Supercritical CO 2 is a high pressure system. When adiabatic is boosted, its temperature will rise and it will keep the value of enthalpy. When adiabatic, the temperature will decrease with pressure, and the enthalpy will remain unchanged. When sc CO2 is ejected from a small nozzle and changed from a supercritical state to a gaseous state - it will produce a very significant cooling. This property of supercritical CO 2 causes it to be used for metal cutting for cooling of the workpiece being cut - - It can therefore also be used for the cooling of working fluids during geothermal power generation. In principle, we can pass this sc CO 2

An attribute that adjusts its temperature to control its temperature so that the mixed fluid enters the steam turbine at a temperature higher than the original temperature of the heat storage, increasing the temperature at the inlet of the steam turbine; its "self-cooling" performance can also be used for geothermal power generation. Qualitative cooling: Finally reduce the temperature at the exit of the turbine unit. According to the basic principle of the Carnot cycle, η=1-T 2 /T1, T 2 is the temperature (in K) when the gas leaves the steam turbine, and T 1 is the temperature at which the gas enters the steam turbine. Theoretically, the lower the T 2 is. The higher the T 1 is, the higher the upper limit of system efficiency can be improved. The core design idea of ??deep rock rose is based on the adjustment of the thermodynamic properties of supercritical CO 2 , thereby improving the efficiency of the system's Carnot cycle and increasing the upper limit of geothermal power generation efficiency, so that more geothermal energy can be converted into power generation.
