The Role of DOAS in Modern HVAC: Fresh Air Meets Energy Efficiency
-
In the world of HVAC, one system plays a critical role in maintaining indoor air quality (IAQ) without sacrificing energy efficiency: the Dedicated Outdoor Air System, or DOAS. While traditional HVAC systems typically focus on controlling temperature and humidity within a building, DOAS is specifically designed to manage the flow of fresh outdoor air into indoor spaces. This article will look into how a DOAS unit works, its core benefits, and why LG's DOAS units stand out in the market.

01 What is a DOAS (Dedicated Outdoor Air System) Unit?
A Dedicated Outdoor Air System (DOAS) is an HVAC solution that provides 100% outdoor air* and manages humidity independently. Unlike traditional systems, DOAS preconditions outdoor air, improving indoor air quality by diluting pollutants and controlling humidity.
*This applies when installed in the outside air intake mode.
-
02 How Does a DOAS Unit Work?
DOAS units use a heat exchanger to recover energy from exhaust air, which is then used to precondition incoming air. This reduces overall energy consumption and enhances comfort by balancing temperature and humidity levels independently of the main HVAC system.
The unit's advanced filtration further removes pollutants from outdoor air, improving indoor air quality and helping to meet strict ventilation standards.

04 Key Features and Advantages of DOAS
DOAS units provide a comfortable indoor environment by maintaining stable temperature and air quality, while achieving significant energy savings through advanced heat recovery technology. With outstanding dehumidification performance, they ensure optimal humidity levels for added comfort and air quality. Additionally, their user-friendly design simplifies operation, making DOAS an efficient and convenient solution for maintaining a healthy indoor climate.
-
Unlike regular indoor units, LG DOAS offers precise control over supply air temperature and allows partial load operation during localized cooling and heating. This reduces energy waste by preventing overcooling, resulting in a more efficient and targeted approach to maintaining indoor comfort.
