Electricity consumption is rising due to population growth, climate change, urbanization, and the increasing use of electronic devices. The trend Internet Things has contributed creation devices that promote thrift efficient electrical energy. Currently, most projects relating this issue focus solely on monitoring energy without providing relevant parameters or switching on/off Therefore, paper presents in detail design, construction, validation a smart meter with load control aimed at being...

<h2>Abstract</h2> This study conducts a numerical comparison of the thermal performance three distinct working fluids (pure water, TiO₂, and SiO₂ water-based nanofluids) within an evacuated tube solar collector using Computational Fluid Dynamics. The evaluates thermohydraulic alongside global local entropy generation rates, while considering variations in radiation values inlet mass flow rates. Results indicate that nanofluids demonstrate superior under low radiation,...

The heat transfer in double pipe exchangers is very poor. This complicates its application absorption cooling systems, however, the implementation of simple passive techniques should help to increase and mass mainly absorber. paper carried out a simulation experimental comparison NH3-H2O bubble process using tube exchanger with helical screw static mixer both central annular sides. results showed that load per area 31.61% higher than smooth tube. theoretical difference values were 28.0 21.9%...

The energy consumption for space cooling is growing faster than any other end-use in buildings, more tripling between 1990 and 2016. Energy efficiency an important topic the drive to reduce of electricity, particularly air conditioning. This paper presents a simulation absorption system with parabolic trough collector under dynamic conditions using TRaNsient SYstem Simulation (TRNSYS) software. thermal analysis seeks evaluate storage tank at three different configurations: (1) sensible heat,...
