Mauritania's extreme climate and geographical environment place special demands on ventilation equipment, particularly regarding the suitability ofenergy recovery ventilators (ERVs). 

Based on the country's specific circumstances, the following areas and scenarios may be particularly suitable for deploying such equipment:

Nouakchott, the capital, and its surrounding areas

As a political and economic center, this region is home to government agencies, commercial facilities, and residential areas. Chinese-aided water treatment projects have significantly improved infrastructure. 

ERV systems can be used in new public buildings or renovations to address summer heat and dust.

Nouadhibou Special Economic Zone

As Mauritania's "economic capital," this city boasts a fishing port, mining facilities, and a free trade zone, brimming with industrial activity. 

ERV systems are suitable for locations requiring temperature and humidity control, such as factory workshops and cold chain warehouses, while also reducing energy consumption.

Animal Husbandry Technology Demonstration Center

The China-aided Idini Village Demonstration Center has achieved localized environmental improvements through alfalfa cultivation and dairy farming techniques. 

Installing ERVs in livestock sheds can optimize air quality and reduce the impact of heat stress on animals.

China-Africa Green Technology Park

The Gobi Oasis Park, located east of Nouakchott, showcases China's technological achievements in desertification control. 

Such ecological building projects typically require efficient ventilation systems, and ERVs can balance energy consumption with indoor and outdoor air exchange.

Coastal Cities and Fisheries Facilities

The West African Coastal Management Program (WAKA) is promoting coastal ecological protection. Processing plants in fishing ports like Nouadhibou can use ERV systems to 

treat high-humidity air while also recovering energy.

Technical Adaptation Recommendations:

Select ERV equipment made of corrosion-resistant materials (such as galvanized steel) to cope with high-salinity coastal environments.

Prioritize low-noise models to avoid disturbing residential areas or animal habitats.

Integrate with solar power systems to compensate for unstable power grids in some areas.
