Natural ventilation system for tall and big space of building

Abstract

The invention discloses a natural ventilation design system for tall and big space of a building. By means of natural ventilation design calculation under the action of hot pressure of the tall and big space, parameters meeting summer indoor air design, the ventilation quantity required for removing building waste heat and residual moisture and the required air inlet window area are obtained. To improve the ventilation efficiency of natural ventilation, an air inlet window is arranged at the place as low as possible, an exhaust opening is formed in the high position to the greatest extent, unpowered rotational flow natural ventilators can be utilized for replacing exhaust side windows on a roof, and the ventilation effect is increased. According to the natural ventilation design system, by means of the windowing area and position setting of the building, natural ventilation can meet the requirement of the indoor summer air design, building energy consumption can be effectively reduced, and environment pollution generated by air conditioner using can be reduced.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of architectural design, and in particular relates to a natural ventilation system that can be used in tall and large spaces of buildings. [0003] 【Background technique】 [0004] In today's world, energy saving has become the theme of the times. my country's building energy consumption accounts for more than 27.8% of the total energy consumption of the whole society, and half of building energy consumption comes from heating, ventilation, air conditioning and related systems. Therefore, the energy consumption of air conditioners It has become a hot issue in the field of building energy efficiency. In particular, the existing large spaces in buildings, such as exhibition halls, gymnasiums, and multi-purpose halls, mostly use air-conditioning systems for air conditioning, ventilation and cooling, and their relatively high energy consumption has become a major contributor to building energy consumption. In addit...

Problems solved by technology

Especially in the existing high-rise buildings, such as exhibition halls, gymnasiums, multi-purpose halls, etc., most of them use air-conditioning systems for air conditioning, ventilation and cooling, and their relatively high energy consumption has become a major contributor to building energy consumption.

In addition, while the air conditioning system creates a good indoor environment, it also brings certain damage to the external environment.
