Abstract

A motor-vehicle is equipped with an auxiliary refrigeration circuit (F') with an electrically-operated compressor (C') of reduced size and power compared to the compressor (C) of the main refrigeration circuit (F). An air guide duct (2) which drives a flow of air towards the passenger compartment of the motor-vehicle includes an auxiliary inlet portion (201) - arranged upstream of the main portion (200) - which contains the evaporator (E') of the auxiliary refrigeration circuit. The vehicle comprises one or more electronic control circuits programmed to activate a refrigeration mode and a heating mode of the passenger compartment when the motor-vehicle is parked with the engine off, even with the driver outside the vehicle. In this operating mode, the auxiliary circuit is active and the flow of air towards the passenger compartment is cooled by passing through the evaporator (E') of the auxiliary refrigeration circuit (F'), or is heated by using the heat generated by the condenser (D') of the auxiliary refrigeration circuit. The electronic control circuits are programmed to also activate a ventilation mode of the passenger compartment, which comprises controlling at least partial opening of one or more windows of the motor-vehicle and the opening of one or more communication valves (101) of the passenger compartment with the external environment, to generate the natural circulation of air from the bottom upwards through the passenger compartment. The cooling, heating and ventilation modes can be controlled by the user by means of an electronic interface device such as a smart-phone, a tablet or the like.
