Elastocaloric refrigeration technology is considered one of the most promising new high-efficiency refrigeration technologies for replacing conventional vapor compression technology

owing to its high refrigeration efficiency and specific refrigeration power. This paper analyzes and discusses the thermodynamic basis

dynamic theory

materials

and refrigeration cycle as a reference for investigations of the elastocaloric effect of rubber. According to the literature

natural rubber features the best elastic and thermal properties

with a strain of 600% at 0 °C and a maximum temperature change of 12 K. Twisting natural rubber results in a higher temperature change and can reduce the volume of the refrigeration system. When the strain is 300%

the maximum temperature change is 12.9 K

which is 5.4 times that of the untwisted rubber. Theoretical studies regarding the elastocaloric effect of rubber are relatively mature; however

the development of cooling prototype is limited. Further development is required to promote the practical application of elastocaloric refrigeration technology using natural rubber as the working medium. Thus

it is possible to claim that using natural rubber in elastocaloric refrigeration technology is promising.
