Résumé

Air-cycle is an alternative thermodynamic approach to vapour compression/adsorption cycles, satisfying cooling & heating needs for industrial and residential processes with zero GWP and zero ODP. This paper presents a one-dimensional analysis of a novel open air-cycle system, incorporating the FeTu™ positive displacement compander, a single spherical two-stage rotor acting both as compressor and expander. The cooling capacity and Coefficient Of Performance (COP) of a small 84mm rotor are simulated over temperature differentials between 0-80˚C and operating speeds 500-3000r/min. The indicated cooling power is 210W at 3000r/min and temperature differential (ΔT) of 80˚C. The study indicates that this single device approach overcomes COP limitations normally associated with conventional air-cycle cooling solutions. Based on 20˚C ambient air inlet temperature, the COP is determined to be 2.5 at ΔT 0˚C, 5 at ΔT 20˚C and 9 at ΔT 40˚C. These simulations characterise the device and demonstrate pre-test performance and feasibility as a cooling/heating solution. A proof of concept test is eventually presented and benchmarked against the model results to outline paths for improvement for the ‘roticulating’ compander.
