BASIC REFRIGERATION CYCLE
Beginning with the Parallel Compre s s o r s ,
vapor refrigerant is compressed into the
Discharge Manifold and flows to the Tu r b a -
shed. The Turba-shed separates the vapor
refrigerant from liquid oil by centrifugal force
and screen baffles. The oil is stored in the
bottom of the Turba-shed and returned to the
compressors.
A 3-Wa y Heat Reclaim Va l v e ( H S )
directs the refrigerant to either the
condenser or a Heat Reclaim Coil.
When the HS solenoid is de-energized
the valve directs the refrigerant to the
condenser.
The Condenser d i s c h a r ges the
unwanted heat from the system.
The Flooding Valve maintains head pressure in
low ambient conditions by reducing the
available condensing area. Restricting liquid
refrigerant flow from the Condenser, the
Flooding Valve prevents the liquid refrigerant
from leaving the Condenser as fast as it is
forming, so the Condenser floods with its own
condensate.
