AIR CONDITIONER AND VENTILATOR FOR CAR

摘要

PURPOSE:To maintain ventilating performance on a high level for a long time by changing the air guided to a car room into the air in which it is heat-exchanged between the air and the air discharged from the car room and making the outside air which passed through a full heat exchanger re-flow into the full geat exchanger. CONSTITUTION:An outside air intake passage 1 whose suction port 1a opens at the position where the travelling wind of a car is received and an inside air intake passage 2 whose suction port 2a opens in the car room are provided so as to be intersected in a single place and a full heat exchanger 3 is arranged at the intersection. Further, the upper location of the full heat exchanger 3 of the inside air passage 2 and the lower location of the full heat exchanger 3 of the outside air passage 1 are connected by the first auxiliary passage 19. Furthermore, the location between the first passage opening section 19a of the inside air passage 2 and the full heat exchanger 3 and the location between the first auxiliary passage opening section 19b of the outside air passage 1 and the full heat exchanger 3 are connected to the second auxiliary passage 20. Besides, the air which passed through the heat exchanger 3 is properly discharged from blowoff ports 10-13 through an evaporator 6 and a heat core 7.
