Patent number: 11518217Abstract: 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.Type: GrantFiled: June 27, 2018Date of Patent: December 6, 2022Assignee: HANON SYSTEMSInventors: Se Won Min, Sang Jun Yoo, Young Min Kim, Chui Soon Kim, Hong Rae Jung, Chang Hyun Baek, Dae Yeop Jeong
