Building multi-energy complementary system driven by fuel cells and solar energy

Abstract

The invention provides a building multi-energy complementary system driven by fuel cells and solar energy. Solid oxide fuel cells are utilized to generate electricity efficiently, waste heat in the electricity generation process is also utilized, and solar energy is introduced into the system, so that natural gas, the solar energy and electric energy in the system complements one another, and consequently, stability of the system is greatly improved, and the using ratio of the natural gas is greatly increased; and the overall electricity generation effect and overall heat efficiency are much higher than a common combined cooling heating and power system. Domestic hot water and an air conditioner water system are isolated, the water quality of the domestic hot water is ensured, and the building multi-energy complementary system driven by the fuel cells and the solar energy has high economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of building energy conservation, and in particular relates to a building multi-energy complementary system driven by a fuel cell and solar energy. The fuel cell especially refers to a solid oxide fuel cell. Background technique [0002] Traditional coal, oil, natural gas and other primary energy reserves are limited, and most of these fossil fuels are directly used by combustion, which not only has limited efficiency, but also inevitably produces a large amount of pollutants. With the rapid development of the global economy and the shortage of fossil energy, the problems of improving energy utilization and protecting the natural environment have become increasingly prominent. At present, my country's building operation energy consumption accounts for about 27% of the total energy consumption of the society. According to the research and practice of the energy industry in the past 30 years, it is generally b...
