摘要

HP-1是新一代环保HFOs制冷剂

由于其具有良好的热力学性能、环保性能及其临界参数和饱和蒸气压均与R245fa接近的性质

具有替代高GWP的R245fa用于高温热泵等领域的潜力。本文主要通过理论与实验的手段

对HP-1的可燃性、溶油性和材料相容性等关键物性展开研究。研究结果表明：HP-1可燃极限为9.75%-16.1%

与MK220润滑油高温下互溶性良好

与高温热泵系统材料相容性良好。HP-1应用高温热泵机组

在蒸发温度50-70℃时

机组冷凝温度均可达125℃

制热量为99.27kW-153.14kW

COP为2.25-4.85。

Abstract

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.
