Abstract

The invention discloses a zero-energy consumption building natural ventilation system which comprises a transparent glass cover plate, a heat collecting plate mounted on a south-ward outer wall of the building, and an air way formed between the transparent glass cover plate and the heat collecting plate, as well as an air induction type rotary discharge air cap and an air induction type rotary air intake cap both arranged at the top part of the air way. The natural ventilation system fully utilizes solar energy and wind energy to enhance building natural ventilation capacity, overcomes the deficiency caused by utilizing a single energy source, ensures system stable operation, effectively reinforces indoor ventilation effect to improve the air quality, avoids electrical energy consumption to achieve favorable energy saving effect, and is simple in structure and convenient to install and maintain.

Description

technical field [0001] The invention relates to the technical field of building ventilation, in particular to a system for enhancing indoor natural ventilation by utilizing solar energy and wind energy. Background technique [0002] At present, the proportion of building energy consumption in the total energy consumption of the society is increasing. In my country, building energy consumption accounts for about 30% of the total annual energy consumption, and it is showing a rising trend. However, in building energy consumption, ventilation energy consumption occupies a large proportion, so it is of great significance to adopt reasonable ventilation technology to reduce ventilation energy consumption. [0003] As an energy-saving and environment-friendly passive ventilation and cooling technology, natural ventilation technology has attracted more and more attention. It is energy-saving, environmentally friendly, and can improve indoor air quality and reduce building energy co...
