Finalists: Carrier, i-Vu Express Connected Building Automation Appliance (Booth S7510); Copeland, Copeland CC200 Case Controller (Booth S7110)

Cooling

Winner: DanfossInnovation: DSG CompressorAHR Booth: N2510

The DSG has been specifically designed for low-pressure, low-GWP refrigerants such as R1234ze. Applications include chiller systems, with a wide range of compressor capacities available to support unit design requirements. These refrigerants would usually require a much larger compressor size to have the same capacity as high-pressure refrigerants. As chiller manufacturers will need to transition to lower-GWP refrigerants, they will need to move to medium and low-density refrigerants. The DSG will enable a smooth transition without a significant increase in physical compressor size. It is qualified for R1234ze, a replacement for the market that has been dominated by R134a for many years, but will be phased down due to its impact on the environment.

The DSG can also be used with other refrigerants with similar properties, so it offers a great deal of flexibility for manufacturers to choose without requiring a new compressor design. This will also support future refrigerant changes and regulations without requiring significant modifications.

Refrigeration

Winner: AirGreenInnovation: AirGreen-BMIL Brine-Based DX Cold Room Heat PumpAHR 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 55°F with a 40-45°F dewpoint, and to lower the dry bulb temperature to as low as 33°F 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 down time related to multiple defrost cycles, or worse, down time for cleaning if condensation forms.

Further, the AirGreen product only needs low regeneration temperatures (about 110°F), compared to solid desiccants requiring 180°F or more. This low-temperature hybrid brine system is uniquely suited for cold storage applications and addresses a $5.1 billion market.

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