    Short Interview Question Answer on Necessity of Aircraft Cooling  Why Is The Necessity of Aircraft cooling? In an aircraft, cooling systems are required to keep the cabin temperatures at a comfortable level. Even though the outside temperatures are very low at high altitudes, still cooling of cabin is required due to: (i)  Large internal heat […]

    * Open and Closed Air Refrigeration Cycles

    Open and Closed Air Refrigeration Cycles  TWO WAYS OF OPERATING OF BELL COLEMAN CYCLE (i) Open air refrigeration cycle: When cooled air from the turbine enters the cabin and comes in physical contact with the occupants. It is not much in use because of moisture added to air in the cabin. (ii) Closed air refrigeration cycle OR dense […]
