An air-handling system for a motor vehicle includes a conditioning section having an evaporator core and a heater core. The conditioning section is separated into a primary zone and a secondary zone at a position disposed upstream of the heater core. The heater core extends partially into each of the primary zone and the secondary zone. A primary door assembly is disposed within the conditioning section at a position upstream of the heater core and a secondary door assembly is disposed within the secondary zone of the conditioning section at a position downstream of the primary door and upstream of the heater core.

In an air conditioning case, a blower sucks air flowing out from first and second upstream side ventilation paths from one side in an axial direction of a fan axis by rotation of a blower fan and allows the sucked air to flow to first and second downstream side ventilation paths. An upstream side guide member is provided on one side in the axial direction with respect to the blower fan and guides the air to the blower fan. Further, the upstream side guide member has a twisted shape and guides the air to the blower fan along the twisted shape.

A module for accommodating electronic circuitry which advantageously is able to take advantage of air in a climate system for cooling of the electronic circuitry. In one aspect, there is provided a module for accommodating electronic circuitry in a vehicle, the module includes: at least one attachment surface for attachment of electronic circuitry thereon, an air guiding structure for receiving an air flow for cooling of the attachment surface, the air guiding structure having a wall member including the attachment surface such that the wall member provides a thermal path between the attachment surface and the air in the air guiding structure, wherein the air guiding structure includes an inlet configured to receive air for cooling of the attachment surface wherein the air flow is an air flow used for climate control in the vehicle.

The invention relates to a heating, ventilation and/or air conditioning device for a motor vehicle, having an air inlet box with a plurality of walls and a spiral box arranged downstream of the air inlet box with respect to the flow of an air flow. The air inlet box further includes at least one first air inlet for the entry of a first air flow and at least one second air inlet for the entry of a second air flow. The air inlet box has a first internal duct made of porous material arranged to connect the first air inlet to the inlet of the spiral box.

An air conditioning unit includes a conditioning chamber, a fan with a fan air input and a fan air output, and an evaporative unit. The fan and the evaporative unit are arranged in the conditioning chamber. The fan draws in entry air to enter the air conditioning unit, then through the evaporative unit, to condition the entry air to produce conditioned air. Within the conditioning chamber, the fan is positioned and configured such that at least 30% of an area of the fan air output are positioned above an average top surface of the evaporative unit, and that air from the at least 30% of the area of the fan air output is directed towards a wall of the conditioning chamber prior to being redirected downwards and through the evaporative unit.

A cooling and battery cooling mode is performed to release the heat from the refrigerant in a heat releasing unit and an outdoor heat exchanger and to absorb the heat into the refrigerant in a heat absorbing unit and a refrigerant-heat medium heat exchanger, and a heating and battery cooling mode is performed to release the heat from the refrigerant in the heat releasing unit and to absorb the heat into the refrigerant in the outdoor heat exchanger and the in-vehicle device heat exchanger. In a case where the cooling and battery cooling mode is performed, when a temperature of the heat absorbing unit is lower than a target value of the temperature of the heat absorbing unit even though the flowing of the refrigerant into the heat absorbing unit is blocked, the operation mode is moved to the heating and battery cooling mode.

An air conditioner is configured to be switchable between a heating mode and a cooling mode. In the cooling mode, a high-temperature heat medium circulates between a high-pressure side refrigerant-heat medium heat exchanger and a high-temperature heat medium-outside air heat exchanger in a state where a refrigerant circulates in an air-cooling heat exchanger. In the heating mode, the high-temperature heat medium circulates between the high-pressure side refrigerant-heat medium heat exchanger and an air-heating heat exchanger, while a low-temperature heat medium circulates between a low-pressure side refrigerant-heat medium heat exchanger and a low-temperature heat medium-outside air heat exchanger, in a state where the refrigerant circulates in the low-pressure side refrigerant-heat medium heat exchanger.

An air-conditioning apparatus for a vehicle and a control method of the same are provided to inhibit a closing degree of a door in closing the door from being insufficient, secure high quietness in a vehicle cabin immediately after the door is closed, and lower energy consumption of the vehicle. An air-conditioning apparatus for a vehicle includes an inside-outside air switching damper including a damper switching actuator, an air-conditioning control switch, a control unit, and door opening-and-closing sensors. The control unit includes two timers and a memory. When an IG switch is in an OFF state, the control unit sets the inside-outside air switching damper to an intermediate mode when the door becomes an open state, thereafter sequentially starts the timers when the door becomes a closed state, and returns the inside-outside air switching damper to a previous state to opening of the door after waiting until the timers expire.

An air conditioning system for a vehicle may include a refrigerant line through which a refrigerant circulates and an evaporator and a condenser are connected to each other; and a first core and a second core for indoor air conditioning, wherein the first core includes a first inlet and a first outlet through which a coolant passing through the evaporator is introduced and discharged, respectively, the second core includes a second inlet and a second outlet through which a coolant passing through the condenser is introduced and discharged, respectively, and the first core and the second core are connected to each other through a connection line, and the connection line is provided with a first valve selectively connecting the first core and the second core through the connection line.

An air conditioning device for an electric vehicle includes: a housing having an air conditioning passage connecting an air inlet port to an air discharge port; an evaporator, an air heater, and an electric heater, which are positioned in series in the air conditioning passage in the housing; and a bypass door positioned after the evaporator in the air conditioning passage in the housing and configured to selectively allow some of air passing through the evaporator to bypass the air heater and the electric heater to the air discharge port.
