Final Report - DEW-COOL (Investigation of a Novel Dew Point Cooling Heat and Mass Exchanger for Air Conditioning of Buildings in Europe)

Project ID: 220079
Funded under: FP7-PEOPLE


The conventional air conditioning systems are neither sustainable nor environment-friendly. Evaporative cooling utilises an ambient energy (latent heat of water evaporation) to perform air conditioning of buildings, and is therefore a potential replacement of existing systems. However, evaporative cooling has several technical difficulties that impede its wide application. Direct evaporative cooling adds moisture to room air which causes unpleasant thermal comfort. Indirect evaporative cooling limits supply air temperature to some degrees above the wet bulb of the outdoor air, which is too high to perform air conditioning of buildings.

The research aimed to optimise the design of the exchanger in terms of its material, structure and geometric sizes, and to develop a new polygonal-sheets-stacked exchanger. The new exchanger will be 15 to 35 % higher in cooling effectiveness that allows the dew point cooling become a widely applicable system for building air conditioning in most regions of Europe. The report includes a table of the project.
