Abstract: A refrigeration system including a flooded evaporator. The flooded evaporator additionally includes a liquid evaporator refrigerant composition and a vapor evaporator refrigerant composition. The liquid refrigerant composition includes difluoromethane (HFC-32), and 2,3,3,3-tetrafluoropropene (R-1234yf) and the vapor refrigerant composition includes difluoromethane (HFC-32), and 2,3,3,3-tetrafluoropropene (R-1234yf). The mass fraction of difluoromethane in the liquid evaporator refrigerant composition is lower than the mass fraction of difluoromethane in the vapor evaporator refrigerant composition and the mass fraction of 2,3,3,3-tetrafluoropropene in the liquid evaporator refrigerant composition is greater than the mass fraction of 2,3,3,3-tetrafluoropropene in the vapor evaporator refrigerant composition.

Abstract: A process of thermal fluid reclamation includes combining at least two recovered thermal fluids including at least two refrigerant compounds to form a consolidated thermal fluid. The consolidated thermal fluid is a blend of the at least two refrigerant compounds having a consolidated composition different from a recovered composition of at least one of the least two recovered thermal fluids. The process also includes testing the consolidated thermal fluid and validating that the consolidated thermal fluid has greater than 95 wt % organic purity. The process further includes adding at least one virgin thermal fluid or used thermal fluid to the consolidated thermal fluid to form a reconstituted thermal fluid. The process yet further includes analyzing and purifying the reconstituted thermal fluid to form a reclaimed thermal fluid. The reclaimed thermal fluid has a predetermined reclaimed thermal fluid composition different from a consolidated thermal fluid composition of the consolidated thermal fluid.

Abstract: Example embodiments disclose a method of managing refrigerant reclamation including returning used refrigerant to a facility for reclamation, analyzing, via an analyzer unit, composition of the used refrigerant, determining, via the analyzer unit, purity of the used refrigerant, generating an analysis report based on the composition of the used refrigerant, determining weight of the used refrigerant based on the purity of used refrigerant, and generating a deposit credit to be used on-site or remotely.
