题目: Performance analysis and optimization of a reverse Carnot cycle-organic Rankine cycle dual-function system -In the context of Peak Carbon Dioxide Emissions and Carbon Neutrality
内容提要:

Conclusions:(1) The integrated system can realize the integration of reverse Carnot cycle heat pump and organic Rankine cycle power generation, and realize two functions of heat pump and power generation on one unit. (2) For fixed heat sources (such as geothermal energy, solar energy, waste heat energy) can realize continuous utilization throughout the year, maximize the use of heat sources and improve the utilization efficiency of heat sources. (3) The annual benefit is about 40 million yuan, the annual reduction of carbon emissions is about 109,000 tons, and the reduction of carbon emissions creates benefits of about 5.16 million yuan. (4)The thermal performance of the system has been analyzed using the lumped parameter model. The maximum COP and heating capacity are 1.65 and 36.41 kW at the evaporation temperature of -10 ℃. The coupled model has higher accuracy than the lumped parameter model with the maximum error less than 8 %. Prospect:(1) The scale of the system is small, and it lacks industrial, civil and other renewable energy applications. (2) The system should be optimized in depth and the heat exchange equipment matching with working fluid should be considered. (3)Calculate the carbon emissions of different systems and their potential to save energy and reduce emissions
