ABSTRACT:
The compressor (3) of the refrigerating fluid circuit is driven by the thermal engine (1) of the vehicle when the latter is functioning and, when parked, by the alternator (2). The latter, fed with three-phase current from an auxiliary battery (10) so as to function as a motor, and the compressor (3), are then disconnected from the crankshaft (20) by a free-wheel mechanism (7). The preliminary air conditioning of the vehicle when parked is thus provided without a special electric motor for driving the compressor, with reduced expenditure of energy by virtue of the feeding of the alternator with three-phase current, and without any risk of exhaustion of the main battery by virtue of the auxiliary battery (10).
