Experimental study on a three-bed two-stage adsorption refrigeration cycle using FAM-Z01 and Z05 adsorbents.

Utilization of the wasted heat is effective to reduce primary energy consumption for mitigating global warming problem. Multistage adsorption refrigeration cycles can be a candidate to utilize low temperature heat sources less than 70 degrees Celsius for air-conditioning. However multistage adsorption cycles have a disadvantage of large volume of the facility due to many adsorption beds, for instance, conventional twostage adsorption chillers have four-beds. This study proposes two-stage adsorption refrigeration cycle with three-beds which reduces one bed in comparison with conventional one. The operation of the cycle is different from that of conventional system as well. To estimate the performance of the proposed cycle using FAM Z01 and Z05. Static analyses on the Dühring diagram was employed to predict the cooling effect. Moreover, the performance of the cycle was investigated experimentally. The results verify that the cycle can work with the hot water of 60 degrees Celsius to produce chilled water of 12 degrees Celsius.
