Remote Harvest Cycle (Models J450/J600/J800/J1000)
Harvest Cycle Refrigeration Sequence
Hot gas flows through the energized hot gas valve,
heating the evaporator. The hot gas valve is sized to
allow the proper amount of hot gas into the
evaporator. This specific hot gas valve sizing, along
with the harvest pressure regulating (H.P.R.) system,
assures proper heat transfer, without the hot gas
condensing to liquid and slugging the compressor.
The harvest pressure regulating (H.P.R.) valve helps
maintain the suction pressure during the harvest
cycle. (See “H.P.R. System” on page 7-26.)
