On aircraft with an ACM air conditioning, where does the final cooling take place? Is it in the ACM expansion turbine or in the ACM compressor?
Where does the final cooling take place in the air cycle machine of the air conditioning system?
$\begingroup$ Specifically, please elaborate on what kind of air conditioning system you're referring to. Are we talking about airliners here? Single-engine pistons? $\endgroup$– reirabMay 2, 2017 at 16:05
$\begingroup$ Yes,it is about jet engine a/c $\endgroup$– KM320May 2, 2017 at 16:13
3$\begingroup$ Related, the different temperatures in the a/c system. The last cooling occurs at the turbine stage. From this answer. $\endgroup$– minsMay 2, 2017 at 18:11

The final cooling will be at the turbine of the ACM.
Air passes through two heat exchangers, before finally passing through the turbine of the ACM.
