Abstract

The pressure wave refrigerators (PWR) have many potential applications due to the simple structure and robustness, if their efficiency becomes competitive with the existing alternative devices. A new compact PWR has been designed and manufactured at the Shock Wave Research Center, the Institute of Fluid Science, Tohoku University. The performance of this PWR was investigated relative to major operation parameters, such as the rotational speed of gas distributor, the length of expansion tubes, the input gas pressure. The maximum temperature decrease of 20°C has been obtained. Some theoretical considerations to improve the PWR efficiency are also given.
