摘　　要：文章建立了带闪发器前节流的涡旋压缩机热泵系统的数学模型,以哈尔滨的气象参数为例,利用迭代算法,对带闪发器的热泵系统进行了模拟仿真计算,比较了补气系统和单级压缩系统的性能,得出闪发器系统模式和普通单级压缩系统模式的最佳切换区域。The mathematical model of front-restrictor heat pump system with flash-tank in scroll compressor is built. Taking the meteorological parameters of Harbin for an example, and using the iteration algorithm, the performance of heat pump system with flash-tank is simulated and calculated. Comparing the performance of reinforcing gas system with that of single-stage compression system, the best transition regions of flash-tank system mode and ordinary single-stage compression system mode are obtained.
