To provide COsupply equipment that hardly cause shutdown, and also hardly consume wasteful power.SOLUTION: COsupply equipment 1 comprises: a heat source part 10 which includes a combustor 102 and a heat exchanger 103, and in which combustion gas including COgenerated by combustion of the combustor 102 is cooled by heat exchange with water flowing in the heat exchanger 103 and from which the cooled combustion gas is discharged； a heat-radiating part 20 which includes a heat exchanger 301 in which water circulates from/to the first heat exchanger 103, and a cooling fan 302 sending cooling air to the heat exchanger 301, the heat-radiating part 20 cooling water flowing in the heat exchanger 301 by heat exchange with cooling air； an inlet temperature sensor 306 which detects the temperature of water flowing into the heat exchanger 301 as heat-radiating part inlet temperature； an atmospheric temperature sensor 307 which detects the temperature around the heat-radiating part 20 as atmospheric temperature； and a control part. The control part controls the number of revolutions of the cooling fan 302 on the basis of a temperature difference between the heat-radiating part inlet temperature and the atmospheric temperature.SELECTED DRAWING: Figure 2【課題】運転停止を招きにくく、無駄な電力消費を招きにくいＣＯ２供給装置を提供する。【解決手段】ＣＯ２供給装置１は、燃焼器１０２と熱交換器１０３とを含み、燃焼器１０２の燃焼により発生した、ＣＯ２を含む燃焼ガスが、熱交換器１０３を流れる水との間の熱交換により冷却されて排出される熱源機１０と、熱交換器１０３との間で水が循環する熱交換器３０１と、熱交換器３０１に冷却風を送る冷却ファン３０２とを含み、熱交換器３０１を流れる水を冷却風との熱交換によって冷却する放熱機２０と、熱交換器３０１に流入する水の温度を放熱機入口温度として検出する入口温度センサ３０６と、放熱機２０の周囲の温度を雰囲気温度として検出する雰囲気温度センサ３０７と、制御部と、を備える。制御部は、放熱機入口温度と雰囲気温度との温度差に基づいて、冷却ファン３０２の回転数を制御する。【選択図】図２
