In an air passage switching device, a flexible film moves to traverse an air passage of an air duct, thereby switching and controlling a communication state of the air passage. A thickness t of the film, a glass transition temperature Tg thereof and a radius of curvature r thereof are set so that a relationship expressed by a formula of t≦(0.00578×Tg0.448×r0.333) is satisfied and a bending stiffness of the film is set equal to or higher than 1 &mgr;N·m2. Accordingly, the film can be restricted from being buckling-deformed and from being damaged. As a result, an air leakage amount from a clearance between the film and the air passage due to the deformation can be effectively restricted.

A ventilation controlling apparatus using a slide door made of a flexible film member to solve imperfect slide action attributable to film member rigidity degradation on the fringe of an aperture. The slide door is movably disposed inside a casing which forms an air passage, and the slide door is composed of the flexible film member provided with an air-circulation aperture. Ventilation of the air passage is controlled by varying an area of blending or connection between the aperture and the air passage in accordance with movement of the slide door. A rigid support member is fitted around the fringe of the aperture on the film member, thereby enhancing rigidity of the aperture fringe.

In an air passage opening/closing device for an air conditioner, a slide door for opening and closing an opening portion of a case includes a flexible film member having a free top end that moves forward by pushing force in a door moving direction. A movement of the film member is guided along a guide ditch. The guide ditch is provided so that the film member is approached to a seal surface in a direction perpendicular to a door moving direction, in comparison with the other seal surface on a peripheral portion of the opening portion. For example, a pushing member for pushing the film member to the seal surface in the direction perpendicular to the door moving direction can be provided. Accordingly, air leakage due to a bending habit of the film member can be restricted.

An air conditioning apparatus for a vehicle has a unit case, a heat exchanger for generating a heated air, a bypass passage through which a bypass air flows while bypassing the heat exchanger, and a baffle member having first passages and second passages. The unit case has openings for introducing a conditioned air into a passenger compartment. The openings are aligned in an alignment direction across a width of the unit case. The first passages and second passages are alternately arranged in the alignment direction. One of the bypass air and the heated air has an uneven distribution of a flow speed in the alignment direction at a position upstream of the baffle member, and flows in the first passages. Widths of the first passages are varied according to the distribution of the flow speed.

An automotive air conditioner comprises an offset blower for blowing an air, an evaporator is centrally disposed within a dashboard and receives the air from below, and a heater approximately horizontally disposed above the evaporator. The evaporator inclines downward along the direction of the air flow. A plurality of condensed water guide plates are provided under the evaporator so as to allow a condensed water smoothly flow on the surface of each guide plate and is discharged from the evaporator through a condensed water drain pipe.

An interior of an air conditioning case is partitioned into a first air passage extending from an inside air suction port to a foot opening portion and a second air passage extending from an outside air suction port is disposed at a side of the first air passage to detect a temperature of air blown out from the evaporator disposed in the first air passage and the second air passage. An operation of the compressor for supplying the refrigerant to the evaporator is intermitted by comparing the temperature detected by the temperature sensor and the set temperature set in advance, and the set temperature is changed to be higher according to an increase in the temperature of outside air. In this way, it is possible to prevent the frosting of the evaporator in winter season, when the inside air is introduced into the first air passage and the outside air is introduced into the second air passage.

In an air passage opening/closing device for a vehicle air conditioner, a driving member is disposed to apply driving force for a reciprocating movement of a film member to at least one position of the film member, and a guide member is provided in an air-conditioning case to guide the reciprocating movement of the film member. The film member has a flexible performance to move in a bend path, and has a rigidity to be moved along the guide member when pushing force from the driving member is applied to the film member. Thus, the air passage opening/closing device using the film member has a simple structure without a film-winding mechanism.

According to the present invention, an air conditioning apparatus include a case partitioned into a first air passage and a second air passage by partition plates (16-19), a heat exchanger such as a heater core. The heater exchanger is sandwiched between the partition plates. Further, the heat exchanger is formed by laminating tubes and a fin while the fin is disposed in each main air passage formed between tube walls of the tubes. Each end of the partition plates is opposite to each end of the tubes so that the partition plates are parallel to the tubes. In this way, airflows which respectively have passed from the air first and second passages pass through the heat exchanger without being mixed with each other therein. As a result, the separation characteristics of airflows can be improved.

A blower unit includes a centrifugal fan, a fan casing forming a scroll-shaped air passage and accommodating the centrifugal fan, and a partition wall for partitioning an interior of the fan casing into first and second air passages in which different kinds of airs flow, respectively, in the axial direction. The partition wall is molded integrally to the fan casing so as to extend linearly from the inner wall surface of the fan casing toward a radial inside of the fan. The fan casing includes two divided cases having a divided face in the axial direction. In this way, the number of divided cases can be as well as the number of steps of assembling the fan casing can be reduced so that the work efficiency for assembling the fan casing is improved.
