The improvement of the coefficient of performance (COP) and the reduction of the chiller size are required for the adsorption chiller. The authors have proposed the dual evaporator type adsorption chiller (DEAC) to improve the cooling perfomrance. The chiller is
consisted of two evaporators and a condenser as well as three adsorbers. The evaporation-adsorption process occurs at two different pressure levels, which results in the extension of
the adsorbate concentration change between the adsorption and the desorption. The experimental study of the dual evaporator type adsorption cycle was performed to reveal the
performance improvement by the DEAC. The improvement of the performance indices due to the two staged evaporation-adsorption was confirmed by experimental measurement. The
COP of the dual evaporator type adsorption chiller was compared with that of the conventional adsorption chiller. The results showed the advantages of the dual evaporator
adsorption chiller over the conventional adsorption chiller.
