PURPOSE:To automate the opening and closing of the air conditioning car roof window by detecting the temperature and humidity in the car room with respective sensors, and controlling the opening and closing of the roof window in response to the detected values. CONSTITUTION:Sensors 7, 8 detect the temperature and humidity of the car room, respectively, and their outputs are inputted into and digitallized by the coding circuits 9, and 10, respectively. Each circuit inputs H signal into the decision circuit 13 in accordance with the range of temperature and humidity information received. The decision circuit 13 decides whether the roof window should by closed, half-opened, or fully opened based on the input information of the range of temperature and humidity, and outputs an operation signal to the cooler 30, and a control signal to the control circuit 32 to perform adequate opening or closing of the roof window. For example, if the car room temperature is 32 deg.C or 32-27 deg.C, and the humidity is 70% or higher, the cooler 30 is operated and the roof window is closed. Full opening is applied when 32-27 deg.C with humidity 70% or less, and a half opening when 17-12 deg.C with humidity 90% or less. Thus, the cooler operation and the roof window are automatically controlled in accordance with the combination of the temperature and humidity providing better comfortableness in the car room. |
