Problems solved by technology

[0022] In short, in a building insulation panel (insulation panel) for the purpose of connecting a single structure formed by combining a conventional vacuum insulation material and a heat storage material (or heat insulation material) in a planar shape, in order to In order to realize a vacuum insulation material that can reduce thermal bridges, the current situation is that the cost increases or the development of materials takes time. Therefore, as a result, the suppression measures for thermal bridges have not achieved low cost and high efficiency, and there is a problem of lack of versatility.

Abstract

Provided is a heat-insulating panel for use in buildings that has strong heat-insulating effects and can store heat when individual heat-insulating panels, which combine a vacuum-insulation material and a heat-storing material, are connected in a planar manner. Said heat-insulation panel (101A) has a basic structure obtained by covering the entirety of a plate-shaped vacuum-insulation material (102) with a heat-insulation material (104), and is provided with a latent heat storage material (103) that is arranged in a substantially frame like shape extending from one main surface of the vacuum-insulation material (102), wrapping around the sidewall thereof, and connecting to the other main surface thereof, so as to cover the entire peripheral edge of the vacuum-insulation material (102). The latent heat storage material (103) is provided to mitigate heat bridging that results from heat leakage between high temperature and low temperature parts in the vacuum-insulation material (102) under usage conditions that undergo changes in temperature, by means of latent heat. The heat-insulation material (104) is arranged in a manner such that the heat-insulation material covers the entire surface of the latent heat storage material (103) and the entire exposed surface of the vacuum-insulation material (102).

Description

technical field [0001] The present invention relates to a thermal insulation panel for buildings, which is suitable for use in combination with an air-conditioning and hot water supply system, and is a single structure with excellent thermal insulation performance and a simple structure for alleviating the heat leakage of a vacuum thermal insulation material by the latent heat of a latent heat storage material. The above-mentioned air-conditioning and hot-water supply system includes refrigeration and air-conditioning circuits using new refrigerants with low global warming potential (GWP), and is designed for new-century houses with high ecological (environmental response) effects. Background technique [0002] In recent years, countermeasures for suppressing global warming have become urgent, and energy saving has been demanded even in residential environments. In order to realize these measures, it is desired to reduce energy consumption by improving the thermal insulation...
