Passive solar photovoltaic and photo-thermal integrated ventilation power generation system

Abstract

The invention discloses a passive solar photovoltaic and photo-thermal integrated ventilation and power generation system which comprises a buried pipe, a photovoltaic panel heat collector and a chimney, an inlet of the buried pipe is communicated with the outside, an outlet of the buried pipe is communicated with the indoor space, outdoor air can be conveniently introduced into the indoor space, the photovoltaic panel heat collector and the chimney are arranged on a roof, and the chimney is vertically arranged. The photovoltaic panel heat collector is internally provided with an overflowing channel, the two ends of the overflowing channel are provided with an air inlet and an air outlet respectively, the air inlet is communicated with the indoor space so that indoor air can be led into the photovoltaic panel heat collector, and the air outlet is communicated with the bottom of the chimney so that air in the photovoltaic panel heat collector can be led into the chimney. The ventilation power generation system can effectively adjust the indoor temperature and the indoor air quality, improve the power generation efficiency of the photovoltaic panel, and achieve optimal utilization of renewable energy sources in the building field.

Description

technical field [0001] The invention belongs to the technical field of ventilation and power generation, and in particular relates to a passive solar photovoltaic photothermal integrated ventilation power generation system. Background technique [0002] As the earth's fossil energy continues to decrease, the development of renewable energy has become the core content of many countries' promotion of energy transformation and an important way to deal with climate change. It is also an important measure for my country to promote energy production and consumption revolution and promote energy transformation. Solar energy and geothermal energy are two kinds of renewable energy. Solar energy is the most abundant renewable energy in the world; geothermal energy is a new type of renewable and environmentally friendly energy, which mainly comes from solar radiation and gradient warming of the earth. [0003] Solar photovoltaic panel, also known as "solar chip" or "photovoltaic cell",...

Problems solved by technology

However, since the power generation efficiency of photovoltaic panels is inversely proportional to its own temperature, the power generation efficiency decreases by about 0.5% for every 1°C increase, so when photovoltaic panels generate a lot of heat, the power generation efficiency is also declining, resulting in a reduction in power generation
