PROBLEM TO BE SOLVED: To achieve large heat recovery even when a heat exchanger is disposed at a complicated place.SOLUTION: An air blowing device includes: a blower; and a heat exchanger having a first air duct 151 which is disposed perpendicularly upward of the blower and flows air to a first outlet 151b from a first inlet 151a and a second air duct 152 which flows air to a second outlet 152b from a second inlet 152a and performs heat exchange between air flowing into the first air duct and air flowing into the second air duct. The first inlet directs to a direction nearer to a horizontal direction than to a vertical direction and is disposed facing an air suction port. The first outlet directs to a direction nearer to the vertical direction than to a horizontal direction and is disposed facing to the suction part of the blower. The first air duct includes an air duct curved part which gradually changes its direction from a first direction inward from the outside of the first inlet along a direction where the first inlet directs to a second direction to which the first outlet directs, between the first inlet and the first outlet.SELECTED DRAWING: Figure 5
【課題】込み入った場所に熱交換器を配置する場合でも、大きな熱の回収を実現できる。【解決手段】送風機と、送風機の鉛直上方に配置され、第1導入口151aから第1導出口151bへ空気を流す第1風路151と、第2導入口152aから第2導出口152bへ空気を流す第2風路152とを有し、第1風路に流れる空気と第2風路に流れる空気との間で熱交換を行う熱交換器と、を備える。第1導入口が、鉛直方向より水平方向に近い方向を向き、空気取込口に対向して配置され、第1導出口が、水平方向より鉛直方向に近い方向を向き、送風機の吸入部に対向して配置され、第1風路は、第1導入口と第1導出口との間で、第1導入口が向く方向に沿って第1導入口の外から内に向かう第1方向から、第1導出口が向く第2方向へ、徐々に向きを変える風路曲がり部を有する。【選択図】図5
