STRUCTURE

To provide a structure which can make it difficult for heat to escape out of a room by placing it in an inoperable situation in winter while circulating heat in the room out of the room in summer.SOLUTION: An outer wall material 1 is provided with: two plate members 10; and a slope 30 configured in a circulation structure forming a storage part Res of coolant HF in one plate member 10a of the two plate members 10 to return the coolant HF condensed in the other plate member 10b to the storage part Res while the coolant HF in the storage part Res evaporated by heat with the one plate member 10a reaches the other plate member 10b. The outer wall material 1, further, is provided with latent heat storage material PCM. The latent heat storage material PCM permits the coolant to circulate in a melting condition when temperature of the one plate member 10a is equal to or higher than a predetermined temperature. Also, the latent heat storage material PCM prohibits the coolant to circulate in a solid condition when the temperature of the one plate member 10a drops lower than a specific temperature which is equal to or lower than the predetermined temperature.SELECTED DRAWING: Figure 1 【課題】夏場に室内の熱を室外へ貫流させる一方で冬場には不稼働状態として熱を室外に逃がし難くすることが可能な構造体を提供する。【解決手段】外壁材１は、２枚の板材１０と、２枚の板材１０のうちの一方の板材１０ａ側に冷媒ＨＦの貯留部Ｒｅｓを形成し、一方の板材１０ａ側の熱によって蒸発した貯留部Ｒｅｓ内の冷媒ＨＦが他方の板材１０ｂ側に到達し、他方の板材１０ｂ側において凝縮した冷媒ＨＦを再度貯留部Ｒｅｓに戻す循環構造とされたスロープ３０とを備えている。さらに、外壁材１は潜熱蓄熱材ＰＣＭを備えている。潜熱蓄熱材ＰＣＭは、一方の板材１０ａ側の温度が所定温度以上である場合に溶解状態となって冷媒循環を許容する。また、潜熱蓄熱材ＰＣＭは、一方の板材１０ａ側の温度が所定温度以下の特定温度未満である場合に固化状態となって冷媒循環を禁止する。【選択図】図１
