DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an energy saving panel system.

[0002]

2. Description of the Related Art Conventionally, as a structure of a surrounding wall for improving the heating efficiency of a building, a mat made of inorganic fibers or the like is provided between a surrounding wall material and an interior wall material of a surrounding wall through a ventilation windproof sheet or the like. A heat insulating wall with a heat insulating material interposed is known (for example, Japanese Utility Model Application Laid-Open Nos. 56-174613 and 58-29716). Furthermore, a heat storage tank containing a latent heat storage agent is provided in the basement of the building as a system for saving energy for cooling and heating the inside of the building composed of the above-mentioned peripheral walls, and a solar water heater or the like is linked to the storage tank. There is known a heat utilization system that stores heat inside and radiates heat for heating at night (for example,
No. 62-163644).

[0003]

In the above, when the surrounding wall of the building has a heat insulating wall structure, the heating efficiency can be improved as compared with a wall having no heat insulating material. However, this effect is mainly achieved by the heat insulating material. Because of the efficiency, if the difference between the outside air temperature and the indoor air temperature becomes large, it is impossible to prevent the indoor air temperature from being reduced, and there is a problem that some kind of heating device is required. On the other hand, if the above-mentioned heat-insulating wall and the above-mentioned heat utilization system are used in combination, it is convenient to save energy during nighttime heating when the temperature difference between the inside and outside is large, but it is necessary to provide a separate heat storage tank under the building, which requires equipment. There was a major problem.

Furthermore, since a solar water heater is used as a heat source for heat storage, heat storage can hardly be expected when the day is cloudy or rainy, and the effect of energy saving must rely solely on insulating walls. As a result, there has been a problem that effective utilization of heat energy cannot be sufficiently achieved. Further, the above-mentioned device is limited only to the case of heating, and a separate cooling device is required for cooling in summer, and there is a problem that a large-scale heat storage device is completely wasted during this period.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a heat storage member using the surrounding wall itself of a building as a heat storage member so that heat can be stored at an arbitrary time zone. An object of the present invention is to provide an energy-saving panel system that can maintain a temperature and can be used not only for heating but also for cooling.

[0006]

That is, in the energy-saving panel system of the present invention, a wall material 2D in which a surrounding wall 1A of a building 1 is interposed with an exterior wall material 2A, a heat insulating material 2B, and a latent heat storage agent 2C is provided. The interior wall materials 2E are laminated in this order, and the laminated wall materials 2 are laminated in this order. The entrances and exits 4A and 4B of the air path 3 for exchanging heat with the interposed latent heat storage agent 2C are provided on the indoor side. A heating device 5 for storing heat in the latent heat storage agent 2C that is operable at an arbitrary time zone is provided in the laminated wall material 2 to intermittently release and store heat. In the invention, the surrounding wall 1A of the building 1 is composed of a laminated wall material 2 formed by laminating an exterior wall material 2A, a heat insulating material 2B, a wall material 2D interposed with a latent heat storage agent 2C, and an interior wall material 2E in this order. Entrance and exit of the air path 3 for performing heat exchange with the inserted latent heat storage agent 2C A and 4B are provided on the indoor side, and a heating device 5 operable at an arbitrary time zone for storing heat in the interposed latent heat storage agent 2C is provided in the laminated wall material 2, and the latent heat storage agent 2C Air path 3 for heat exchange
In addition to the air inlets and outlets 4A and 4B on the indoor side, air inlets and outlets 4C and 4D through which outdoor air flows in and out are provided, and the air inlets and outlets 4C and 4D are provided with a blower fan 9 and a damper 10. Is what you do.

[0007]

According to the system of the present invention, a peripheral wall 1A of a building 1 is provided.
Is composed of the laminated wall material 2 in which the exterior wall material 2A, the heat insulating material 2B, the wall material 2D interposed with the latent heat storage agent 2C and the interior wall material 2E are laminated in this order, so that the heat is not stored in the latent heat storage agent 2C. Even so, the heat insulating material 2B improves the indoor and outdoor heat insulating efficiency. Further, when the heat is stored in the latent heat storage agent 2C, the heat is prevented from being wastefully radiated by the heat insulating material 2B,
Heat is efficiently stored in combination with the heat storage efficiency of the latent heat storage agent 2C, and indoor air is circulated through the air path 3 that exchanges heat with the latent heat storage agent 2C in accordance with the room temperature to radiate heat indoors. Even if the outside temperature is significantly lower than the indoor temperature,
Indoor comfortable temperature can be easily maintained.

[0008] Further, since the heat storage in the latent heat storage material 2C is performed by the heating device 5 which can be operated at any time, it is possible to store the heat at a low cost by using, for example, midnight electric power, thereby saving energy. Can be In addition, as the heating device 5 for heat storage, in addition to the heater using the midnight power described above, various types such as a heat pump that collects heat contained in domestic wastewater, a solar water heater, a heating heater using a solar cell, and geothermal, are used. It is also possible to make it possible to use one having the highest heat collection efficiency selectively.

Further, in another aspect of the present invention, air inlets and outlets 4C and 4D through which outdoor air flows in and out of the indoor air inlets and outlets 4A and 4B are provided in an air passage 3 for performing heat exchange with the latent heat storage agent 2C. In the summer, cool air at night is circulated from the air inlets and outlets 4C and 4D to cool the latent heat storage agent 2C, close the damper 10 during the day, and exchange heat with the latent heat storage agent 2C to exchange the air with the air inlets and outlets 4A and 4B. The cold air can be taken into the room from inside.
