PURPOSE:To quickly lower an abnormally high temperature of a passenger room at starting, by providing control means to detect the abnormally high temperature of the passenger room on the basis of a room temperature signal from a room temperature sensor and thereafter detect the fall in the room temperature and instruct the closing of a room open/close section and quick cooling. CONSTITUTION:Information from a room temperature sensor 8, a sensor 9 for the degree of opening of an air mixing damper 6, an external air temperature sensor 10 and a temperature setting unit 11 are applied to a microcomputer 15 through an A/D converter 14 to perform calculation and processing in accordance with a prescribed program to apply a change-over instruction for an internal and external air change-over damper 2, a revolution speed control instruction for a blower motor 3, an opening degree control instruction for the air mixing damper 6 and an operating instruction for a sun roof open/close controller 17. The degree of opening of the air change-over damper 2, the revolution speed of the blower motor 3, the degree of opening of the air mixing damper 6, the closing of a sun roof, etc. are controlled by the instructions. This results in efficiently lowering the abnormally high temperature of a passenger room at starting. |
