What is a dedicated outdoor air system?

New standards for energy efficiency for commercial heating in addition to cooling systems are driving innovation in the HVAC industry.

As a result, new HVAC systems help suppliers better maintain indoor temperature levels in addition to improve air quality while lowering their carbon footprint.

In a push for better energy efficiency, manufacturers supply commercial proprietors with configured rooftop units known as dedicated outdoor air systems (DOAS). A dedicated outdoor air system is an HVAC component installed outdoors in addition to is constantly used in conjunction with other HVAC equipment! Dedicated outdoor air systems bring fresh outdoor air into your indoor space independently from cooling or heating efforts. Addressing air conditioning in addition to ventilation separately can save HVAC fan energy while enhancing indoor air quality. The type of appliances used with a dedicated outdoor air system can vary depending on building type in addition to brand name. In some instances, a chilled water system is applied to supply your DOAS cooling with chilly water, then other dedicated outdoor air system models may use digital scroll compressors, an electric expansion valve, in addition to a microchannel condenser coil to cool, heat, in addition to dehumidify your indoor air. While dedicated outdoor air systems may help suppliers to comply with the new commercial HVAC energy efficiency standards, several other benefits come with the system. They improve indoor air quality by eliminating contaminants from the outside air before delivering it into your indoor space. The systems are effective dehumidifiers, in addition to they help prevent problems related to moisture, such as sick building syndrome. Decoupling ventilation from air cooling in addition to heating also results in energy savings.
