PURPOSE:To enhance the control ability of a secondary air introduction type air-conditioning system, by forming a blow-outport for a secondary air introduction duct, and controlling a damper in association with a control section. CONSTITUTION:A passage for a heater core 14 is opened and closed by means of a mix door 15 through a cable 26 when a temperature lever 24 is manipulated, and primary air introduced through a blow-out air temperature control section 16 is changed over to be delivered into a bypass passage 16 or the heater core 14. In association with the operation of the above-mention mix door 15, a connecting rod 29 actuates a link 28 through a link 27, with this arrangement the link 28 is rotated about a fulcrum 28a, and therefore, a damper 6 opens and closes the blow-out port 4a of the secondary air introduction duct 4. With this arrangement the secondary introduction passage may be opened and closed in association with the control section, thereby it is possible to enhance the control ability of the air-conditioning system by a passenger. |
