Abstract

The performance of a two-stage adsorption chiller with different mass allocation between upper and bottom beds has been investigated numerically. It is found that the chiller can be driven effectively by the waste heat of temperature 55 °C with the heat sink at environment temperature. Results show that cooling capacity can be improved with the optimum allocation of adsorbent mass to the bottom beds than that to the upper beds. The improvement in Coefficient of Performance (COP) values, however, is less significant. It is also seen that the improvement in cooling capacity is more significant for the relatively higher heat source temperature. It is shown that the cooling capacity can be improved up to 20% if the heat source temperature is 80 °C and the average outlet temperature is fixed at 7 °C.
