A paradigm shift is happening in the way the HVAC systems of the building have been designed for ages. RH Control is also being looked at critically even in commercial buildings and the air conditioning design is also being modified to address this. Divide and Conquer concept is becoming more and more popular and handling the building's internal moisture load using Ventilation Air is gaining popularity.
DRI Dedicated Outdoor Air Systems (DOAS) are the first choice of designers today for handling the moisture load using Ventilation Air. After having studied almost 20 configurations DRI have the following standard DOAS configurations in their product Range:
Hexair - R series
Incorporating the highest recovery Enthalpy Wheels, EcoFresh, the HEXAIR - R Series has a refrigeration system on board.
Some of the key features are:
Integrated with cooling units helps free up space, simplify installation, reduce operating cost, and minimize capital cost.
Gives designer the ability to deliver cool and dehumidified air after energy recovery cooled using an onboard condensing unit independent of any chiller/chilled water supply or external condensing unit/VRF unit.
Delivered fresh air is closer to the Room Temperature Neutral condition
Benefits
Delivering room neutral fresh air at no additional load on room cooling units.
Ideal for retrofit cases.
Product is ideal in cases where the building is not having a chiller.
Gives you the ability to supply fresh air directly to space.
Special mixing boxes can be avoided.
Hexair - MR series
DRI Hexair - MR DOAS uses a combination of Enthalpy and Desiccant wheels. The unit has a refrigeration unit built onboard. Some of the key features are:
HEAXIR - MR integrates desiccant dehumidification, cooling unit, and energy recovery to maintain RH in conditioned spaces.
The system also utilizes waste heat to regenerate specially customized desiccant wheel series thereby increasing the moisture removal capacity.
The unit provides space neutral leaving temperature and low dew point to take care of room latent internal loads.
Dehumidification is at no extra energy cost, as it uses the waste heat of the condensing coil to regenerate the desiccant wheel.
The system is the most energy-efficient as it eliminates the need for energy-guzzling over cooling and reheats. It can be 100% outdoor air or can work on partial outdoor and re-circulation air.
Common for DOAS
These units are ideal for Hospitals, Hotels, Offices, Airports, Educational Institutes, and all the air-conditioned areas where RH management is required.
The units are manufactured in ISO Certified state of Artfully vertically integrated facility with world-class machinery, units have a unique design to incorporate enthalpy wheels to maximize energy recovery efficiency and minimize cross-contamination.
