Description

TECHNICAL FIELD

[0001] The present application relates to the field of energy, in particular to a household energy comprehensive utilization system. BACKGROUND

[0002] The primary energy on the earth is gradually consumed, which takes a long time to generate on the earth, but the energy is limited. The use of energy is related to the safety of the country and the nation, the interests of enterprises and individuals. Other alternative natural energy has not been developed and applied because of its low value in exploitation and utilization. Energy crisis directly faces the safety and interests of countries all over the world. Energy is the basis of survival. At present, the use and efficiency of energy by human beings are not ideal, so the energy cost of the country, enterprises and individuals is too heavy. Household electricity consumption accounts for a large proportion of energy consumption. The high efficiency, diversification and self-generation of household electricity can reduce the energy burden of the country, reduce the occurrence of energy crisis and reduce the household expenditure of individuals. Reducing energy consumption, improving energy use efficiency and finding other alternative energy are the necessary trends of people's attention and development.

[0003] At present, air conditioners have become an essential part of people's life in summer. According to the survey, although the growth of the household air conditioner industry has slowed down in China in the past two years, the overall market situation shows that the number of room air conditioners in China has exceeded 270 million, becoming a real air conditioner production and possession country. These household air conditioners not only facilitate people's life, but also consume a large amount of electric energy every day, causing increasingly serious environmental pollution problems.

[0004] As we all know, coal, oil and natural gas are the three main energy sources that human life and production depend on at present, but the continuous consumption of a large amount of energy also makes the three gradually exhausted. It is estimated that the remaining natural gas in the world can be used by mankind for about 200 years, while coal and oil can only be used by mankind for about 100 years. Under such conditions, more and more people turn their eyes to renewable energy such as wind energy, water energy, biomass energy and solar energy. Among them, solar energy is the most extensive natural energy, and many developed countries have begun to gradually promote solar home appliances. At the same time, for some countries and regions lacking electricity, the development of solar home appliances can better solve their urgent problems. The solar energy resources in these regions are often more abundant, so this also lays a foundation for the vigorous development of solar home appliances.

[0005] According to the amount of electricity, the day is divided into three periods: the electricity peak period is 7:00-11:00 and 19:00-23:00, a total of 8 hours; the electricity valley period is 11:00-19:00, a total of 8 hours; the electricity trough period is 23:00-7:00 the next day, a total of 8 hours. The electricity peak price is the highest, the valley is the second, and the trough is the lowest. Even under the action of such price leverage, there still exists the situation that "electricity is short during the electricity peak period, and users are cut off; and during the trough period, the generator is forced to shut down". The idle unit at night in China is 400 million kilowatt hours. In order to solve this huge waste, the state has invested a lot of money to build many energy storage projects, such as: 80 million kilowatts of Shisanling Pumped Storage Power Station built at a cost of 3.731 billion yuan, and 500 million kilowatts of pumped storage power station requires more than 200 billion yuan; now there are heat storage electric boilers, ice storage technology, etc. However, these not only have high investment costs, but also have low efficiency conversion rates. Therefore, how to effectively utilize and utilize the role of trough electricity, and how to reduce the pressure during the peak period is a major national and even global energy project.

[0006] The problem to be solved by the present application is: by utilizing the comprehensive conversion and utilization of natural energy and heating energy in nature, the electric energy generated by the multi-form natural energy comprehensive utilization power supply system of the family is used as a supplementary energy source for household electricity, so as to achieve the purpose of saving energy for the country, self-generating electricity for the family, reducing the use of primary energy, reducing pollution, reducing the family expenses of the individual family, and the multi-form natural energy comprehensive utilization power supply system of the family. Multiple power generation devices can be integrated for use, or can be used alone, which has low cost and simple manufacturing. SUMMARY
