The report gives results of an experimental investigation to develop an acceptable flow model for short tube orifice expansion devices used in heat pumps. The refrigerants investigated were two hydrofluorocarbon (HFC) mixtures considered hydrochlorofluorocarbon (HCFC)-22 replacements: HFC-32/HFC-125/HFC-134a (23/25/52% on a mass percentage basis) and HFC-32/HFC-125 (50/50%).
