| Summary: | HP-1 is an eco-friendly HFOs refrigerant known for its favorable thermodynamic properties and environmental attributes. Its critical parameters and saturated vapor pressure are close to those of R245fa. It has the potential to replace R245fa, which has a high global warming potential (GWP), in high-temperature heat pumps. The the flammability, solubility, and material compatibility of HP-1 were mainly developed by expriment. The results indicated that HP-1 had a flammability range of 9.75% to 16.1%, exhibited excellent solubility with MK220 lubricating oil at elevated temperatures, and good compatibility with materials used in high-temperature heat pump systems. When HP-1 is applied to high-temperature heat pump units, the condensing temperature of the unit can reach up to 125°C when the evaporating temperature is between 50-70°C, with a heating capacity of 99.27kW to 153.14kW, and a coefficient of performance (COP) of 2.25 to 4.85. |
