Energy-saving solutions in refrigerated containers
Refrigerated containers are an indispensable element of logistics, allowing the transport of perishable goods such as food, medicine and flowers. However, their operation involves high energy consumption, which increases costs for businesses and increases their carbon footprint. Modern energy-saving technologies offer effective solutions to reduce these costs while maintaining optimal cargo conditions.
The main reasons for energy consumption of refrigerated containers
Refrigerated containers use energy to maintain a set temperature, ventilate, and control humidity within the container. The main factors influencing the level of energy consumption:
- The quality of the container's thermal insulation.
- Temperature differences between the external environment and the internal space.
- Refrigeration capacity and efficiency.
- Duration of transportation and frequency of door openings.
These factors stimulate the development of technologies aimed at reducing energy costs.
Energy saving technologies
Improved thermal insulation materials
Modern refrigerated containers are equipped with highly effective insulation made of polyurethane foam or airgel, which can significantly reduce heat loss. These materials not only maintain optimal temperature conditions, but also reduce energy consumption by refrigeration units.
Inverter compressors
Inverter technology allows refrigeration compressors to adjust power based on current conditions. This is especially important when transporting in conditions with variable temperatures. Instead of operating at maximum power, the compressor adapts to actual needs, saving up to 30% of energy.
Heat recovery systems
Some modern refrigerated containers are equipped with recovery systems that use the heat generated during cooling to heat other parts of the system. This reduces overall energy consumption.
Intelligent control systems (IoT)
With the help of sensors and Internet of Things technologies, refrigerated containers can independently control the temperature, humidity and operating mode of the refrigeration unit. Such systems optimize energy consumption by adapting to external conditions and cargo characteristics.
Solar panels
The most environmentally friendly solution is to install solar panels on the roof of the container. This technology makes it possible to compensate part of the energy consumed from renewable sources. It is especially effective for transport in sunny regions.
Energy efficient fans
Modern, low-energy fans circulate air inside the container. They help maintain an even temperature distribution with minimal energy consumption.
Practical examples of implementing energy-saving solutions
Maersk company has introduced Star Cool refrigeration systems, which save up to 50% energy compared to traditional installations.
Lloyd's table is testing containers with solar panels that provide additional power to control IoT systems.
CMA CGM has developed a line of refrigerated containers with innovative thermal insulation materials and inverter compressors, which reduces their carbon footprint.
