Unit Description
47
Zone 1 Cool, Zone 2 Heat, and Zone
3 Heat
The CIS is closed so high pressure refrigerant
vapor leaves the compressor and flows through
the DPR to the Zone 2 and Zone 3 hot gas lines
and the open HGS2 and HGS3 into the Zone 2
and Zone 3 evaporators. There, the refrigerant
heats the Zone 2 and Zone 3 evaporators and
condenses into high pressure liquid. Because
SLS2 and SLS3 are closed, the liquid refrigerant
flows through LRCV2 and LRCV3, and through
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.
