Impact of lubricant in the performance of variable speed heat pumps working with R290

Ossorio-Santiago, Rubén Josep; Navarro-Peris, Emilio; Barta, Riley B. (Elsevier, 2022-11)

[EN] Modulating the speed of the compressors and adapting its capacity to the required load has led to a decrease in the annual energy consumption in many applications. However, in the compressor, having adequate lubrication ...
Influence of the number of injections on piston heat rejection under low temperature combustion conditions in an optical compression-ignition engine

Tanov, Slavey; Salvador-Iborra, Josep; Andersson, Öivind; Olmeda, P.; García Martínez, Antonio (Elsevier, 2017-12-01)

[EN] New combustion concepts are being investigated to develop cleaner engines. One of the most promising is partially premixed combustion. The mechanisms of this combustion mode and its impact on performance and emissions ...
Inverse solution to the heat transfer coeffcient for the oxidized ARMCO steel plate cooling by the air nozzle from high temperature

Jasiewicz, Kamil; Malinowski, Zbigniew; Cebo-Rudnicka, Agnieszka (Editorial Universitat Politècnica de València, 2022-05-11)

[EN] The inverse solution tests have been performed to the experimental data obtained during the oxidised Armco steel plate cooling by the air nozzle. The three-dimensional numerical model of heat transfer during the plate ...
Modelling of Heat Pumps Working with Variable-Speed Compressors

Ossorio Santiago, Rubén Josep (Universitat Politècnica de València, 2024-08-06)

[ES] La tecnología de bombas de calor se ha vuelto estratégica en Europa, está extendiéndose rápidamente y se planea que reemplace las calderas de gas en un futuro cercano. Sin embargo, aún enfrenta desafíos, como encontrar ...
