Abstract

The photovoltaic passive heating wall includes glass plate with photovoltaic cells adhered to the back side, two summer ventilating openings, two winter ventilating openings, heat collecting wall, and DC blower for speeding the airflow in the airflow channel. The photovoltaic glass plate is installed on one frame parallel to the heat collecting wall, two summer ventilating openings are in the upper and the lower part of the airflow channel separately, two winter ventilating openings are in the upper and the lower part of the heat collecting wall separately, and the DC blower is installed in the winter ventilating openings or the airflow channel. The present invention has photovoltaic cells, forced airflow to lower the temperature of the cells and raised electricity generating efficiency, the electricity generating and heating functions and building appearance with fascination.

Description

technical field [0001] The invention relates to a building integrated photovoltaic photothermal (BIPV / T) device for a passive solar house, belonging to the field of solar energy utilization. Background technique [0002] The limitation of conventional energy resources and the increase of environmental pressure have made many countries in the world re-strengthen their support for the development of new energy and renewable energy technologies. Solar energy is a clean, efficient and inexhaustible new energy source, so the governments of all countries regard the utilization of solar energy resources as an important content of the national sustainable development strategy. Among the existing solar energy utilization technologies, passive solar heating technology, solar hot water utilization technology and photovoltaic power generation technology are mostly adopted. Among them, the passive heating wall (Trombe wall) in the passive solar heating technology has the advantages of s...
