A dry cooling coil placed in the supply duct gently lowers the temperature of incoming fresh air.
What a ventilation cooling coil does
In a balanced ventilation system, fresh outdoor air is filtered and passed through an energy recovery core. A dry cooling coil placed in the supply duct then gently lowers the temperature of that incoming fresh air, so the air delivered to the room is comfortable rather than warm and humid.
Why it is not air conditioning
A split air conditioner recirculates the same indoor air. A ventilation cooling coil only treats incoming fresh air as it enters the building. It works with the ventilation system to deliver fresh, filtered, and tempered air — it does not replace ventilation, and ventilation does not replace it.
The result in a tropical climate
The combination means a building receives a steady supply of fresh, filtered air at a comfortable temperature — ideal for Thailand’s hot and humid conditions where simply opening a window is not an option.
