Abstract:
Refrigeration systems are majorly used in food industry especially in manufacturing
of dairy products. “GEA Grasso Ice-water system” is one of these refrigeration
systems being used at Engro foods. With every running plant there is always an area
for improvement to make it more energy and cost efficient. With our solutions to
enhance the COP of the current ammonia refrigeration system, we have managed to
make it cost effective. It includes using R32 as a potential refrigerant and VFDs
(Variable Frequency Drives) on both the condenser and compressor fans. Design
considerations for both the Evaporator and Condenser are also discussed
