Description

Technical Field

[0001] The invention relates to the technical field of integrated devices, and in particular to an integrated device for cascaded energy utilization. Background Art

[0002] Solar energy is a widely distributed renewable clean energy source, which is used in the form of photovoltaic power generation, solar thermal utilization and solar thermal power generation. The promotion and utilization of solar energy has reduced the use of traditional fossil energy and is very helpful for energy conservation and emission reduction. Photovoltaic / Thermal System (PV / T) combines solar photovoltaic power generation technology with solar thermal collection technology. It uses fluid to carry away the heat energy generated and unused in photovoltaic panels, and uses this part of heat energy for power generation or heating. This not only improves the power generation efficiency of photovoltaic cells, but also improves the overall utilization efficiency of solar energy, and solves the problem of large floor space occupied by a single photovoltaic or solar thermal component. Heat pump is a type of energy system that can recover waste heat with a wide range of temperatures and can transport low-temperature heat energy to high-temperature heat energy. Studies have shown that the power required for heat pump heating load is much less than direct resistance heating, and the Organic Rankine cycle (Organic Rankine The Rankine cycle, referred to as ORC, is a Rankine cycle with low-boiling-point organic matter as the working fluid. The low-boiling-point working fluid absorbs heat in the heat exchanger and generates steam. The steam enters the expander to do work, and then drives the generator to generate electricity. During use, the low-temperature liquid inside the evaporator of the heat pump system and the pipeline pass through the inside of the photovoltaic panel, taking away the internal heat of the photovoltaic panel. At the same time, the connection between the photovoltaic panel and the pipeline is connected with a rubber pad, forming a loosely sealed space. Because the low-temperature liquid in the pipeline is lower than the temperature of the photovoltaic panel, water droplets will eventually appear on the outer wall of the pipeline, thereby reducing the service life of the photovoltaic panel.
