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