Solar heating and ventilation system for building

Abstract

The invention discloses a solar heating and ventilation system for a building, and belongs to the field of solar heat. The solar heating and ventilation system for the building comprises a solar heat collector, a heat collector self-condensation subsystem matched with the solar heat collector is arranged in a heating and ventilation controller, and a light-gathering heat-absorbing plate is fixedly connected in the solar heat collector. The upper end of the light-gathering heat-absorbing plate is connected with a plurality of light-gathering bionic flower assemblies which are distributed in a rectangular array mode, solar rays can be effectively collected through the light-gathering bionic flower assemblies, the illumination intensity of the solar rays is improved through multiple times of reflection focusing, then the heat-absorbing effect of the light-gathering heat-absorbing plate is effectively improved, the applicability of the solar heat collector is improved, the solar heating and ventilation system can be normally used in seasons with weak solar rays, so that the popularization rate of the solar heating and ventilation system is effectively improved, the utilization of renewable resources is effectively improved, and the continuous loss of non-renewable resources is reduced.

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
