An apparatus for controlling the operation of an automobile air conditioner comprises mode switches which permit selection between a manual control mode and an automatic control mode for the control of the flow rate of the conditioned air, and a digital computer incorporating therein a memory which memorizes the selected control mode in accordance with signals received from the mode switches. The digital computer is constituted to give instructions to control members of the air conditioner for controlling in accordance with the values stored in the memory, and to set in the memory a value representing the automatic control mode so as to operate the air conditioner in the automatic control mode when a main switch of the air conditioner is turned on.

Apparatus for controlling operation of automobile air conditioner

A vehicle air conditioner control apparatus for supplying into the passenger compartment of a vehicle a flow of air which is temperature controlled in accordance with air conditioner control conditions, automatically controls an air change-over damper in response to a manual setting device for selectively commanding the induction of outside air, the induction of inside air and the induction of outside and inside air into an air duct and in response to a signal indicative of an absolute temperature of air inducted into the air duct, which is computed and generated in accordance with the outputs of a plurality of sensors.

Air induction control system for vehicle air conditioners

An automotive air conditioner device includes an air duct, a blower motor for producing an air stream to be supplied to an automotive passenger compartment through the air duct, a heat exchanger having a heater and a cooling device, and an electronic control device. The electronic control device includes various sensors, a microcomputer for executing computation processings of output signals from the various sensors in accordance with a predetermined program and producing a first and a second control signal, a drive circuit responsive to the first control signal for changing a temperature adjusting value of the heat exchanger and another drive circuit responsive to the second control signal for changing the cooling power of the cooling device, thereby to control the air temperature within the automotive passenger compartment at a desired value.

Automotive air conditioner having coating power control device

A temperature control method and apparatus responsive to various control conditions to determine the desired amount of temperature control to cause the compartment temperature of a vehicle to approach a desired value. They comprise a first step of producing a first control condition in response to the amount of light incident to the vehicle compartment and a second step of producing a second control condition in response to the amount of heat radiation incident to the vehicle compartment, and a third step whereby the second control condition is adjusted by the first control condition so as to compensate the amount of temperature control in accordance with the adjusted control condition.
