Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a combined solar energy and air energy power generation system and a refrigeration, power generation and heating method thereof. Background technique [0002] The existing power generation systems are mostly thermal power generation systems, hydropower generation systems, nuclear power generation systems and new energy power generation systems. [0003] However, the current conventional power generation systems generally have their own shortcomings, such as thermal power generation, which needs to consume a large amount of coal resources, while the natural resources on the earth are gradually decreasing, and will eventually be exhausted one day in the future, which is not conducive to sustainable development. Moreover, thermal power generation will also emit a large amount of polluting gases, which is not conducive to environmental protection. The hydroelectric power g...

[0003] However, the current conventional power generation systems generally have their own shortcomings. For example, thermal power generation needs to consume a large amount of coal resources, while the natural resources on the earth are gradually decreasing and will eventually be exhausted in the future, which is not conducive to sustainable development

Moreover, thermal power generation will also emit a large amount of polluting gases, which is not conducive to environmental protection

The hydroelectric power generation system is to convert the potential energy of the water held at a high place into kinetic energy to drive the water turbine. It has high requirements on the terrain. It is generally built in the middle and upper reaches of the water system, far away from the load center, and requires long-distance power transmission. The cost is high, and the hydraulic power The power generation system will have a certain impact on the surrounding human environment and other hydraulic systems

Although the nuclear power generation system is a relatively clean energy source, its waste disposal costs are extremely high, and its technical requirements are also very high, which is not conducive to large-scale use. permanent damage
