Question

Jet aircrafts fly at altitudes above 30, 000 ft where the air is very cold at – 400C and the pressure is 0.28 atm. The cabin is maintained at 1 atm pressure by means of a compressor which exchanges air from outside adiabatically. In order to have a comfortable cabin temperature of 250C, we will require in addition

Choices

Choice (4) Response

a.

A heater to warm the air injected into the cabin

b.

An air-conditioner to cool the air injected into the cabin

c.

Neither a heater nor an air-conditioner; the compressor is sufficient

d.

Alternatively heating and cooling in the two halves of the compressor cycle
