Jamaica's climate and geography place specific demands on ventilation system design. The following are suitable scenarios and recommendations for ERV (Energy Recovery Ventilation) applications:

1. Tourist Resorts (such as Montego Bay and Negril)

Climate: Tropical maritime climate with an average annual temperature of 27°C, high humidity (70%-90%), and distinct dry seasons (December-March) and rainy seasons (May-June, September-November).

Applicability: ERV systems balance indoor and outdoor temperature and humidity, reducing air conditioning loads. They are particularly suitable for enclosed spaces such as hotels and beachfront villas, 

recovering exhaust energy through heat exchange and reducing energy consumption.

Recommendation: Incorporate moisture-proof design to prevent equipment corrosion caused by high humidity.

2. Blue Mountain Coffee Growing Area

Geographical Environment: Above 2,000 meters above sea level, with relatively low temperatures (average annual temperature of 20°C), large diurnal temperature swings, and frequent fog and rain. Applicability: 

ERV systems regulate ventilation in plantations or processing plants, maintaining fresh air while reducing heat loss. They are suitable for coffee bean storage environments that are sensitive to temperature 

and humidity.

3. Urban Buildings (e.g., Kingston)

Demand Background: Jamaican urban buildings mostly rely on natural ventilation, but high-rise or enclosed buildings require mechanical ventilation.

Applicability: ERV systems resolve the conflict between ventilation and energy conservation, and are particularly suitable for locations requiring continuous air exchange, such as office buildings and hospitals. 

They comply with the local "Technical Requirements for Cleaning and Disinfection of Ventilation and Air-Conditioning Systems" (JG/T 400-2025).

4. Precautions

Hurricane Protection: June to November is hurricane season, so ensure that the ventilation system is windproof.

Maintenance Requirements: Clean filters regularly to prevent tropical dust from clogging air ducts.

For a specific design plan, it is recommended to optimize it based on local climate data (e.g., annual precipitation in the Blue Mountains exceeds 3,000 mm) and building codes (e.g., GB50365-2019).
