BEgreen™ Chill utilizes a patent pending absorption refrigeration process enhanced by liquid-jet gas compressors. The rotating equipment used for the motive liquid is a centrifugal pump. Refrigerant is propane (R290) or similar.
With a global warming potential (GWP) of 3 and an ozone depletion potential (ODP) of 0, R-290 is of very little threat to the environment. Refrigerant temperatures below -40 °F can be achieved.
Application of the design can be part of CO2 sequestration, oilfield natural gas liquid (NGL) recovery from produced natural gas, industrial refrigeration, and commercial HVAC.
