Abstract: Utilization possibility of Stirling refrigerator with a pulse tube in refrigeration temperature range was analysed and studied. The Performance of Stirling refrigerator with a PUlse tube wascompared to that of pure Stirling refrigerator by the means of experiment. The conclusion that theperformance of Stirling refrigerator with a pulse tube was superior to pure Stirling one in temperaturerange above 245 K was obtained in this paper. The effect Of the orfice and length of the pulse tube onthe Performance of Stirling refrigerator with a pubs tube was abc discussed.
