Theoretical Analysis and Performance Testing of a Vuilleumier Refrigerator

Abstract

In this study a Vuilleumier refrigerator is analyzed with thermodynamic modeling Periodic variations in volume mass pressure and temperature in different chambers of the cylinder are predicted The affect of clearance leakage and buffer chamber on the working space are considered A prototype of the Vuilleumier refrigerator is manufactured and the influence of each operating parameter on the cold head temperature in theoretical model is discussed and compared with experiment results The operating parameters include charged pressure rotating speed heating temperature and cooling temperature The refrigerator can reach a no-loading cold head temperature of 221 K at the operating conditions of 16 bar charged pressure 600 rpm rotating speed 900 K heating temperature and 276 K cooling temperature for experiment
