To form a recirculation port 20 in a wall part without having a double wall structure as a whole, to facilitate construction and simplify a structure, in a temperature-controlled air recirculation device A for air-conditioning that sends temperature-controlled air from an indoor space S1 into an underfloor space S2 to heat a floor part 10, etc., and then recirculates it to the indoor space S1 through the recirculation port 20.SOLUTION: A lower end part of a partition wall 7 is provided with an in-wall ventilation unit 23 that sections a communication space S communicating with an indoor space S1 and an underfloor space S2. The unit 23 comprises: a box 24 installed at the lower end part of the partition wall 7 in a state of being open to the indoor side, and having the communication space S inside; a baseboard receiver 28 arranged on the indoor side of the box 24, and formed with a baseboard receiver opening 35 as a return port 20; and a circulation baseboard 41 fixed to the baseboard receiver 28. The box 24 is installed so that a floor part 10 is positioned in an intermediate part in a height direction of the internal communication space S. The baseboard receiver 28 is arranged so as to cover a communication part of the communication space S with the indoor space S1.SELECTED DRAWING: Figure 2 【課題】室内空間Ｓ１からの温調空気を床下空間Ｓ２に送り込んで床部１０を加熱等した後に還流口２０にて室内空間Ｓ１に還流させる冷暖房用温調空気還流装置Ａにおいて、壁部にその全体を二重壁構造にせずに還流口２０を形成して、施工の容易化や構造の簡略化を図る。【解決手段】間仕切り壁７内の下端部に、室内空間Ｓ１及び床下空間Ｓ２と連通する連通空間Ｓを区画する壁内通気ユニット２３を設ける。このユニット２３は、間仕切り壁７内下端部に室内側に開口した状態で設置されかつ内部に連通空間Ｓを有するボックス２４と、ボックス２４の室内側に配置され、還流口２０としての巾木受け開口３５が形成された巾木受け２８と、巾木受け２８に固定される還流用巾木４１とを備える。ボックス２４は、内部の連通空間Ｓの高さ方向中間部に床部１０が位置するように設置され、巾木受け２８は、連通空間Ｓの室内空間Ｓ１との連通部を覆うように配置されている。【選択図】図２
