Photovoltaic window power generation and heating system

Abstract

The invention relates to a power generation heating system with a photovoltaic window. The power generation heating system comprises the photovoltaic double-layer window, a heating system and a power generation system, wherein the photovoltaic double-layer window is of a sealed hollow structure formed by a photovoltaic panel and Low-E glass through a glass framework. A circulating working medium brings residual heat energy generated after the photovoltaic panel generates power into a water tank through the sealed hollow structure. The heat energy in the water tank is used for carrying out indoor heating in winter by terrestrial heat pipelines and for supplying heat to buildings in summer. The power generation heating system with the photovoltaic window can meet the day lighting requirements of traditional windows and meanwhile can solve the heat insulation problem of house interiors. The power generation heating system with the photovoltaic window supplies heat while carrying out photovoltaic power generation and can greatly reduce the indoor energy consumption of buildings.

Description

technical field [0001] The invention relates to the field of environment-friendly and energy-saving solar building integration, in particular to a photovoltaic window power generation and heating system. Background technique [0002] The thermal insulation effect of traditional building windows is very poor, and it is hot in summer and cold in winter; in recent years, with its increasingly mature technology, photovoltaic systems are gradually expanding their development in the construction field, forming a lot of solar building integrated technologies. [0003] At present, domestic photovoltaic windows (such as patent CN 302056150) can play a role in power generation, but due to their high surface temperature, their photoelectric conversion efficiency is low, thereby affecting their power generation efficiency, and the overall cost of power generation is too high. Secondly, after photovoltaic panels generate electricity, a large part of heat energy will be lost, thereby redu...
