Journal ArticleDOI
A review of elastocaloric cooling: materials, cycles and system integrations.
Suxin Qian,Suxin Qian,Yunlong Geng,Yi Wang,Jiazhen Ling,Yunho Hwang,Reinhard Radermacher,Ichiro Takeuchi,Jun Cui +8 more
TL;DR: In this article, a comprehensive review of key issues related to achieving a successful elastocaloric cooling system is presented, where the basic and advanced thermodynamic cycles are presented based on analogy from other solid-state cooling technologies.
Journal ArticleDOI
Thermodynamics cycle analysis and numerical modeling of thermoelastic cooling systems
TL;DR: In this paper, the performance of a single-stage cycle with NiTi alloy was evaluated based on a dynamic model developed in this study, and it was found that the system COP was 1.7 for a baseline case considering both driving motor and parasitic pump power consumptions, while COP ranged from 5.2 to 7.7 when estimated with future improvements.
Journal ArticleDOI
Performance enhancement of a compressive thermoelastic cooling system using multi-objective optimization and novel designs
Suxin Qian,Abdullah Alabdulkarem,Jiazhen Ling,Jan Muehlbauer,Yunho Hwang,Reinhard Radermacher,Ichiro Takeuchi +6 more
TL;DR: In this paper, a few novel design options aiming to reduce the cyclic loss were proposed, and a multi-objective optimization problem was formulated and solved using the genetic algorithm to maximize the system capacity and coefficient of performance (COP).
Journal ArticleDOI
Design of a hydraulically driven compressive elastocaloric cooling system
Suxin Qian,Yunlong Geng,Yi Wang,Jan Muehlbauer,Jiazhen Ling,Yunho Hwang,Reinhard Radermacher,Ichiro Takeuchi +7 more
TL;DR: In this article, the design of elastocaloric cooling system driven by hydraulic actuators is presented, where Ni-Ti tubes under axial compressive loading mode are used in the system to provide cooling and heating.
Patent
Solid-state heating or cooling systems, devices, and methods
TL;DR: In this article, the authors describe a system for heating/cooling which includes a plurality of thermoelastic modules, each of which includes one or more structures formed of shape memory alloy, which converts from austenite to martensite upon application of a first stress and release latent heat from the conversion.
