Zone 1 Cool and Zone 2 Null
High pressure refrigerant vapor leaves the
compressor and flows through the open CIS to the
condenser, where refrigerant condenses into high
pressure liquid. The liquid refrigerant flows
through the receiver tank into the Zone 1 liquid
line.
The LLS1 is open so the refrigerant flows through
the Zone 1 expansion valve into the Zone 1
evaporator. There, the liquid refrigerant cools the
Zone 1 evaporator as it evaporates into low
pressure vapor. The refrigerant returns to the
compressor through the SLS1, suction line,
SLCV1 and the accumulator.
The LLS2 is closed, which prevents refrigerant
from reaching the Zone 2 evaporator.
