Description

House cooling system based on thermoelectric generation

Technical Field

The utility model belongs to the technical field of the house cooling, concretely relates to house cooling system based on thermoelectric generation.

Background

With the improvement of living standard, people have higher and higher requirements on living places. In order to achieve the purposes that a residential house is warm in winter and cool in summer, people invent an air conditioner. The use of air conditioners requires electricity, which consumes a large amount of energy. Moreover, the air conditioning refrigerant causes pollution and damage to the atmosphere, which is not environment-friendly.

In summer, the house can heat up under the shining of sun, and the temperature of wall body can be than the surrounding environment and go out a lot, because the temperature of wall body is higher than the indoor temperature, so the indoor temperature can be because the high gradual intensification of wall body temperature, and if the air conditioner cooling was opened this moment, the wall body temperature is still very high, can make heat conduction speed grow, increase consumption because the temperature difference grow even.

It was a dream for some to combine thermoelectric generation materials with photovoltaic materials as early as half a century ago. In 1954, pioneer mary tesch uses a thermoelectric power generation material to absorb solar heat and successfully convert the heat into electricity. Electrons released by heat energy on one side of the material flow to the side with lower temperature, so that the side with higher temperature is positively charged, and the side with lower temperature is negatively charged. Tesch successfully generated current in this way, but the efficiency was very low, with only 1% of the conversion in the most successful run. This is not much different from the efficiency of the silicon solar panels at the time. However, by the end of the last 50 s, the efficiency of silicon solar cells has increased by a factor of two, reaching 6-8%. And the efficiency of the solar thermoelectric power generation material is still kept at 1%. Therefore, the new solar photovoltaic industry rapidly abandons the technology, and develops the silicon photovoltaic cell panel, so that the thermoelectric generation material is not dropped. This is associated with the expensive rare metals commonly used for thermoelectric generation materials, in addition to the poor, small efficiency of thermoelectric generation.

Although the photovoltaic cell has a remarkable development speed in the early stage, the photovoltaic cell also faces the bottleneck of the development at present, so people aim at thermoelectric power generation, the thermoelectric power generation utilizes the temperature difference to generate power, can utilize the heat energy existing in the nature, has irreplaceable advantages, and has huge potential in the future despite the problems of high price and low efficiency.
