A comparative analysis of a CO2 evaporator model using experimental heat transfer correlations and a flow pattern map

Patino, J.; Llopis, R.; Sanchez, D.; Sanz-Kock, C.; Cabello, R.; Torrella Alcaraz, Enrique (Elsevier, 2014-04)

This work analyses and compares two approaches to evaluate the boiling heat transfer of CO2 in a real evaporation process: classical empirical correlations and flow pattern maps. We develop a finite-volume mathematical ...
Evaluation of R448A and R450A as Low-GWP alternatives for R404A and R134a using a micro-fin tubes evaporator model

Mendoza Miranda, Juan Manuel; Mota-Babiloni, Adrián; Navarro Esbri, Joaquin (Elsevier, 2016-04-05)

[EN] When retrofitting new refrigerants in an existing vapour compression system, their adaptation to the heat exchangers is a major concern. R450A and R448A are commercial non-flammable mixtures with low GWP developed to ...
Shell-and-tube evaporator model performance with different two-phase flow heat transfer correlations. Experimental analysis using R134a and R1234yf

Navarro-Esbrí, J.; Molés, Francisco; Peris, Bernardo; Barragan-Cervera, Angel; Mendoza-Miranda, Juan Manuel; Mota-Babiloni, Adrián; Belman Flores, Juan Manuel (Elsevier, 2014)

[EN] This work presents a model of a shell-and-tube evaporator using R1234yf and R134a as working fluids. The model uses the effectiveness-NTU method to predict the evaporation pressure and the refrigerant and secondary ...
