Three large compressors have been installed behind a glass wall in the meeting center at Danfoss headquarters in Denmark so customers and guests can see the product in operation. The Turbocor units provide cooling for the ventilation system and other cooling systems in the main office building.
The compressors replace an old ammonia-based refrigeration plant and have three times higher efficiency, saving the company 165,000 kWh annually on electricity and almost 40 metric tons of CO2. The smallest chiller delivers 250 kW cooling, and the largest delivers 466 kW. They use the environmentally friendly refrigerant R-1234ze with a global warming potential (GWP) number of 7.
