Abstract
Abstract A water producing-air conditioning system comprises a water producing apparatus which adsorbs moisture in the ambient air on an adsorbent or absorbent and evaporates water adsorbed on the adsorbent or absorbent by heating it and condenses steam to obtain water; a heat-exchanger which heat-exchange the ambient air with a hot dry air discharged from said water producing apparatus during adsorbing moisture on the adsorbent or absorbent; and an evaporation-cooling apparatus for forming a cold wet air by evaporating water and cooling it by contacting water with a dry air at the ambient temperature passed through said heat-exchanger. The hot air heated by said heat-exchanger or the cold air obtained from said evaporation-cooling apparatus is utilized for the air conditioning. The system can be used for comfortable living in a severe condition such as a desert by the effective combination of the evaporation-cooling apparatus with the water producing apparatus under utilizing heat-exchange in high efficiency.
