Example Embodiment

[0009] Assuming that the refrigerant used is chlorofluoroalkane CF 3 CHCl 2 (R123). Its thermodynamic parameters are shown in the following table:

[0010] Working fluid

[0011] In one example, the solar radiation intensity is 5040MJ / m 2 , The solar collector 1 is a vacuum tube heat pipe collector with a heat collecting area of ​​74m 2 ,The heat collector heats the heat transfer oil, the heat transfer oil and water exchange heat in the heat exchanger 2, the heat exchanger area is 135m 2 ,The hot water is transported to the evaporator 5 through the pipeline, the heat exchange area of ​​the evaporator is 78m 2 , Heating the low boiling point working fluid R123, the R123 at 25°C will endothermic and vaporize to become saturated steam at 65°C. The steam does work on the steam turbine, and the internal efficiency of the steam turbine is 70%. The output electric power is 1KW, which generates one kilowatt-hour in an hour. The area of ​​collector 3 required to generate electricity fo...

Abstract

The invention discloses a novel solar power generation process. In the daytime, solar energy is used for collecting heat to generate electricity, and redundant heat energy is stored to supply sustainable power generation energy at night or in rainy days. The process belongs to utilization of clean energy, and is free of pollution. The process uses heat storage for replacing electricity storage, and solves the power generation sustainability problem at night or in rainy days through energy storage.

Description

technical field [0001] The invention relates to a solar power generation process and provides a sustainable solar power generation technology. Background technique [0002] Solar energy is an inexhaustible clean energy. In the severe situation of decreasing fossil energy and environmental pollution, it is of great significance to develop and utilize solar energy. At present, the utilization efficiency of solar energy is not high, the highest photoelectric conversion rate is 26%, and there is a problem that the equipment cannot continue to generate electricity at night. Wind power generation also belongs to the use of clean energy to generate electricity, but due to the random fluctuation of wind speed, the grid-connected power of wind power generation fluctuates greatly, which has a great impact on the stability and economy of power grid operation. Therefore, it is urgently needed to seek a new clean and sustainable power generation process. Contents of the invention ...
