An air-conditioning apparatus for an electric vehicle and a method of controlling the same, may include a heat exchanger performing heat exchange between a first fluid and a second fluid while the first fluid and the second fluid flow separately from each other therethrough; a heat source connected to the heat exchanger through a line through which the second fluid flows to allow the second fluid to circulate between the heat exchanger and the heat source, and heating or cooling the second fluid; a circulator imparting a circulation force to the second fluid such that the second fluid circulates between the heat exchanger and the heat source; and a controller determining a required flow rate of the second fluid by use of a flow rate of the first fluid flowing through the heat exchanger and controlling the circulator on the basis of the required flow rate of the second fluid.

A system for controlling movements of doors of an HVAC module includes an actuation gear and an intermediate cam. A main door includes a first portion and a second portion having a first guide. The first portion engages with actuation gear to enable linear movement of the main door. A slave door includes a second engagement element and moves between a blocking and unblocking position based on movement of main door. The intermediate cam moves angularly and includes a first engagement element and a second guide. The first engagement element interacts with the first guide, and the second guide interacts with second engagement element to facilitate angular movement of slave door in response to movement of the main door. The first guide includes a bend positioned to enable angular movement of the slave door after the main door moves a pre-determined distance.

A system for heating a cabin of a vehicle can include: a liquid-cooled charge air cooler configured to receive a liquid, to receive heated air from one of a turbocharger and a supercharger of the vehicle, to cool the heated air via the liquid, thereby heating the liquid, to output the cooled air to an intake manifold of an engine of the vehicle, and to output the heated liquid; and a multi-function heat exchanger connected to the liquid-cooled charge air cooler, the multi-function heat exchanger configured to receive the heated liquid outputted by the liquid-cooled charge air cooler, to generate heated air via the heated liquid, and to output the heated air into the cabin of the vehicle, thereby heating the cabin of the vehicle.

A heat exchanger has a fluid flow passage defined between first and second plates, and at least one through fitting having a one-piece construction. The through fitting has a first portion extending through a first hole of the first plate, a second portion extending a second hole of the second plate, and a radially outwardly extending third portion located between the first and second plates. The third portion of the through fitting has a first radially-extending surface in contact with the inner surface of the first plate and a second radially-extending surface in contact with the inner surface of the second plate. At least one communication passage is provided through the third portion of the through fitting between the fluid flow passage and the hollow interior of the through fitting. A plurality of the heat exchangers may be fluidly connected in parallel flow arrangement.

A vehicle climate control system includes a heat exchanger to heat ambient air using engine waste heat, and a plurality of positive temperature coefficient (PTC) heating elements to heat air passed through the heat exchanger. The vehicle also includes a controller programmed to, while the vehicle is driven without engine propulsion, issue a command to sequentially de-energize the PTC heating elements before an upcoming engine activation. The sequential de-energization of the PTC heating elements is performed according to a schedule that is based upon a power surge dissipation time.

Methods and systems are provided for a cooling assembly for a vehicle. In one example, the cooling assembly may be a non-rectangular cooler positioned in a front end of the vehicle with an entry duct continuous with the non-rectangular cooler and arranged upstream of the non-rectangular cooler and an exit duct also continuous with the non-rectangular cooler and arranged downstream of the non-rectangular cooler.

Disclosed is a vehicle air conditioner, wherein an air conditioner of an integrated heat pump system enables the improvement of cold air and warm air mixing characteristics so as to decrease left-right temperature differences, enables the implementation of independent left-right air conditioning, and enables the sufficient securement of an interior space.

An air-conditioning system, in particular for a motor vehicle, having a refrigerant circuit, which has an evaporator and a condenser, and a coolant circuit, wherein the refrigerant circuit and the coolant circuit are thermally coupled to each other, in particular in the region of the evaporator and in the region of the condenser, wherein the coolant circuit has a line system having junctions, wherein a heating body, a cooling body, an outside heat exchanger, an additional heat source, a first bypass line, and a second bypass line are integrated into the line system, wherein the first bypass line bypasses the additional heat source from the cooling body to the outside heat exchanger, and/or the second bypass line bypasses the additional heat source from the heating body to the outside heat exchanger.

A heating, ventilating, and air conditioning (HVAC) system of a vehicle is provided. The system replaces a cooling water circuit having a complex configuration and a separate heat pump system for recovering waste heat of an electric vehicle by changing an air flow path for supplying heating and cooling air and secures an indoor space by disposing an HVAC in an engine room.
