Study of a gas-liquid-coupled heat-driven room-temperature thermoacoustic refrigerator with different working gases

•Gas-liquid-coupled thermoacoustic refrigerator is studied for different working gases.•Onset and steady-state characteristics of the system are investigated.•The system using hydrogen offers the lowest onset temperature difference of 13.4 K.•Maximum COP of 0.71 is achieved in thermoacoustic refrige...
