摘要： An air conditioner for a vehicle includes an air conditioning case having a first air passageway and a second air passageway partitioned by a separator therein; a PTC heater disposed in each of the first air passageway and the second air passageway to generate heat by electric energy; and a control unit for controlling operation of the PTC heater. The control unit individually controls discharge temperature of the first air passageway and discharge temperature of the second air passageway of the PTC heater, and if target discharge temperature of the first air passageway and target discharge temperature of the second air passageway are different from each other, the control unit calculates and outputs a compensation value for the PTC heater output of at least one of the first air passageway and the second air passageway. The PTC heater therefore has a reduced output when controlling for dual temperatures.

摘要： The present invention relates to an air conditioner for a vehicle and a control method thereof, which can calculate the range of discharge temperature to the interior of the vehicle, set the upper limit of the discharge temperature, and control the degree of opening of a temp door such that the discharge temperature to the interior of the vehicle gets lower than the upper limit, thereby preventing air of discharge temperature above the upper limit from being discharged to the interior of the vehicle and preventing displeasure or personal injury that may be caused when air of high temperature is discharged.

摘要： An air conditioning system for hybrid vehicles includes: a heater core receiving engine cooling water from an engine and heat an air blown into a vehicle room; an electric water pump pumping the engine cooling water through the heater core when a motor vehicle is switched from an engine drive mode to a motor drive mode; a discharged air temperature sensing unit sensing a discharged air temperature as a temperature of an air discharged into the vehicle room; and a control unit when the motor vehicle is switched from the engine drive mode to the motor drive mode differentially controls a rotational speed of the electric water pump depending on a temperature difference between the discharged air temperature inputted from the discharged air temperature sensing unit and a target discharge temperature calculated in advance based on internal/external temperature conditions and a user set temperature.
