Abstract: Disclosed is a blowing unit of an air conditioner for a vehicle, having a two-layer structure and capable of effectively suppressing a flow of air flowing backward around a scroll bell mouth. In a blowing unit of an air conditioner for a vehicle, having a scroll case in which a first flow path and a second flow path are partitioned so as to separate inside and outdoor air to be sucked, the scroll case has a partition wall for separating a suction part of the first flow path and a suction part of the second flow path, and the partition wall has an air backflow prevention part for preventing air flowing into one of the first flow path or the second flow path from flowing backward into the other.

Abstract: A vehicular air conditioning system includes: a refrigerant circulation line including first and second evaporators through which refrigerant can flow in a cooling mode, and first and second expansion valves configured to depressurize and expand the refrigerant introduced into each of the first and second evaporators; and refrigerant flow control part provided in front of the first evaporator and the first expansion valve and configured to control refrigerant flow. The first evaporator is used for cooling rear seat region of a passenger room and the refrigerant flow control part is configured to supply and block the refrigerant with respect to the first evaporator and the first expansion valve and is configured to block the refrigerant when the cooling governed by the first evaporator is controlled in a turn-off mode and supply the refrigerant to the first evaporator and the first expansion valve depending on the on/off condition of the cooling governed by the second evaporator.

Abstract: A vehicular heat management system includes a refrigerant circulation line including a compressor, a high pressure side heat exchanger, a heat pump mode expansion valve, an outdoor heat exchanger, and a plurality of low pressure side heat exchangers installed parallel to each other. The refrigerant circulation line further includes a refrigerant pipe having an increased diameter portion formed by increasing the diameter of a specific refrigerant pipe portion among a plurality of refrigerant pipe portions affecting a refrigerant pressure in the refrigerant pipe portions on the intake and discharge sides of the compressor so that the specific refrigerant pipe portion has a larger diameter than other refrigerant pipe portions.

Abstract: The present invention relates to an air conditioner for a vehicle which can block air introduced through a gap between an evaporator and an air-conditioning case and prevent condensate from overflowing toward a temperature adjusting door when condensate exceeding a drainable amount is generated. The air conditioner for a vehicle includes: an air-conditioning case having an air passageway therein; an evaporator disposed in the air passageway of the air-conditioning case; a drain hole disposed at the downstream side of the evaporator in an air flow direction to discharge condensate to the outside; a first baffle protruding upwardly from the bottom surface of the air-conditioning case; and a fourth baffle protruding upwardly from the bottom surface of the air-conditioning case and formed downstream of the first baffle in the air flow direction, wherein the first baffle and the fourth baffle are formed in such a way that at least some of them are overlapped with each other in the width direction to be formed doubly in the air flow direction.
