Photovoltaic and photo-thermal integrated heating system and operation method thereof

Abstract

The invention relates to the technical field of energy, in particular to a photovoltaic and photo-thermal integrated heating system and an operation method thereof. The system comprises a photovoltaic power generation module, a photo-thermal module, an electric heating module and a control module. The photovoltaic power generation module comprises a photovoltaic power generation unit; the photo-thermal module is used for absorbing waste heat dissipated by the photovoltaic power generation unit in the power generation process; the photo-thermal module and the electric heating module can be used for heating a medium to be heated. The system has the following characteristics that photovoltaic and photo-thermal of solar energy are combined, so that the energy consumption and the heating cost are reduced; the condensation unit is added to further improve the light energy collection area and power, and is integrated with the heat exchange function of the photo-thermal module to avoid the reduction of the efficiency of the power generation module caused by the temperature, and is used for heating the to-be-heated medium to realize cogeneration; when a medium is electrically heated, electromagnetic heating is used, so that the problems of loss and slow heat transfer caused by contact type heating can be avoided, rapid heating can be realized, and the energy utilization efficiency is improved.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a photovoltaic photothermal integrated heating system and an operating method thereof. Background technique [0002] my country's petroleum, chemical and other industries have the problem of long-distance transportation of raw materials by means of pipelines and other measures, and the transportation of high-viscosity raw materials needs to be carried out at an appropriate temperature. It is difficult to meet the demand through technical means such as heat preservation, so continuous external heating is required. As a clean energy source, solar energy is limited by regional restrictions and weather conditions, with low energy density and low use efficiency. The inventors of the present invention found that: the existing pipeline transportation uses fossil fuel combustion or electric heating, which has the problems of high energy consumption, high cost, and inconvenient outdoor en...
