Abstract:
1. An air conditioner for a vehicle, comprising: an air conditioning unit for blowing conditioned air to a passenger compartment of the vehicle; at least one seat air conditioning unit for controlling temperatures of seats of the vehicle; a compartment heat-load detecting device for detecting heat loads of the passenger compartment and outputting detection values corresponding to the heat loads of the passenger compartment; a seat heat-load detecting device, by which heat loads of the seat is detected, the seat heat-load detecting device outputting detection values corresponding to the heat loads of the seat; a compartment temperature setting unit, through which a compartment setting temperature of the passenger compartment is set by a passenger; and a control unit, by which air conditioning controls of the air conditioning unit and the seat air conditioning unit are performed and introduced into a steady state from a transient state responding to the detection values of the heat loads of the passenger compartment, wherein: the control unit includes a target blowing-out temperature calculation unit and a seat target blowing-out temperature calculation unit, the target blowing-out temperature calculation unit calculating a target blowing-out temperature of the temperature-conditioned air based on the detection values of the heat loads of the passenger compartment and the compartment setting temperature, the seat target blowing-out temperature calculation unit calculating a seat target blowing-out temperature of the seat based on at least the target blowing-out temperature and one of the detection values of the heat loads of the seat; and in a calculation of the seat target blowing-out temperature by the seat target blowing-out temperature calculation unit, the seat target blowing-out temperature is more influenced by the target blowing-out temperature when a value indicating a degree of the transient state indicates that the air conditioning control more deviates from the steady state.
