A thermodynamic model based on exergy flow for analysis and optimization of pulse tube refrigerators

Cryogenics. 47:166-173
A thermodynamic model based on exergy flow through pulse tube refrigerators (PTRs) is developed. An exergetic efficiency parameter representing the losses in the pulse tube itself is proposed. The effects of control parameters representing a general

This paper describes progress towards the development of a large‐capacity, single‐stage, Stirling‐type, pulse‐tube refrigerator (PTR) for high temperature superconducting power applications. Specifically, the design and fabrication of an expe

Future space‐based systems will require long‐life, active cryocoolers capable of achieving sub‐10 K load temperatures. Currently, the available cryocooler technology at these temperatures is too massive and inefficient. In many cases, reliabili

Rational bases for performance evaluation of cryocoolers are second law and exergy analyses. In this study, a model is proposed for the calculation of energy and exergy flow in an Orifice Pulse Tube Refrigerator (OPTR). Using a needle valve, it can b

Exergy flow in Orifice Pulse Tube Refrigerators (OPTR) is investigated. Input power to the compressor provides the source of exergy and the input exergy’s magnitude diminishes as working fluid passes through each component. The exergy destruction i

The power‐efficiency diagram is a simple and convenient tool to characterize the performance of energy systems. In exergy analysis, the power and efficiency can be represented by the rate of exergy transfer to the cold reservoir and the exergetic e
