[EN] 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 ...
The aim of the present paper is to describe a general methodology suitable for analysing any intermediate configuration considered in staged vapour compression refrigeration cycles. This general methodology only depends ...
[EN] Based on a previously developed and validated steady-state model of a single-stage vapour compression plant, the present paper describes an in-depth study directed to examine the consequences of changes in the operating ...
[EN] This work presents the experimental evaluation of the energy efficiency and optimal gas-cooler pressures of a single-stage refrigerating plant working with carbon dioxide as refrigerant in transcritical conditions. ...
The paper presents the analysis of the energy performance of an air vortex cooling tube under variations of the
air inlet properties, with three independent experimental tests validated through the energy balance in the ...
[EN] The aim of the present paper is to detail an analysis, based on experimental data, of the inter-stage working conditions of a two-stage vapour compression facility equipped with a compound compressor, which operates ...
[EN] This work evaluates, from an energetic point of view. the effects of the superheat caused in the refrigerant by the electric motor cooling (SHsc) in a semihermetic compressor installed in an experimental refrigerating ...
[ES] El objetivo delt rabajo es presentar una revisión de las máquinas frigoríficas tritérmicas de adsorción, con mención especial en las que trabajan con la mezcla silicagel (o gel de sílice)-agua. La estructura seguida ...
[EN] A new interactive tool for supporting practical learning in the educational field of refrigeration is presented in this paper. The application, called REFLAB, is used for on-line representation of the main operating ...
