In recent years, elastocaloric cooling has shown great potential as an alternative to vapor-compression refrigeration. However, there is still no existing device that offers fatigue-resistant operation and yet high cooling/heat-pumping performance. Here, we introduce a new design of regenerator based on compression-loaded Ni-Ti tubes, referred shell-and-tube-like regenerator. Our design, which can operate in both heat-pumping modes, enables durable record performance with maximum temperature...
The elastocaloric cooling, utilizing latent heat associated with martensitic transformation in shape-memory alloys, is being considered the recent years as one of most promising alternatives to vapour compression cooling technology. It can be more efficient and completely harmless environment people. In first part this work, basics effect (eCE) state-of-the-art field materials devices are presented. second part, we addressing crucial challenges designing active regenerators, which currently...
Elastocaloric cooling is emerging as one of the most promising alternatives to vapor-compression technology. It based on elastocaloric effect (eCE) shape memory alloys (SMAs), which occurs due a stress-induced martensitic transformation (superelasticity). In recent years, several proof-of-concept devices have been developed and best them already achieved commercially relevant characteristics. However, proposed are not yet ready for commercialization, mostly their short fatigue life,...
Abstract In recent years, elastocaloric cooling technology has been considered as one of the most promising alternatives to vapor compression technology. Given that is only in early stages development, a uniform method for evaluating effect not yet established, and thermodynamics different cycles have studied detail. Therefore, main goal this work investigate these two important areas. Here, multiple thermodynamic were studied, focusing on parameters holding period cycle, which essential...
Elastocaloric cooling is considered an environmentally friendly future alternative to vapor-compression technology. Recently, a shell-and-tube-like elastocaloric regenerator loaded in compression has demonstrated record-breaking heat-pumping performance and fatigue-resistant operation. The aim of this work thus present new 1D numerical model simulate optimize the operation with design. In first part work, superelastic properties single NiTi tube, which serve as input data for model, were...

Abstract Shape memory alloys such as NiTi can be used recyclable, nontoxic, nonflammable, and environmentally friendly solid refrigerants in elastocaloric cooling/heat-pumping. Thin wires under tension thin- walled tubes compression that allow for fast efficient heat transfer are excellent candidates to applied devices were therefore selected this study. Multiple thermodynamic cycles studied with an emphasis on the parameters of holding period cycle (essential between material sink/source)....
