Khartoum moves solar air conditioning

Does Khartoum have a cooling system?

As noted before, Khartoum’s climate is characterized as having low relative humidity; consequently, this cooling strategy can provide thermal comfort for building users. In order for this cooling strategy to function best, 100% external air movement should be guaranteed.

How to cool buildings in Khartoum?

Several suitable passive and active cooling strategies can be applied to buildings in Khartoum. Based on Climate Consultant 6.0 analysis, two-stage evaporative cooling seems the most suitable cooling strategy for Khartoum in both dry and wet seasons of the year.

How does evaporative cooling work in Khartoum?

According to Sharag-Eldin (1988), during the hot season of the year in Khartoum, two-stage evaporative cooling can reduce dry bulb temperature to 29 °C and increase relative humidity to 60% provided outside air blends with inside air upon entry.

Why is two-stage evaporative cooling important in Khartoum?

This shift means two- stage evaporative cooling should be adapted to reduce any discomfort that may occur and to reduce active cooling load. The combined use of both active cooling and two-stage evaporative cooling is valuable in Khartoum because together they can improve thermal comfort up to 59.5%.

Can wind towers be enhanced for future buildings of Khartoum?

Furthermore, wind towers could be enhanced for future buildings of Khartoum by adding evaporative cooling effect and using filters to control sand-dust storm, this way a reduction in cooling load could be achieved.

Are future design strategies for Khartoum sustainable and climate responsive?

With the climate data projections for 2070, future design strategies for Khartoum can be proposed to achieve sustainable and climate responsive building designs. The design strategies adapted in this research work for both the contemporary and future climate of Khartoum.
