Development of Dessicant Dew point Cooler (DDC 1) - Phase 1
The project co-finances a PhD study that focuses on modeling of dehumidifier wheel and Dewpoint Cooler to be included as components in a newly developed ventilation system Dessicant Dewpoint Cooling (DDC). DDC is a heat-driven ventilation system that can replace electricity with heat from district heating, waste heat, solar or biomass.

DDC is a heat-driven ventilation system that can replace electricity with heat from district heating, waste heat, solar or biomass. Ph.D. study builds on results from a thesis, which has achieved good results from an air conditioning system that utilizes waste heat from a transcritical CO2-refrigeration system. The project plans to coordinate this research part of the overall technology development with a development, which subsequently applied for by ELFORSK, to quickly exploit the huge market potential of this energy-efficient system will have, both in Denmark, but especially in southern Europe, America and Southeast Asia.
The work in the project is primarily carried out in the PhD project Analysis of a solid desiccant cooling system with indirect evaporative cooling.
The project has focused on a refrigeration system that uses indirect evaporative cooling. The aim has been to quantify the performance of the system for varying dimensions and operating conditions as well as to identify possible areas of application with the results.
Finally, the purpose has been to in-vestigate energy-efficiency of the system. The work has been based on numerical modeling of the components of the system. In the system, the components are combined to increase the cooling capacity and efficiency of the system. The use of the exhaust air from the conditioned room for the indirect evaporative cooling showed the most promising results with a thermal COP above 1 and an electrical COP above 20.
Finally, a new technical solution is introduced that aims to make desiccant refrigeration systems independent of external water sources
