"stabilizes indoor temperatures at 21-22°C in 15 minutes... shape memory alloy elastocaloric effect maximum cooling power 260W, not meeting KW-scale requirement due to difficulty balancing specific refrigerant cooling power with the total active mass; and insufficient heat transfer efficiency during high-frequency operation... overcome using shape memory alloy in series/ fluid in parallel multi-cell, serially connecting 10 elastocaloric cooling units along force application direction, improving heat exchange"
