Traditional HVAC systems often prioritize temperature and airflow, but not humidity. HVAC equipment that offers humidity control typically does so at a high energy cost. At AirGreen, our proprietary dehumidification technology provides a viable alternative for indoor humidity control without the high energy usage associated with traditional air conditioning (HVAC) systems. Our solutions remove moisture directly from the air and also scrub pathogens such as bacteria, mold, and viruses—including COVID-19—to improve safety and indoor air quality.

The AG2200 is our original unit. It moves up to 2,000 cubic feet of air every minute and can operate at a significantly lower sensible heat ratio (SHR) than standard commercial equipment. The AG2200 runs on heated and cooled water for its regeneration and cooling loads. The system uses a closed-loop desiccant system to remove moisture and cool the air, with two separate units to handle air conditioning and regeneration.

AG2200 Air Conditioning Unit

The AG2200 Air Conditioning unit uses four absorbing stages to remove moisture from inbound air. Air gets cooled as comes directly into contact with concentrated liquid desiccant present on our proprietary wetted media. This direct contact encourages heat and mass transfer while avoiding atomization.  The liquid desiccant circulates through a series of plate heat exchangers fed by a cooling fluid—usually water or a water/glycol mix—which provides cooling in each stage to keep the working fluid cool.

The conditioned air emerges from the unit both drier and cooler, as low as 55°F and 40-50% relative humidity, creating an environment of superior comfort. The diluted desiccant is then pumped into the AG2200 Regenerator to be re-concentrated for reuse in the air conditioning unit.

AG2200 Regenerator Unit

Once the desiccant has been diluted by absorbing ambient moisture from the air, it moves into the AG2200 Regenerator unit. In a reverse approach to the AG2200 Air Conditioning unit, the moisture that has been absorbed by the desiccant is released to the exhaust air stream through direct contact with a heated liquid desiccant on wetted media. This heated liquid desiccant warms using a relatively low-temperature hot water source, which can come from heat pumps, solar hot water, cogeneration (CHP), or other renewable resources.

Sizing Considerations

We manufacture our innovative solutions in numerous sizes to suit a variety of application needs. Some common applications include:

  • Indoor Agriculture
  • Grocery Stores
  • Schools
  • Indoor Pools and Recreation Centers
  • Data centers
  • Biopharma Production Facilities

The experts at AirGreen can help you determine the appropriate solution for your facility. If your system has considerable sensible load sources, such as light heat, windows, electronics or other sources, it is often advisable and attractive to split the solution between standard cooling equipment for the sensible load and an AirGreen unit for the latent or humidity load. This allows you to balance your capital costs and required airflow while achieving your desired humidity control at significant cost savings.

Benefits of Working with AirGreen

The unique design of the AirGreen AG2200 unit provides you with an alternative to high-energy traditional mechanical cooling systems. Our reliable, precise, economical temperature and humidity control systems can save up to 60% on energy costs compared with traditional HVAC systems that cool air down to the dew point and then re-heat. We provide similar savings compared to dry desiccant wheel equipment.

AirGreen’s proprietary technology quickly surpasses traditional air conditioning and dehumidification equipment in situations where humidity control is important, such as grocery stores, agricultural facilities, biopharmaceutical production facilities, schools, and more.
