Abstract

PURPOSE:To improve fuel efficiency with an air conditoner in which a compressor is driven or stopped depending on the temperatue of a vehicle room, by driving the compressor, which remains stopped at the initial stage of starting and acceleration of an engine, when the output of the engine has reached a prescribed level. CONSTITUTION:When the temperature Tr of a vehicle room 12 is detected to be higher than a set level TrST, a clutch 3 is engaged to drive a compressor 1 by an engine 2 to control the temperature of the vehicle room. In that case, if the compressor 1 remains stopped in the initial stage of acceleration of the engine 2 at its starting, the drive of the compressor 1 is not started until the engine output (product of engine's torque and engine's rotational frequency) reaches a set level. As a result, in the initial stage of acceleration at the engine starting with a large rate of increase in the consumption of fuel, the ratio of drive of the compressor 1 is decreased to reduce the fuel consumption.
