The HXP is comprised of three Heat Exchangers (HX). Ambient
(cooling) air entering the HX Pack first passes through a VCS condenser.
The condenser exhaust air then passes through the LH and RH HX which
are in parallel. There are two sources for ambient (cooling) air; the
Ground Cooling Fan (GCF) on the ground and two ram air inlets located
at the base of the vertical stabilizer in flight. The GCF draws air in close
proximity to the inlet grille. The ambient air is exhausted overboard on
the RH side of the AFT baggage compartment. Operation of the GCF is
automatic based on the demand for air conditioning in the cabin, or bleed
air cooling.
