Entropy

This paper first introduces the concept of “exergy”, which quantifies what is consumed by any working systems from man-made systems such as heat engines to biological systems including human body. “Exergy” balance equation for a system can be derived by c

This paper outlines the applicability of the “exergy” concept to describe the built environment for a better futuristic view of heating and cooling systems to be developed. We briefly review the fundamental laws of thermodynamics aiming at the derivation
