This invention provides an adaptive optimization method and system for substation building parameters. The method includes: constructing a constraint ontology library of substation building and electrical codes, converting each code clause in the constraint ontology library into a corresponding constraint unit, and assigning an initial weight to each constraint unit; mapping each constraint unit to a corresponding parameter subspace based on an electrical-building association matrix; performing parallel preliminary verification on each constraint unit in the parameter subspace to identify conflicting parameter combinations, tracing the propagation path of the conflict through the electrical-building association matrix, and dynamically adjusting the execution priority of each constraint unit based on the propagation path and the initial weights; and adaptively adjusting the initial building parameters according to the adjusted constraint priority order to generate the corresponding target building parameters. This invention can significantly improve the optimization efficiency of substation building parameters.

An air treatment device for a motor vehicle, for example an ionization device for installation in a motor vehicle air conditioning system, has an air treatment unit by means of which air in the air flow generated by the motor vehicle air conditioning system can be treated, and has a control unit by means of which the air treatment unit can be controlled in accordance with parameters of the motor vehicle air conditioning system in which the air treatment unit is installed. In order to significantly reduce the design expenditure for such an air treatment device, and in particular for its control unit, and in order to create the possibility of using a universal control device as the control unit, it is proposed that the air treatment unit has an electrical coding device which characterizes a variant of the air treatment unit, can be electrically connected to the control unit during assembly of the air treatment unit and the control unit, and can be interrogated by the control unit after the electrical connection to the control unit has been established.
