Application of Magnetocaloric Heat Pumps in Mobile Air-Conditioning

Torregrosa-Jaime, Barbara; Vasile-Müller, Carmen; Risser, Michel; Muller, Christiane; Corberán, José M.; Payá Herrero, J. (SAE (Society of Automotive Engineers) International, 2013)

[EN] Air-conditioning (AC) is an important sub-system in electric vehicles (EVs). AC is responsible for the highest energy consumption among all the auxiliary systems. As the energy is delivered by the batteries, the power ...
Development and validation of a finite element model for water - CO2 coaxial gas-coolers

Sanchez, D.; Cabello, R.; Llopis, R.; Torrella Alcaraz, Enrique (Elsevier, 2012-05)

The gas-cooler heat exchanger is a characteristic device of the refrigeration plants that use CO2 as the working fluid in transcritical conditions. The proper gas-cooler sizing, allows getting the maximum effectiveness in ...
Energetic evaluation of an internal heat exchanger in a CO2 transcritical refrigeration plant using experimental data

Torrella Alcaraz, Enrique; Sanchez, D.; Llopis, R.; Cabello, R. (ELSEVIER SCI LTD, 2011)

[EN] The performance of an Internal Heat Exchanger (IHX) operating in a CO 2 transcritical refrigeration plant is analysed, from an energetic point of view, in this work. The evaluation is based on experimental data by ...
Heat transfer modelling in honeycomb wall-flow diesel particulate filters

Galindo, José; Serrano Cruz, José Ramón; Piqueras, P.; García Afonso, Óscar (Elsevier, 2012-07)

Heat transfer in wall-flow monoliths has gained in interest because of the widespread adoption of these systems by automotive industry to fulfil soot emission regulations and the importance of heat exchange on the regeneration ...
Impact of classical assumptions in modelling a microchannel gas cooler

Martínez-Ballester, Santiago; Corberán, José M.; Gonzálvez-Maciá, José; Domanski, Piotr A. (Elsevier, 2011)

[EN] Most of the current air-to-refrigerant heat exchanger models use the classic ¿-NTU approach, or some of its assumptions. These models do not account for longitudinal heat conduction in the tube and the fin, and the ...
Improving parameter estimates obtained from thermal response tests: Effect of ambient air temperature variations

Bandos, Tetyana; Montero Reguera, Álvaro Enrique; Fernández de Córdoba Castellá, Pedro José; Urchueguía Schölzel, Javier Fermín (Elsevier, 2011-06)

[EN] This paper presents a method of subtracting the effect of atmospheric conditions from thermal response test (TRT) estimates by using data on the ambient air temperature. The method assesses effective ground thermal ...
