DESIGNING DEDICATED OUTDOOR AIR SYSTEMS WITH VALENT
Introducing, and managing, increased levels of fresh air has become even more important in the face of unprecedented demand to create safe and healthy indoor environments. Whether it is reducing viral transmission, eliminating unseemly odors, or simply creating a fresh space to learn or work, mechanical equipment can no longer just heat and cool the building – it must be capable of bringing in high levels of outside air.
THE DOAS CHALLENGE
The very nature of bringing in high levels of outdoor air means that equipment must be designed to handle wide variations of outdoor air temperature and humidity while keeping indoor conditions consistent and comfortable. Oh, and it would ideally happen at low operating costs. What’s the right combination of features to meet this challenge? That’s where Valent comes in.
WHY CHOOSE VALENT?
Valent’s highly configurable, dedicated outdoor air rooftop units are designed to handle up to 100% outdoor air and operate in the most efficient manner possible. Choose Valent for affordable quality and optimized building performance by including key design features.
KEY FEATURES FOR DOAS UNITS
Robust Cabinets – To handle widely varying outdoor air conditions
2”, double wall, foam-injected cabinet construction keeps the treated air in and the hot/cold/humid air out. Valent’s cabinets are designed to
last for decades.
Quiet Components – To minimize un-wanted noise
A noisy rooftop can create a distraction for both occupants and neighbors. Valent units have ultra-quiet condenser fans with serrated blades that are up to 12 dB quieted than
standard fans. Inverter scroll compressors provide an average 20% IEER improvement over standard compressors. The compressor sits on an insulated shelf off the floor to keep compressor noise contained.
Energy Recovery – To reduce operating costs
When bringing in high levels of outdoor air, all possible efforts should be made to reduce the amount of energy needed to heat, cool, or dehumidify that air. Whether it’s
a highly efficient energy recovery wheel or a low cross-contamination plate, Valent offers a wide variety of energy recovery options.
Easy & Efficient Controls – To create operational excellence
When handling large amounts of outside air, control sequences must be flexible and fluid while adjusting to a variety of operating modes. Valent’s factory-mounted
controllers, with site-specific control sequences, allow for a smooth start-up and efficient daily operation.
