Combining DOAS and VRF, Part 1 of 2

Pairing a dedicated outdoor-air system (DOAS) with a variable-refrigerant-flow (VRF) system can provide: • Simplified system design. • Increased efficiencies.

Variable-air-volume (VAV) systems with air terminal units have been used extensively in commercial and institutional buildings in the United States for decades. Unfortunately, optimized design of a VAV system with terminal heat is difficult at best because of limitations inherent in VAV and complications posed by design standards and regulations. One new approach involves the pairing of a dedicated outdoor-air system (DOAS) with a variable-refrigerant-flow (VRF) system. By separating th
