Combined cooling, heat, and power (CCHP) units can be integrated with conventional separate cooling, heat, and power production units to meet demands. The goal of this study is to develop and examine a hybrid GA-heuristic optimization algorithm for solving the unit commitment problem for integrated CCHP-thermal-heat only system with considerations for electricity boiler. When environmental emis...

The cooling efficiency of natural draft dry cooling system (NDDCS) are vulnerable to ambient winds, so the implementation of measures against the wind effects is of great importance. This work presents the combined air leading strategies to recover the flow and heat transfer performances of NDDCS. Following the energy balance among the exhaust steam, circulating water, and cooling air, numerica...

In order to cool the gas turbine vane or blade and raise operating temperature, two standard convective cooling methods are used: jet impingement film cooling. The current study uses computational analysis analyze compare effectiveness with without multi-jet on a flat plate. Ansys Fluent software is used perform results were compared experimental result using K-ω SST turbulence model validated ...

As the living standards of Chinese people have been improving, the energy demand for cooling and heating, mainly in the form of electricity, has also expanded. Since an integrated cooling, heating and power supply system (CCHP) will serve this demand better, the government is now attaching more importance to the application of CCHP energy systems. Based on the characteristics of the combined co...

Vaccine distribution to regions in Indonesia is very important and needs be considered because vaccines have different resistance temperature safety storage. spoilage can occur if it not stored under proper storage conditions. In storing vaccines, they usually use portable cooler boxes so that distributed remote areas. The latest breakthrough was made. A box using Peltier or thermoelectric elem...

Large-scale U.S. dependence on thermoelectric (steam electric) generation requiring water for cooling underscores the need to understand controls on this water use. The study objective was to quantify water consumption and withdrawal for thermoelectric generation, identifying controls, using Texas as a case study. Water consumption for thermoelectricity in Texas in 2010 totaled ∼0.43 million ac...
