DOAS / 100% Outdoor Air and Exhaust Air Energy Recovery Systems for IAQ

Indoor Air Quality - Schools, Office Buildings, Extended Care Facilities, Libraries, etc...

• Outdoor Air / IAQ Requirements and System Design - Introducing outdoor air to facilities to meet code has an impact on the design of required HVAC equipment.
  
  • To meet stringent IAQ requirements, facilities must often significantly increase supply of outdoor ventilation air, which in many cases introduces excess moisture.
  • Conventional temperature controlled air handlers are unable to control the much larger moisture loads that result.
  • Using a dedicated outside air system (DOAS) helps overcome the moisture load problems associated with introducing 100% outdoor air to a facility.

• ASHRAE Standards 62 and 90.1 - Desert Aire's DOAS equipment is designed to meet ASHRAE standards 62 and 90.1.
  
  • When preconditioning outdoor air before feeding it to a traditional air handler, the dehumidifier reduces moisture content and air temperature to meet typical return air requirements.
  • When directly feeding the space, our patented “free” reheat system controls leaving air temperature to an exact and controllable level.

• Enthalpy Wheels and Q-Pump - Proven IAQ designs that incorporate features such as our enthalpy wheel and patented Q-Pump (our 100% outdoor air, non-reversing, water-source heat pump) offer energy efficient options while providing exceptional temperature control with lower energy consumption.
