Design of a Microscale Refrigeration System for Optimizing the Usable Space in Compact Refrigerators
(MDPI, 2022-01-24)
This research aims to enter the miniature refrigeration machine sector with the objective of designing a small scale unit while maintaining a competitive coefficient of performance (COP), comparing with a Peltier plates ...
Evaluation of the Thermal Performance of Two Passive Facade System Solutions for Sustainable Development
(MDPI, 2023-12-11)
Sustainable development is essential for the future of the planet. Using passive elements, like ventilated facades based on insulation and air chambers, or living walls, which are solutions based on nature, is a powerful ...
Consideration of the interactions between the reaction zones in the new extended Eddy dissipation concept model
(Elsevier, 2022-01)
The latest Direct Numerical Simulation (DNS) modeling results in flameless combustion suggest interactions between the combustion reaction zones. The New Extended Eddy Dissipation Concept (NE-EDC) model, where model ...
New extended eddy dissipation concept model for flameless combustion in furnaces
(Elsevier, 2020-10-01)
Flameless combustion, also called MILD combustion (Moderate or Intense Low Oxygen Dilution), is a technology that reduces NOx emissions and improves combustion efficiency. Appropriate turbulence-chemistry interaction models ...
Numerical model for liquid-to-liquid heat pumps implementing switching mode
(Elsevier, 2019-09-01)
Residential reversible liquid-to-liquid heat pump systems are effective systems to increase energy efficiency and decrease gas emissions of buildings that can supply both the cooling and heating demand of a building due ...
Mathematical development of an average method for estimating the reduction of the Heat Loss Coefficient of an energetically retrofitted occupied office building
(Elsevier, 2019-03-07)
The performance gap between the design energy consumption of buildings and their real energy consumption has three main sources: the energy systems’ performance, the users’ behaviour and the buildings’ envelope performance. ...
Improvement of auxiliary BI-DRUM boiler operation by dynamic simulation
(Elsevier, 2018-02-07)
Due to Horizon 2030 objectives, industry is committed to improving traditional auxiliary bi-drum boilers performance in existing plants. In this study, a new operation methodology for auxiliary bi-drum boilers has been ...
Field assessment of thermal behaviour of social housing apartments in Bilbao, Northern Spain
(Elsevier, 2013-06-26)
A field study of 10 social housing dwellings in the north of Spain is presented in this paper. Knowing the building stock is the first step to set up priorities in a global strategy to improve the energy efficiency of the ...
Flexible dynamic model of PHEX for transient simulations in Matlab/Simulink using finite control volume method
(Elsevier, 2020-11-13)
In order to improve the energy efficiency and control of heat pump systems, it is necessary to develop dynamic models that accurately simulate their real performance. In addition, these models will help to carry out future ...
Experimental method for estimating the effect of solar radiation on the inner surface heat flux of opaque building envelope elements
(SAGE, 2024-04-10)
There still exists a considerable difference when comparing the real and the design energy consumption of buildings. The difference between the design and the real building envelope energy performance is one of its main ...
