| Abstract: | Mass recovery in activated carbon/ammonia adsorption cycle can play an important role to better the performance of refrigeration cycle. Coefficient of performance might increase or decrease with mass recovery process due to different working conditions. Cooling capacity per kg of adsorbent can be significantly increased with mass recovery process. And the effects of mass recovery do not vary much due to different operating conditions. The effect of mass recovery on cooling capacity does not vary with heat capacity of thermal fluid and bed metal. The higher the condensing temperature is, the more the cooling capacity of mass recovery cycle will be improved. The cycle with mass and heat recovery has a relatively higher COP . 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. |
