Air filter and associated regeneration process

摘要

A regeneration process and associated filter for an air conditioning system in which the filter, of the activated carbon type (FCA) is heated to an elevated temperature such as to cause desorption of unwanted gases previously absorbed by the activated carbon (FCA) and contemporaneously there is established a modest flow of air to carry away and expel these unwanted gases. The procedure further causes drying and sterilisation of the filter.
