A novel method to measure the energy efficiency and performance of an auto-cascade refrigeration cycle
Elsevier (2023-10)Auto-cascade refrigeration systems are the most used cycles to maintain spaces at ultra-low temperature conditions (-80 to −60 °C). The interest in these systems has risen due to the need to maintain and distribute COVID-19 ... -
Development of a low-medium temperature T-history setup for the thermal storage characterization of non-homogeneous mixtures containing PCMs
Elsevier (2023-12-25)More attention has been paid to thermal energy storage in recent years for its advantages in heating and cooling applications to foster the use of renewable energies. As part of the design of new thermal energy storage ... -
Energy influence of the internal heat exchangers placement in a cascade refrigeration plant. A theoretical and experimental analysis
Elsevier (2024-05-01)This paper deals with the analysis of the internal heat exchanger (IHX) impact on the energy performance of a cascade refrigeration plant (CRS) made up of two vapor compression cycles. Three IHX locations have been considered, ... -
Influence of subcooling in R-449A supermarket refrigeration system and screening of refrigerant mixtures for its energetic and environmental improvement
Elsevier (2024-01-10)Current demands of the cooling sector are focused on using refrigerants with a low Global Warming Potential (GWP) and increasing energy efficiency in vapour compression installations. The main objectives of this paperwork ... -
Performance evaluation of modified compound organic Rankine-vapour compression cycle with two cooling levels, heating, and power generation
Elsevier (2023)This work analyses a novel combined organic Rankine-compound ejector vapour compression cycle for power, cooling and heating production using a low-grade ground heat source as the primary heat source. Ultra-low global ... -
Renewable and waste heat applications for heating, cooling, and power generation based on advanced configurations
Elsevier (2023)Using renewable heat energy sources, recovering the waste heat, and enhancing the processes and energy efficiency can reduce the electricity dependency of several industrial applications. Renewable and waste heat have ... -
Towards sustainable process heating at 250 °C: Modeling and optimization of an R1336mzz(Z) transcritical High-Temperature heat pump
Elsevier (2024-04-01)Fossil fuel boilers typically produce high-temperature process heating due to the impossibility of current renewable technologies. Vapour compression heat pump systems have been proposed up to 200 °C with subcritical cycles. ...
