Hybrid AHU

At the heart of HMX Indirect Evaporative Cooling is DAMA, a cross-flow plate type heat exchanger that separates the air into which moisture has been added to create cooling from the air that is supplied to the conditioned space. The end result is supply air that has had no contact with water and is cooled almost to the ambient wet bulb temperature.

There is no increase in absolute moisture in the cooled air coming out of DAMA.

Conventional Air Handling Units (AHUs) are generally designed to handle about 10% outdoor air. At times they may operate with an even lower outdoor air ratio in case the occupancy level of the conditioned space is higher than the assumed design level. Increasing the quantity of outdoor air is recommended for health reasons, but increases energy consumption significantly. HMX-Hybrid AHU (Air Handling Unit) combines the benefits of high proportion of fresh air – as high as 35% (pre-cooled by Indirect Evaporative Cooling) – but without an increase in energy consumption and without any compromise in the cooling provided.

• Maintains a healthier indoor air quality.
• Improves people productivity — no sick building syndrome.
• Saves energy during heating periods.
• Helps drive out harmful contaminants from the conditioned space.
• Eliminates the use of complex technologies like recovery wheels.
• Helps reduce carbon emissions.

HMX-Hybrid AHU is ideally suited for centrally air-conditioned applications for industrial and commercial spaces. This solution can be incorporated in both new building designs and existing buildings. The design air flows can be customised to suit pressurisation and other requirements while maintaining similar levels of performance of the heat exchanger.
