Detailed implementation method:
[0042] First, it should be noted that the structure and process are not repeated unless necessary, and obvious processes are not described. The invention will now be described in detail with reference to the accompanying drawings and examples.
[0043] Figure 1 The energy-carrying internal combustion engine combined cycle heat pump system shown is implemented as follows:
[0044] (1) Structurally, it mainly consists of an internal combustion engine, a compressor, a high-temperature heat exchanger, a high-temperature steam generator, a low-temperature steam generator, a second compressor, a heater, a booster pump, a throttle valve, an evaporator, an injector, a second booster pump, and a second injector; externally, there is an air passage that connects to the internal combustion engine 1 via the compressor 2 and the high-temperature heat exchanger 3, and an external fuel passage that connects to the internal combustion engine 1. The internal combustion engine 1 also has a gas passage that connects to the high-temperature steam generator 4 and the low-temperature steam generator 5 before connecting to the outside. The internal combustion engine 1 also has a cooling medium passage that connects to the outside. The second compressor 6 has a refrigerant vapor passage that connects to the heater 7. The heater 7 also has a condensate pipeline that connects to the low-temperature steam generator 5 via the booster pump 8. The heater 7 also has a condensate pipeline that connects to the evaporator 10 via the throttle valve 9. 10 also has a refrigerant vapor channel connected to the low-pressure steam inlet of injector 11; the low-temperature steam generator 5 also has a steam channel connected to the high-pressure steam inlet of injector 11; injector 11 also has a medium-pressure refrigerant vapor channel connected to the second compressor 6; external liquid medium pipelines connect to the high-temperature steam generator 4 via the second booster pump 12; the high-temperature steam generator 4 then has a steam channel connected to the high-pressure steam inlet of the second injector 13; external heated medium channel connects to the heater 7 and then to the low-pressure steam inlet of the second injector 13; the second injector 13 also has a user steam channel connected to the outside; the high-temperature heat exchanger 3 also has a high-temperature heat medium channel connected to the outside; the evaporator 10 also has a low-temperature heat medium channel connected to the outside; the internal combustion engine 1 connects to the compressor 2 and the second compressor 6 and transmits power.
[0045] (2) In terms of process, external air flows through compressor 2 to increase pressure and temperature, flows through high-temperature heat exchanger 3 to absorb heat and increase temperature, and then enters internal combustion engine 1; external fuel enters internal combustion engine 1, and fuel and air complete a series of processes including combustion and expansion in the cylinder of internal combustion engine 1; the exhaust gas emitted by internal combustion engine 1 flows through high-temperature steam generator 4 and low-temperature steam generator 5 to gradually release heat and cool down before being discharged to the outside; the cooling medium flows through the cooling cylinder liner of internal combustion engine 1 to carry away the discharged cooling heat load; the refrigerant vapor emitted by the second compressor 6 enters the heater 7. The steam undergoes exothermic condensation and then splits into two streams: the first stream flows through a booster pump 8 for pressurization before entering a low-temperature steam generator 5 for heat absorption and vaporization; the second stream flows through a throttling valve 9 for depressurization and cooling before entering an evaporator 10 for heat absorption and vaporization. The steam generated by the low-temperature steam generator 5 enters the ejector 11 through a high-pressure steam inlet. The high-pressure steam flows through nozzles for depressurization and acceleration, forming a low-pressure system. The refrigerant steam generated by the evaporator 10 is drawn into the low-pressure zone of the ejector 11. After the two streams of steam mix, they flow through a diffuser for depressurization and pressurization, forming medium-pressure refrigerant steam, which then enters the second pressure zone. The compressor 6 pressurizes and heats up, and the heated medium flows through the heater 7 to absorb heat and vaporize. The liquid medium flows through the second booster pump 12 for pressurization, flows through the high-temperature steam generator 4 to absorb heat and vaporize, and then enters the second injector 13 through the high-pressure steam inlet. The high-pressure steam flows through the nozzle to reduce pressure and increase speed to form a low pressure. The steam generated by the heater 7 is drawn into the low-pressure zone of the second injector 13. 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 users. The fuel provides the driving heat load through the internal combustion engine 1, the high-temperature heat medium provides the driving heat load through the high-temperature heat exchanger 3, the air and gas carry away the emission heat load through the inlet and outlet process, and the low-temperature heat medium provides the low-temperature heat load through the evaporator 10. Users receive a steam-type heat load. The mechanical energy output by the internal combustion engine 1 is used to power the compressor 2 and the second compressor 6, or the mechanical energy output by the internal combustion engine 1 is used to power the compressor 2, the second compressor 6 and the outside, or the internal combustion engine 1 and the outside jointly provide power to the compressor 2 and the second compressor 6, forming an energy-carrying internal combustion engine type combined cycle heat pump system.
