The nonwoven fibers are fixed to the nonwoven mat at one end and configured to be electrostatically charged by the nonwoven mat. An electrical charge generator is electrically connected to the nonwoven mat and configured to electrostatically charge the fiber nonwoven, so that the electrostatically charged nonwoven fibers straighten toward a center of the air-conditioning line body in such a way that they close an open flow cross section of the air-conditioning line body.

A thermal management system may include a first cooling circuit cooling PE parts and including a first radiator, a first coolant line circulating a coolant between the first radiator and the PE parts, and a first electric water pump circulating the coolant along the first coolant line, a heat pump system including a compressor compressing a refrigerant, an internal condenser performing a heat exchange between the compressed refrigerant and air supplied inside a vehicle, a refrigerant line circulating the refrigerant between the compressor and the internal condenser, and a heat exchanger for the heat exchange between the coolant and the refrigerant, a flow increase bypass line between the first coolant lines on the entrance and exit sides of the PE parts, and a coolant control valve provided at location where the flow increase bypass line is branched in the first coolant line and controlling a flow direction of the coolant.

The present invention relates to an air conditioner for a vehicle, which includes an air-conditioning case (200), and at least one door (100) mounted to be opened and closed at a predetermined position, wherein the door (100) is formed integrally with an arm pivot (140), and the arm pivot (140) includes a pin part, and ribs formed integrally with both sides of the pin part to reinforce rigidity of the pin part and offset noise. The air conditioner further includes distortion preventing parts formed on a rotary shaft to be dented and to be crossed to each other, thereby reducing a transformation rate of the door and securing accuracy of the pin part.

An air conditioning system for a vehicle may include a refrigerant line through which a refrigerant circulates and an evaporator and a condenser are connected to each other; and a first core and a second core for indoor air conditioning, wherein the first core includes a first inlet and a first outlet through which a coolant passing through the evaporator is introduced and discharged, respectively, the second core includes a second inlet and a second outlet through which a coolant passing through the condenser is introduced and discharged, respectively, and the first core and the second core are connected to each other through a connection line, and the connection line is provided with a first valve selectively connecting the first core and the second core through the connection line.

Provided is a damper of an air vent for a vehicle, in which an operating member and a pad member are assembled with a structure in which a coupling protrusion of the operating member is inserted into a coupling hole of the pad member. As dimensions of the damper become accurate, a gap is not formed, thereby preventing air leakage. Moreover, due to no need for overlap of the pad member, the operating force of the damper is reduced and becomes uniform, and friction noise of the pad member in operation is prevented. Furthermore, an assembly method is simple, facilitating automation and expecting productivity improvement.
