Suggested Media Piping
for Gravity Refrigeration
Liquid refrigerant from the receiver is stored in a surge drum
located above the Votator II. The level in the surge drum is
automatically controlled by the level system provided with the
equipment. Gravity forces the refrigerant into the cooling jacket
where it comes into contact with the heat transfer tube. The warm
product causes a portion of the liquid refrigerant to change
phase, causing the heat transfer tube and the product to be
cooled. The cooling rate is controlled by the refrigerant back
pressure, and hot gas can be used to push the liquid refrigerant
from the Votator cylinder and rapidly warm the system.
NOTE:
Set high pressure regulating valve 5 to 10 psi higher than
outlet pressure of hot gas pressure reducing valve and lower than
the relief setting.
