Solar energy utilization system for buildings

Abstract

The invention discloses a solar energy utilization system for buildings, comprising a solar energy receiving system, a photovoltaic conversion system, a living hot water system and a heat energy refrigeration and heating system, wherein the solar energy receiving system converts the solar energy of the building into electric energy and heat energy; the photovoltaic conversion system inverts direct current into alternating current used in the building; the living hot water system converts the heat energy into living hot water which can be continuously used in the building; and the heat energy refrigeration and heating system takes the heat energy as a power source for refrigeration and heating in the building. The solar energy utilization system for buildings can utilize the energy on the building caused by sunlight illumination to the maximum degree, respectively extracts the solar energy, meets the requirement of the building on the energy by two modes of combining photovoltaic power generation and heat generation, and meets power supply, living hot water and refrigeration and heating function in the building. The photovoltaic power generation can be consumed through the electric load of the building and cannot be exhausted, and also can be conveyed to a power grid to meet other requirements, so the optical energy conversion efficiency is greatly improved.

Description

technical field [0001] The invention relates to a building solar energy utilization system, which belongs to the technical field of solar energy utilization. Background technique [0002] As an inexhaustible and inexhaustible energy source, solar energy is rarely used in buildings. In the period when photovoltaic technology was not widely used, people just used solar energy to directly heat water to meet the needs of simple daily hot water. The way to directly heat water is solar water heaters, but the application of solar water heaters is relatively single, only to meet the needs of domestic hot water, and it is only used in the limited space on the roof of the building. Most of the parts of the building that receive sunlight are still vacant and wasteful. great. With the advancement of photovoltaic power generation technology, photovoltaic power generation has been widely used in buildings, but this technology can only meet the building's demand for electric energy, and ...

Problems solved by technology

The way to directly heat water is solar water heaters, but the application of solar water heaters is relatively single, only to meet the needs of domestic hot water, and it is only used in the limited space on the roof of the building. Most of the parts of the building that receive sunlight are still vacant and wasteful. great

With the advancement of photovoltaic power generation technology, photovoltaic power generation has been widely used in buildings, but this technology can only meet the building's demand for electric energy, and the efficiency of photovoltaic power generation is only about 20%. About 80% of the solar resources occupied are wasted
