摘要(Abstract):

建立了带有闪发器的空气源热泵系统的数学模型,并对其进行性能模拟分析。模拟结果表明,在低温工况运行时,带有闪发器的空气源热泵系统的制热量和COP均高于传统单级压缩系统,且其排气温度低于传统单级压缩系统约20℃。采用节流前闪蒸补气策略有利于提高空气源热泵的低温运行可靠性和制热性能。
Mathematical model of air source heat pump system with flash-tank was developed and the system performance of air source heat pump system with flash-tank was studied by analyzing the simulation results.Results showed that the heating capacity and COP of air source heat pump system with flash-tank was larger and the discharge temperature of compressor was 20℃ lower than traditional air source heat pump when the system operated in low temperature condition.Using the flash-tank as economizer was good for the improvement of the air source heat pump's reliability and coefficient of performance in cold area.
