Micro-hole permeation-type fresh air preheating solar wall

Abstract

The invention discloses a micro-hole permeation-type fresh air preheating solar wall which comprises a heat collecting and storing system and an air flow conveying system. The heat collecting and storing system comprises a solar wallboard, and an air interlayer is reserved between the solar wallboard and a building outer wall. An air cabin communicating with the air interlayer is arranged above the solar wallboard, and an exhaust opening is formed in the outer wall of the air cabin. A flow guiding board for adjusting the opening degree of the exhaust opening is movably mounted on the exhaust opening. Air inlet holes are distributed in the solar wallboard, and a heat absorbing coating is arranged on the outer wall of the solar wallboard. A sun-shading device is arranged on the outer wall ofthe solar wallboard, and the air flow conveying system comprises a fresh air pipeline. An air valve and an axial flow fan are mounted on the fresh air pipeline, and an air supply opening is formed inthe side wall of the fresh air pipeline. One end of the fresh air pipeline communicates with the air cabin. According to the micro-hole permeation-type fresh air preheating solar wall, fresh air canbe obtained in winter, the appropriate indoor temperature can be kept, and the requirements for energy conservation and the indoor air quality can be met.

Description

technical field [0001] The invention belongs to the field of solar heat utilization and building heating, and specifically relates to a porous permeable fresh air preheating and heating integrated solar wall system, which is used for winter fresh air preheating and indoor heating in classrooms, office buildings, etc., and mainly solves the problem of large-area window opening in winter difficult, poor indoor air quality and other practical problems. Background technique [0002] my country's building energy consumption accounts for about a quarter of the total social energy consumption, and heating and air conditioning energy consumption accounts for 40% to 50% of building energy consumption. Solar energy is an inexhaustible clean energy, so using solar energy to improve the indoor thermal environment of buildings can effectively reduce conventional energy consumption. [0003] The heat load of cold air infiltration is the main part of the heating load in winter, which ofte...

Problems solved by technology

[0004] At present, many scholars have done a lot of in-depth research on the commonly used direct benefit windows, heat collecting and heat storage walls, and additional sunlight room passive solar technologies. The results show that these passive solar heating technologies can effectively increase indoor temperature and reduce heating heat in winter. load, but these technologies are difficult to take into account the improvement of indoor air quality in winter

The existing fresh air heat recovery, preheating and other systems can improve indoor air quality, but the equipment system is more complicated and the investment is higher
