POM DESCRIPTION
When maximum bleed air heating or cooling is required in the cabin or
cockpit, the TMV either bypasses all bleed air flow from the HX or
directs all bleed air flow through the HX. The bleed air exiting the TMV
is ducted into the aircraft pressure vessel through check valves mounted
on the AFT Pressure Bulkhead (APB).
Air Conditioning
Air conditioning (cooling) of the conditioned air is performed using a
Vapor Cycle System (VCS).
