Efficiency of an open-cycle air conditioning apparatus and method for heating and cooling is improved and the economy of external power is increased both with respect to cost and energy consumption by providing a combination of a primary heater and a secondary heater for heating the regeneration stream for regenerating the desiccant means in the air conditioning apparatus. The thermal source for the primary heater may utilize waste heat or solar energy which is transferred to a solid phase thermal storage means by a gaseous phase heat exchange medium. The thermal energy may be transferred from the thermal storage means to the regeneration stream of the open-cycle air conditioning apparatus either directly by passing the air stream over the solid phase thermal storage means or indirectly by passing liquid in an enclosed system through the solid phase thermal storage means and the regeneration stream.

An open-cycle air conditioning apparatus for heating and cooling comprising: an enclosure defining a treatment air passageway and a separate regenerative air passageway; means for passing an air stream through each of said passageways; a sensible heat exchanger means for transfer of thermal energy from one of said passageways to the other; a desiccant means for transfer of moisture from the air treatment passageway to the regenerative air passageway and spaced toward the exhaust of the regenerative air stream from said heat exchanger means; a first evaporative cooling means near the exit of the conditioned air passageway and a second evaporative cooling means near the entrance of the regenerative air passageway; a first heater means in the regenerative air passageway between said sensible heat exchanger means and said desiccant means supplying heat to the entire regenerative air stream; a second heater means in the regenerative air passageway between said first heater means and said desiccant means supplying regeneration heat to a portion of the regenerative air stream previously heated by said first heater means; and a heat collector means and conduit means providing heat to said first heater means.
