Abstract: An air conditioning unit includes an air conditioning casing formed with an inlet and an outlet. The air conditioning casing allows air to flow in the air conditioning casing from the inlet to the outlet. The conditioning unit also includes an evaporator arranged in the air conditioning casing and having substantially a U-shape and a U-Shaped outer air flow path provided on an outer side of the U-shaped evaporator in the air conditioning casing. An inner air flow path is provided on an inner side of the U-shaped evaporator in the air conditioning casing and a heater core is arranged in the air conditioning casing.

Abstract: An air conditioning unit for a vehicle has an air conditioning casing having flow paths therein, an evaporator arranged in the air conditioning casing and substantially having a U-shape, an outer flow path provided on the outer side of the U-shaped evaporator on the upstream or downstream side of an air flow of the U-shaped evaporator, an inner flow path provided on the inner side of the U-shaped evaporator on the downstream or upstream side of the air flow of the U-shaped evaporator, and a heater core arranged on the downstream side of the air flow of the U-shaped evaporator.

Abstract: To provide a cockpit module structure for a vehicle where large foot space and a secure and stable supported state can be secured, the body of an air conditioning unit inside which heat exchangers and opening and closing doors are installed is penetrated by a steering member.

Abstract: A centrifugal multiblade fan comprises a plurality of curved blades which are circularly arranged about a common rotation axis at evenly spaced intervals defining a curved air flow passage between every neighboring blades. Each curved blade has concave front and convex rear surfaces which extend longitudinally in parallel with the rotation axis. A lower annular end plate is provided for putting thereon lower ends of the circularly arranged blades. A radially outside part of each curved blade has a radius of curvature which is greater than that of a radially inside part of the blade. A slit extends longitudinally parallel with the rotation axis at a radially inside portion of each blade.
