Summary:To provide technique capable of reducing heat loss due to heat exchange even when inside air and outside air are used in order to separate CO2.SOLUTION: An inside air introduction duct 52 and an inside air outlet duct 54 introduce and circulate air in an object space indoors as inside air and return the air into the object space. An outside air introduction duct 56 and an outside air outlet duct 58 introduce and circulate air outdoors as outside air and release the air outdoors. A CO2 separation element 20 separates CO2 from the inside air flowing through the inside air introduction duct 52 so as to be introduced into the outside air flowing through the outside air introduction duct 56. A first temperature adjustment unit 4a and a second temperature adjustment unit 4b adjust at least one of a temperature of the inside air and a temperature of the outside air introduced into the CO2 separation element 20. A control unit 5 performs control so that a temperature difference between the temperature of the inside air and the temperature of the outside air introduced into the CO2 separation element 20 is smaller than a temperature difference between a temperature of the air in the object space and the temperature of the outdoor air.SELECTED DRAWING: Figure 1 【課題】ＣＯ２を分離するために内気と外気とを使用する場合であっても、熱交換による温熱ロスを低減する技術を提供する。【解決手段】内気導入ダクト５２、内気吹出ダクト５４は、屋内における対象空間の空気を内気として導入して流通し、対象空間に還流させる。外気導入ダクト５６、外気吹出ダクト５８は、屋外の空気を外気として導入して流通し、屋外に放出させる。ＣＯ２分離素子２０は、内気導入ダクト５２を流通する内気からＣＯ２を分離して外気導入ダクト５６を流通する前記外気に導入する。第１温調部４ａと第２温調部４ｂは、ＣＯ２分離素子２０に導入される内気の温度と外気の温度の少なくとも１つを調節する。制御部５は、ＣＯ２分離素子２０に導入される内気の温度と外気の温度との間の温度差が、対象空間の空気の温度と、屋外の空気の温度との間の温度差よりも小さくなるように制御する。【選択図】図１
