To reduce noise of an engine.SOLUTION: A refrigerator unit 15 comprises: a casing 30; a compressor 41 arranged in the casing 30, and for compressing a refrigerant; a driving source 50 arranged in the casing 30, and for driving the compressor 41; a partition wall 62 for partitioning a space in the casing 30 into a driving source housing part S22 in which the driving source 50 is housed, and a compressor housing part S23 in which the compressor 41 is housed; a fan 63 for generating wind flowing toward the outside of the casing 30 via the compressor housing part S23 from the driving source housing part S22; and a throttle part 70 formed by the partition wall 62, and for narrowing a flow passage cross sectional area for the wind flowing to the compressor housing part S23 from the driving source housing part S22. An outlet opening part 39B for allowing communication between the compressor housing part S23 and the outside is formed in the casing 30.SELECTED DRAWING: Figure 2
【課題】エンジンの騒音を低減する。【解決手段】冷凍機ユニット15は、ケーシング30と、ケーシング30内に配置されて冷媒を圧縮する圧縮機41と、ケーシング30の内部に配置されて圧縮機41を駆動する駆動源50と、ケーシング30内の空間を駆動源50が収容される駆動源収容部S22と圧縮機41が収容される圧縮機収容部S23とに区画する区画壁62と、駆動源収容部S22から圧縮機収容部S23を経てケーシング30の外部に向かって流れる風を発生させるファン63と、区画壁62によって形成され、駆動源収容部S22から圧縮機収容部S23に流れる前記風の流路断面積を狭める絞り部70と、を備え、ケーシング30には、圧縮機収容部S23と外部とを連通させる出口開口部39Bが形成されている。【選択図】図2
