According to search results, Nicaragua's natural landscape and climate are suitable for the application of ERV (Energy Recovery Ventilation) systems, particularly in the following areas:

1. Lake Managua Area

The region has a hot and humid climate (average annual temperature 24-27°C). The lake's elevation is 39 meters above sea level, resulting in high humidity. This makes ERV systems suitable 

for regulating indoor and outdoor air exchange while also recovering energy to reduce air conditioning loads.

2. Western Lowlands (such as León and Granada)

The western region has a tropical savanna climate, with a dry and hot dry season (November-May) and concentrated rainfall during the rainy season (May-November). ERV systems can balance 

ventilation needs between the dry and wet seasons, reducing energy waste.

3. Eastern Coastal Plains

With year-round high temperatures and high rainfall (tropical rainforest climate), ERV systems can effectively control indoor humidity, prevent mold growth, and improve energy efficiency through heat exchange.

4. Volcanic Highlands (such as Ometepe Volcano)

The region experiences large temperature swings between day and night. ERV systems can stabilize indoor temperatures and reduce heating/cooling energy consumption.

Note:

Local voltage is 110V, so please confirm device compatibility.

During the rainy season, increased moisture protection is required to prevent condensation on the system.
