storage members 23 and between a plurality of theheat storage members 24. - Openings are provided both on the
first board 11 and theexterior finishing material 11 b. Avent pipe 11 c is provided between thefirst board 11 and theexterior finishing material 11 b so as to connect the opening of thefirst board 11 with the opening of theexterior finishing material 11 b. By thevent pipe 11 c, the space between thefirst board 11 and thesecond board 12 can be ventilated. - Insulating
materials second board 12. Thus, a temperature difference between both surfaces of thesecond board 12 generated by the function of thepeltier element 15 can be prevented from being lost caused by heat transfer in thesecond board 12. - Alternately, the materials indicated by the
symbols second board 12, the bad influences of the dew condensation can be suppressed. The dehumidification sheets can be attached to thefirst board 11 and thethird board 13. - Alternately, the materials indicated by the
symbols heat storage member 24 and theheat storage member 25 can be reflected to the indoor side. The heat reflecting sheets are preferably arranged on thesecond board 12 on a surface of the side of thethird board 13, as indicated by thesymbol 12 b. The heat reflecting sheets are preferably a sheet containing thin film layer of metal such as aluminum. - In other respects, the third embodiment can be same as the second embodiment.
- In the third embodiment, since the insulating
materials second board 12, the preferable heat insulating performance of thesecond board 12 does not have to be considered. In addition, thethird board 13 is preferred to be a board having high thermal conductivity. Thus, the amount of heat absorbed in thepeltier element 15 and released from thepeltier element 15 can be efficiently transferred to theheat storage members 22. In addition, the amount of heat can be suitably transferred between theheat storage members 22 and thethird board 13 when theheat storage member 22 heats and cools the indoor. Furthermore, the hot air and the cool air can be supplied toward theinterior finish material 13 b through theopening 13 x. - Although the
first board 11 is preferred to be a board having high thermal conductivity, an unnecessary heat generated when cooling can be released to the outside or a cool heat generated when heating can be released to the outside. In the present embodiment, since theexterior finishing material 11 b is further provided on the outdoor side of thefirst board 11, the necessity for preventing the fluctuation of outside temperature from affecting inside the room is low. -
FIG. 5 is a cross-sectional view showing a structure of a wall concerning the fourth embodiment of the present invention. In the fourth embodiment, aventilator 40 is provided. Openings are formed on each of theexterior finishing material 11 b, thefirst board 11, thesecond board 12, thethird board 13, and theinterior finish material 13 b. Theventilator 40 includes asleeve tube 42. Thesleeve tube 42 connects the openings from the opening of theexterior finishing material 11 b to the opening of theinterior finish material 13 b. Thesleeve tube 42 can be a tube connecting the openings from the opening of thefirst board 11 to the opening of thesecond board 12 or to the opening of thethird board 13. - A blowing
fan 37 and a porousheat storage member 38 are provided inside thesleeve tube 42. The porousheat storage member 38 has many holes penetrating between the indoor side and the outdoor side. The porousheat storage member 38 is, for example, a structure of having many hexagonal holes (i.e. honeycomb-shaped). The porousheat storage member 38 explained above is formed by ceramics, for example. - The blowing
fan 37 is connected to amotor 39. Themotor 39 can rotate the blowingfan 37 while switching a rotation direction by a predetermined time interval between a first rotation direction and a second rotation direction which is opposite to the first rotation direction. The predetermined time is approximately one minute to three minutes, for example. - In the
ventilator 40, if themotor 39 rotates the blowingfan 37 in the first rotation direction for one minute to three minutes, the air is exhausted from the indoor to the outdoor through thesleeve tube 42. At that time, in the heating operation, a part of the heat of the air passing through the porousheat storage member 38 is stored in the porousheat storage member 38. Then, when themotor 39 rotates the blowingfan 37 in the second direction for one minute to three minutes, the air is supplied from the outdoor to the indoor through thesleeve tube 42. At that time, the air passing through the porousheat storage member 38 is heated by the heat stored in the porousheat storage member 38. By repeating such operations, the indoor air can be ventilated while heat exchange is performed. In the cooling operation, although a direction of transferring the heat is opposite, the indoor air can be ventilated while heat exchange is performed in the same way. -
Baffle plates 36 are provided both on inside thesleeve tube 42 and inside thevent pipe 11 c. Thebaffle plates 36 have a function of preventing the structure inside the wall from being damaged by a gust of wind blew on the outside. - Openings are provided both on the
third board 13 and theinterior finish material 13 b. Avent pipe 13 c is provided between thethird board 13 and theinterior finish material 13 b so as to connect the opening of thethird board 13 with the opening of theinterior finish material 13 b. By thevent pipe 13 c, hot air can be supplied to the indoor during the heating operation, and cool air can be supplied to the indoor during the cooling operation. - In the fourth embodiment, although the explanation is based on a case where the air is ventilated from the indoor air or the air between the
second board 12 and thethird board 13 to the outdoor air and vice versa while the heat exchange is performed, the air can be ventilated between indoors having different temperatures. For example, by attaching theventilator 40 to a wall or a door partitioning between a living room and a passage, the air can be ventilated between the indoor air or the air between the living room and the passage while the heat exchange is performed. - In other respects, the fourth embodiment can be same as the third embodiment. Although only the
heat storage member 23 is shown between thesecond board 12 and thethird board 13 inFIG. 5 , theheat storage members second board 12 and thethird board 13 as explained in the third embodiment. - Furthermore, as the
heat storage members heat storage member 38. In this case, the holes are preferably penetrating in a thickness direction of thesecond board 12. If theheat storages members peltier element 15 and theheat storages members -
FIG. 6 is a cross-sectional view showing a variation example ofFIG. 5 . In the variation example shown inFIG. 6 , in thesleeve tube 42, theventilator 40 can have a blowingfan 37 a and amotor 39 a arranged on the outdoor side of the porousheat storage member 38, in addition to the blowingfan 37 and themotor 39 arranged on the indoor side of the porousheat storage member 38. If the blowingfan 37 a and themotor 39 a are provided in addition to the blowingfan 37 and themotor 39, the air can be smoothly supplied and exhausted even when strong wind is blew on the outside. Furthermore, the blowingfan 37 a and the motor can be provided inside thevent pipe 11 c. If the blowingfan 37 a and the motor are provided, the air can be smoothly supplied and exhausted even when strong wind is blew on the outside. - The fourth embodiment shown in
FIG. 5 can be used as a structure of the wall of a building of about four floors or less. The variation example shown inFIG. 6 can be used as a structure of the wall of a building of about five floors or more. - In the fourth embodiment, materials of the
first board 11, thesecond board 12 and thethird board 13 can be selected from almost the same point of view as the third embodiment.
