PURPOSE:To promote energy saving by providing a room temperature control device for automobiles, etc., which compares the outside temperature with the upper and lower limits of the room temperature and activates a window opening and closing device and/or a cooler/heater system. CONSTITUTION:Action of a control circuit consisting of logical circuits compares AD converted room temperature Ti with the lower limit TL and the upper limit TH of the room temperature. When it is found out of both limits a closing command is given to a window operating device, and after the closed window is confirmed, a heater, if Ti<TL, or a cooler if Ti>TH, is activated into operation. Next, if AD converted outside temperature To becomes TL<=to<=TH while room temperature is also TL<=Ti<=Tu, and the car has been running for 3min or more with a speed of 80km or less, then a window opening command is issued. By opening or closing the window in compliance with the outside temperature, no wasteful energy is consumed. |
