Study on heat and mass recovery in adsorption refrigeration cycles

An adsorption air conditioner has been developed and some operation results are summarized. Mass recovery process is proposed to improve the performance. Performance predictions are presented and show that mass recovery can play an important role to better the performance of adsorption refrigeration cycle. Coefficient of performance might be increased or decreased with mass recovery process due to different working conditions. Cooling capacity can be significantly increased with mass recovery process. The cycle with mass and heat recovery has a relatively higher improvement. It can also be seen that the cycle time will be much shorter and it will certainly enhance the cycle with higher cooling/heating power.
