Recommended areas in Costa Rica suitable for ERV ventilation system

ERV (Energy Recovery Ventilation System) is particularly suitable for environments with high humidity and large temperature fluctuations. It can effectively recover energy and 

regulate indoor air quality. Costa Rica's climate is characterized by rainy wet season (winter) and dry dry season. Some areas have high humidity or significant temperature 

differences all year round, and the demand for ERV is high. Considering the climate and geographical conditions, the following areas are most suitable for installing ERV systems:

Caribbean coastal areas (such as Puntarenas Province and Limon Province)

This area has high temperature and high humidity all year round (average night temperature 21°C, average daytime temperature 30°C), frequent rainfall, especially in the wet season

 (May-November) humidity can reach more than 80%. For example, in Puerto Viejo and Gandoca-Manzanillo Wildlife Refuge, ERV systems can effectively fight mildew caused by humid air, 

balance the temperature difference between indoor and outdoor, and improve living comfort.

Cloud forest areas (such as Monteverde) ‌

Monteverde is located in the Cordillera Mountains and is surrounded by clouds and fog all year round. The relative humidity exceeds 90%, and the vegetation is covered with dense moss, 

resulting in extremely high air humidity. ERV systems can recover moisture from the fog and reduce ventilation heat loss, which is suitable for eco-hotels and residences in this area. ‌

Tropical rainforest reserves (such as Talamanca Yangzhi-La Amistad) ‌

The reserve straddles the border between Costa Rica and Panama, with dense rainforests and abundant rainfall in the wet season. In high humidity environments, ERVs can work 

with air conditioning systems to reduce energy consumption and maintain indoor air circulation, especially for resorts or research facilities around rainforests. ‌

Central Valley cities (such as San José, Alajuela) ‌

The average annual temperature in the capital San José is 15°C–26°C, and the daytime temperature in Alajuela in July reaches 31°C and the night temperature reaches 24°C‌. Humidity rises sharply 

during the wet season (June-October). The ERV system can meet the ventilation needs of densely built urban areas, reduce moisture and mold problems, and achieve significant energy-saving effects.

Selection Recommendations

Prioritize coastal and rainforest areas: The high humidity environment of the Caribbean coast and cloud forests is the core application scenario of ERV, and the central valley cities also benefit in the wet season.

System advantages: ERV can recover up to 60% of humidity in Costa Rica's wet season, reducing the dependence on dehumidification equipment; in the dry season, heat exchange is used to maintain ventilation 

efficiency.

Installation considerations: It is recommended to combine local architectural characteristics (such as tree house hotels) and choose a corrosion-resistant material system to adapt to the tropical climate.
