PROBLEM TO BE SOLVED: To reconcile vertical down-sizing of a fan unit 15 provided in a pack case, and efficiency securing of a fan 42.SOLUTION: A fan unit 15 has an electric motor 41 arranged in such a posture that a rotating shaft 41a is perpendicular to the bottom surface, a substantially cylindrical fan 42, and a case 43. The case 43 has an outlet side duct 49, and an inlet side duct 50, and an inlet 18 including an evaporator 19 is located higher than the fan 42. The ceiling wall 53 of the inlet side duct 50 has an inclined surface part 53a, a plane part 53b, and an arc surface part 53c connecting the two above the rotating shaft 41a of the electric motor 41. The plane part 53b is located lower than the inlet 18. Consequently, degradation of efficiency is less, while down-sizing the vertical dimension.SELECTED DRAWING: Figure 6 |
