PURPOSE:To make air conditioning efficient by setting the intake pressure of a compressor in response to the adjustment state of one of a temperature adjusting means and a blowout mode adjusting means and the transfer state of a fan air quantity transferring means. CONSTITUTION:An intake pressure controller 17 contains an intake pressure setter, with its resistance value changed in response to the position of a temperature adjusting lever 28. The intake pressure of a compressor 8 is set in response to the blast quantity transfer state of a fan 5 by a fan lever 26 and the state of an air mix door 18 by a temperature adjusting lever 28. The current quantity to a pressure control valve 16 is controlled, the communicating port between the intake chamber and the crank chamber of a compressor 8 is opened or closed to control the intake pressure. According to this constitution, the capacity of the compressor is controlled delicately, and air conditioning can be made efficient. |
