Air conditioning system for an electric transport vehicle supplied by an electrical supply network, the air conditioning system comprising - at least one actuator for the production of heat or cold (3, 8), and - regulating means (6, 6') configured in order to generate at least one operating command (6c, 6c') applied to said at least one actuator (3, 8) as a function of values for parameters representing the climatic conditions (6a, 6a'), said at least one actuator delivering an average power over a predetermined time period, said air conditioning system (1, 1') being configured such that the regulating means are configured in order to generate said at least one operating command (6c, 6c') applied to said at least one actuator (3, 8) as a function moreover of the value for a parameter (6b, 6b,) relating to at least one electric transport vehicle supplied by said electrical supply network, said value for said parameter (6b, 6b') indicating that the electrical energy is consumed by said at least one electric transport vehicle or that electrical energy is produced by said at least one electric vehicle, said at least one operating command (6c, 6c') being generated such that the average power delivered by said at least one actuator (3, 8) over said predetermined time period has substantially the same value as when the regulating means (6, 6') only take into account said parameters representing the climatic conditions (6a, 6a')over the predetermined time period, said at least one operating command (6c, 6c') being generated such that - if during a first period A in which the value for said at least one parameter (6b, 6b') indicates that the electrical energy is consumed by said at least one electric transport vehicle, the average power delivered by said at least one actuator (3, 8) during said first period A is less than the value of the average power during said predetermined time period when only said parameters representing the climatic conditions (6a, 6a') are taken into account for said generation of said operating command (6c, 6c'), and - if during a second period B the value for said at least one parameter indicates that electrical energy is produced by said at least one electric transport vehicle, the average power delivered by said at least one actuator (3, 8) during said second period B is greater than said value of the average power during said predetermined time period when only said parameters representing the climatic conditions (6a, 6a') are taken into account for said generation of said operating command (6c, 6c'), said air conditioning system (1,1'), being characterized in that said at least one parameter (6b, 6b') relating to at least one electric transport vehicle relates to at least one electric transport vehicle supplied by said electrical supply network and different from said electric transport vehicle comprising said air conditioning system (1, 1'). - at least one actuator for the production of heat or cold (3, 8), and - regulating means (6, 6') configured in order to generate at least one operating command (6c, 6c') applied to said at least one actuator (3, 8) as a function of values for parameters representing the climatic conditions (6a, 6a'), said at least one actuator delivering an average power over a predetermined time period, said air conditioning system (1, 1') being configured such that the regulating means are configured in order to generate said at least one operating command (6c, 6c') applied to said at least one actuator (3, 8) as a function moreover of the value for a parameter (6b, 6b,) relating to at least one electric transport vehicle supplied by said electrical supply network, said value for said parameter (6b, 6b') indicating that the electrical energy is consumed by said at least one electric transport vehicle or that electrical energy is produced by said at least one electric vehicle, said at least one operating command (6c, 6c') being generated such that the average power delivered by said at least one actuator (3, 8) over said predetermined time period has substantially the same value as when the regulating means (6, 6') only take into account said parameters representing the climatic conditions (6a, 6a')over the predetermined time period, said at least one operating command (6c, 6c') being generated such that - if during a first period A in which the value for said at least one parameter (6b, 6b') indicates that the electrical energy is consumed by said at least one electric transport vehicle, the average power delivered by said at least one actuator (3, 8) during said first period A is less than the value of the average power during said predetermined time period when only said parameters representing the climatic conditions (6a, 6a') are taken into account for said generation of said operating command (6c, 6c'), and - if during a second period B the value for said at least one parameter indicates that electrical energy is produced by said at least one electric transport vehicle, the average power delivered by said at least one actuator (3, 8) during said second period B is greater than said value of the average power during said predetermined time period when only said parameters representing the climatic conditions (6a, 6a') are taken into account for said generation of said operating command (6c, 6c'), said air conditioning system (1,1'), being characterized in that said at least one parameter (6b, 6b') relating to at least one electric transport vehicle relates to at least one electric transport vehicle supplied by said electrical supply network and different from said electric transport vehicle comprising said air conditioning system (1, 1').
