An air conditioning unit for a vehicle includes: an air conditioning case defining an in-case passage in which air flows to a vehicle interior; a cooler arranged in the air conditioning case and configured to cool the air flowing in the in-case passage; a blower that includes a blower motor and an impeller configured to be rotated by the blower motor and generate an air flow in the in-case passage; and a cooling passage portion defining a motor cooling passage in which air flows to cool the blower motor. The blower is arranged downstream of the cooler with respect to the air flow in the air conditioning case. The motor cooling passage includes a passage inlet located downstream of the impeller with respect to the air flow in the in-case passage, and a passage outlet located upstream of the impeller with respect to the air flow in the in-case passage.

The disclosure relates to the technical field of vehicles, and particularly provides a vehicle, a method and system for drying an evaporator of a vehicle air conditioner, and a storage medium, aiming to solve the problems of low efficiency and poor effects of an existing method for drying an evaporator of a vehicle air conditioner. In the method for drying an evaporator of a vehicle air conditioner provided according to the disclosure, the vehicle air conditioner comprises an evaporator core, an air duct for circulating air is constructed in an air conditioner box, and a fan, the evaporator core and a heating core are arranged in the air duct, the method comprises: closing the air duct after cooling of the vehicle air conditioner is stopped; operating the heating core and the fan, so as to generate, by means of the heating core and the fan, hot air which can circulate in the air duct, wherein during circulation, the hot air carries away condensed water precipitated on a surface of the evaporator core for conversion into hot and humid air; and directly venting the hot and humid air from the air duct to exterior environment, so that the evaporator core is dried. The method provided according to the disclosure can implement the drying of the evaporator with high-efficiency and low energy consumption.

An air blower device of an air-conditioning system for a vehicle including: a blower case including a duct part having an indoor air inlet and an outdoor air inlet, an air blowing part connected with an inlet of an air-conditioning case and a connection part for connecting the duct part with the air blowing part, the connection part having an insertion part of which the certain area is hollowed; an indoor and outdoor air converting door disposed inside the duct part of the blower case to open and close the indoor air inlet and the outdoor air inlet; an air blower is disposed inside the air blowing part of the blower case to forcedly blow air; an electric dust collector located at the connection part through the insertion part of the blower case; and a cover for opening and closing the insertion part of the blower case.

An air-conditioning system of a motor vehicle having refrigerant circulation and coolant circulation. Refrigerant circulation comprises a compressor, a refrigerant-coolant heat exchanger operable as condenser/gas cooler for heat transfer between the refrigerant and the coolant, a first expansion element and a first refrigerant-air heat exchanger for conditioning the inflowing air for the passenger compartment. Coolant circulation is developed with a conveying device, a first coolant-air heat exchanger for heating the inflowing air for the passenger compartment, a second coolant-air heat exchanger and the refrigerant-coolant heat exchanger. Refrigerant circulation also includes a second refrigerant-air heat exchanger, operable exclusively as evaporator. Upstream of the second refrigerant-air heat exchanger in the direction of flow of the refrigerant, a second expansion element is disposed. The second expansion element and the second refrigerant-air heat exchanger are disposed within a first flow path. A method for operating the air-conditioning system.

A smart multi-modal vehicular air filtration management system including a first filter element and a second filter element disposed in a fresh air housing, wherein the fresh air housing has an inlet and an outlet. Additionally, a third filter element is provided which is disposed in a cabin housing, the cabin housing having one or more inlet. A fluid channel arranged between the fresh air and cabin housing. Finally, a diverter is included which is disposed near an outlet of the fresh air housing, wherein the diverter is configured to cause air to flow through the fresh air housing selectively through one or both of the first filter element and the second filter element.

A blower unit includes a casing defining a first passage and a second passage, a first internal-external air switching member, a second internal-external air switching member, and a partition defining an opening. During a two-layer internal/external air mode, the first internal-external air switching member opens an external air inlet and closes an internal air inlet and the second internal-external air switching member closes the external air inlet and opens the internal inlet, so that the external air is directly introduced into the first passage through the external air inlet and the external air in the second passage is introduced into the first passage through the opening of the partition and the internal air is directly introduced into the second passage through the internal air inlet and the internal air in the first passage is introduced into the second passage through the opening of the partition.
