A solar thermal heating and ventilation system for buildings

Abstract

The invention discloses a solar thermal heating and ventilation system for buildings, which belongs to the field of solar thermal. A solar thermal heating and ventilation system for buildings includes a solar heat collector. The self-concentrating subsystem of the heat collector, the solar heat collector is fixedly connected with a concentrating heat-absorbing plate, and the upper end of the concentrating heat-absorbing plate is connected with a plurality of concentrating bionic flower components distributed in a rectangular array, which can be passed through the concentrating bionic flower components It can effectively collect the sun's rays, increase the intensity of the sun's rays through multiple reflections and focusing, and then effectively improve the heat absorption effect of the concentrating heat-absorbing plate, increase the applicability of the solar collector, and make the solar heating and ventilation system can Normal use in seasons with weak sunlight can effectively increase the penetration rate of solar thermal heating and ventilation systems, effectively improve the utilization of renewable resources, and reduce the continuous loss of non-renewable resources.

Description

technical field [0001] The invention relates to the field of solar thermal, more specifically, to a solar thermal heating and ventilation system for buildings. Background technique [0002] With the continuous improvement of people's living standards, the requirements for the comfort of living and living environment are also getting higher and higher, resulting in the rapid development of building HVAC engineering. In the HVAC system used for heating, natural gas or solar heat is mainly used as the main energy source to heat up the water in the pipeline, so that it can complete the overall heating of the building during the thermal cycle, so that it can be used in colder weather. At the same time, maintain a relatively warm indoor environment and provide sufficient hot water guarantee for indoor living personnel. [0003] The solar thermal system uses solar collectors to collect solar heat, fully converts the sun's light energy into heat energy under the irradiation of sunl...

AI Technical Summary

Problems solved by technology

[0004] Existing solar thermal heating and ventilation systems for buildings use solar collectors to independently absorb sunlight, and then convert it into heat to heat the hot water in the pipeline to complete the collection and utilization of solar heat, but in many areas the sun The intensity of light is greatly affected by seasonality. Therefore, in the season when the sun is weak, the solar collector collects less sunlight, which directly affects its heat conversion efficiency, reduces the heating effect, and then affects the solar thermal heating and ventilation system. System penetration, increased loss of non-renewable energy
