PROBLEM TO BE SOLVED: To provide a heat storage system enabling both of cooling and heating, and capable of reducing a use weight of a latent heat storage material in storing heat beyond season, and provide an installation method for the latent heat storage material.SOLUTION: A heat storage system 1 includes: an indoor space IDS; a heat storage space HSS adjacent to the indoor space IDS, and where a latent heat storage material H is installed, the latent heat storage material having a melting point or freezing point within a range of 5-30°C; and a natural ventilation device NV configured to control introduction/cutoff of outside air to the heat storage space HSS. Heat resistance between the heat storage space HSS and the outside air is made larger than heat resistance between the heat storage space HSS and the indoor space IDS.SELECTED DRAWING: Figure 1 【課題】冷暖房の双方が可能であって、シーズンを超えて蓄熱する際の潜熱蓄熱材の使用重量の軽減を図ることが可能な蓄熱システム及びその潜熱蓄熱材の設置方法を提供する。【解決手段】蓄熱システム１は、室内空間ＩＤＳと、室内空間ＩＤＳに隣接すると共に摂氏５度以上摂氏３０度以下の範囲に融点又は凝固点をもつ潜熱蓄熱材Ｈが設置された蓄熱空間ＨＳＳと、蓄熱空間ＨＳＳへの外気の導入及び遮断を制御する自然換気装置ＮＶと、を備え、蓄熱空間ＨＳＳと外気との熱抵抗が、蓄熱空間ＨＳＳと室内空間ＩＤＳとの熱抵抗よりも大きくされている。【選択図】図１
