Dedicated Outside Air Rooftop Solution
A Dedicated Outdoor Air System (DOAS) is a specialized HVAC solution designed to efficiently condition 100% fresh outdoor air before it enters a building. By independently controlling humidity and temperature, often with integrated energy recovery technology, DOAS units significantly improve indoor air quality by diluting pollutants and optimizing energy efficiency. Their flexible design allows for seamless integration into both new and existing HVAC systems, making them a smart choice for enhanced comfort and healthier indoor environments.
Description
A Dedicated Outdoor Air System (DOAS) is a specialized HVAC system designed to handle the conditioning of 100% fresh outdoor air before it’s introduced into a building’s indoor spaces.
Dedicated Fresh Air Supply: Unlike traditional HVAC systems where outdoor air is often mixed with return air and then conditioned, a DOAS unit specifically focuses on treating only the incoming outside air.
Independent Humidity and Temperature Control: A DOAS unit is highly effective at managing both the latent load (humidity) and a portion of the sensible load (temperature) of the outdoor air.
Energy Efficiency: Many DOAS units incorporate energy recovery technologies, such as heat exchangers or energy recovery wheels. These components capture energy (heat or coolness) from the exhaust air and transfer it to the incoming fresh air.
Improved Indoor Air Quality (IAQ): By bringing in and conditioning 100% outdoor air, DOAS units help dilute indoor pollutants and provide cleaner, fresher air to occupants.
Flexibility in Design: DOAS can be implemented in various configurations, either as an addition to an existing HVAC system or as an integral part of a new building’s design.
