Sudan (including South Sudan) has a tropical desert climate, characterized by extreme high temperatures (reaching over 40°C during the day) and significant dust and sandstorms. 

The following is an analysis of applicable scenarios for ERV (Energy Recovery Ventilation):

I. Key Application Areas

Khartoum, the capital, and its economic centers

Commercial Buildings: Efficient ventilation is required in enclosed spaces such as shopping malls and hotels. ERV can reduce air conditioning energy consumption by 30%-50%.

High-end Residential Buildings: A constant oxygen environment can be achieved by integrating intelligent control systems (such as CO₂ sensor linkage).

Industrial Facilities

Power Plant Equipment Rooms: Power facilities such as the Geely Power Plant require stable ventilation. ERV can filter dust and recover exhaust heat.

Chemical Fiber/Chemical Industry Workshops: Industrial environments requiring temperature and humidity control and corrosion resistance.

II. Technical Adaptation Recommendations

Dust-Proof Design: A three-stage filtration system (primary, medium, and high efficiency) is required. Reference is made to the SVG room dust control solution.

High-Temperature Adaptability: Select high-temperature-resistant materials (such as aluminum alloy heat exchangers) to ensure continuous operation at 50°C.

III. Restricted Areas

Northern Desert Regions: Extreme sandstorms are frequent, requiring additional sealing, which may increase maintenance costs.

Simplified Buildings: For economically efficient locations, a combination of natural ventilation and localized mechanical ventilation is recommended.

Note: South Sudan's hot and humid climate makes HRV (sensible heat recovery) systems more suitable, so consider your selection accordingly.
