摘要： 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.

摘要： 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.

摘要： 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.
