-
Provides 100% dehumidified outside air for code required ventilation needs
-
Delivers verifiable outside air for occupants
-
Rooftop or indoor mounting
-
Shown with hot water or chilled water
-
Packaged DX and gas heat suitable
-
Geothermal suitable
-
Typically energy recovery based
-
Desiccant devices suitable
-
Isolates rooms so no room-to-room airside cross contamination occurs
-
Provides chilled water for QLCI and possibly DOAS chilled water coi
-
Air-cooled or water-cooled suitable
-
If DOAS unit is packaged DX, dedicated elevated chilled water to QLCI offers high efficiency operation
-
Alternatives
-
No Chiller Design Option (only HW available) Packaged DX DOAS applied and designed to deliver cool, dehumidified primary air for recognized sensible cooling in space
-
Geothermal water applied – Electrification
-
Heat recovery chiller – Electrification
-
Provides hot water for QLCI zone heating and possibly DOAS hot water coil
-
Often high efficiency condensing style boilers applied
-
Gas fired or electric boiler suitable
-
Alternatives
-
If existing steam source available, apply a steam-to-hot water conversion
-
Some climate designs may not require hot water in the zone
-
Geothermal water applied – Electrification
-
Heat recovery chiller – Electrification
-
Receives 100% outside air from DOAS unit to drive room air induction process across integral coil
-
Chilled water and hot water flow modulated to control sensible space loads
-
Supply air delivered near floor in displacement mode for
-
Effective removal of airborne contaminants for better IAQ
-
Low velocity, temperate air for enhanced thermal comfort
-
No moving parts to maintain, produce noise, or consume electricity
-
Provides industry leading system efficiency due to displacement ventilation and fluid-based heat transfer
-
Utilizes same 100% OA from DOAS unit for ventilation air to spaces
-
Utilizes same chilled water and hot water to control sensible space loads
-
Keeps the HVAC mechanical system congruent versus applying another technology
-
Applied in smaller, less occupied spaces for improved thermal comfort and acoustics
-
No moving parts to maintain, just like QLCI in classrooms
Comparative Analysis – System Technologies
The heart of Carson Solutions’ displacement induction ventilation and chilled beams operation is the Dedicated Outside Air System or DOAS (100% OA) unit.
In order to understand the different system approaches, we have put together a comparative analysis between a DOAS-DIV (chilled beam) system and other typical HVAC approach such as AHU-VAV, DOAS-FCU, DOAS-VRF, and stand-alone Unit Vents.
See for yourself the system, operational, and beneficial characteristics of the DOAS-DIV system delivers compared to other systems!
