The objectives of the present work is describes the analysis, design and an experimental working model of two stage pulse tube refrigerator. By using the Experiment set-up cooling Behavior of the refrigeration system and refrigeration power have been investigate. A minimum temperature of 233.1K at 15.36 W refrigeration power achieved by this two stage pulse tube refrigerator with the system pressure of 7 bar (Abs) and operating frequency of 2.Hz. The 1st stage cold head reaches a lowest temperature of 255.4 K after 220 min and the 2nd stage cold head attains 233.4 K after about 200 min.

Abstract:

The objectives of the present work is describes the analysis, design and an experimental working model of two stage pulse tube refrigerator. By using the Experiment set-up cooling Behavior of the refrigeration system and refrigeration power have been investigate. A minimum temperature of 233.1K at 15.36 W refrigeration power achieved by this two stage pulse tube refrigerator with the system pressure of 7 bar (Abs) and operating frequency of 2.Hz. The 1st stage cold head reaches a lowest temperature of 255.4 K after 220 min and the 2nd stage cold head attains 233.4 K after about 200 min.
