Description

technical field [0001] The invention relates to the technical field of heating, in particular to a photovoltaic coupled phase-change heat storage wall panel composite heating system. Background technique [0002] Heating is a building environment control technology. The earliest heating system was the kang, stove, fire wall, fire ground, etc., which were invented by people to resist the cold. The call for emission reduction and the development of a low-carbon economy, the current heating system has a huge space for development in terms of diversification of forms and efficient use of energy; and solar energy, as a renewable energy, is in the case of decreasing fossil fuels. , has become an important part of human energy use, and it also has considerable development prospects in the field of heating. [0003] Solar heating has two methods: photothermal conversion heating and photovoltaic conversion heating; photothermal conversion heating is a technology that uses solar coll...

Problems solved by technology

[0005] During the use of photovoltaic conversion heating, as the surface temperature of the solar photovoltaic panel increases, the output power of the solar photovoltaic panel will decrease. The peak temperature coefficient of the solar photovoltaic panel is about -0.38~0.44% / ℃, that is, the temperature rise High, the power generation of solar photovoltaic panels is reduced. In the hot sun, some parts of solar photovoltaic panels can reach up to 80°C, and it can drop below 0°C at midnight. The high temperature working environment seriously affects the performance of solar energy. Utilization efficiency, huge temperature difference changes will also affect the service life of solar photovoltaic panels

[0006] In addition, in many dry and cold areas, there is less rain in autumn and winter, and the air is relatively dry, forming a weather with low temperature and low humidity. When the heating system is used for heating, as the temperature increases, the evaporation of indoor moisture will be accelerated, resulting in dry skin. Even cracked, which makes people's heating experience very unfriendly
