Ventilating, heating and air conditioning auxiliary installation for motor vehicle, has management unit managing operation of auxiliary installation for selecting electrical power supply sources supplying electrical units

摘要

The installation has a set of electrical units (2) supplied with an electrical energy from distinct electric power supply sources (19) e.g. battery (16) and a solar cell (18). A management unit (21) manages the operation of the installation for selecting the power supply sources supplying the electrical units. The management unit cooperates with a detection unit that detects energization of a vehicle. A measurement unit measures exterior and/or interior conditions of the vehicle. The management unit carries out selection between the sources based on the conditions of the vehicle. An independent claim is also included for a method for implementing an auxiliary installation for ventilating, heating and/or air conditioning a passenger compartment of motor vehicle.
