REFPROP uses the most advanced methods for estimating property data. REFPROP also provides high accuracy data for mixtures such as ammonia-water and most organic refrigeration mixtures. Included in the database are the "natural" refrigerants, carbon dioxide, ammonia, propane, isobutane and other hydrocarbons. The National Institute of Standards and Technology (NIST) has developed REFPROP (also called NIST Standard Reference Database 23), which provides high accuracy property data for pure refrigerants and refrigerant mixtures.
