The primary resource for industrial refrigeration systems is electrical energy, used to power compressors and other types of motors that make up the entire system. Therefore, at Inditer, we believe that energy efficiency in industrial refrigeration is of utmost importance for achieving optimal service with the lowest possible costs.
Refrigeration is fundamental in various industrial processes and has become an indispensable pillar for numerous types of machinery. Food production and preservation require systems that keep them fresh for longer, extending their commercial life.
Its correct use will determine the energy efficiency of industrial refrigeration, both in terms of environmental conservation and the operating costs involved.
It is worth noting that the characteristics of the facilities will be crucial for the performance of a refrigeration system. Operations must adapt to the nature of the product and the required thermal levels.
For high-level heat, the temperature should be around 60°C (dry). For low-level heat, it should be maintained between 10°C and 25°C (humid), thereby reducing environmental impact and energy consumption.
How to Optimize Industrial Refrigeration Systems
To have an efficient industrial refrigeration system, it is essential to consider the following aspects:
1. Installations
It is essential to know the dimensions and characteristics of the space where the system will be installed to correctly determine the number of compressors, condensers, evaporators, and expansion systems needed.
2. Verification of Equipment Operation
Each system component plays a key role. Inefficient operation leads to unnecessary increases in electricity consumption and energy billing.
The following elements should be periodically checked:
- Compressors: must operate at adequate power without losses due to poor condensation or excessive temperature rise.
- Condenser: must ensure thermal dissipation without overworking the compressor.
- Defrost processes: must be regulated by intelligent systems that prevent unnecessary cycles.
- Pipe insulation: reduces thermal leaks and improves energy savings.
3. Energy Balance
A correct energy balance allows for adjusting consumption and optimizing the refrigeration system’s performance.
4. Operating Parameters
Continuous monitoring of performance—daily, monthly, or annually—allows for early detection of deviations and failures.
It is advisable to establish indicators such as kWh/ton to monitor electricity consumption.
5. Facility Maintenance
Continuous maintenance prevents breakdowns, reduces unnecessary consumption, and extends the equipment’s lifespan.
Supervision through remote management systems allows for controlling pressures, detecting failures, and implementing continuous improvement programs.
Evaporator Operation
To achieve high efficiency in industrial refrigeration, correct evaporator operation is essential. The higher the evaporation temperature, the lower the energy consumption.
An increase of just 1°C can result in energy savings of between 1% and 4%.
- Avoid ice accumulation.
- Ensure proper air circulation.
- Keep heat exchangers clean.
- Properly size suction lines.
- Replace filters regularly.
- Adjust the evaporation temperature to the maximum allowed.
Tips for Achieving Energy Efficiency in Food Refrigeration Systems
In food refrigeration, energy efficiency is key to ensuring proper food preservation.
- Avoid frequent door openings.
- Do not open opposing doors simultaneously.
- Unload directly from refrigerated trucks.
- Do not block air returns.
- Avoid introducing hot products.
- Adjust to the minimum necessary temperature.
- Synchronize production and demand.
- Cover food when advisable.
