Disclosed herein is a heat pump system for a vehicle which includes an evaporator mounted on a cold air passageway inside an air-conditioning case, a condenser mounted on a warm air passageway, a first blower mounted at an inlet side of the cold air passageway of the air-conditioning case, a second blower mounted at an inlet side of the warm air passageway and an intake duct mounted between the first blower and the second blower to supply indoor air and outdoor air to the first blower and the second blower respectively, thereby maximizing space efficiency because using just one intake duct for the two blowers, and reducing the size and manufacturing costs of the heat pump system.

A blower device includes a centrifugal fan that sucks air from one side of the blower device in an axial direction, and an air flow guide disposed between the centrifugal fan and the other side of the blower device in the axial direction. A first air flow from the centrifugal fan is bent toward the other side in the axial direction. A second air flow from the centrifugal fan is bent toward the other side in the axial direction, and then bent inward in the radial direction. A ratio of a pressure loss in the second air flow to a pressure loss in the first air flow before a downstream end of the air flow guide is smaller than a ratio of a pressure loss in the second air flow to a pressure loss in the first air flow before an upstream end of the air flow guide.

A heating, ventilation, and air conditioning (HVAC) system for a vehicle may include a blower unit, an evaporator unit, and a conditioning unit. The blower unit includes a fan that draws in air into the HVAC system. The evaporator unit is downstream from the blower unit, and the air drawn in by the fan flows through an evaporator of the evaporator unit. The conditioning unit is downstream from the evaporator unit. The blower unit is disposed below the conditioning unit.

A vehicle air conditioning apparatus includes an air conditioning case including a case body having a case opening that is open to an air conditioning opening, and a case cover that can open and close the case opening. The case cover can be attached/detached to/from the case body via the air conditioning opening outside of the vehicle interior. An evaporator and a heater can be attached/detached to/from the case body via the air conditioning opening outside of the vehicle interior, while the case cover is removed from the case body to open the case opening.

A heating, ventilation, and air conditioning (HVAC) includes a case, an ambient inlet port defined in the case and configured to selectively receive air from outside the cabin of a vehicle, a recirculation inlet port defined in the case and configured to selectively receive air from inside the cabin of the vehicle, at least one discharge port configured to selectively discharge at least a portion of an airflow from the case to inside the cabin of the vehicle, and an extractor port disposed within the case and configured to discharge at least a portion of the airflow from the case to the ambient environment.

An environmental control system for thermally conditioning air within an enclosed space is provided. The system includes a refrigerant circuit having a compressor, an indoor heat exchanger, an expansion device, and an outdoor heat exchanger. The system also includes an exhaust flowpath having a first inlet for receiving an exhaust flow of thermally conditioned air from the enclosed space and an outlet for discharging the exhaust flow to an external environment. A heat transfer section of the outdoor heat exchanger is located in the exhaust flowpath The exhaust flowpath is configured to direct the exhaust flow of thermally conditioned air through the heat transfer section of the outdoor heat exchanger.

A vehicular air conditioning system includes an air conditioning case with internal flow path introducing air discharged from a blower and feeding the air into a passenger room, a cooling and heating heat exchangers cooling and heating the air flowing along the internal flow path, and a plurality of vents discharging cold and hot air passed through the cooling and heating heat exchanger into the passenger room. The internal flow path is formed in an up-down direction for air flow path to extend in the direction of gravity. The cooling and heating heat exchangers are installed sequentially from the lower to upper side in the direction of gravity to correspond to the air flow path. The vents discharge the cold and the hot air passed through the cooling and heating heat exchanger into the passenger room while distributing cold and hot air in a front-rear direction of a vehicle.

An electric vehicle having a heat exchanger formed in an aerodynamic airfoil shape comprising one or more body panels disposed along an outer surface of the vehicle having one or more fluidic chambers or micro-channels. The heat exchanger is adapted to provide effective and highly efficient heat transfer, and also to provide substantially reduced or negligible contribution to the aerodynamic drag. The heat exchanger includes a supplemental heat exchange system wherein at least a portion of the heat exchange capacity is provided by an inner heat exchange surface of the heat exchanger exposed to an interstitial space within the vehicle. Airflow is forced, via a fan for example, from an aerodynamically-efficient inlet, over the inner heat exchange surface, and exhausted through an aerodynamically-efficient outlet, thereby providing a supplemental heat exchange system including substantially reduced or negligible contribution to the aerodynamic drag.

In an air conditioner system for a mobility device, some inside air communicates with an outdoor heat exchanger when outside air for indoor ventilation is introduced, thereby improving heat pump performance. That is, by allowing indoor cold air to communicate with the outdoor heat exchanger upon mixing the inside and outside air during indoor cooling and allowing indoor warm air to communicate with the outdoor heat exchanger upon mixing the inside and outside air during indoor heating, it is possible to increase the heat pump efficiency as the outdoor heat exchanger recovers the heat of the indoor air during indoor cooling and heating. In addition, introduced is an air conditioner system for a mobility device in which a structure is simplified as inside air may be selectively transmitted to an outdoor heat exchanger side only by applying a flow path structure and a valve.

A vehicular air-conditioning device for cooling and heating includes a refrigerant circulation passage formed in a housing, an air circulation passage located in the housing and configured to perform heat exchange with the refrigerant circulation passage, and a controller configured to receive an interior temperature from an interior temperature sensor of a vehicle and to operate a first switching door and a second switching door. The air circulation passage includes a blower, a first flow path formed between a first duct part located at one end of the housing and the blower, the first switching door configured to selectively open the first duct part, a second flow path formed between a second duct part located at the other end of the housing and the blower, and the second switching door configured to selectively open the second duct part.
