Experimental Study on a Three-bed Two-stage Adsorption Refrigeration Cycle using FAM-Z01 and Z05 Adsorbents

摘要

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