PURPOSE:To make a comfortable air-conditioning state settable so speedily, by installing an air quantity operation circuit which calculates a blowoff air quantity upon receiving each output of a room temperature differential operation circuit calculating a difference between desired temperature and room temperature, and a car heat load operation circuit. CONSTITUTION:A microcomputer 30 is inputted with setting temperature by means of a temperature setting part 28, and reading of outside temperature out of an outside temperature sensor 24 and an amount of solar radiation out of a sunbeam sensor 25 takes place, thereby calculating the desired room teperature, and further car inside temperature is read out by a room temperature sensor 23 whereby car heat load is calculated. Thus, voltage of a blower motor 14 is set and a blowoff air quantity is finally determined. Next, doe the temperature setting of blowoff air, the car inside temperature is as well read out, whereby the desired blowoff air temperature is calculated, and further reading of the blowoff temperature takes place, therefore opening operation for a cooling and heating air mixed door 10 takes place on the bais of the required temperature, thus the blowoff temperature is finally set. Ding like this, since the air quantity of blowoff air and temperature can be separately controlled, air- conditioning control in times of cool-down and warm-up can be comfortably performed. |
