Claim:
1. An HVAC device for a vehicle that performs air conditioning and operates using stored electric power as a power source, the HVAC device comprising: a compressor; a first blower disposed along ventilation pipes for taking in interior air of the vehicle through a vehicle interior air intake duct in communication with the first blower; an evaporator and dehumidifying member disposed along the ventilation pipes and in communication with the first blower; a condenser and an electrical heating unit disposed along the ventilation pipes and in communication with the first blower; a vehicle interior air reflux duct disposed along the ventilation pipes and in communication with first blower and the interior of the vehicle; a second blower disposed along the ventilation pipes for taking in air outside of the vehicle through an outside air introduction duct; and a first exhaust duct and a second exhaust duct disposed along the ventilation pipes and in communication with the second blower; wherein the HVAC device includes a heating and dehumidifying operation mode and actuation of the compressor and first blower creates a first flow path introducing interior air of the vehicle via the vehicle interior air intake duct, supplying the interior air of the vehicle to the evaporator and dehumidifying member, to the condenser, to the electric heating unit, and back to the vehicle interior via the vehicle interior air reflux duct; wherein the HVAC device includes a regenerating operation mode and actuation of the compressor and the second blower creates a second flow path introducing outside air via the outside air introduction duct, supplying the outside air to the electric heating unit and the condenser, the evaporator and dehumidifying member, and exhausting the outside air from the vehicle via the first exhaust duct; wherein the HVAC device includes a cooling and dehumidifying operation mode and actuation of the compressor and actuation of the first blower creates a third flow path introducing interior air of the vehicle via the vehicle interior air intake duct, supplying the interior air of the vehicle to the evaporator and the dehumidifying member, and back to the vehicle interior via the vehicle interior air reflux duct; and wherein the HVAC device includes the cooling and dehumidifying operation mode and actuation of the second blower creates a fourth flow path introducing outside air via the outside air introduction duct to the condenser and to the second exhaust duct to be exhausted outside the vehicle.
