Abstract: An air-conditioning unit for a vehicle has a case, a blower, a cooling heat exchanger and a heating heat exchanger. The cooling heat exchanger is located upstream of the blower inside the case. The heating heat exchanger is located downstream of the blower inside the case. The ventilation passage includes a before-heating passage extending from an air discharge port of the blower toward an air inlet of the heating heat exchanger. The before-heating passage includes, as a part of the before-heating passage, a flow-changing path that is curved to change a flow direction of the air discharged from the blower.

Abstract: The present disclosure simplifies the H-bridge circuit of the direct current motor for driving the damper (door) that switches the air passages in the indoor unit of an air conditioning device. The control device for an air conditioner that takes in inside or outside air and conditions the air inside an air conditioning unit using an evaporator and a heater core is provided with: a first actuator and a second actuator that drive the multiple dampers installed inside the air conditioning unit for switching the air passages; and three half-bridge circuits that control the first actuator and the second actuator sharing one of the half-bridge circuits. Of the multiple dampers, the first actuator is connected to the inside/outside air switching damper. Of the multiple dampers, the second actuator is connected to at least one air mix damper.

Abstract: An air conditioner for performing air-conditioning of an interior of a vehicle cabin includes a casing, an evaporator, a blower, a controller, and a cooling passage. The casing defines a ventilation passage through which air flows from an air introduction port toward an air outlet. The evaporator cools the air flowing through the ventilation passage. The blower is disposed on a downstream side with respect to the evaporator in the ventilation passage and generates an airflow in the ventilation passage. The controller controls an output from the blower. The cooling passage causes a position located on a downstream side with respect to the blower in the ventilation passage to communicate with a position located on an upstream side with respect to the evaporator in the ventilation passage. A controller is installed in the cooling passage.

Abstract: An inner guide plate has an inner guide plate surface that guides air. An outer guide plate has an outer guide plate surface that guides the air toward a discharge port of the fan. In each of predetermined cross sections perpendicular to a rotation axis of the fan, a reference line is a line connecting the rotation axis and an outer guide end of the outer guide surface that is a radially inner end. In each of the predetermined cross sections, a guide line is a line connecting the rotation axis and an inner guide end of the inner guide surface that is a radially outer end. In each of the predetermined cross sections, a phase difference angle is an angle between the guide line and the reference line in a rotation direction of the fan. The phase difference angles of the predetermined cross sections are different from each other.

Abstract: An air conditioning device for a vehicle has an air-conditioning case, a heater core, a first air mix door, a second air mix door, and an actuator. The air-conditioning case therein has a first air passage and a second air passage. The first air mix door and the second air mix door are arranged in the first air passage and the second air passage respectively, and adjust a ratio between a flow rate of air passing through the heater core and a flow rate of air bypassing the heater core by an opening/closing operation. The actuator interlocks the opening/closing operations of the first air mix door and the second air mix door such that opening degrees of the first air mix door and the second air mix door are different from each other.

Abstract: In a vehicular air conditioning unit, an air conditioning case includes a space forming portion that forms a drainage space which is partitioned from an air passage. The space forming portion includes a drainage portion that discharges water from inside the air conditioning case to outside of the air conditioning case. Further, the space forming portion includes an upstream side communication portion that communicates the drainage space to an upstream side space on an air flow upstream side of the blower in the air passage. Further, the space forming portion includes a downstream side communication portion that communicates the drainage space to a downstream side space on the air flow downstream side of the blower in the air passage.

Abstract: An air conditioning device includes a casing that provides multiple air passages, a blower fan that suctions an air from the multiple air passages and blows out the air in the casing, a suction side partitioning member that is disposed on a suction side of the blower fan in the casing and separates air flows from the multiple air passages from each other, and a blowing side partitioning member that is disposed on a blowing side of the blower fan in the casing and separates the air flows from the multiple air passages from each other. The suction side partitioning member and the blowing side partitioning member are disposed so that a relative position of the blowing side partitioning member to the suction side partitioning member is deviated in a rotation direction of the blower fan.

Abstract: A vehicular air conditioning device includes an air conditioning case having first, second case introduction ports and first, second case discharge ports, and a fan. The first, second case discharge ports are offset upward and downward in an up-down direction relative to a rotation axis, respectively. A first inner guide surface of an inner guide plate is located on the one side of a second inner guide surface in the left-right direction. Air introduced through the first case introduction port is guided by the first inner guide surface to be drawn from a first passage into the fan, the air being blown upward to flow through the first case discharge port. Air introduced through the second case introduction port is guided by the second inner guide surface to be drawn from a second passage into the fan, the air being blown upward to flow through the second case discharge port.

Abstract: A vehicle air-conditioning apparatus includes a casing that defines an air passage through which an air flows, and a blower that has a blower fan generating an airflow in the air passage. The vehicle air-conditioning apparatus includes an air-conditioning device that is provided in the air passage, and an air introduction member that introduces an air from a vehicle compartment. The vehicle air-conditioning apparatus further includes an aspirator that is located outside the casing and takes in the air flowing through the air passage as a first air, the aspirator drawing the air from the vehicle compartment as a second air through the air introduction member by using a flow of the first air. A cooling target mounted in the vehicle is cooled by a flow of the air drawn from the vehicle compartment by the aspirator through the air introduction member.
