Abstract

A concentrating photovoltaic and photothermal stable combined heat and power system combining a micro heat pipe and a copper pipe heat collector belongs to the technical field of solar energy heat utilization. The system includes a concentrating photovoltaic and photothermal system, a light collecting type flat plate heat collecting system and a combined heat and power building integrated system.The system mainly combines the micro heat pipe and the copper pipe heat collector, and utilizes the combination of the micro heat pipe and the copper pipe heat collector in the concentrating photovoltaic and photothermal system to improve the heat exchange performance and the electricity generation performance of the system; produced hot water is used for family heat supply in winter, and producedelectricity is utilized by each user after produced electricity is converted by an MPPT steady current inverter; and on the basis, the system is coupled to the light collecting type flat plate heat collecting system, and matches feedback adjustment of a control system to make a whole system still equipped with the certain heat supply capacity under the condition of weak irradiation intensity in winter. Through adoption of the system, the thermoelectricity output stability of the system is improved, the comprehensive utilization efficiency of solar energy is increased, and the regional utilization of the solar energy is promoted.

Description

technical field [0001] The invention relates to a new concentrating photovoltaic photothermal system that combines micro heat pipes and copper tube heat collectors, which makes up for the lack of heat exchange capacity of traditional PV / T systems, and couples the system to concentrating flat plate collectors. The thermal system is used for heating in winter to ensure that the integrated solar photovoltaic photothermal building can still have a stable cogeneration function in winter when the environmental conditions are poor, and it belongs to the field of comprehensive utilization of solar photovoltaic photothermal. Background technique [0002] Solar energy is a kind of clean energy, improving the utilization efficiency of solar energy can alleviate the crisis faced by the current conventional energy shortage. At present, solar photovoltaic power generation technology is highly recognized in the field of solar energy utilization at home and abroad. Generally, the maximum ph...
