Refrigeration
Technology
At Tree, we are committed to transforming the energy efficiency of refrigeration systems, which currently account for a staggering 20% of global electricity consumption and generate more than double the CO₂ emissions of the shipping and aviation industries combined.
Our ground-breaking two-phase flow expander offers a revolutionary solution, capable of reducing electricity consumption by up to 40%, setting a new standard for energy efficiency in the refrigeration sector.
By tackling the energy-intensive demands of refrigeration, our innovative system not only helps to significantly reduce carbon emissions and combat climate change but also delivers substantial cost savings for industries reliant on refrigeration, including food processing, cold storage, and retail.
How does it work?
Our innovative two-phase turbine expander for CO₂ refrigeration systems is a cutting-edge, sustainable solution designed to enhance the performance and efficiency of CO₂ trans-critical systems. By capturing expansion energy and converting it into usable power, our turbine expander significantly reduces electricity consumption, helping to lower operational costs and minimise carbon footprints.
What sets our technology apart is its ability to be seamlessly retrofitted into existing CO₂ refrigeration systems, making it a versatile and accessible upgrade for industries seeking to adopt energy-efficient, eco-friendly refrigeration solutions.
Step 1: High-Pressure Compression in the Refrigeration Cycle
The refrigeration process begins with the compressor, where the working fluid is compressed, significantly increasing its pressure and temperature. This high-pressure gas then passes through the gas cooler, which efficiently rejects excess heat to the atmosphere, setting the stage for the next phase in the energy-efficient refrigeration cycle.
Step 2: Harnessing Energy with Our Two-Phase Flow Expander
Our revolutionary two-phase flow expander transforms the traditional expansion process by replacing the standard expansion device with a high-performance system that captures expansion energy. This captured energy is efficiently converted into electrical power, while simultaneously delivering a low-pressure liquid optimised for the evaporator. By integrating this innovative technology, we enhance the overall energy efficiency and sustainability of CO₂ refrigeration systems.
Step 3: Efficient Heat Absorption in the Evaporator
The refrigeration cycle concludes as the liquid refrigerant enters the evaporator, where it efficiently absorbs heat from the cooled space. This critical process ensures optimal cooling performance while maintaining energy efficiency, making it a key component in advanced CO₂ refrigeration systems.
