Abstract | To suppress noise caused by rotation of a propeller fan.SOLUTION: A heat source unit (3) of a refrigeration device (1) includes a box-shaped casing (50) having a suction port (53) on a back face and one of side faces, and a blowout port (52) on a front face, a partitioning plate (51) disposed in the casing (50) in a manner of being opposed to one side face of the casing (50) and forming an air passage (A) for communicating the suction port (53) and the blowout port (52), a heat exchanger (60) having a first part (61) along the back face of the casing (50) and a second part (62) along one of the side faces of the casing (50), and a propeller fan (70) for blowing out the air toward the blowout port (52) of the casing (50). A first distance S1 as a shortest distance between an outer peripheral circle (V) of the propeller fan (70) and the second part (62) of the heat exchanger (60) and a second distance S2 as a shortest distance between the outer peripheral circle (V) of the propeller fan (70) and the partitioning plate (51) satisfy a relationship of 6≤S1/S2.SELECTED DRAWING: Figure 2
【課題】プロペラファンの回転によって生じる騒音を抑制する。【解決手段】冷凍装置(1)の熱源ユニット(3)は、背面及び一方の側面に吸込口(53)が形成され、前面に吹出口(52)が形成された箱状のケーシング(50)と、ケーシング(50)内にケーシング(50)の一方の側面と向かい合うように設けられ、吸込口(53)と吹出口(52)とを連通させる空気通路(A)を形成する仕切板(51)と、ケーシング(50)の背面に沿う第1部分(61)と、上記ケーシング(50)の一方の側面に沿う第2部分(62)とを有する熱交換器(60)と、ケーシング(50)の吹出口(52)に向かって空気を吹き出すプロペラファン(70)とを備える。そして、プロペラファン(70)の外周円(V)と熱交換器(60)の第2部分(62)との最短距離である第1距離S1と、プロペラファン(70)の外周円(V)と仕切板(51)との最短距離である第2距離S2とが、6≦S1/S2の関係を満たす。【選択図】図2 |
