Abandu Jackson

exergy charging efficiency is greater than energy charging efficiency because it uses the principle of energy conservation.

Hitesh Bindra

Exergy charging efficiency is always smaller than energy charging for a practical sensible heat TES system as there is always additional entropy generation in the charging process.

Bambang Sudarmanta

In fact, thermodynamic processes always produce entropy, because in this thermodynamic process, there is occur friction and heat transfer into the atmosphere. During this process there is also a loss of energy so the process is called an irreversible process.
