A dynamic model of a shell-and-tube condenser operating in a vapour compression refrigeration plant
Elsevier (2008)This work presents a mathematical model of a shell-and-tube condenser based on mass continuity, energy conservation and heat transfer physical fundamentals, whose methodology can be easily adapted for modelling any type ... -
A simplified model for shell-and-tubes heat exchangers: Practical application
Elsevier (2010)In this paper, a simplified model for the study of shell-and-tubes heat exchangers (HXs) is proposed. The model aims to agree with the HXs when they are working as condensers or evaporators. Despite its simplicity, the ... -
Dynamic model of a shell-and-tube condenser. Analysis of the mean void fraction correlation influence on the model performance
Elsevier (2013)A moving-boundary dynamic model of a shell-and-tube condenser is presented. Within this approach, the mean void fraction is a relevant parameter which is obtained, in this work, using different correlations proposed in the ... -
Energetic evaluation of a CO2 refrigeration plant working in supercritical and subcritical conditions
Elsevier (2014-05)Unlike other refrigerants, R744 (or carbon dioxide) has a very low critical temperature (30.98 °C) which hampers working in subcritical conditions especially when the environment is used as a heat rejection sink. Accordingly, ...
