New types of thermoacoustic refrigerators have been developed. It has been reported that the pressure and velocity amplitudes and the heat transferred by sound waves are considerably improved when two thermoacoustic sound wave generators are joined together at their open ends, compared with those of independently operated generators. From a practical point of view, when two thermoacoustic refrigerators are joined together at their open ends, it is expected that the refrigeration performance will be improved compared with that of independently operated ones. The effects of temperature and the flow rate of cooling water in the heat exchanger of the refrigerator on the refrigeration performance are also confirmed.
