Oil-based thermal energy storage system with solar collector has become populous due to its simple design and characteristics. Majorly, the solar-based thermal storage systems operate between 70 C and 150 C temperature, with one disadvantage of inability to store energy during off-peak hours. The stored energy in thermal storage can be used for the different domestic applications, such as water heating, cooking of food, boiling, etc. An effort has been made to investigate the oil-based thermal energy storage system with the potential design to achieve the higher temperature range of above 200 C. These systems can be used for domestic applications such as cooking. The integrated thermal storage system has been developed using nitrate salt as phase changing material to store the latent heat. The phase change material is filled in the cavity of the oil-based thermal storage. The aluminum oxide (Al 2 O 3 ) and soybean oil nanofluid in a thermo-syphon is used as a heat transfer fluid to store and transfer the sensible heat. Parabolic trough solar collector is coupled with thermal storage system. The maximum temperature of the phase change material, during the experiment, in thermal storage system was achieved up to 220 C, which is the melting point of phase change material. The mathematical model for the heat transfer analysis is also developed and the results were validated with the experimental results. The various heat transfer analysis using regression analysis is discussed.

“…The resulting fluid is a stable mixture of a base-fluid with nanoparticles, called nanofluid, due of enhanced thermal conductivity with respect to the starting base-fluid [30,31]. Nanofluids were presented for the first time to scientific community in 1995 by Choi [32] but, given the revolutionary discovered, they gained much attentions and all over the world scientists started to test nanofluids in the most varied applications [33][34][35][36][37][38][39].…”

Nowadays vapor compression is still the reference technique for heat pumping applications. There are Not-In-Kind heat pumping technologies where a prominent role is occupied by the ones based on solid-state refrigerants, called caloric. The name of such class of technologies comes from caloric effect, manifesting in caloric materials as temperature change due to an applied external field which changes its intensity adiabatically. The reference thermodynamical cycle is called Active Caloric Regenerative heat pump (ACR) cycle and it is applied to a caloric solid-state structure which is both refrigerant and regenerator. The structure is crossed by a Heat Transfer Fluid (HTF) (generally water) that transfers heat from the cold to the hot environment. This paper proposes optimizing solutions as nanofluids for enhancing the heat transfer. The energy performances of a caloric heat pump employing Al2O3-water nanofluids as HTF are evaluated through a 2-D model, for a wide set of caloric materials. The investigation reveals that the addition of nanofluids carries to an upgrade of the energy performances of the heat pump. The best combination occurs if the heat pump works with Ni-Ti (as refrigerant) and alumina-water nanofluid (10 % vol) as HTF.
