摘要：A dual type air conditioner for a vehicle is provided to improve the heating efficiency by controlling introducing/discharging cooling water amounts of a rear heater core by a solenoid valve and a backflow preventing door respectively mounted to cooling water inlet/outlet pipes of the rear heater core. A dual type air conditioner for a vehicle includes a temperature sensor mounted at a cooling water inlet pipe of a front heater core for measuring the temperature of cooling water, and a solenoid valve(42) mounted to a cooling water inlet pipe(41) of a rear heater core for opening or closing the inside of this pipe. A control part controls the operation of the solenoid valve according to the temperature measured by the temperature sensor. A backflow preventing door(44) is mounted to the cooling water outlet pipe(43) of the rear heater core for preventing the backflow of the cooling water.
