Abstract

The invention relates to a building outer wall thermoelectric power generation control method and device based on solar radiation daily variation, belongs to the field of building new energy and energy conservation, and solves the problems that in the prior art, a building outer envelope structure thermoelectric power generation technology purely utilizes indoor and outdoor temperature difference, the power generation efficiency is low, and the power generation amount is uneven. According to the application, a plurality of thermoelectric power generation units are arranged on the building outer wall, and through hourly solar radiation analysis of the building outer wall, the maximum average temperature difference between the thermoelectric power generation units in a shadow area and a direct radiation area of the building outer wall and the minimum lead length are taken as control targets; and the building outer wall shadow area thermoelectric power generation unit and the direct incidence area thermoelectric power generation unit are connected in series to form an optimized thermoelectric power generation unit group. Through the power generation control method and device, the building outer wall temperature difference power generation efficiency and the hourly stability of the power generation amount can be remarkably improved, the method and device can be widely applied to the building new energy field such as building outer wall power generation, and support is provided for urban distributed energy system design.

Description

technical field [0001] The present invention relates to the technical field of building new energy and energy saving, in particular to a method and device for controlling power generation based on temperature difference of building exterior walls. Background technique [0002] The basic principle of thermoelectric power generation technology is the Seebeck effect of thermoelectric materials, that is, when two metal conductors or semiconductors with different free electron densities or carrier densities in different temperature environments contact each other, the electrons on the contact surface change from high to low. The concentration diffuses to the lower concentration, and the diffusion rate of electrons is proportional to the temperature difference borrowed. When there is a constant temperature difference between two conductors or semiconductors, electrons continue to diffuse and a stable voltage will be formed between the two terminals. The formula for calculating th...
