Description

technical field [0001] The invention relates to new energy sources, in particular to a comprehensive utilization system of solar energy and geothermal energy with the function of inter-seasonal heating and cooling adjustment. Background technique [0002] The sun is a high-quality energy source bestowed by nature to human beings, but it is uneven with seasonal changes. In the hot season, the solar energy is sufficient, resulting in a waste of heat energy. Although the solar energy is available in the cold season, it is colder overall, which is not enough for human daily use, resulting in uneven cold and heat in the four seasons. Geothermal energy refers to the geothermal energy buried in the shallow layer, which basically maintains a constant temperature and can be extracted for human use, providing clean and tidy energy suitable for human beings, but its taste is not high. If these energies are extracted in a fixed area, it is easy to cause the energy extraction in this ar...

Problems solved by technology

After careful analysis and observation, it can be found that the system has the following deficiencies. First, it cannot effectively store surplus solar energy and realize energy utilization across seasons; second, it is difficult to store and utilize energy in large quantities, and multiple Comprehensive utilization of energy, but due to insufficient instantaneous energy storage, it is difficult to convert efficiently, and cannot make full use of energy for long-term and stable utilization
