PURPOSE:To set cooling capacity of each evaporator to sameness as well as to eliminate a cooling temperature difference between respective supply openings, by setting up the evaporator in a branch connection of a duct after being divided, and connecting each refrigerant pipe line to each of these divided evaporators in parallel, respectively. CONSTITUTION:A duct 13 is extended from the blower 10 set up in a closed section of a body side wall 6 and then it is set up after being branched in Y-shaped form toward each of supply openings 12a and 12b in front and the rear of a car body. And, in a branch connection 13a of the duct 13, there is provided with an evaporator 14. In this case, this evaporator 14 is divided in the same form and miniaturized, and each of these divided evaporators 14a and 14b is set up so as to be conformed to each ventilating surface. Each refrig erant pipe line 15 is connected to these divided evaporators 14a and 14b in parallel. That is to say, each refrigerant pipe line 15 is interconnected to both filler hole and discharge port sides of these divided evaporators 14a and 14b via each of forked branch pipes 16a and 16b. |
