Abstract

When a temperature of a coolant is a first predetermined temperature or higher, an air conditioner ECU executes a first control that sets a target evaporation temperature higher by a predetermined temperature and the air conditioner ECU executes a second control that changes the target evaporation temperature in accordance with a cooling load inside the vehicle cabin. When the second control is executed after the first control is executed, the air conditioner ECU sets a first target evaporation temperature set by the first control as the target evaporation temperature, and calculates a second target evaporation temperature that is changed by the second control based on the target evaporation temperature immediately before the first control is executed. When the second target evaporation temperature becomes larger than the first target evaporation temperature, the air conditioner ECU sets the second target evaporation temperature as the target evaporation temperature.
