1. An apparatus for controlling the temperature in the interior of a vehicle, comprising an air duct communicating at one end with the interior of the vehicle for supplying air thereto;

  • cooling means for cooling air flowing through said air duct, said cooling means including a cooler disposed in said air duct;

    a heat exchanger disposed in said air duct adjacent said cooler;

    a tank having therein a fluid capable of storing thermal energy;

    first means for selectively transferring thermal energy between said heat exchanger and said tank, said first means including second means for transferring cooling energy from said heat exchanger to said tank when the fluid temperature in said tank is greater than the air temperature in said air duct near said cooler and the temperature of the interior of the vehicle is less than a first predetermined value, and third means for transferring cooling energy from said tank to said heat exchanger when the fluid temperature in said tank is less than the air temperature in said air duct near said cooler and the speed of an engine of the vehicle is less than a predetermined speed; and

    a housing provided in said air duct and having in an interior thereof a partition wall which divides the interior of said housing into separate first and second portions which respectively serve as said cooler and said heat exchanger, wherein said partition wall is capable of conducting thermal energy and thermal energy passes between said cooler and said heat exchanger through said wall.
