碩士 === 崑山科技大學 === 機械工程研究所 === 101 === Our world is facing the challenge of both severe climate change and continuous nature disaster, especially are many people freeze to death in very cold winter or the relief and survival in the disaster area is affected due to power outage. The challenge of nature has gradually affecting the quality of human life and gradually threat to the safety of people's life. Therefore the adequate use of heat and electricity must be fully prepared for every country.
This facility is essential life-support systems for many high latitudes family. In this work, the internal combustion engine cogeneration system is experimented to produce thermal energy and electrical power. The energy retrieve efficiency of this equipment will also be evaluated. The system studied consists of a commercial motorcycle engine, an electric generator and a heat exchanger to recover residual heat from the refrigeration water and exhaust gases.
This cogeneration devices with three control volumes: the energy conversion control volume represents the engine working fluid, combustion gases, and engine alternator; the engine thermal mass control volume represents the aggregate thermal mass of the engine block and most internal heat exchange equipment; and the cooling water control volume represents the aggregate thermal mass of the cooling water and that portion of the heat exchanger in immediate thermal contact with the cooling fluid. Water storage tanks for thermal storage and electrochemical (battery) systems for electrical storage are established. The parametric model provides users with useful information about the cogeneration system performance in response to a building’s electrical and thermal demands. This project presents the model, and the results of sensitivity analyses obtained using the model with an energy economic program.
The temperature varied time for heat exchanger at 35℃ ~ 60℃, exhaust emissions, and energy retrieve efficiency were carried at 3000rpm to 4000rpm, and the loaded value 0 kW to 3.2 kW.
The experimental results showed that the cogeneration device worked twenty-five minutes in rotate speed 3600rpm, and load values 3.2 kW, could provide one household use and energy retrieve efficiency was reached up to 59.8%. By the effect of exhaust gas heat loss at low load, energy retrieve efficiency was reached up to 23.4%, But it will increased, but at a high load will rise to about 60%, but still higher than generally gasoline heat recovery efficiency 25%~30%, higher than 30%.
