A vehicular air conditioner includes a partitioning portion which separates an inside of an air-conditioning casing into an inside-air passage through which an inside air flows and an outside-air passage through which an outside air flows, a cooling heat exchanger extending across both the inside-air passage and the outside-air passage, a heating heat exchanger heating the inside air and the outside air on a downstream side of the cooling heat exchanger in an air flow, and a restriction portion provided downstream of the cooing heat exchanger in the air flow and limiting inflow of the inside air into the outside-air passage on the way to the heating heat exchanger. The restriction portion is located in the inside-air passage between the cooing heat exchanger and the heating heat exchanger, and includes a first temperature regulation door that regulates a temperature of air supplied to the vehicle compartment.

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.

A heating, ventilation, and air conditioning (HVAC) apparatus for an automotive vehicle may include an internal volume divided into upper and lower regions, and configured for blowing the air to a defrost vent and a front seat face vent is made through the upper region, and blowing the air to a front seat foot vent and a rear seat vent is made through the lower region.

A triple-zone heating, ventilation and air conditioning (HVAC) apparatus for an automotive vehicle may be configured to mix cold air passing through an evaporator and warm air passing through a heat exchanger with each other and blow the mixed air to a front seat foot vent through a front seat foot door and to a rear seat vent through a rear seat door.

An HVAC system for a vehicle includes a housing, an evaporator disposed in the housing, and a heater disposed in the housing. The HVAC system further includes a bypass opening defined between an upper end of the evaporator and an upper end of the heater and an intermediate chamber defined by the evaporator, the heater, the housing, and the bypass opening. The HVAC system further includes an upper outlet passage configured to direct air from the HVAC system into a passenger compartment of a vehicle. The evaporator is configured to output a first stream of air into the intermediate chamber and the HVAC system is configured to operate in a first operating condition in which a first portion of the first stream of air will pass through the heater and a second portion of the first stream will bypass the heater by passing from the intermediate chamber through the bypass opening and into the upper outlet passage.

The present invention relates to an air conditioning system and, more particularly, to an air conditioning system comprising, within a single air conditioning case: a cool air passage in which an evaporator is installed; a warm air passage in which a condenser is installed; an installation space portion in which air conditioner parts such as a compressor are installed; and an air discharge passage for discharging, to the outside, air unnecessary for cooling and heating, thereby enabling attachment and detachment inside a vehicle, and enabling use as a portable air conditioner as well as a vehicle air conditioner. In addition, as the system is capable of cooling and heating, a separate heater core or PTC heater for heating is not required, thereby the structure is simple, and the system is capable of controlling cooling and heating modes through a single operation door, thereby allowing the system to be miniaturized.

An air handling system for a vehicle comprises a conditioning section for controlling a temperature of a flow of air, a mixing section disposed downstream of the conditioning section with respect to a direction of the flow of the air, and a delivery section disposed downstream of the mixing section with respect to the direction of the flow of the air. The delivery section includes a first chamber, a second chamber, and a third chamber. A dividing plate separates each of the second chamber and the third chamber into a first side portion to a first side of the dividing plate and a second side portion to an opposing second side of the dividing plate. The second side portion of the third chamber is configured to primarily direct the flow of the air towards a rear seat area of the vehicle.

A heat exchanger includes multiple tubes, multiple fins, and a partition wall. The multiple fins are stacked alternately with the tubes to form a core including a first section and a second section. The partition wall partitions between the first section and the second section. The first section has multiple drain passages in the vicinity of the partition wall.

An insert is configured to be inserted into a heat exchanger having a plurality of tubes. The insert includes a base and a multiple blades. The blades are extended from the base. At least one of the blades has a spring portion. The spring portion is resiliently deformable and configured to be resiliently inserted between two of the tubes. The spring portion includes two arms. One of the two arms has one thin portion defining one recess dented in one direction in a thickness direction. The other of the two arms has the other thin portion defining the other recess dented in the other direction in the thickness direction. The one thin portion and the other thin portion are resiliently movable in a width direction within a clearance formed by the recesses, while overlapping one another in the thickness direction.

The air conditioner for a vehicle has a centrifugal fan and a housing. The centrifugal fan has a fan suction port and a rotary shaft and rotates centering on a rotational axis of the rotary shaft. The housing has a fan housing chamber, an introduction passage, and a wall. The fan housing chamber houses the centrifugal fan. The introduction passage guides air, which flows from an outside of the housing into the housing, to flow toward the centrifugal fan in a first direction intersecting with the rotational axis. The wall partitions the fan housing chamber and the introduction passage from each other and has an opening that faces the fan suction port. The wall has a rim defining the opening and being provided with an annular protruding portion. The annular protruding portion protrudes from the wall toward the introduction passage and covers the opening.
