Disclosed is a vehicle air conditioning device, which is an air conditioning device using an integrated heat pump system, and in which left and right independent air conditionings can be implemented in a simple structure such that the left and right air volumes may be automatically controlled, the ability to mix hot and cold air is improved, and sufficient space can be secured inside a vehicle.

An air-conditioning unit for a vehicle includes an air conditioning case, a blower, and a rectifying mechanism. The blower has a blower fan rotating around a fan axis and arranged in an in-case passage of the air conditioning case, and blows out air drawn from one side in an axial direction of the fan axis by rotation of the blower fan. The rectifying mechanism is arranged downstream of the blower fan in the in-case passage, and the air passes through the rectifying mechanism. The blower fan is arranged so that the other side of the fan axis that is opposite to the one side extends toward a downstream side of the in-case passage. The rectifying mechanism suppresses a swirling flow generated by the rotation of the blower fan in the air blown out from the blower fan as compared with the blown-out air prior to flowing into the rectifying mechanism.

A thermal management system for an electric vehicle includes an interior air conditioning part including an air inflow part, an air discharge part, a cooling core, a heating core arranged between the cooling core and the air discharge part, and an adjustment door. The adjustment door is selectively adjustable to control whether air from the cooling core may flow into the heating core. A heat transfer line connects an electric part core to the heating core for transferring that heat of the electric part to the heating core, in order to allow heat dissipation of the electric part through the heating core.

A vehicle includes an outside air passage, accommodation cases, an outside air communication opening, an outside air valve, a case communication opening, and a case valve. The outside air passage is capable of allowing outside air to flow through the outside air passage. The accommodation cases are disposed to be compatible with the outside air passage and accommodate predetermined units independently. The outside air communication opening is capable of allowing communication between the outside air passage and the accommodation case. The outside air valve is capable of opening or closing the outside air communication opening. The case communication opening is capable of allowing communication between adjacent ones of the accommodation cases. The case valve is capable of opening or closing the case communication opening.

A heating, ventilating, and air conditioning (HVAC) apparatus for a vehicle includes: a case, which is configured to communicate with the outside of the vehicle and which includes a discharge flow path connected to an interior of the vehicle; an outside air inlet, which is located in the case and into which air is introduced from the outside of the vehicle; an inside air inlet configured to communicate with the interior of the vehicle; a filter unit located adjacent to the discharge flow path; an inside/outside air switching door provided adjacent to the outside air inlet and the inside air inlet and configured to selectively open the outside air inlet and the inside air inlet; and an auxiliary switching door, which includes a depression located at a lower end of the filter unit and which is selectively opened so as to allow the depression and an outdoor outlet to be fluidly connected.

A method for operating an air conditioning system, which may include a heating device, to condition air in a vehicle interior of a motor vehicle. At least one first air path and at least one second air path may each fluidically communicate with the air conditioning system and each open out into the vehicle interior. The method may include guiding the air from the vehicle interior via one of (i) the at least one first air path and (ii) the at least one second air path to the air conditioning system as a function of an operating state set in the air conditioning system. The method may also include guiding the air from the air conditioning system via the other of the one of (i) the at least one first air path and (ii) the at least one second air path into the vehicle interior.

A ventilation system is adapted to be used in a vehicle. The vehicle includes a vehicle body that defines an interior space. The ventilation system includes a vent pipe and a fan. The vent pipe is adapted to be disposed on the vehicle body, and has an outside communicating end via which the vent pipe is adapted to communicate with the outside of the vehicle body, and an inside communicating end via which the vent pipe is adapted to communicate with the interior space. The fan is disposed in the vent pipe, and is configured to be activated to produce airflow from the outside communicating end to the inside communicating end.

An air conditioner includes an air conditioning unit installed in a cabin, and a supply unit supplying air conditioned by the air conditioning unit to the cabin. The air conditioning unit includes a refrigeration cycle device having a compressor, a radiator, a decompression device, and an evaporator. One of the radiator and the evaporator functions as a use-side heat exchanger that generates conditioned air by heat exchange between refrigerant and air. The refrigeration cycle device has a high-pressure protection device that discharges the refrigerant to the outside when the pressure of the refrigerant flowing through a passage, which is defined from a refrigerant discharge side of the compressor to a refrigerant inlet side of the decompression device, exceeds a predetermined reference pressure. The high-pressure protection device is configured to discharge the refrigerant to the outside through an outside communication portion communicated with the outside of the cabin.

An air conditioner includes a first inlet-side inside/outside air switching part, a first outlet-side outside/inside air switching part, a second inlet-side inside/outside air switching part and a second outlet-side inside/outside air switching part. In a dehumidifying heating mode, the first outlet-side inside/outside air switching part makes a switch to a ventilation path that guides air having passed through a first heat exchange part into a space to be air-conditioned, and the second inlet-side inside/outside air switching part makes a switch to a ventilation path that guides outside air to a second heat exchange part. In a defrosting mode, the second inlet-side inside/outside air switching part makes a switch to a ventilation path that guides inside air to the second heat exchange part, and a flow rate of refrigerant flowing through the second heat exchange part is reduced more than in the dehumidifying heating mode.

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.
