Claims (1)

[Scope of utility model registration request] A detection means that detects a physical environmental factor related to temperature and outputs it as an electric signal, a setting means that sends out an electric signal according to a setting operation by a passenger to set the temperature inside the vehicle, and an operation element related to temperature. and an arithmetic control device that performs calculations to create an optimal environment in the vehicle interior based on the output signals of the detection means and the setting means, and sends command signals to the drive apparatus based on the calculation results. In the automatic air conditioner, the detection means includes a water temperature sensor that detects the temperature of engine cooling water, a lower footwell outlet temperature sensor that detects the temperature of the outlet to the footwells, and an upper room temperature sensor that detects the temperature of the upper part of the passenger compartment. the drive device has at least a blowout mode actuator that drives a door that selects an air blowout port, and a motor control circuit that drives a blower motor that controls a blowout air volume; When it is determined to start in heat mode based on the upper room temperature signal output by the sensor, (1) while the water temperature is determined to be lower than the lower limit based on the water temperature signal output from the water temperature sensor; The mode actuator sets the defroster mode, and the motor control circuit sends out a command signal to operate the blower motor at a very low speed; (2) the water temperature is adjusted according to the water temperature signal output from the water temperature sensor; When it is determined that the temperature has increased to the lower limit value, the mode actuator forms a temporal heat mode based on a predetermined rate of change, and the motor control circuit generates a slow heat mode over time based on the predetermined rate of change. (3) After that, when it is determined that the foot outlet temperature has risen to the reference value based on the outlet temperature signal output by the foot outlet temperature sensor, the motor control circuit A starting control device for an auto air conditioner for an automobile, characterized in that it sends a command signal so as to operate according to a control mode.
