Energy recycling and sustainable development problem is imminent and condensing heat recovery technology in air source heat pump has received considerable development and application in recent years. In this article the experimental method is used to mainly explore the performance of four kinds of condensing heat recovery system (e.g. the static type, circulation, paraffin, copper foam/paraffin) in full and partial condensing heat recovery mode. The results show that in the full condensing heat recovery mode, four systems can obtain relatively high performance, but the systems’ performance rapidly decays with time and can't provide enough cooling capacity and hot water production due to the short running time. In partial condensing heat recovery mode, the four systems’ shows better system efficiency compared with the systems without condensing heat recovery. And the circulation system performance increases significantly, which comprehensive efficiency coefficient can reach 5.67 and the average system heat recovery rate is 44.0%. The two phase change heat storage system run steadily and the adding of foam metal copper to paraffin not only enhance the performance of the system but also improve the stability of the system operation.

能源回收和可持续发展问题迫在眉睫，近年来，空气源热泵中的冷凝式热回收技术得到了长足的发展和应用。本文采用实验方法主要探讨了四种冷凝热回收系统（静态，循环，石蜡，泡沫/石蜡铜）在部分和全部冷凝热回收模式下的性能。结果表明，在全冷凝热回收模式下，四个系统可以获得相对较高的性能，但系统的性能会随时间快速下降，并且由于运行时间短而无法提供足够的冷却能力和热水供应。在部分冷凝热回收模式下，与没有冷凝热回收的系统相比，这四个系统的系统效率更高。循环系统性能显着提高，综合效率系数达到5.67，平均系统热回收率为44.0％。两相变储热系统运行稳定，在石蜡中添加泡沫金属铜不仅增强了系统性能，而且提高了系统运行的稳定性。
