Fig: Coal boilers
Fig: Ambient air type condensers using massive water
Extremely inefficient coal boilers are usedUse of ambient air type condensers (massive quantity of water is discharged)No waste water treatment is implemented (diluted by massive quantity of water)No measurement of the utility consumptionImprovement of refrigeration system is desired due to high electricity tariffNo concerns for fuel energy saving because of cheap coal prices

High Efficient Refrigeration System
High Efficient Refrigeration System
Cascade cooling system Multi-stage cooling consumes less energy than single stage
cooling for a large temperature differential
Dynamic ice system It stores ice during the off-peak period and shuts off
refrigeration machines during the peak period. It reduces the electric power for pumps and the investment
cost due to the high transportable heat density together with ice
Heat recovery system Hot water is produced from high temp. NH3 discharged gas in
the refrigeration system and used in brewery instead of steam.

Process control and operation are fully automated in breweries in Japan.
However, employees are more involved in the manual operation of the process rather than fully automated operation in Vietnam.
Involvement of operator in the manual operation must be considered in designing the operation and control system and through training.
