Zero-energy-consumption BIPV/T method based on photovoltaic photo-thermal comprehensive utilization system

Abstract

The invention relates to a zero-energy-consumption BIPV / T method based on a photovoltaic and photo-thermal comprehensive utilization system, and the method employs a photovoltaic and photo-thermal technology to absorb the waste heat of a solar cell panel, improves the power generation efficiency of a solar cell, recovers the heat energy, and fully absorbs and absorbs solar resources. The non-consumed heat energy is stored and utilized for a short time, a medium time and a long time in a heat storage mode of heat storage coupling of the heat storage water tank and the buried pipe, the problem that medium and short-term heat energy supply and demand are unbalanced is fully solved, and the heat supply demand in winter is met. And the storage battery system in the residence and the surrounding vehicle-mounted storage battery are used for storing and utilizing the unconsumed electric energy. The phase-change material is used for storing heat and cooling when sunlight is sufficient and releasing heat and raising temperature when sunlight is insufficient, and due to the characteristic that the heat conductivity coefficient is small, waste heat of the solar cell panel can be further absorbed, the effects of adjusting the room temperature, keeping warm and preventing cold can be achieved, and the livable degree of a house is improved.

Description

technical field [0001] The invention belongs to the field of new energy, and relates to photovoltaic photothermal (PV / T) cogeneration technology, in particular to a zero-energy BIPV / T method based on a photovoltaic photothermal comprehensive utilization system suitable for single-family villas. Background technique [0002] The traditional systems that use PV / T technology to supply energy to buildings such as villas mostly only use part of the roof area to install PV / T components. However, this method fails to integrate PV / T with the building structure of the villa, and does not fully Utilizing the installable area of ​​the villa, the system capacity usually installed cannot fully meet the heat / electricity load demand of the villa, and the structure is not beautiful enough. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a zero-energy BIPV / T method based on photovoltaic photothermal comprehen...
