Abstract
This invention relates to hydrofluorocarbons useful in refrigeration and heat pump applications. The invention provides hydrofluorocarbons selected from the group of 1,1,2,3,3-pentafluoropropane, 1,1,1,3,3-pentafluoropropane, 1,1,1,2,3-pentafluoropropane, and mixtures thereof that are environmentally suitable replacements for chlorofluorocarbons in refrigeration applications such as multi-stage centrifugal chillers.
