The present disclosure describes an air conditioning apparatus comprising an air conditioning case defining an airflow passage, an evaporator accommodated in the air conditioning case, a first blower located at an upstream side of the evaporator creating a first airflow in the airflow passage, a second blower located at an upstream side of the evaporator creating a second airflow in the airflow passage, and a controller electrically connected to the first blower and the second blower. The controller controls the first blower and the second blower based on a target total airflow amount. The first airflow and the second airflow are mixed at the upstream side of the evaporator. The air conditioning apparatus further comprises means for preventing the first airflow from being directed into the second blower.

A vehicle includes an air conditioning system, a high voltage equipment, a cooling fan, and an intake duct. The air conditioning system is to condition air in an interior of the vehicle which has a vehicle height direction. The cooling fan is to send cooling air which has passed through the air conditioning system to the high voltage equipment. The cooling fan has an intake port. The intake duct is connected to the intake port from upward in the vehicle height direction to supply the cooling air to the cooling fan. A lowermost part of the intake port in the vehicle height direction is positioned higher than a lowermost surface of a duct flow path of the intake duct in the vehicle height direction.

A vehicle includes a heating, ventilation and air conditioning (HVAC) system for heating and cooling a passenger compartment. The HVAC system includes a refrigerant loop and a coolant loop, and an auxiliary coolant loop for heating and cooling at least a portion of the passenger compartment. The auxiliary coolant loop includes a pump for moving a coolant, within the auxiliary coolant loop, through a first heat exchanger coupled to the refrigerant loop via an expansion device, a second heat exchanger positioned within the passenger compartment, and a third heat exchanger coupled to the coolant loop. A flow control valve controls a flow of coolant to the third heat exchanger. The temperature of the coolant within the auxiliary coolant loop is controlled utilizing the flow valve and the pump. The first and third heat exchangers may be in parallel for controlling the movement of coolant there between to control temperature.

The device also includes one first chamber for mixing the flow of air which is connected fluidically to the first air outlet and at least one second chamber for mixing the flow of air which is connected fluidically to the second air outlet.

A vehicle-body structure may include a floor panel, a dash panel extending upward from a vehicle front portion of the floor panel and partitioning a vehicle front portion of an occupant space, a cooler disposed on a vehicle front side of the dash panel, a control device disposed in the occupant space, and a supply pipe through which a heat exchange medium subjected to heat exchange at a heat exchanger is supplied to the control device. The heat exchanger may be closer to the control device than a powertrain PT mounted on an automobile.

An air conditioning system is provided with an integrated heat exchanger. The air conditioning system generates heating air or cooling air through the integrated heat exchanger that adjusts the temperature of conditioning air by circulating coolant, thus securing cooling and heating efficiency. The air conditioning system adjusts temperature by the coolant circulated in the integrated heat exchanger such that a temperature adjustment door for adjusting the temperature of the conditioning air is eliminated, the number of components is decreased, and the size of an overall package is reduced.

A duct apparatus for a mobility vehicle secures an interior space by providing a battery case under a body floor, has a simplified cooling structure by cooling a battery module using inside air.
