The invention relates to a surface temperature-controlling device, in particular for use in vehicles, comprising a first air-distributing layer which has multiple air inlets extending through the first air-distributing layer and multiple air outlets extending through the first air-distributing layer, and a second air-distributing layer which fluidically connects air inlets and air outlets of the first air-distributing layer, wherein the air inlets are designed to introduce pre-heated or pre-cooled air into the second air-distributing layer, and the air outlets are designed to discharge air out of the second air-distributing layer.

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.

An air flow device for a vehicle including an instrument panel dashboard, and a blower, the air flow device comprising a first outlet on a front upper surface portion of the instrument panel dashboard from which an air is sent along the front upper surface to a first inlet on the instrument panel dashboard into which the air blown from the first outlet is drawn; and a second outlet on a back upper surface portion of instrument panel dashboard from which an air is sent along the back upper surface to a second inlet on the instrument panel. The blower outlets are installed so as to open parallel to the blower inlets along an upper surface portion of the instrument panel dashboard.

A heat pump system for a vehicle is provided. The system includes a battery coolant line connected to a battery module. A cooling device selectively connected to the battery coolant line includes a radiator and a first water pump, to circulate a coolant therein. A first chiller is disposed in the battery coolant line and connected to a refrigerant line of an air conditioner to adjust a temperature of a coolant. A second chiller is selectively connected to the coolant line and selectively connected to the refrigerant line to increase a temperature of a coolant by selectively exchanging heat between the coolant and a refrigerant flowing into the second chiller. An integrated control valve is connected to the refrigerant line, the first connecting line, and the second connecting line to adjust a refrigerant flow direction and to selectively expand a refrigerant passing through the integrated control valve.

An HVAC module for an automotive vehicle includes a housing defining an air inlet, an upper front zone outlet, a lower front zone outlet, and a rear zone air outlet. An evaporator and a heater downstream of the evaporator are disposed in the housing. The air inlet of the housing is divided by a first divider into an OSA portion exclusively receiving outside air and a REC portion exclusively receiving recycled air. Each of the evaporator and the heater has a respective OSA portion receiving the outside air and a REC portion receiving the recycled air entering the HVAC module through the inlet. A second divider between the evaporator and the heater directs the outside air from the REC portion of the evaporator to the REC portion of the heater. Two temperature doors control access of separate partial streams of the recycled air from the evaporator to the heater.

An HVAC system according to an example of the present disclosure includes a blower rotatable about an axis. The blower has a first blower section and a second blower section fluidly isolated from the first blower section. An inlet assembly at an axial end of the blower includes a first compartment configured to control fluid flow through the first blower section and a second compartment configured to control fluid flow through the second blower section.

An air flow device for an instrument panel which blows an air from the instrument panel at a front of a vehicle compartment of an automobile to make the air flow to the vehicle compartment, includes a blower, a blower outlet on the instrument panel, from which an air sent from the blower to which the blower outlet is coupled is blown to the vehicle compartment, and a blower inlet on the instrument panel for the blower outlet, into which the air blown from the blower outlet is drawn. The blower outlet is installed so as to open to the blower inlet along a surface of the instrument panel while the blower inlet is installed so as to open to the blower outlet along the surface of the instrument panel.
