A temperature adjusting device includes a heat radiation portion and a refrigeration cycle device. The heat radiation portion radiates heat of a target object to outside air. The refrigeration cycle device has a condenser and an evaporator. The condenser condenses a high-pressure refrigerant discharged from a compressor that compresses and discharges a refrigerant. The evaporator evaporates a low-pressure refrigerant pressure-reduced in a pressure reducing portion that reduces a pressure of the high-pressure refrigerant. The condenser radiates heat of the high-pressure refrigerant to at least part of the outside air that has passed through the heat radiation portion. The heat radiation portion radiates the heat of the target object to the outside air before heat of the outside air is absorbed in the condenser.

An HVAC module for an automotive vehicle includes a housing defining an air inlet, an upper front zone outlet, a lower front zone outlet, and a rear zone air outlet. An evaporator and a heater downstream of the evaporator are disposed in the housing. The air inlet of the housing is divided by a first divider into an OSA portion exclusively receiving outside air and a REC portion exclusively receiving recycled air. Each of the evaporator and the heater has a respective OSA portion receiving the outside air and a REC portion receiving the recycled air entering the HVAC module through the inlet. A second divider between the evaporator and the heater directs the outside air from the REC portion of the evaporator to the REC portion of the heater. Two temperature doors control access of separate partial streams of the recycled air from the evaporator to the heater.

There is provided a vehicle air conditioning apparatus capable of saving the installation space of the components equipped in the vehicle and reducing the manufacturing cost, by sharing the heat source in the vehicle.
