Energies, Vol 13, Iss 3, p 562 (2020)

The rising of the global energy demand requires the use of alternative energy conversion systems employing renewable sources. In the refrigeration and air conditioning fields, heat driven ejector systems represent a promising way to produce the cooli

Flow boiling data of R452A

Autor: G. Lillo, L. Viscito, Alfonso William Mauro, Rita Mastrullo

Publikováno v: Energy Procedia. 148:1034-1041

Flow boiling pressure drop and heat transfer performance of R452A in horizontal single tubes have not been investigated or reported yet in scientific literature. In this paper, local heat transfer coefficient and pressure gradient for R452A are exper

Waste Heat Driven Multi-Ejector Cooling Systems: Optimization of Design at Partial Load; Seasonal Performance and Cost Evaluation

Autor: Alfonso William Mauro, L. Viscito, Giovanni Napoli, G. Lillo

Publikováno v: Energies, Vol 14, Iss 5663, p 5663 (2021)
Energies; Volume 14; Issue 18; Pages: 5663

In this paper, a seasonal performance analysis of a hybrid ejector cooling system is carried-out, by considering a multi-ejector pack as expansion device. A 20 kW ejector-based chiller was sized to obtain the optimal tradeoff between performance and

Relative importance of entrained liquid fraction and mass transfer at the interface on pressure drop of annular flows

Autor: Rita Mastrullo, Alfonso William Mauro, G. Lillo, Rémi Revellin

Publikováno v: Journal of Physics: Conference Series
Journal of Physics: Conference Series, IOP Publishing, 2019, 1224, pp.012042. ⟨10.1088/1742-6596/1224/1/012042⟩

Flow boiling of R1233zd(E) in a horizontal tube: Experiments, assessment and correlation for asymmetric annular flow

Autor: Rita Mastrullo, Alfonso William Mauro, L. Viscito, G. Lillo

Flow boiling heat transfer and dry-out vapor quality data for the low-GWP refrigerant R1233zd(E) are presented in this paper. Tests have been performed in a single horizontal stainless steel tube with an internal diameter of 6.0 mm for the whole rang

Experimental thermal and hydraulic characterization of R448A and comparison with R404A during flow boiling

Autor: L. Viscito, G. Lillo, Rita Mastrullo, Alfonso William Mauro, F. Pelella

Refrigerant R404A is going to be banned in Europe for different applications due to its very high GWP of 3943. R448A is a suitable alternative (GWP of 1390) among other new mixtures, and is thus receiving considerable attention in literature. However
