Callaghan Innovation, formerly Industrial Research Ltd, has developed a novel free-piston Stirling cryocooler concept using metal diaphragms. The concept uses a pair of metal diaphragms to seal and suspend the displacer ...

The objective of this research project is to develop a solar-powered refrigerator in the lower capacity range of up to 5 kW of cooling power. With the use of liquid pistons and one of the most efficient thermodynamic cycles ...

The diffusion absorption refrigeration cycle was first identified nearly a century ago but until relatively recently its application had been limited to niche cooling applications such as camping refrigerators. The diffusion ...

A parameter study was carried out on the design variables of a flexure bearing to be used in a Stirling engine with a fixed axial displacement and a fixed outer diameter. A design method was developed in order to assist ...

Air-lift pumps have begun to receive a high degree of attention due to the absence of mechanical components and the potential for their use in renewable energy applications. One of the principal challenges of the air-lift ...

Since 2001, Frauscher Thermal Motors have been conducting research in the field of thermodynamic machines, in particular Stirling engines of various types. One important development step is the invention of a Stirling ...
