| 1. An air conditioning system for a vehicle comprising:
a temperature switch for setting a desired temperature;
an air-conditioning unit having a blower device for blowing air into a passenger compartment of the vehicle, the air-conditioning
unit further having an evaporator and a heater core for carrying out an air-conditioning operation so as to control temperature
of the air blown into the passenger compartment;
a no-contact temperature sensor for detecting surface temperature of the passenger's clothing; and
a control unit for calculating a target value for temperature of the air blown into the passenger compartment from the air-conditioning
unit, the target value being calculated based on the desired temperature and the surface temperature detected by the no-contact
temperature sensor so that the air-conditioning operation is carried out by the air-conditioning unit in accordance with the
target value,
wherein the air-conditioning unit continues operation using a time delay before returning to normal operation in such a manner
that the time delay in a case of a passenger getting into the vehicle is made larger than the time delay before the passenger
gets into the vehicle.
