To provide a duct of deformable section capable of controlling increase of static pressure while improving workability in a narrow space, and to provide a radiation cooling/heating system utilizing the duct of deformable section.
This duct 50 of deformable section comprises a main body 52 formed by rounding a rectangular sheet member 51, and cylindrically shaping it in a state that opposite edge portions 51a, 51b are overlapped, and a fastening member 55 for fastening an overlapped portion 52w of the edge portions 51a, 51b, the rectangular sheet member 51 is composed of a member keeping elastic deformation when it is deformed to a ratio D1/D2 of 1.1 where a distance between two points free from external force EF is D1, and a distance between two points when the external force EF is added to the main body 52 is D2. The radiation cooling/heating system performs cooling/heating by radiation heat of a sectional face by conveying the air of which a temperature is adjusted, to a back side of the sectional face of a cooling/heating chamber by the duct 50 of deformable section and spraying the air to the sectional face.
