AirGreen-BMIL Brine-based DX Cold Room Heat Pump

Booth #S9377

The innovative AirGreen-BMIL brine-based DX refrigerant system essentially creates a low dewpoint “heat pump” for cold room applications – providing <26F dewpoint supply air in a single process step. Because of its simplicity and efficiency, this packaged unit design provides up to 50% energy savings while also significantly reducing capital costs. Solid desiccant products can only achieve supply air at 55F with a 40-45F dew point, and to lower the dry bulb temperature to as low as 33F it requires three or more pieces of equipment at considerable capital and energy penalty. The unique low temperature brine solution achieves this performance because it simultaneously cools and dehumidifies. For customers, it also eliminates the downtime related to multiple defrost cycles, or worse, downtime for cleaning if condensation forms. Further, the AirGreen product only needs low regeneration temperatures (~110F), compared to solid desiccants requiring 180F or more. This low temperature hybrid brine system is uniquely suited for cold storage applications and addresses a $5.1B market. 

Customers will benefit both from precise supply air temperatures and the demonstrated energy savings of this design approach.
