Özet
Energy efficiency is considered an important indicator after the efficiency term is one framework of economic planning. The review results show that the gained energy is completely different in industries due to the production line, raw material, used fuel, system automation, application of thermodynamic rules, and energy recovery applications. The thermal parameters of the machining system are the main indicators to determine the system's efficiency. Dynamic behavior, effectiveness, and thermal capacity limitation are some parameters used for the optimization of machining energy efficiency. The temperature, pressure, flow rate, and other operating conditions as a function of time are the physical quantities to determine the dynamic behavior. The machining tools are intensive energy-consuming types of equipment and mostly consume electricity in manufacturing industries.The general approach for cost-effective planning is to set a complete energy-efficient system. Mass, energy, and exergy analyses are the general bases for the efficiency consideration of heat generation. But the easiest and most expeditious energy recovery is observed in effective machining like micromechanical systems and hybrid systems, up to 20% of overall losses can be recovered. If the general usage of steam to produce electricity is considered, controlling the existing configuration will improve energy efficiency by applying quantitative optimization of the electricity usage. This quantity can be increased by an extra 20%. To optimize the entire cogeneration or trigeneration machining system, a holistic approach is needed that improves the system's energy efficiency by up to 65%. The energy efficiency is increased in the range from 3 to 35% by innovative EMS. Air leaks are causing the highest energy losses in CA systems. More than 90% energy efficiency can be achieved with an appropriate CAES system mostly in isothermal and high-pressure conditions for machining purposes. Moreover, the recovered energy will mitigate GHGs. And it is strict that, any developing plan of countries which contains an energy efficiency strategy, is necessary to sustain a habitable earth.
