Optimizing Refrigeration Systems: Savings Within Reach

Refrigeration is an essential component in many places, especially in locations like supermarkets, arenas, cold storage warehouses, or food processing plants. These systems often account for more than 50% of the energy bill in the buildings where they are located. However, despite their importance, they are often managed without considering their environmental impact.

The most common method for resolving a failure in a refrigeration system is to lower the suction pressure. However, this approach has a direct effect on energy consumption, often much more than one might think. But this is not the only factor that influences the energy efficiency of refrigeration systems. Join us as we explore the issues that can hinder these systems and the optimization strategies to improve their efficiency.

Common Malfunctions

Some frequent problems affect the efficiency of refrigeration systems. Here are a few:

• Compressors and condenser fans starting and stopping improperly
• Fouling of condenser and evaporator fins
• Excessive discharge pressures from compressors
• Inappropriate defrost cycles
• Poorly adjusted refrigerant temperature at evaporator outlets
• Inefficient or non-existent compressor heat recovery

These malfunctions not only increase energy consumption but also shorten the lifespan of system components. Fortunately, several simple and inexpensive interventions can correct these issues.

How to Optimize Refrigeration Systems?

Here are some actions to take to improve the performance of these systems:

• Follow a strict preventive maintenance schedule to prevent equipment fouling
• Adjust control settings so each component operates at optimal efficiency
• Implement control sequences that allow real-time adjustments to setpoints based on needs

These interventions not only save energy but also extend equipment lifespan and reduce power demand.

Better management of refrigeration systems can generate substantial energy savings while reducing the environmental impact of your facilities. With simple and inexpensive adjustments, it’s possible to extend the lifespan of your equipment, reduce your energy bills, and lower your ecological footprint. In short, a win-win situation for everyone, and for the planet!
