Abstract
The Stirling cycle refrigerators, which are the counterparts of the Stirling engines are of gas cycle machines. In the present paper, experimental investigation and numerical analysis of Beta-type Stirling refrigerator for domestic applications are conducted. The refrigeration performances such as input power requirement, cooling power, and coefficient of performance for moderate temperature applications have been analyzed using different working fluids (air, nitrogen, helium, and hydrogen). The numerical analysis is conducted to evaluate the performance of a machine with respect to different operating frequencies and charging pressures. The result of the analysis showed that air and nitrogen have better cooling power than helium and hydrogen in the operating ranges (15–25 bar and 6–12 Hz) of the cooling machine. On the other hand, the coefficient of performances in the case of helium shows a higher rate of increase with charging pressure than that of air and nitrogen.
