WebA Brayton cycle that is driven in the reverse direction is known as the reverse Brayton cycle. Its purpose is to move heat from the colder to the hotter body rather than produce work. This cycle is also known as the gas refrigeration cycle or the Bell Coleman cycle. This type of cycle is widely used in jet aircraft for air conditioning systems ... http://www.mhtlab.uwaterloo.ca/courses/me354/lectures/pdffiles/web7.pdf
The efficiency of the ideal Brayton cycle is = = () /, where is the heat capacity ratio. Figure 1 indicates how the cycle efficiency changes with an increase in pressure ratio. Figure 2 indicates how the specific power output changes with an increase in the gas turbine inlet temperature for two different pressure ratio values.
