Panama has a tropical maritime climate with year-round high temperatures and humidity. The installation of an ERV (Energy Recovery Ventilation) system requires careful 

consideration of both the climate and the building structure. The following are suitable installation locations and technical requirements:

I. Unit Installation Location

Rooftop Platform

Applicable to single-family homes or low-rise commercial buildings. Requires:

Rain and sun protection (IP54 rating)

Maintain a distance of 3 meters or more from the cooling tower (to prevent hot air recirculation)

Equipment Room/Technical Mezzanine

High-rise buildings are preferred and require:

Mechanical exhaust system (air changes ≥ 6 times/hour)

Shock-absorbing foundation (rubber isolation pads with a natural frequency ≤ 5Hz)

II. Airflow Design

Air Inlet

Located on the upwind side of the building and lower than the exhaust outlet (bottom ≥ 2 meters above the ground).

Avoid pollution sources such as restaurant exhaust vents and cooling towers.

Exhaust Ventilation

Horizontally 1.5 meters and vertically 3 meters from the air inlet. Preferentially located near pollution sources such as kitchens and bathrooms. Centralized Areas

III. Special Area Adaptation

Residential Areas

Use ceiling-mounted ERVs (ceiling height ≥ 2.8m)

Locate air inlets on balconies or exterior walls (avoid conflict with air conditioner outdoor units)

Commercial and Dining Areas

Independent exhaust system (air volume ≥ 2000m³/h)

Physically isolate exhaust ducts from the ERV system

IV. Climate Adaptability Measures

Moisture-Proofing Treatment

Condensate Pipe Slope ≥ 0.5% (enhanced drainage required during tropical rainy season)

Use B1-grade rubber-plastic insulation (thickness ≥ 25mm)

Intelligent Control

Automatically adjust fresh air volume based on indoor and outdoor humidity (target humidity 60% ± 5%)

Can switch to 100% fresh air mode during transitional seasons

Note: During Panama's dry season (December-April), ERV operation frequency can be reduced appropriately; dehumidification should be enhanced during the rainy season.
