ABSTRACT:
A compact apparatus for residential, commercial and industrial airconditioning involving balanced heat recovery ventilation, heating, humidification, dehumidification, cooling and air filtration comprises two treatment vessels, each containing a compact packed bed of a solid sorbent material, a heater and a solid heat exchanging material, a 4-way valve for switching the flows of the exhausted stale air and the incoming fresh air between the two treatment vessels to permit a cyclic countercurrent short cycle operation of the packed beds to achieve efficient transfer of heat and moisture between the two air streams. The two treatment vessels are complemented with a combustor, a direct evaporative cooler and a solid state process controler permitting operation of the apparatus to provide the required services during the winter-heating season, summer-cooling season and the rest of the year-ventilation season to maintain comfort in the air conditioned space. Only a small amount of power is used to operate blowers to maintain the flows of the individual air streams.
