摘　　要：建立了气液双热源耦合换热器的耦合换热模型,并对其在耦合热源热泵空调中应用时的制热工况进行了性能模拟研究。模拟结果显示,使用该气液双热源耦合式换热器的耦合热源热泵空调系统,气液双热源模式与单空气热源模式相比,制热量和COP均有明显提高,低温时性能提高更为显著。当室外温度为-15℃时,双热源热泵的制热量较单一空气源热泵提高比例进一步增大,制热量提高近40%,COP提高近30%。In this paper,the mathematical model of air-liquid dual heat source coupled heat exchanger was established,and the compound heat exchange performance and heating performance of coupled heat pump with the coupled heat exchanger was simulated.The simulation results proved that based on comparison of the single air source mode with air-liquid mode of the coupled heat pump with the compound heat exchanger,the heating capacity and COP of the gas-liquid mode are all raised evidently,especially in low air temperature.When the outdoor temperature is-15℃,the dual-source heat pump＇s heating capacity rises by nearly 40%,COP increases nearly 30%.
