EPR Inlet Pressure Upstream
Regulator
Limits the minimum
refrigerant pressure in the
hopper (currently set to 60
psig).
Limiting the minimum
refrigerant pressure in the
hopper prevents freezing of
product mix on the hopper
wall.
Filter/Dryer This keeps moisture, dirt,
metal, and chips from
entering the refrigerant
flow control valves.
Heat
Exchanger
(sub cooler)
This allows the liquid
refrigerant to be cooled
before it reaches the AXV
and TXV.
When the liquid is
subcooled before it
reaches the refrigerant
control, the refrigeration
effect per unit mass of
refrigerant is increased.
AXV Automatic expansion
valve of the freezing
cylinder circuit.
Controls the refrigerant
flow during the cooling of
the freezing cylinder.
