Solar photovoltaic photo-thermal and heat storage type electric boiler combined power supply and heating system

Abstract

The invention discloses a solar photovoltaic photo-thermal and heat storage type electric boiler combined power supply and heating system. The system comprises a solar module, a water storage tank andan electric boiler, wherein the solar module, the water storage tank and the electric boiler communicate with one another through a water pipe; the solar module comprises a solar photovoltaic panel used for solar power generation and a bottom plate arranged below the solar photovoltaic panel, and a heat exchange pipeline and an air duct are arranged between the solar photovoltaic panel and the bottom plate; the water storage tank communicates with an external water source, and the water storage tank communicates with the inlet end of the heat exchange pipeline; and the inlet end of the electric boiler correspondingly communicates with the outlet end of the heat exchange pipeline and the water storage tank, and an external water outlet is formed in the outlet end of the electric boiler. The solar photovoltaic photo-thermal and heat storage type electric boiler combined power supply and heating system has the advantages that the temperature adjusting range is wide, wherein the boiler outlet temperature range is 110-180 DEG C; the automatic control degree is high, and specifically, output power of the electric boiler is dynamically distributed according to solar radiation intensity;and energy gradient utilization is realized, and specifically, through combined utilization of solar energy and the electric boiler, use of electric power during peak is reduced, and the utilization rate of the solar energy is improved.

Description

technical field [0001] The invention relates to the technical field of green energy application, in particular to a power supply and heating system combining solar photovoltaic light heat and heat storage electric boiler. Background technique [0002] China's energy consumption is too dependent on coal-led fossil energy, so that environmental problems are very serious. In order to maintain the sustainable development of society, my country's energy security must face the pressure of huge resource constraints and environmental degradation. Therefore, it is imperative to develop renewable energy to replace traditional fossil energy. As a renewable energy source, solar energy is an important way to optimize energy structure, reduce environmental pollution, and improve energy supply security in my country through rational utilization and development of solar energy. [0003] Solar energy is an inexhaustible and inexhaustible clean and healthy energy for the earth. It is an alte...
