Implementation of CO₂ refrigeration systems in the horenychi distribution center: future technologies available today
05.05.2026 Share
Modern distribution centers require stable cooling, precise energy control, and technologies that comply with European standards.
These principles formed the foundation for the implementation of a refrigeration system at the Horenychi distribution center (Kyiv region), where a next-generation CO₂ solution was deployed.
Next-Level Engineering Solution
The project included the development of a modern complex of low-temperature storage chambers with a total area of 5,540 m², as well as a loading/unloading zone (dock area) covering 1,520 m².
The cooling supply is provided by two independent compressor racks based on equipment from Bitzer and heat exchange equipment from Thermofin.
A key feature of this project is the use of the natural refrigerant CO₂ (R744) instead of synthetic refrigerants, which significantly improves energy efficiency.
Thanks to heat recovery from the refrigeration system:
- evaporator defrosting is performed using glycol heated by recovered heat;
- recovered heat is utilized for heating service areas and water supply;
- the system operates reliably even at ambient temperatures up to +35°C.
This approach reduces energy consumption by 10–15% compared to conventional HFC-based systems.
Why CO₂ instead of freon?
The transition to CO₂ is not just a trend, but a well-grounded engineering decision.
- Energy Efficiency
Thanks to parallel compression technology, heat recovery, and the complete elimination of electric defrosting, CO₂ systems consume significantly less electricity. - Environmental Sustainability
CO₂ has a Global Warming Potential (GWP) of 1, while conventional refrigerants can exceed 2000. This enables companies not only to comply with European environmental standards but also to demonstrate corporate social responsibility. - Heat Recovery as an Added Benefit
Excess heat from CO₂ refrigeration systems is reused for space heating and hot water supply, and fully supports the defrosting process across the entire facility—further reducing energy consumption, especially during winter.
CO₂ vs freon comparison
| Parameter | Freon System | CO₂ System |
|---|---|---|
| GWP (Environmental Impact) | 2088 (R404A) | 1 (R744) |
| Defrosting | Electric | Heat-based (heat recovery) |
Customer benefits
As a result of implementing the CO₂ solution, the Horenychi distribution center will benefit from:
- stable system operation under any ambient conditions, enabled by an adiabatic condenser;
- reduced electricity costs;
- minimal environmental impact;
- full automation via the Ralcontrol system;
- lower operational costs and fast return on investment.
CO₂ — a future-oriented technology
The experience of this project demonstrates that CO₂ refrigeration systems are the most rational choice for large distribution centers, warehouses, logistics hubs, and food industry enterprises.
