An improved desiccant air conditioning system includes at least one heat exchanging desiccant bed having desiccant material surfaces defining air passageways through the desiccant bed. The desiccant material surfaces adsorb moisture from building air during an adsorption phase and desorb moisture into exhaust air during a desorption phase. The heat exchanging desiccant bed is formed with refrigerant circulating channels or tubes in heat exchange relationship with the desiccant material surfaces. A heat pump system is also provided including an evaporator, compressor, condenser, and metering device operatively coupled by a refrigerant circulating line for evaporation of refrigerant and transfer of heat to the refrigerant from air in the evaporator air passageways during a coincident adsorption/evaporation phase and for condensation of refrigerant and transfer of heat from the refrigerant to air in the condenser air passageways during a coincident desportion/condensation phase. The refrigerant circulating channels are operatively coupled in the refrigerant circulating line of the heat pump system so that the heat exchanging desiccant bed comprises either the evaporator or the condenser or a component element of the evaporator or condenser. Various combinations of desiccant bed elements and heat pump elements are described. A heat pump desiccant bed air conditioning system is also provided by operatively coupling a heat pump between sources of relatively hot and cold heat transfer liquid of a non-change of phase heat transfer liquid circulating heat exchanging desiccant bed.
