The maximum value is increased, and when the outside temperature is low, the minimum value of the temperature of the blown air is increased, and the temperature adjustment damper is adjusted so as to decrease the minimum value as the outside temperature rises. The blower is adjusted so that the amount of air blown out increases as the absolute value of the difference increases.When the temperature of the cooling water is low during the heating operation, the amount of air blown out from the outlet provided at the foot is increased. When the temperature of the cooling water increases, the damper for switching the outlet is adjusted so that the ratio of the amount of air blown from the outlet provided at the foot is reduced, and the evaporator is operated during the cooling operation. When the temperature of the evaporator is high, the amount of air blown from the air outlet is set to zero, and when the temperature of the evaporator falls, the air outlet switching damper is adjusted so as to start the air blow.

A blower that takes in air and blows air into the apparatus, an evaporator that cools the air sent from the blower, a heater that heats a part of the air cooled by the evaporator, and air that is heated by the heater Temperature control damper for adjusting the ratio of the amount of air to the amount of air not heated by the heater,
An outlet for blowing air, at least one
A plurality of outlets provided at the feet, an outlet switching damper for adjusting the ratio of the amount of air blown out from the outlet provided at the feet, a temperature adjusting damper and an outlet switching damper, respectively. An actuator for controlling, an in-vehicle temperature detecting means for detecting an in-vehicle temperature, and an in-vehicle temperature setting means for setting the in-vehicle temperature,
When stable, select whether to perform heating operation or cooling operation according to the outside temperature.When the inside temperature is lower than the set temperature, the temperature of the blown air is increased according to the temperature difference. A function that adjusts the temperature control damper to lower the temperature of the blown air according to the difference, and adjusts the blower to increase the amount of blown air as the absolute value of the difference between the inside temperature and the set temperature increases. An automatic air conditioner for a vehicle having a stable control circuit having a function of selecting whether to perform a heating operation or a cooling operation according to the temperature outside the vehicle at the time of starting, and a maximum temperature of the blown air when the temperature outside the vehicle is high. Lower the temperature, increase the maximum value as the temperature outside the vehicle decreases, raise the temperature of the blown air when the temperature outside the vehicle is low, and lower the temperature of the blown air as the temperature outside the vehicle increases The function of adjusting the damper for temperature adjustment, the function of adjusting the blower to increase the amount of blown air as the absolute value of the difference between the vehicle interior temperature and the set temperature increases, and the temperature of the cooling water during the heating operation When the temperature is low, increase the amount of air blown from the outlet provided at the feet, and blow the air so that the ratio of the amount of air blown from the outlet provided at the feet decreases as the temperature of the cooling water increases. Adjust the mouth-switching damper.When the temperature of the evaporator is high during cooling operation, set the amount of air blown from the outlet to zero, and adjust the outlet-switching damper to start blowing when the temperature of the evaporator falls. An automatic air conditioner for a vehicle, comprising: a start-up control circuit having a function of performing a starting operation.
