DAC has successfully completed BRIdgeAlfa program

Time to say goodbye…


DAC has successfully completed BRIdgeAlfa program by Narodowe Centrum Badań i Rozwoju.


Starting from 8/2020 DAC team conducted R&D works financed by NCBR BRIdge Alfa program (Poland) and Shape VC. The goal of the program was to create a TRL6 prototype suitable for refrigeration and application as a central air-conditioning unit. Results were confirmed by client trials verifying key parameters of the technology.


Prototype construction works were fully completed in December 2021. DAC team built an 18kW device (TRL6), capable of achieving a stable temperature delta of -80°C, operating with COP 1,2 at temperatures below -20°C.

Trials were conducted in February 2022 using various combinations of equipment available at selected partner locations.

All conducted trials confirmed the high effectiveness of DAC technology for both air-conditioning and refrigeration purposes. In particular, the successful application of the 18 kW DAC unit in the oversized cooling chamber of 1100m3 (currently cooled by 80kW vapor-compression installation) showed the great potential and effectiveness of DAC technology.


DAC together with our partners will continue cooperation on implementation of DAC technology for storage of agricultural products, blast-freezing line for the production of frozen vegetables and fruits as well as testing DAC prototype AC installation for large commercial/office spaces. These works are co-financed by the EU through the European Innovation Council and SMEs Executive Agency (EISMEA) EIC Accelerator program and are planned to start in May 2022.
