脉管型斯特林制冷机的能量方程推导及性能分析

Energy Equation Deduction and Performance Analysis of Stirling Refrigerator with a Pulse Tube

通过对脉管型斯特林制冷机的分析和讨论，提出了此类制冷机的物理模型，对能量方程进行了推导，并编制了程序。计算结果显示，脉管型斯特林制冷机在较高的制冷温区比单纯的斯特林制冷机有更大的制冷系数和更高的制冷量。

A physical model of Stirling refrigerator with a pulse tube is presented by means of analysis and discussion. Energy equation is also deduced in this paper. A calculation program to this refrigerator has been constructed. Calculation results show that the performance of Stirling refrigerator with a pulse tube is superior to that of pure Stirling one in a higher refrigeration temperature range.
