Abstract: An air-conditioning system comprising a vehicle air-conditioner which uses a target blowing-out temperature as the basis to control an air outlet temperature in a cabin and a seat air-conditioning unit which sucks recirculated air into a seat and controls at least the seat air-conditioning air flow per unit time so as to perform seat air-conditioning, wherein the air-conditioning system increases the seat air-conditioning air flow when detecting that the vehicle speed is a predetermined value or less, calculates a correction amount for the target blowing-out temperature considered neutral in warmness sense level for the increased seat air-conditioning air flow, and uses the correction amount as the basis to correct the target blowing-out temperature.

Abstract: An air conditioner includes a cooling heat exchanger configured to cool air, and a wet-state detection sensor attached to an air outlet surface of the cooling heat exchanger to detect a wet state of the air outlet surface due to condensation water. The air outlet surface of the cooling heat exchanger is tilted by an angle with respect to a horizontal direction or is perpendicular to the horizontal direction, and the wet-state detection sensor is arranged at a position in an upper half area of the air outlet surface in a direction perpendicular to the horizontal direction. Alternatively, the wet-state detection sensor is arranged at a position of the air outlet surface in a high-temperature area in which the temperature is higher than an average temperature of the air outlet surface. In this case, the high-temperature area may be positioned within the upper half area of the air outlet surface.

Abstract: An air-conditioning device for a vehicle includes a blower and an estimating portion. The blower is disposed in an air-conditioning case, and performs a dry control for a heat exchanger arranged in a passenger compartment of the vehicle by sending air. The blower uses one of power supplied from an external power source, power supplied from the battery having residual quantity equal to or larger than a predetermined quantity, or power supplied from an in-vehicle solar cell, while the vehicle is parked. The estimating portion estimates an approximate elimination of odor generated from the heat exchanger by starting the sending of air, and stops the blower based on the estimation.

Abstract: An air conditioning system includes an air conditioner for blowing conditioned air toward a compartment of a vehicle, and a dashboard having a design surface exposed to the compartment. An inner air passage extending nearly parallel to the design surface is formed in the dashboard, and a plurality of diffusion blowing openings are formed in the design surface. Thus, the condensed air is blown from the diffusion blowing openings into the compartment of the vehicle, while passing through the inner air passage. For example, cool air is blown from the diffusion blowing openings, so that the cool air can cool the dashboard while cooling the compartment of the vehicle. Moreover, because the cool air passes through the inner air passage extending nearly parallel to the design surface, the dashboard can be effectively cooled.

Abstract: The same size casing is used for interior air blowers of a combination air conditioning and heater interior unit disposed in left- and right-hand drive vehicles, respectively. A casing width is made nearly constant from a start-of-winding position to an end-of-winding position. An approximately central fan datum line which passes through a fan is offset to a suction port side with respect to a casing datum line which passes through an approximately central part of a portion of the casing parallel to a blower rotational axis. A flange portion of a motor holder is located at a position offset to one side (suction port side) along the rotational axis rather than an opposite side along the same direction in the casing. By replacement of impression cores it is possible to manufacture the casings for right- and left-hand drive vehicles, respectively.

Abstract: 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.

Abstract: An automotive air-conditioner unit which is thin and suitable for use as a rear seat unit is composed of a blower unit with a centrifugal fan and a scroll casing, heat-exchanges for cooling and heating, and conditioned air outlets, all contained in an air-conditioner case. A backward centrifugal fan having a large blade angle is used in combination with a scroll casing having a small scroll angle to obtain high fan efficiency in the compact air-conditioner unit. An outlet duct requiring a higher volume of conditioned air is positioned closer to a scroll-starting position of the scroll casing than another outlet duct requiring a less volume. An air passage in the air-conditioner case is formed along a surface perpendicular to a rotational axis of the fan to reduce a pressure loss in the passage.

Abstract: An air conditioning system for a vehicle is composed of a control unit which controls an air switching door, an element for detecting a clean-air level of the outside air and a vehicle speed sensor. The control unit controls the air-switching door to set to the outside-air mode when the clean-air level is higher than a reference level and to the inside-air mode when the clean-air level is not higher than the reference level. The control unit holds the inside-air mode until the vehicle speed becomes higher than a predetermined speed irrespective of the clean-air level.

Abstract: An air conditioning system for an automobile having an evaporator, in a refrigerating circuit, and a heater core which is located downstream from the evaporator in a duct having an inlet for introduction of air and an outlet for discharging the air into a cabin, and an air mix damper for controlling the ratio of the amount of air into the heater core and the amount of air by-passing the heater core. The degree of the opening of the air mix damper is controlled in accordance with the cooling capacity at the evaporator sensed by an after-evaporator temperature sensor so that a target value of the temperature of the air discharged into the cabin is obtained. A correction of the degree of opening of the air mix damper is done by estimating an actual temperature at the after-evaporator sensor during a transient state of the system between the ON and OFF conditions of a compressor, so that a desired setting of the air conditioning state is maintained.
