The fins of the evaporator should be cleaned and aligned in order to allow an adequate air flow through the
complete surface, ensuring the correct function of the evaporator, and the consequent energy transfer to the
refrigerant gas.

The alignment of the fins can be done with an adequate brush and the cleaning process, with a vacuum cleaner.

as for air conditioning, which cleans and avoids deposition of dirtiness.
