Dedicated Outdoor Air System Doas

A Dedicated Outdoor Air System (DOAS) is a specialized type of HVAC system that is specifically designed to deliver temperate outdoor air directly into a building or space. Unlike traditional HVAC systems, DOAS are designed to provide only outdoor air, rather than trying to heat or cool it. This makes them highly efficient and cost effective as they do not require the expenditure of energy to heat or cool air. Additionally, by supplying only fresh outdoor air, DOAS can reduce the risk of indoor air pollution, helping to improve air quality and reduce health risks for occupants.
