Based on the equation of state of the ideal quantum gas, regenerative characteristics of the quantum Stirling refrigeration cycle is analyzed. The general expression for the coefficient of performance is derived. Under the condition of strong and weak gas degeneracy, the special expressions for the coefficient of performance are discussed. These results will be significant for the research of a Stirling refrigerator in the low temperature range.
