“…Many are the models developed and published in open literature; most of them are one-dimensional [34]. Cirillo et al [35,36] realized a two-dimensional tool of a single bunch of EC wires based on finite-element method able to reproduce step by step the velocity and the pressure field of fluid, to predict more accurately the solid-to-fluid heat exchange. Through this tool the aspects related to the optimization of the frequency of the AeR cycle, the fluid velocity, the distance between two EC wires and their length were investigated.…”

Elastocaloric is a technology to the class of solid-state cooling based on caloric-effects have attracted great interest in recent years, representing a new and viable alternative to vapour-compression. The physical phenomenon on which elastocaloric systems are based is elastocaloric effect: a physical-thermal phenomenon manifesting in some materials called shape memory alloys where, consequently to an adiabatic variation of the intensity of an external field, a temperature variation (ΔTad), occurs. If the intensity of the field is increasing, a temperature rise is observed in the elastocaloric material; conversely, to a decreasing intensity a temperature fall corresponds. Controlling the temperature of electronic equipment is also essential and, currently, there are not elastocaloric devices specifically addressed to this application. In this context CHECK TEMPERATURE (acronym of “Controlling the Heating of Electronic Circuits: a Key-approach Through Elastocaloric Materials in a Prototype Employing them as Refrigerants of an AcTive Ultrasmall Refrigerator”) project was born: the main purpose of this project is to develop an elastocaloric device targeted on miniature scale for environmentally friendly cooling of electronic components. In this paper all the aspect concerning the development are described.

“…The caloric effect is divided into two types depending on the applied external field. If the external field is generated due to mechanical stress, such as compression [47], tension [48], or torsion [49], it is called the elastocaloric effect [50,51]. This effect occurs in specific materials known as shape memory alloys [52][53][54].…”

In this paper, the application of solid-state cooling based on the barocaloric effect in the cold food supply chain is investigated. Barocaloric solid-state technology is applied to the final links of the cold food supply chain regarding the steps of retail and domestic conservation. In this context, effective barocaloric cooling entails the refrigeration of food at 5 °C (273 K) and as such is a promising cooling technology due to its energy efficiency and environmental friendliness. The categories of food involved in this investigation are meat and fresh food products like soft cheese, yogurt, and milk. The energy performance of the barocaloric system is analyzed and compared with a commercial vapor compression refrigerator of a similar size, both operating using R600a under the same working conditions. Based on the results of this comparison, it is concluded that barocaloric cooling is a favorable technology for application in the final links of the cold food supply chain if the system operates in an ABR cycle at frequencies between 1.25 and 1.50 Hz with a regenerator comprising acetoxy silicone rubber as the solid-state refrigerant and a 50%EG–50% water mixture as the heat transfer fluid flowing at an optimal velocity of 0.15 m s−1. Thus, an appropriate tradeoff between the temperature span, cooling power, and coefficient of performance is guaranteed. Under these conditions, the barocaloric system outperforms the domestic vapor compression cooler operating using R600a.
