Extreme customization for Danfoss
Background
Danfoss is a multinational corporation delivering an extensive range of products and solutions across their business segments of Power Solutions, Climate Solutions and Drives. Thanks to the sustainable and innovative technologies it develops, Danfoss has become the market leader.
Purposes
For the offices of the Kolding (Denmark) headquarters developing heat exchangers, Danfoss required a chiller capable of ensuring the highest possible efficiency. The chiller had to be equipped with Danfoss controls and the innovative Danfoss Turbocor compressors. In addition, Danfoss wanted to use the chiller as a showroom, so that visitors could see another application of Danfoss products.
Project
Together with our partner UniCool A/S we have developed a 400 kW (114 RT) air-cooled Circlemiser with oil-free centrifugal compressor and cylindrical condensers. Circlemiser is an exclusive technology that is characterized by an innovative design allowing unparalleled performance and efficiency. The chiller is designed to use HFO-1234ze, the greenest refrigerant in the world, with GWP<1 (according to a 2015 IPCC study) and classified as A2L according to ASHRAE 34. The unit ensures a high level of efficiency (EER 5.93 W/W*).
Customization
Together with Danfoss, a series of extreme customizations have been developed making this project unique:
- the unit was painted in the same color as the Danfoss brand;
- all the aesthetic details have been taken care of, such as the aluminum finish of the heat exchangers;
- the soundproofing boxes for the compressors are transparent, so that the Turbocor compressors are visible;
- the chiller was built flipped, so that the compressor compartments are facing the building and thus are visible to customers.
*Cooling kW/RT = 0.59 – Cooling EER BTU/Wh = 20.23
