PURPOSE: An automatic air conditioning unit is provided to simplify a controlling circuit and remote control in a driving room by air-conditioning by using a train controlling unit of an electromotive railroad car. CONSTITUTION: An automatic air conditioning unit comprises temperature perceiving sensors(2,2a), a temperature detector unit(TDU), a selection switch(CHCgS) of an airconditioning unit and a railroad car controlling unit(TIS). The temperature perceiving sensors(2,2a) perceive the temperatures of indoor/outdoor. The temperature detector unit(TDU) transmits the temperature signal inputted from the temperature perceiving sensors(2,2a) to the railroad car controlling unit(TIS) in every 0.5 seconds by using a RS485 which is an indoor/outdoor temperature serial communication link. The selection switch(CHCgS) selects one of the modes of a 1/3 heating, 2/3 heating, ventilation, semi-cooling, total cooling, stop and automatic. The railroad car controlling unit(TIS) outputs airconditioning controlling signals by using the indoor/outdoor temperatures transmitted through the RS485 in every 0.5 seconds. Therefore, the control of airconditioning use the railroad car controlling unit(TIS) instead of a separate controller. |
