Zone 1 Cool and Zone 2 Heat
The CIS is closed so high pressure refrigerant
vapor leaves the compressor and flows through
the DPR to the Zone 2 hot gas line and the open
HGS2 into the Zone 2 evaporator. There, the
refrigerant heats the Zone 2 evaporator and
condenses into high pressure liquid. Because the
SLS2 is closed, the liquid refrigerant flows
through the LRCV2 and the liquid line to the
LLS1.
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.
In the condensing unit, the CIS valve closes and
opens to regulate head pressure. The purge valve
is opened continuously during heat to drain the
condenser coil.
