Abstract
An air conditioning apparatus with a film door for switching outlets to respective positions of a cabin. The film shaped door has a value of flexural rigidity per width of 10 mm in a range between 1.1 and 2.5 (.mu.Nm.sup.2). An amount of leaked air of 0.00175 (m.sup.2 /s) or less and an operating force of a step motor for driving the film shaped door of 50 (mN.times.m) or less are obtained.
Claims6
An air conditioning apparatus for a compartment to be air conditioned in an automobile, comprising:
- a casing defining therein a passageway for an air flow to be introduced into the compartment;
- a flexible film member cooperating with the passageway for controlling the flow of the air;
- a first shaft rotatably supported by the casing, while one of the ends of the flexible film member is connected to the first shaft, so that the member is wound on the first shaft;
- a second shaft rotatably supported by the casing, while the other end of the flexible film member is connected to the second shaft, so that the member is wound on the second shaft, and;
- an electric motor for generating a rotating movement applied to at least one of the first and second shafts so that the flexible film member is moved for causing a degree of a cooperation between the film member and the passageway to be varied;
- the flexible film member having a value of a flexural rigidity per width of 10 mm in a range between 1.1 and 2.5 (.mu.Nm.sup.2).
