The search for new and improvement of existing technical design energy converter systems specific consumers requires a reasonable choice the most rational these objects. Thermotransformers that operate on reverse mixed thermodynamic cycles, in combination with power plants utilizing renewable non-traditional primary (fuel), are considered to be interest small-scale generation (trigeneration sys...

Rising awareness for the environment as well concerns over sustainability of fossil fuels has encouraged developed and developing countries to find alternative ways enhance thermal efficiency current power systems. The plants can be increased from 30 – 40 % up 80 90 through implementation a trigeneration system by recovering dissipated waste heat other purposes. defined technology that produce ...

This paper firstly studies the influence of variations in fuel tariffs and GHG emissions grid electricity on financial environmental metrics, demonstrating divergences when considered alone. Secondly, a combined economic objective function is proposed, yielding good compromise between both concerns. Real data are available from Brazilian Northeast building where electricity, heat (hot water), c...

A solar trigeneration system for off-grid households, based on photovoltaic-thermal (PV/T) collectors, photovoltaic (PV) modules and a heat pump (HP), whose aim is to provide enough electricity, domestic hot water (DHW), heating and cooling power to meet the typical demand of an offgrid single family dwelling, is modeled to predict its performance, enable system sizing and evaluate the impact o...

Energy storage makes energy continuously available, programmable, and at power levels different from the original intensity. This study investigates feasibility of compressed-air (CAES) systems on a small scale. In addition to CAES systems, there are two TES (thermal storage) for recovery calories frigories. The micro-CAES + system is designed single-family residential building equipped with ph...
