PURPOSE:To prevent circumstance in a compartment from varying due to the opening a window or the like by storing temperature in a compartment to controllably set temperature stored in opening the window to dummy temperature on the basis of internal air temperature change in opening the window. CONSTITUTION:Internal air temperature TR from an internal temperature sensor 27 is stored successively in a memory means 33. On the other hand, since temperature in a compartment is varied when a window is opened, a temperature change detecting means 34 detects a sudden change point P of said temperature TR to generate the signal B1. A selecting means 28 is controlled by a holding control means 36 to send the sudden change output of the memory means 33 as dummy temperature T1 to the input of a control means 28 for controlling air conditioning elements 5, 24 with the dummy temperature T1. When the window is closed, the internal air temperature similarly generates dummy temperature T2 on the basis of the sudden change point Q detecting signal B2 to control with the dummy temperature T2. By this constitution the sudden change in the atmosphere in compartment is prevented. |
