A simplified mathematical model of a Vuilleumier refrigerator is derived, resulting in a system of four nondimensionalized differential equations. The model considers thermal losses due to a finite heat transfer coefficient between the working fluid and the wall, and to regenerator effectiveness less than unity. Numerical solutions are obtained for operating temperatures that would apply to solar powered space cooling applications. The results show that the coefficient of performance of the Vuilleumier refrigerator is slightly below that of a lithium-bromide/water absorption refrigerator for source temperatures below 100C (212F). At higher source temperatures, the performance of the Vuilleumier refrigerator increases significantly.
