Solar energy thermoelectricity co-generation and co-supply system

Abstract

The invention discloses a solar energy thermoelectricity co-generation and co-supply system. The solar energy thermoelectricity co-generation and co-supply system is mainly composed of a water system and an electrical power system, which are relatively independent. The main component of the solar energy thermoelectricity co-generation and co-supply system is a solar energy thermoelectricity co-generation component. The structural materials of the component comprise a glass cover plate layer, an air insulation layer, a photovoltaic cell sheet, an EVA adhesive film, a metal absorber plate, a heat exchange tube liquid flow channel, an insulating layer and a packaging base plate from top to bottom. A silica gel spacer supports between the metal absorber plate and the glass cover plate to form the air insulation layer; a high-selectivity heat absorbing coating is sprayed on the metal absorber plate to improve the absorbing efficiency for sunlight. Under the shining of the sunlight, the outermost layer cell sheet uses a photovoltaic effect to transform light energy into electric energy and output to supply power to the outside; longitudinal heat exchange tubes in the metal absorber plate on the lower layer collect energy of the sunlight as solar energy heat collecting tubes and heat generated by the cell sheet heating and transforms the heat into heat of cycle fluid to output, therefore, the energy utilization efficiency is improved to the most extent, and the thermoelectricity co-generation is achieved.

Description

technical field [0001] The invention relates to a solar heat and power cogeneration and supply system which utilizes solar photovoltaic power generation technology and photothermal technology to realize solar heat and power cogeneration. Background technique [0002] Solar collectors have been widely used in energy power, refrigeration and air conditioning, social life, aerospace technology and other fields, but there are many problems in the utilization of solar energy. The low utilization rate of solar energy is the current bottleneck of solar energy utilization. , the reason is not only related to the current development technology, but also related to its single use of solar energy. Solar cogeneration utilizes solar thermal technology and photovoltaic power generation technology at the same time, realizes one machine with multiple functions, and can maximize the utilization efficiency of solar energy. Therefore, it is of great practical value to invent a new module with...
