Abstract: The models of absorber and bubble pump in a liquid-desiccant air conditioning system without pump are developted. By simulation, theoretical analysis is given, and their performances are predicted. This investigation gives a theoretical base for the system design. For absorber, the appropriate solution and air mass rate is in a range of 1.0¡«1.5. For bubble pump, it's size is determined by the pressure loss analysis of solution circulation. The gravitational loss shares 79%, and the friction loss 18%. The heat power of bubble pump should be within the range, in which the mass rate of elevated solution and the concentration difference of the generated solution synchronously increase with increasing of the heat power.
