Abstract
An automobile air-conditioning apparatus in which the compressor torque of a variable capacity refrigerant compressor is estimated with improved accuracy. The compressor torque is measured on the basis of (1) high-side pressure of the refrigerating circuit directly influencing the compressor torque and (2) a control current value directly controlling the compressor. The accurately estimated compressor torque is then used to stabilize the speed of the vehicle engine driving the compressor.
