  • DROP-IN RECYCLED REFRIGERANT COMPOSITIONS HAVING NO NET GWP BEING A DROP-IN REPLACEMENT FOR R-32 AND R-454B
    Publication number: 20240117232
    Abstract: A refrigerant composition includes about 90-92 wt % difluoromethane and about 8-10 wt % pentafluoroethane. The refrigerant composition is formed from all recycled materials, and the refrigerant composition is a zeotrope. A method of preparing the refrigerant composition includes injecting a mixture of recovered refrigerants into the center of a distillation column, the mixture of injected refrigerants being difluoromethane, pentafluoroethane and chlorodifluoromethane, removing from the top of the distillation column a refrigerant composition of about 90-92 wt % difluoromethane and about 8-10 wt % pentafluoroethane, and removing chlorodifluoromethane from a bottom of the distillation column.
    Type: Application

  • Drop-in recycled refrigerant compositions having no net GWP
    Patent number: 11746271
    Abstract: A refrigerant composition includes about 90-92 wt % difluoromethane and about 8-10 wt % pentafluoroethane. The refrigerant composition is formed from all recycled materials, and the refrigerant composition has a net global warming potential of about 0. A method of preparing the refrigerant composition includes injecting a mixture of recovered refrigerants into the center of a distillation column, the mixture of injected refrigerants being difluoromethane, pentafluoroethane and chlorodifluoromethane, removing from the top of the distillation column a refrigerant composition of about 90-92 wt % difluoromethane and about 8-10 wt % pentafluoroethane, and removing chlorodifluoromethane from a bottom of the distillation column.
    Type: Grant

  • Drop-in recycled refrigerant compositions having no net GWP replacing R-410A
    Patent number: 11655407
    Abstract: A refrigerant composition includes about 63-66 wt % difluoromethane and about 33-36 wt % pentafluoroethane. The refrigerant composition is formed from all recycled materials, and the refrigerant composition has a net global warming potential of about 0. A method of preparing the refrigerant composition includes injecting a mixture of recovered refrigerants into the center of a distillation column, the mixture of injected refrigerants being difluoromethane, pentafluoroethane and chlorodifluoromethane, removing from the top of the distillation column a refrigerant composition of about 63-66 wt % difluoromethane and about 33-36 wt % pentafluoroethane, and removing chlorodifluoromethane from the bottom of the distillation column.
