Regeneration refrigerators operate with oscillating pressures and flows. Such refrigerators include the Stirling, Gifford-McMahon, and pulse tube refrigerators. This book chapter introduces the thermodynamics for analyzing such refrigeration systems. The concept of time-averaging thermodynamic quantities such as enthalpy, entropy, exergy, and acoustic power over a full cycle is introduced. These time-averaged quantities are then used in the normal first and second laws of thermodynamics to derive the relationships between refrigeration power, power input, and thermodynamic properties of the working fluid. The chapter also deals with energy flows in these refrigerators and sources of losses. Some comparisons are made between the various cycles in terms of their efficiencies.
