Problems solved by technology

[0005] The present invention solves the problem that the glass curtain wall structure in the existing building does not actively utilize solar energy, and the temperature of the air interlayer between the wall and the curtain wall glass is too high in summer, which causes the heat of the corresponding room to be much higher than that of the ordinary wall room. The problem of increasing the air-conditioning load and the problem of inefficient use of solar heat in summer provides a building-integrated solar comprehensive heat utilization system

Abstract

A building integrated solar energy comprehensive thermal utilization system relates to the solar energy comprehensive thermal utilization system. The building integrated solar energy comprehensive thermal utilization system can solve the problems that a glass curtain wall structure in the existing building does not utilize the solar energy initiatively, the temperature of a non-flowable air spacebetween a wall body and curtain wall glass is excessively high in summer, so the heat of the corresponding room is much higher than the ordinary wall body room and the load of an air conditioner is further increased, and the solar heat in summer can not be effectively utilized. The periphery of a compound solar heat collection component is hermetically connected with the outer surface of a building outer wall, a cavity is formed between the two, a plurality of pieces of heat-absorbing glass are correspondingly arranged on an opening of a planar heat collection frame body, a plurality of hemispherical pits are evenly distributed and punched on the outer surface of the planar heat collection frame body, and a through hole is arranged at the upper half part of each hemispherical pit. The building integrated solar energy comprehensive thermal utilization system fully utilizes the solar energy, integrates the thermal insulation, the heat preservation and the solar heat utilization and realizes the integration of the heat collection component and the building while improving the performances of heat preservation and thermal insulation of the glass curtain wall.

Description

technical field [0001] The invention relates to a solar energy comprehensive heat utilization system. Background technique [0002] With the acceleration of my country's urbanization process, building energy consumption will inevitably increase significantly. Heating energy consumption in cities and towns in northern my country accounts for 40% of the total energy consumption of urban buildings in the country, and is the largest component of building energy consumption. At the same time, since coal is the main energy source for heating in my country at present, the environmental pollution caused by burning coal for heating is also quite serious. In recent years, with the improvement of my country's building energy-saving standards, the airtightness of buildings has been significantly enhanced, resulting in low room ventilation times. The indoor air quality in northern regions is generally poor in winter, and the ventilation problem needs to be solved urgently. Under the du...
