Question

Difference between reversed carnot cycle and bell coleman cycle

Answer 1

For Joule’s Cycle:

1 is compression of fuel in engine

2 is combustion of fuel in engine

3 is expansion of burnt fuel in gas form

4 is exhaust is sent out

And For Bell Coleman Cycle:

1 is compression of refrigerant in compressor

2 is conversion of liquid form of refrigerant in gaseous form

3 is expansion of refrigerant to create pressure drop viz ultimately to drop temperature

4 is to take Heat from surrounding

That is how they are differ even though they look same as because of constant pressure lines.
