The invention provides a high-efficiency high-temperature heat pump system. The high-efficiency high-temperature heat pump system mainly comprises a heater, an ejector, a cooler, a throttling valve, an evaporator, a gas-liquid separator, a working medium pump and a heat regenerator. According to the heat pump system, high-temperature heat energy is adopted as driving force of the system, and therefore low-grade heat energy is upgraded and improved; the ejector is adopted to replace a compressor, and therefore the heat resistance problem of a compressor coil and lubricating oil in a traditionalcompression type high-temperature heat pump is avoided, and the operation parameters of the heat pump system are improved; and the working medium pump is adopted to increase the pressure of injectionfluid, and therefore the operation stability of the system and the energy efficiency ratio of the system are improved, and efficient comprehensive utilization of the heat energy is realized. 本发明提供了种高效的高温热泵系统，主要包括：加热器、引射器、冷却器、
