Design Considerations for Refrigeration Cycles

Analysis Of Elastomer Refrigeration Cycles

Refrigeration effects can be obtained from elastomers classified as “ideal rubber” by operating over a cycle similar to that of the Carnot cycle. The interesting properties of ideal rubber have long been recognized, with most investigations of potential thermodynamic cycles devoted to power cycles. This paper focuses on the development of refrigeration cycles constructed from ideal rubber refri...

The energy and exergy analysis of a novel cogeneration organic Rankine power and two-stage compression refrigeration cycle

The energy crisis in recent years has led to the use of thermodynamic cycles that work based on renewable energies. Low-temperature cycles—such as organic cycles—are suitable strategies for the application of renewable energies. The present study proposes a novel cycle through the integration of a two-stage compression refrigeration cycle with a combined Rankine power and ejector refrigerat...

Operational optimisation of centrifugal compressors in multilevel refrigeration cycles

Low-temperature energy systems are processes that require cooling at temperatures below ambient, which are accomplished using refrigeration cycles. Little research has addressed the operational optimisation of refrigeration cycles considering the performance of existing equipment. This work develops a methodology for operational optimisation of refrigerated processes, taking into account existi...

The Application Of Vortex Tubes to Refrigeration Cycles

The vortex tube is a structurally simple device with no moving parts that is capable of separating a highpressure flow into two lower pressure flows with different energies, usually manifested as a difference in temperatures. The vortex tube is relatively inefficient as a stand-alone cooling device but it may become an important component of a refrigeration system when employed as an alternativ...
