Level utilizes.Meanwhile another part waste heat can also be directly output to First Heat Exchanger, therefore, three shown in Figure 12 by prime mover
Co-feeding system, in addition to it can produce electric energy, heat energy, additionally it is possible to the energy is produced by energy resource system, so as to improve energy
Source overall efficiency.In addition, the output end that can also control prime mover by current divider is inputted to ORC system and First Heat Exchanger
Heat energy ratio, so as to adjust hot and cold, electric ratio in appropriate scope so that final output it is hot and cold, electric
In zone of reasonableness.
It should be noted that prime mover 10 in the utility model embodiment can use it is any type of in the prior art
Prime mover, for example, prime mover can be internal combustion engine, gas turbine etc..
Organic Rankine Cycle ORC system 30 in the utility model embodiment can use ORC system of the prior art,
For example, ORC system 30 may include but be not limited to the 4th heat exchanger 301, turbine 302, regenerator 303, condenser 304 and work
Matter pump 305, wherein, the input of the 4th heat exchanger 301 is connected with prime mover 10；The output end and turbine of 4th heat exchanger 301
302 connections；The output end of turbine 302 is connected with energy device 50 and regenerator 303；The output end and condenser of regenerator 303
304 input connection, the output end of condenser 304 is connected with the input of working medium pump 305, the output end of working medium pump 305 and
