An HVAC system for a vehicle. The HVAC system including an evaporator case, a heater case, and a blower case. The heater case is in cooperation with the evaporator case to receive airflow from the evaporator case. The heater case includes a heat source and defines front passenger cabin airflow outlets and rear passenger cabin airflow outlets. The blower case is in fluid communication with the evaporator case and includes a single airflow generator that generates airflow through the evaporator case, through the heater case, and to both the front passenger cabin airflow outlets and the rear passenger cabin airflow outlets.

A thermal management system for a vehicle may include a refrigerant circuit in which a refrigerant circulates, as well as a heating circuit, a first coolant circuit configured for a temperature control of a drive device of the vehicle, and a second coolant circuit configured for a temperature control of an electrical store of the vehicle in which a coolant circulates. The system may further include a chiller incorporated in the refrigerant circuit and a chiller guide fluidically separate from the refrigerant circuit. The chiller guide may have a chiller path configured to conduct the coolant and which extends through the chiller, and may have a bypass path configured to conduct the coolant and which circumvents the chiller. The system may additionally include a chiller valve device configured to selectively fluidically connect the first coolant circuit and the second coolant circuit to the chiller path and the bypass path.

Heat flow management device for motor vehicles has a refrigerant circulation, a power train coolant circulation and a heating line heat carrier circulation. The refrigerant circulation includes a compressor, an indirect condenser, an expansion element, an ambient heat exchanger, an evaporator and a chiller. The power train coolant circulation includes a coolant pump, the chiller, an electric motor heat exchanger and a power train coolant radiator, wherein the heating line heat carrier circulation comprises a coolant pump, the indirect condenser and a heating heat exchanger, wherein the refrigerant circulation and the power train coolant circulation are directly thermally coupled with one another across the chiller. Refrigerant circulation and heating line heat carrier circulation are directly thermally coupled with one another across the indirect condenser. Power train coolant circulation and the heating line heat carrier circulation are only indirectly thermally coupled with one another across the refrigerant circulation.

An air-conditioning system for air-conditioning a passenger cell with a front region and a rear region may include a housing including an air inlet, a front outlet, a rear outlet, and a footwell outlet. The system may also include an evaporator for cooling an airflow and a heating device for heating the airflow arranged in the housing. A cold air space, a hot air space, a front mixing space, a layering mixing space, and a rear mixing space may be arranged within the housing. The system may also include a front flap configured to control a first connection opening connecting the hot air space to the front mixing space, a layering flap configured to control a second connection opening connecting the hot air space to the layering mixing space, and a rear flap configured to control a third connection opening connecting the hot air space to the rear mixing space.

Climate control device for motor vehicle conveys and conditions inflowing air for a passenger compartment includes a housing with a diffuser, a mixing zone and at least two flow paths through which two flows can be conducted in parallel. A heating heat exchanger is disposed in a first flow path to heat an air mass subflow. A heat exchanger is provided for cooling and/or dehumidifying inflowing air. A bypass flow path is provided through which air can flow in parallel to a flow channel with the heat exchanger. At least one flow guide mechanism opens and closes the bypass flow path. flow channel and bypass flow path open out with outlet ports into mixing zone. Outlet port of a bypass flow path is developed for specific discharge of an air mass subflow into first flow path in proximity of an opening site of first flow path into a mixing zone.

An air conditioning unit for a vehicle includes: an air conditioning case, a blower that draws air from an opening and blows the air radially outward from its rotation axis, a cooler disposed upstream of the blower, and a heater is disposed downstream of the blower. The air conditioning case includes an upper bypass passage through which the air bypasses the heater on an upper side of the heater, a lower bypass passage through which the air bypasses the heater on a lower side of the heater, a first opening provided downstream of the upper bypass passage, and a second opening provided downstream of the lower bypass passage. The opening of the blower faces an air outflow face of the cooler. A passage area of the upper bypass passage is larger than a passage area of the lower bypass passage.

An air-conditioning unit of a motor vehicle may include a fan, an evaporator, and a heat exchanger. The heat exchanger may be arranged downstream of the evaporator. The evaporator and heat exchanger may both be arranged in a housing. The air-conditioning unit may also include a first bypass channel bypassing the evaporator. The first bypass channel may be arranged centrally on a side of the evaporator. A width of the first bypass channel may be smaller than a width of the side of the evaporator on which the first bypass channel is arranged.

An air conditioning case in an air conditioning unit for a vehicle forms a first air passage, a second air passage bypassing the first air passage, and a mixing space connected to a first blowing port and a second blowing port through which air is blown out into a vehicle interior. A cooling heat exchanger cools and allows air to flow into the first air passage and the second air passage. A heating heat exchanger is disposed in the first air passage. A tunnel forming portion provides a tunnel passage into which a part of air from the first air passage flows. The tunnel forming portion includes a first outflow portion connected to the first blowing port, and a second outflow portion connected to the second blowing port, and separates the air flowing in the tunnel passage from the air flowing from the second air passage.

A cab for an agricultural working vehicle has a cab base and a cab roof, between which a windshield and side windows are situated in a frame structure, and a driver's seat situated on the cab base. There is at least one air treatment device for cooling and heating an inlet air flow which is supplied to the cab through an intake duct. The air treatment device has at least one first air distribution duct having at least one first air outlet opening, and at least one second air distribution duct having at least one second air outlet opening. The first air outlet opening outputs a first air flow substantially along the windshield and the second air outlet opening outputs a second air flow directed in the direction of the driver's seat. The first air flow has a higher temperature than the second air flow.
