Description

technical field [0001] The invention relates to a solar energy utilization system, in particular to a trough-type concentrating high-efficiency solar thermoelectric cooling composite utilization system, which belongs to the technical field of solar energy utilization. Background technique [0002] Energy is the basis for human survival and development. However, during the development of human society, in the past few hundred years, a large amount of non-renewable fossil energy has been consumed, and it will be exhausted soon. Therefore, many countries in the world are vigorously Develop renewable energy, including solar energy, biomass energy, geothermal energy, wind energy, water energy, ocean energy, etc. It is estimated that by 2015, through the development and utilization of renewable energy, the discharge of tens of millions of tons of pollutants will be reduced. Among them, solar energy has the advantages of being universal, harmless, huge, and long-lasting. The radia...
