Future-proof refrigeration technology for the air conditioning of office buildings
Two QUANTUM Air chillers installed above the rooftops of Hamburg provide perfect air conditioning for an office building in the Hanseatic city.
-
The two air-cooled QUANTUM A0680 chillers have a total cooling capacity of around 1.2 megawatts.
-
With the refrigeration technology for air conditioning the office building, the customer saves around 100 tons of CO2 per year.
Outstanding quality, sustainability and future-proofing - our customer, an operator of a large office building in Hamburg, attached particular importance to these. Our team of experts met these requirements in full by using tailor-made refrigeration technology to air-condition the office building. Two QUANTUM Air chillers with a total cooling capacity of 1.2 megawatts above the rooftops of the Hanseatic city reliably supply the office space with cooling. They replace five previous machines, some of which were no longer functional and therefore had immense operating costs.
Efficient refrigeration technology? Ideal climate!
Thanks to the integration of free cooling in one of the two chillers, the high operating costs for air conditioning the office building are history. This is because the free cooling system kicks in as soon as the ambient temperature is below the chilled water temperature. As a result, the compressors of the chillers pause during this time, significantly reducing electricity consumption and thus lowering the system's energy-related CO₂ emissions. In addition, both air-cooled QUANTUM chillers run with the future-proof refrigerant R-1234ze. The refrigeration technology for air conditioning the office building is also adapted to the environmental factors of the Hanseatic City of Hamburg: Protective grilles prevent seagulls or other birds from interfering with system operation. In addition, the condensers are corrosion-resistant - important in view of Hamburg's harbor air. Ultimately, our customer benefits in every respect from the modern refrigeration technology for air conditioning his office building. The highlight: Overall, the refrigeration technology from ENGIE Refrigeration reduces CO₂ emissions by approximately 100 tonnes per year compared to the replaced systems – a measurable contribution to reducing this building's carbon footprint.
