General description of ACC system
The automatic air-conditioner is adjusted by sending the signals on executing mechanisms on the basis of calculation of necessary temperature of sucking air at receipt on a computer of the information on the desirable chosen temperature and from each gauge (thermodes of internal and external air, solar gauge, gauge of water temperature, thermode behind evaporator, gauge of the automobile speed), and also processings of entrance signals of various sorts of switches, potentiometers and other gauges.
