Refrigeration systems are among the pieces equipment in a food plant that use more electricity for their operations, as lowering the temperature of products in the chilling cycle and freezing products requires a lot of energy. Better maintenance and proper usage increases the efficiency of refrigeration systems, making them last longer and use less energy. A good refrigeration system contributes towards saving money and using better systems improves a plant's energy performance. Tips for energy saving are: 1. Reduce heat load and temperature lift. 2. Use better insulating materials. 3. Minimize head pressure. 4. Avoid additional heating sources. 5. Maintain pumps and fans. 6. Avoid overloading. Energy reduction starts with a smart design which does not take cheap energy for granted. Existing systems can have an energy audit to determine how they can become much more efficient.
