Zusammenfassung: | To improve an illuminance of a work space and improve air conditioning efficiency.SOLUTION: A radiant air conditioning duct 3 is composed of an upper box 31 and a lower box 32, and is fixed to a ceiling 50. The upper box 31 is formed from a lightweight corrugated board member with high thermal insulation. The lower box 32 is formed from a metal (aluminum) with high thermal conductivity, and its bottom surface functions as a radiant panel 34 that exchanges heat between the inside of the radiant air conditioning duct 3 and the inside of a room. The surface of the radiant panel 34 has a plurality of reflective surfaces 36 that reflects light radiated from a lighting fixture (light source) 60 in a predetermined direction and within a predetermined range. The plurality of reflective surfaces 36 reflects light radiated from the lighting fixture 60 toward the ceiling 50 (arrow B) in a predetermined direction and within a predetermined range, for example, to a work space (desk surface) approximately directly below the lighting fixture 60.SELECTED DRAWING: Figure 1
【課題】作業空間の照度を向上させるとともに、空調効率を向上させる。【解決手段】放射空調ダクト3は、上部函体31と下部函体32とから構成されており、天井50に固定されている。上部函体31は、高断熱性で、軽量の段ボール部材から形成されている。下部函体32は、熱伝導率が高い金属製(アルミニウム製)から形成されており、その底面は、放射空調ダクト3内と室内との間で熱交換を行う放射パネル34として機能する。放射パネル34の表面は、照明器具(光源)60から照射される光を、所定の方向に、かつ所定の範囲に反射させる複数の反射面36を有する。複数の反射面36は、照明器具60から天井50側に照射された光(矢印B)を、所定の方向に、かつ所定の範囲に、例えば照明器具60の略直下の作業空間(机上面)に反射する。【選択図】図1 |
