Exergy

According to first law of thermodynamics energy is neither be created nor be destroyed.In the other words it neither appears nor disappears then how can one produce, Save, Conserve the energy. It is clear, but we have to conserve some thing what is it. There comes the term EXERGY.

We have to conserve Exergy but not Energy.

The exergy of a system is the maximum possible work during a process that brings the system into equilibrium. The term Exergy comes into the picture only when there is a potential difference existence between the system and surroundings, but where as energy always exists in the system.

Energy of a system is always constant but where as Exergy always decreases when the system is tending towards the equilibrium.

Energy never talks about the thermal friction but exergy always quantifies the thermal friction and gives a path to the energy engineers to decrease the thermal friction so that the Efficency of the system can be improved.


“The Exergy century has begun. Fight against the thermal friction.”
