Abstract

The invention is a method of cooling air in a vehicle using a cold storage unit (60) in the refrigeration cycle. The air conditioning system and its cold storage unit is adapted to work according to the operation of the vehicle. The method produces cold in excess to be stored in the cold storage unit (60), using the phase change heating of materials, in at least an operation mode of the system. This cold in excess allows to cool the supply air to the comfort volume, in at least one other operation mode. These charge/discharge of the cold storage unit (60) and the refrigeration cycle associated could correspond to a minimization of consumption criteria of the vehicle, for example, a regenerative braking period and a traction/coasting period, or alternatively, according to the optimization of the variable condenser capacity of the refrigeration cycle.
