In comparative purchases, scant regard is paid to the qL=h1-h4 or the Carnot cycle
in the process of purchasing a fridge .
This important and dynamic field studies fuel cells that can achieve higher efficiencies for energy conversion than conventional systems based on the Carnot cycle
The Carnot cycle
is often used to derive a mathematical expression for the 2nd law of thermodynamics.
He drones: "An air-conditioning unit is just the physical manifestation of the Carnot Cycle
- which is talking about the exchange between two closed systems.
Any energy-conversion limitations imposed by the Carnot cycle
apply equally to hydrogen and gasoline.
