| Research Abstract |
A desiccant air conditioning system driven by solar energy is proposed, and the absorption performance of two absorbents which can be regenerated at relatively lowtemperatures, i.e. mesoporous silica TMPS 4A and organic sorbent Exran, were experimentally studied. Both the experimental study on the absorption capacity andthe cycle simulation about the energy saving potential by using solar energy for the generation of absorbents were conducted. Based on the experimental measurements ofthe absorption capacity and velocity of the two sorbents, cycle simulation were conducted considering a hybrid desiccant and heat pump air conditioning to controlthe humidity of the room, the solar energy was introduced as alternative energy for generation when available. Cycle simulation results of the hybrid desiccant and heatpump system were compared to that of a conventional cooling dehumidification system, it is shown that the proposed solar heat assisted desiccant air conditioning systemhas 25.1% or 31.9% higher COP when the TMPS4A or Exran is used, respectively.
