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...

Numerical Study on the Design of Microchannel Evaporators for Ejector Refrigeration Cycles

Two-phase ejectors are devices capable of improving the performance of refrigeration and air conditioning cycles by means of expansion work recovery. Ejector studies often focus on the design and performance of the two-phase ejector and the effect it can have on the performance of the ejector cycle. However, the ejector is not the only component of the system that can have a significant influen...

User interface design considerations EESCoolTools - a collection of simulation models for refrigeration applications

When designing a user interface for a simulation model there are several important issues to consider: Who is the target user group, and which a priori information can be expected. What questions do the users want answers to and what questions are answered using a specific model? When developing the user interface of EESCoolTools these issues led to a series of simulation tools each with a spec...

European Supermarket Refrigeration Systems Eco-Efficiency Considerations

Fluorinated hydrocarbon refrigerants have especially in Europe been drawn into the focus of the public debate concerning the background of reducing greenhouse active substances. This debate concentrates mainly on the GWP (Global Warming Potentials) properties of the substances. To step forward from a material based discussion to a useful dialogue about substances in their respective application...
