An inlet port of the inlet tank is opposite to, or generally opposite to, an interface between the first zone and the second zone. A first outlet tank is at the outlet end of the core opposite to the first zone. A first outlet port of the first outlet tank is at an outer end of the first outlet tank. A second outlet tank is at the outlet end of the core opposite to the second zone. A second outlet port of the second outlet tank is at an outer end of the second outlet tank.

A dual-layer flow blower unit for a vehicle air-conditioner is disclosed. The blower unit has a scroll shape so as to be blown to each of a pair of an upper blower duct and a lower blower duct, and includes a pair of an upper blower case and a lower blower case which are vertically partitioned by a partition plate. The blower unit comprises a drainage case coupled to a lower part of the lower blower case and having a drainage duct formed so as to incline downward along a longitudinal direction of the lower blower duct. The blower unit includes a blower motor cooling unit that cools a blower motor by branching a part of an air blown from the lower blower duct, flowing it into an inside of a cooling chamber, and then circulating it inside a motor case.

The present invention relates to an air conditioner for a vehicle, which can remarkably improve resistance against an air flow in an air passageway, thereby enhancing efficiency. The air conditioner for a vehicle includes: a case having an air inlet, an air outlet, and an air passageway formed therein; a blower unit for blowing air to the air inlet; and a cooling means and a heating means disposed in the air passageway of the case in an air flow direction in order, wherein the air outlet of the case includes a floor outlet and vent outlets, the floor outlet and the vent outlets are arranged below the heating means in a height direction, and the floor outlet is arranged within a range of the width of the heating means.

An air-conditioning includes a blower, a unit casing, an upstream partition, and a fan partition. The blower includes a centrifugal fan and a fan casing. The unit casing defines an upstream passage at a position upstream of the blower. The upstream partition is fixed to the unit casing to divide the upstream passage into a first upstream passage through which a first gas flows and a second upstream passage through which a second gas flows. The fan partition is fixed to the fan casing to divide an inner space of the fan into a first fan passage through which the first gas flows and a second fan passage through which the second gas flows. The unit casing defines an opening and includes a cover that closes the opening. The opening has an opening area such that the blower is removable from the unit casing through the opening.

Provided is a vehicular air conditioner including: an air-conditioning case that has an upper passage and a lower passage which are partitioned by an upper and lower partition plate therebetween; a heating unit that is disposed over the upper passage and the lower passage; an upper passage partition plate that is disposed downstream of the heating unit of the upper passage and forms a guide passage that guides a portion of air, which has passed the heating unit, toward an upper and lower connection opening that connects the upper passage and the lower passage; and a guide passage opening/closing unit that closes the guide passage in a state where the upper and lower connection opening is closed.

A system for controlling inside/outside air in air conditioner may include an air conditioner including an upward discharge passage, through which air is discharged toward a front glass of a vehicle, a downward discharge passage, through which air is discharged toward a floor of the vehicle, the upward discharge passage and the downward discharge passage being separated from each other, a first intake door, an opening amount of which is determined according to a ratio between inside air and outside air introduced into the upward discharge passage, and a second intake door, an opening amount of which is determined according to a ratio between inside air and outside air introduced into the downward discharge passage; and a control unit configured of controlling the opening amounts of the first and second intake doors according to a heating load of the air conditioner and a humidity of the interior of the vehicle.

An air conditioner for a vehicle includes a casing that forms an air passage through which air flows, a blower fan to blow out air, and a heating device to heat air. The casing includes a passage portion through which air flows, a warm air passage that allows air to flow to the heating device, and a bypass passage that allows air to bypass the heating device. A width dimension of the passage portion in a second direction is larger than that of the heating device in the second direction, and is smaller than a height dimension of the passage portion in a first direction.

The invention relates to a heating, ventilation and/or air conditioning device (10) for a motor vehicle, comprising a housing (12) defining an air duct (11) for the passage of an airflow comprising—an inlet module (8), comprising at least one air inlet (15, 16), an air filter (70) being arranged within the inlet module (8), and—a distribution module (9) comprising at least one air outlet (27, 29, 30), the inlet module (8) and the distribution module (9) being detachably assembled to one another; according to the invention, the inlet module (8) is configured to be arranged in a first area of the vehicle, and the distribution module (9) is configured to be arranged in a second area of the vehicle, the air filter (70) being able to be removed from the second area of the vehicle. The invention also relates to a motor vehicle comprising such a device.

The present invention relates to an air conditioning apparatus for a vehicle and, more specifically, to an air conditioning apparatus for a heat pump system, wherein while blown air passes through a first area and a second area which are partitioned from each other by a first separation wall, air passing through the first area is cooled or heated and then supplied to the inside of a vehicle, and air passing through the second area is discharged to the outside, so that the air conditioning apparatus can be miniaturized and can easily cool or heat the inside of the vehicle.
