A maintenance and hygiene method and apparatus (50) for a motor vehicle air conditioning system (30) with a cooling circuit (20'). The apparatus comprises a regeneration device (56) and a hygiene device (57) that are integrated in a single body (51) which includes, furthermore, a program means (55) that contemporaneously actuates and controls the regeneration device (56) and the hygiene device (57). The maintenance and hygiene program that is resident in the memory of the microprocessor (55) is then started by an operator. In particular, the hygiene step is carried out contemporaneously with the step of recovering the cooling fluid and with the engine on, and is prolonged up to a lubricating fluid discharging step/establishing vacuum condition step. This way, an important advantage is achieved in terms of operating time and cost reduction, since the operations of regeneration and of hygiene are simultaneously carried out; moreover, the operating space is reduced in comparison with the space needed for the two prior art distinct devices. |
