Analysis of Organic Working Substance Geothermal Energy Combined Cooling Heating and Power System under the Target of "Double Carbon"
In the case of gradual shortage of traditional energy and increasingly serious environmental pollution,the proposal of the'dual carbon'target is of great significance,and the development and utilization of renewable energy has broad prospects.Nowadays,the use of organic working medium as a circulating medium is the most commonly used geothermal power generation method.Heat transfer through clean organic working medium is not only low cost,but also has strong heat transfer performance,which can make good use of the heat of underground hot water.In budget and covers an area of land than the traditional power generation system.In terms of environment,this system is of great benefit to environmental protection.Compared with thermal power generation,the use of geothermal resources for power generation can save fuel and reduce emissions of CO2,SO2 and other exhaust gases,which is of great significance for promoting the realization of'carbon emissions peak'and'carbon neutrality'.
