Thermodynamic Principles for Large Commerical Aircraft

 

 

Explain the laws of thermodynamics with regards to the air-conditioning system used in large wide-body commercial aircraft e.g. 747-400.
Illustrate how the cold air travels with an aircraft compartment.
Describe how the conditioned air gets replaced by continuous circulation and ejection of stale air through skin valves, e.g. outflow valve.
