PROBLEM TO BE SOLVED: To curb an increase in a temperature of foundation concrete with high temperature equipment installed thereon.SOLUTION: A cooling system comprises: a storage section 55 which stores a gas turbine 53 and a generator 54 driven by the gas turbine 53; a ventilation mechanism 56 which ventilates an inside of the storage section; and a cooling unit 58 which is installed between a silencer (high temperature equipment) 57, placed on foundation concrete 52 outside the storage section 55, heated by waste heat of the gas turbine 53 and the foundation concrete 52, and has a passage section 62 penetrating the cooling unit 58 to communicate an inside of the storage section 55 with an outside thereof. Air outside of the storage section 55 is introduced into the passage section 62 of the cooling unit 58 due to negative pressure generated by the ventilation mechanism 56.SELECTED DRAWING: Figure 2 【課題】高温機器が設置される基礎コンクリートの温度上昇を抑制すること。【解決手段】ガスタービン５３およびガスタービン５３により稼働される発電機５４が格納される格納部５５と、格納部内の換気を行う換気機構５６と、格納部５５の外部の基礎コンクリート５２上に設置されてガスタービン５３の排熱により加熱される消音器（高温機器）５７と基礎コンクリート５２との間に配置されて格納部５５の内部と外部とを連通する通路部６２が貫通して設けられる冷却部５８と、を備え、換気機構５６の負圧により冷却部５８の通路部６２に格納部５５の外部の空気が導入される。【選択図】図２
