The utility model relates to an industrial ultra-high temperature heat pump unit. The main refrigerant circulation circuit of the heat pump unit is mainly formed by connecting a compressor, a condenser, a synergist, a main throttling device and an evaporator The main refrigerant outlet of the synergist is also connected with a motor cooling loop, an oil cooling loop and a refrigerant enhancing loop. The Motor cooling loop is mainly provided with a cooler and an ejector, the oil cooling circuit is mainly provided with an oil separator, an oil circulating pump, an oil cooler and a drying filter. The industrial ultra-high temperature heat pump unit of the invention has the advantages of good cooling effect and long service life of the compressor motor, low oil supply temperature of the lubricating oil, avoiding high temperature decomposition, and increasing the supercooling degree of the main refrigerant, the exhaust temperature of the compressor is decreased while the heating capacity is increased. The industrial ultra-high temperature heat pump unit of the invention has high heating water temperature, stable and reliable operation of the heat pump unit.
