[0002] When humans utilize energy to obtain low-temperature loads for efficient heating, they encounter different resource conditions and different user needs. Accordingly, appropriate technical measures are needed to simplify the equipment, reduce costs, and rationalize performance indices.

[0003] Vapor compression heat pump technology, which operates on the reverse Rankine cycle principle, has the advantage of being able to achieve constant-temperature heat absorption; however, it has the disadvantage that when higher heating parameters are required or deep cooling is needed, the required compressor pressure ratio will increase, which means that the manufacturing cost of this core component, the compressor, will increase.

[0004] In many cases, industrial production requires high-grade heat loads, which are often accompanied by the generation of associated heat at relatively high temperatures. Therefore, achieving efficient and high-value utilization of associated industrial heat in the field of refrigeration / heating presents a technical challenge.

[0028] (2) In terms of process, the circulating working fluid discharged by the compressor 1 is supplied to the ejector 2. The working steam generated by the steam generator 3 enters the ejector 2 through the high-pressure steam inlet. The working steam flows through the nozzle to reduce pressure and increase speed to form a low pressure. The circulating working fluid (refrigerant steam) discharged by the compressor 1 is drawn into the low-pressure zone of the ejector 2. After the two steams are mixed, they flow through the diffuser to reduce speed and increase pressure to form medium-pressure steam and are supplied to the heater 4. The medium-pressure steam enters the heater 4 to release heat and condense. Then it is divided into two paths - the first path flows through the booster pump 5 to increase pressure and enters the steam generator 3 to absorb heat and vaporize. The second path flows through the throttle valve 6 to reduce pressure and temperature and enters the low-temperature heat exchanger 7. The circulating working fluid flows through the low-temperature heat exchanger 7 to absorb heat and evaporate or to be further superheated. Then it enters the compressor 1 to increase pressure and temperature. The external power is supplied to the compressor 1. The high-temperature heat medium provides the driving heat load through the steam generator 3. The heated medium obtains the medium-temperature heat load through the heater 4. The low-temperature heat medium provides the low-temperature heat load through the low-temperature heat exchanger 7, forming a compression-ejector heat pump.

After the two steams are mixed, they flow through the diffuser to reduce speed and increase pressure to form medium-pressure steam and supply it to the heater 4. The medium-pressure steam enters the heater 4 to release heat and condense. Then it is divided into two paths - the first path is discharged to the outside, and the second path flows through the throttle valve 6 to reduce pressure and temperature and then enters the low-temperature heat exchanger 7. The circulating working fluid flows through the low-temperature heat exchanger 7 to absorb heat and evaporate or to be further superheated, and then enters the compressor 1 to increase pressure and temperature.
