A HVAC system for a motor vehicle having a housing, wherein the housing has an air inlet for admitting air and a cold air path in which cold air flows is provided in the housing and a warm air path in which warm air flows is provided in the housing, wherein the warm air path and the cold air path open into a mixing chamber, wherein a mixing flap is provided for controlling the proportion of cold air flowing into the mixing chamber and the proportion of warm air flowing into the mixing chamber, wherein the mixing flap is arranged rotatable about an axis and is driven by a flap actuator which has a drive shaft, wherein a gear with a nonlinear translation characteristic is provided between the mixing flap and the drive shaft.

A door unit for an air conditioning system includes a stationary inner screen part, an outer casing part rotatable between different operational positions in relation to the inner screen part, and a flap member attached to the outer casing part. The outer casing part includes first and second inlet openings. The door unit directs a first flow of air in a first air flow channel and a second flow of air in a second air flow channel to a third air flow channel or to the third air flow channel and a fourth air flow channel. The flap member blocks the first air flow channel or the second air flow channel, wherein an internal volume of the door unit enclosed by the inner screen part and the outer casing part forms the fourth air flow channel.

The present invention relates to an air conditioner for a vehicle, and more particularly, to an air conditioner for a vehicle in which heating performance may be improved using an auxiliary heating heat exchanger and stability of a passenger may be improved by providing the auxiliary heating heat exchanger in an engine room.

An air-conditioning unit includes an air-conditioning case including an opening through which air flows, a cooler disposed in the air-conditioning case to cool air flowing to the opening, a heater disposed in the air-conditioning case to heat air flowing to the opening, and an adjusting member disposed to cover the opening and adjusting airflow passing through the opening. The adjusting member is produced separately from the air-conditioning case and includes a first region and a second region. The second region includes a high resistance member giving higher resistance to the airflow than the first region. The first region includes a low resistance member giving lower resistance to the airflow than the second region. The low resistance member is a partition dividing the first region into plural air passing parts through which air flows. The high resistance member is a plate member including a part to interfere the airflow.

The present invention relates to a vehicle air conditioner and, more specifically, to a vehicle air conditioner which supplies, to a variable heat exchanger, condensate water and air, that have been blown by means of a supply part and passed through an evaporator, so as to enable sub-cooling and overall performance of the variable heat exchanger to be improved during cooling, thereby further increasing cooling performance, and which may use air and condensate water as a heat-absorbing heat source during heating so as to further increase the heat absorption amount of the variable heat exchanger, so that heating performance may be further increased, and thus overall power consumption for air conditioning may be reduced and an increase in heat pump system performance may be promoted.

A control system and method for a heating system of an electric vehicle or hybrid vehicle is embodied such that when there is a heating request for a passenger compartment of the vehicle, a heating mode is set in order to heat the passenger compartment by heat from a heating circuit. In a mixed mode, an excess heat in the heating circuit is output to the surroundings, or in an excess mode, the excess heat is retained in the heating system, in order to satisfy a heating request. In the mixed mode, a degree of opening of the heating circuit is set such that only a partial quantity of coolant from the heating circuit is exchanged with a cooling circuit. The mixed mode is activated if the excess heat in the heating circuit exceeds a threshold value which is determined in accordance with an external temperature.

A thermal management system includes an interior air conditioner including a housing provided with a cooling duct, a heating duct, an inside air inlet, an outside air inlet, and an internal outlet, and an external outlet, wherein the internal outlet of the housing is connected to an inside the vehicle and the external outlet is connected to an outside of a vehicle, an evaporation core is provided in the cooling duct of the housing, a condensing core is provided in the heating duct of the housing, air conditioning of the inside the vehicle is performed through the evaporation core and the condensing core. The evaporation core and the condensing core are connected to a refrigerant line provided with a compressor and an expansion valve and connected to multiple electronic components of the vehicle through a coolant.

A vehicle air conditioner, and more specifically, to a vehicle air conditioner in which an air conditioning module and a cooling module are integrally formed, thereby enabling miniaturization so as to enable increased space utilization inside an engine room, and enabling increased manufacturability.

The present invention relates to an air conditioner for a vehicle and, more particularly, to an air conditioner for a vehicle which is capable of miniaturization by integrally forming an air conditioning module and a cooling module so as to increase space utilization in an engine room and further enhance manufacturability.

A heating, ventilation, and air conditioning (HVAC) system for a cargo vehicle includes an evaporator, a first door, a condenser, a second door, a freezing room, a refrigerating room, a warming room, and a controller, wherein the controller is configured to control an amount of opening of each of the first internal air and external air door, the second internal air and external air door, the first door, and the second door and an amount of driving of each of the evaporator and the condenser in response to an outside air condition of a vehicle, controlling temperature of each of the freezing room, the refrigerating room, and the warming room.
