Although caloric refrigeration systems, such as magnetic and elastocaloric ones have shown promising
potential in the last decade, their application in stand-alone applications remains scarce. Namely, they can
provide high COP values and sufficient cooling power but only at a low temperature span between the heat
source and the heat sink. However, the performance of the caloric refrigeration systems drops significantly
at higher temperature spans (above 30 K), which are usually required in most common refrigeration
applications. This work introduces a new concept or future application that matches perfectly with the
current state of development of caloric refrigeration technologies, which is their hybridization with vapour
compression systems (VCS) through subcooling. In subcooling applications, the required temperature span is
low, therefore, the caloric systems can be used to boost the operation of vapour compression refrigeration
systems toward higher efficiencies. Based on experimentally obtained data of different prototypes (magnetic
refrigeration system, elastocaloric refrigeration system and CO2 transcritical refrigeration plant) the energy
results and optimum operating conditions of the hybrid caloric-VCS systems will be presented. [-]
