Figure 7-2. Self-Contained Harvest Cycle
Harvest Cycle Refrigeration Sequence
Hot gas flows through the energized harvest valve,
heating the evaporator. The harvest valve is sized to
allow the proper amount of refrigerant into the
evaporator. This specific sizing (along with the proper
system refrigerant charge) assures proper heat transfer,
without the refrigerant condensing and slugging the
compressor.
