F24F3/1429 - CPC Classification

Classification description:

Air-conditioning systems in which conditioned primary air is supplied from one or more central stations to distributing units in the rooms or spaces where it may receive secondary treatment; Apparatus specially designed for such systems characterised by the treatment of the air otherwise than by heating and cooling by humidification; by dehumidification by absorbing or adsorbing water, e.g. using an hygroscopic desiccant alternatively operating a heat exchanger in an absorbing/adsorbing mode and a heat exchanger in a regeneration mode
