Embodiment Construction

[0011] Shown in accompanying drawing 1, groundwater is proposed by water-lifting well 1, is sent into roof solar thermal storage greenhouse 3 (or ventilated sunshade room 4) through insulation water pipe 2, and enters in thermoelectric generator 5 (seeing Fig. 2), and this water flows through The cold collector (or heat collector) 6 transfers the temperature of groundwater lower (or higher) than the ground ambient temperature to the cold-absorbing end (or heat-absorbing end) of the thermocouple chip 7; meanwhile, due to the heat-absorbing device (or The cold absorber) 8 has passed the temperature of the environment to the heat-absorbing end (or cold-absorbing end) of the thermocouple, so the temperature difference between the two ends of the thermocouple chip is the difference between the temperature of the groundwater and the ambient temperature. According to the characteristics of the thermocouple, the thermocouple chip generates electric energy and performs work. The temper...

Abstract

The invention relates to a coupling electric generation system, which makes full use of 1, generation characteristic of thermocouple, 2, the thermal difference between the temperature of groundwater and the temperature of surface atmosphere, 3, 1KW solar energy obtained on the light vertical face per square meter, 4, huge energy in abundant groundwater. In summer higher temperature on the absorbing heat end of thermocouple is maintained by solar energy and lower temperature on the absorbing cold end of thermocouple is maintained. Partial solar energy is transmitted to electrical energy to do work and another partial solar energy is stored in groundwater. In winter huge energy stored in groundwater is used to maintain higher temperature on the absorbing heat end of thermocouple and lower temperature on the absorbing cold end of thermocouple end is maintained by the surface air with lower temperature. Partial energy in groundwater is transmitted to electrical energy and another partial energy is transferred in surface air again.

Description

technical field [0001] The invention relates to a method for generating electricity using solar energy. technical background [0002] More than 180 years ago, the phenomenon of thermocouple power generation was discovered, but it has not been used mainly for power generation, because the figure of merit of the material at that time was too low. The current figure of merit has reached 3.5*10 -3 / K. Therefore, thermocouples have been widely used in electronic refrigeration products. And due to the rapid development of semiconductor materials, the thermal efficiency of thermocouple materials has reached 10% and is constantly improving. The invention uses coupled solar energy to maintain the temperature difference between the two ends of the thermocouple chip, so that the thermocouple power generation can truly function, thereby solving the problem of energy shortage in the world. Contents of the invention [0003] The coupled so...
