Partial coverage type photovoltaic and thermocatalytic combined Trombe wall

Abstract

The invention discloses a partial coverage type photovoltaic and thermocatalytic combined Trombe wall. The Trombe wall comprises a high-light-transmission glass plate, a metal heat absorption plate, a coiled pipe and a heat insulation wall body, wherein a thermocatalyst coating A is attached to the outer side surface of the metal heat absorption plate; the high-light-transmission glass plate is obliquely arranged, and the upper end of the high-light-transmission glass plate is inclined towards the indoor direction; a plurality of solar photovoltaic cell modules are embedded in the high-light-transmission glass plate; the metal heat absorption plate and the heat insulation wall body are vertically and adjacently arranged, an air flow channel is formed between the outer side surface of the metal heat absorption plate and the inner side surface of the high-light-transmission glass plate, and the inner side surface of the metal heat absorption plate is tightly attached to the coiled pipe installed in the heat insulation wall body. The Trombe wall has the beneficial effects that the Trombe wall has multiple functions of heating, ventilation, air purification, power generation, hot water supply and the like, the multiple functions can be switched over, and compared with a traditional solar heat collection wall, the partial coverage type photovoltaic and thermocatalytic combined Trombe wall can achieve the purpose of efficiently utilizing solar energy in multiple stages.

Description

technical field [0001] The invention relates to the technical field of solar building integration, in particular to a partially covered Trombe wall combining photovoltaic and thermal catalysis. Background technique [0002] In September 2020, China announced at the United Nations General Assembly that it will strive to reach the peak of carbon dioxide emissions by 2030 and strive to achieve carbon neutrality by 2060. This is China's first long-term climate goal after the Paris Agreement and the first One mention of carbon neutrality. In order to achieve this goal, it is necessary to continue to make unremitting efforts in energy saving and pollution reduction. Building energy consumption accounts for a large share of China's energy consumption and carbon emissions. From the beginning of construction to the end of the building and then to the end of use, a huge amount of energy will be consumed, and a large amount of carbon dioxide and pollutants will be emitted. In additio...

Problems solved by technology

However, the traditional Trombe wall only converts solar energy into heat energy and only uses it for heating, the utilization efficiency of solar energy is relatively low and the function is single

For this reason, someone proposed to directly install external, central, and built-in solar photovoltaic panels in the Trombe wall, that is, a Trombe wall structure integrating photovoltaic power generation and heating and ventilation, so as to realize the multifunctionality of the Trombe wall, but these Trombe walls There is still a great potential for improvement in function and solar energy utilization effect, especially in summer operation mode, there is a problem of poor operating economy
