Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of varying the thermal resistance of a composite insulation panel.

Traditionally, foamed plastic insulation materials such as foamed polyurethane, foamed polystyrene, foamed polyethylene, and foamed polypropylene, foamed mortar, and foamed glass have been used in buildings to achieve goals such as energy saving, improved comfort, prevention of condensation, and protection of building structures. , foamed inorganic insulation materials such as foamed silica boards,
Various types of insulation materials (hereinafter referred to as insulation materials), such as wood-based insulation materials such as wood wool cement boards, wood cement boards, and wood chip cement boards, and inorganic fiber-based insulation materials such as glass wool and rock wool, are used for the interior and exterior walls of buildings.・Used for ceilings, under floors, rooftops, and roofs, and various composite materials of insulation materials and plates such as Keikal board, flexible board, plywood, gypsum board, aluminum, and steel board are also used.

However, when using insulation materials in buildings, conventional methods involve fixing or fixing insulation materials or composite insulation panels made of insulation materials inside walls, on wall surfaces, on ceilings, under floors, etc. Therefore, it is not easy to make the heat insulating material perform movements such as movement, rotation, compression, and expansion, and therefore, it is impossible to make the thermal resistance variable. In addition, some methods have been used to change the thermal resistance by impregnating the insulation material with water, but it is impossible to achieve a desired thermal resistance.
Additionally, there is a risk of water leakage, making it impractical.

By the way, when using insulation materials in buildings, it is not just a matter of high thermal resistance; it is necessary to use thermal insulation materials when the amount of heat generated inside the building is large, when the indoor temperature is higher than the outside air temperature in the summer, or when the solar radiation increases in the winter. When the external surface temperature of a building is higher than the indoor temperature due to energy consumption, lower thermal resistance of the outer wall or roof of the building will save energy and improve comfort.

For example, during a sunny day in the summer, the outside temperature is 30°C to 40°C, and at the equivalent outside temperature taking into account solar radiation,
The temperature will be between 50℃ and 70℃, which is higher than the comfortable indoor temperature.
Because the outside temperature (equivalent outside temperature) is always higher,
The greater the thermal resistance of a building envelope, the more energy it will save and the more comfortable it will be. However, at night in summer, the outside air temperature (equivalent outside air temperature) is often lower than the indoor temperature. Easier release, improved comfort, and energy savings.

In addition, the outside temperature at night in winter is generally lower than the indoor temperature, so the thermal resistance of the building envelope should be increased to prevent heat leakage. In such cases, the outside temperature becomes considerably high and heat flows from the outside to the indoor side, so it is advantageous for the thermal resistance of the building envelope to be small.

The present invention relates to a method for setting the thermal resistance of a composite insulation panel to an optimal value by mechanically moving, regenerating, compressing, and expanding the insulation material, which is a constituent layer of the composite panel. Movement (deformation) operations such as movement, rotation, compression, and expansion of the insulation material may be performed manually, by using a motor, plunger, solenoid, etc., or by other power sources. be. In addition, by sensing outside air temperature, outside wall surface temperature, indoor temperature, indoor surface temperature, heat flow, etc. using a single or multiple sensors, we can turn on indicator lights and automatically control motors, etc. to achieve optimal thermal resistance. may be automatically set or recognized.

Inorganic molded plates such as flexible plates and calcium plates, and metal plates such as aluminum plates, steel plates, and stainless steel plates are thought to be suitable as components for composite insulation panels, but other plate-shaped molded products can also be used. . Also, although foamed plastic would be suitable as an insulating material, any other insulating material could be used.

Next, an actual variable thermal resistance mechanism based on the present invention is shown in FIGS. 1 and 2, but the present invention can be implemented using other mechanisms as long as the thermal resistance of the composite panel can be varied. good.
