Abstract
An automotive air conditioner which conditions air making use of radiation of heat of a condenser and absorption of heat of an evaporator effectively. The evaporator 207 and the condenser 203 are disposed in a duct 100. An condenser disposed in a duct has a heat exchanging section in which heat exchange is performed between refrigerant and draft air. The heat exchanging section is divided into an upper stream area portion, a middle stream area portion and a lower stream area portion, and a temperature sensitive tube of a subcooling control valve is held in contact with a refrigerant passageway which interconnects the middle and lower stream area portions. The subcooling control valve adjusts the opening of a throttle portion thereof so that the subcooling degree on the upstream of the lower stream area portion where the temperature sensitive tube contacts may be a predetermined value (2.degree. to 10.degree. C.).
