A dynamic mathematical model of a shell-and-tube evaporator. Validation with pure and blend refrigerants

Llopis, R.; Cabello, R.; Navarro-Esbrí, J.; Torrella Alcaraz, Enrique (John Wiley & Sons, 2007)

[EN] This work presents a mathematical model of a shell-and-tube evaporator based on mass continuity, energy conservation and heat transfer physical fundamentals. The model is formulated as a control volume combination ...
A simplified model for shell-and-tubes heat exchangers. Practical application

Vera-Garcia, Francisco; Garcia-Cascales, J. R.; Gonzálvez-Maciá, José; Cabello, R.; Llopis, R.; Sanchez, D.; Torrella Alcaraz, Enrique (Elsevier, 2010)

[EN] 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, ...
Comparacion de differentes evaporadores de aletas y tubos en una bomba de calor aire agua trabajando con propano

Marini, Elena (Universitat Politècnica de València, 2022-04-06)

[ES] El evaporador es uno de los puntos mas criticos a la hora de diseñar bombas de calor de forma eficiente ya que un mal funcionamiento de este no solo penaliza el ciclo de refrigerancion desde el punto de vista de ...
Effect of mean void fraction correlations on a shell-and-tube evaporator dynamic model performance

Navarro-Esbrí, J.; Milián Sánchez, Víctor; Mota Babiloni, Adrián; Molés Ribera, Francisco; Verdú Martín, Gumersindo Jesús (Taylor & Francis, 2015-10-03)

In this paper, the influence of different mean void fraction correlations on a shell-and-tube evaporator dynamic model performance has been evaluated. The model proposed is based on the moving boundary approach and includes ...
Estudio de la formación y crecimiento de la escarcha en evaporadores de tubos y aletas para bombas de calor Aire-Agua

Alarcón Gallén, David (Universitat Politècnica de València, 2022-11-03)

[ES] El fenómeno de la aparición, el crecimiento y la acumulación de la escarcha penaliza el funcionamiento eficiente de una bomba de calor aerotérmica entorpeciendo la transferencia de calor entre el aire y el refrigerante, ...
Estudio experimental de optimización de una bomba de calor agua-agua empleando propano como fluido de trabajo

Martínez Galván, Israel Octavio (Universitat Politècnica de València, 2008-10-13)

La tesis que a continuación se presenta surge como una respuesta práctica al problema medioambiental relacionado con el empleo de sustancias sintéticas como fluidos de trabajo en muchos de los equipos de climatización ...
Experimental characterization of the refrigerant distribution along a finned tubes heat exchanger

Sánchez-Moreno-Giner, Luis; López-Juárez, Emilio; López-Navarro, Alejandro; Gonzálvez-Maciá, José (Universidad de Castilla-La Mancha José Antonio Almendros Ibáñez, 2019-06-14)

[EN] According to the European Commission, heating, cooling and domestic hot water (DHW) production imply 79% of the total energy consumed in households. Moreover, as 84% of this energy is still generated from fossil fuels, ...
Refrigerant maldistribution in brazed plate heat exchanger evaporators. Part B: Analysis of the influence of maldistribution on the evaporator performance

Navarro-Peris, Emilio; Álvarez-Piñeiro, Lucas; Schnabel, Lena; Corberán, José M. (Elsevier, 2021-11)

[EN] The maldistribution of the refrigerant mass flowrate among the different channels of a brazed plate heat exchanger evaporator with distributor, has been studied with a thermographic camera working under different ...
