Abstract

The invention discloses a system and a method for testing an indoor natural ventilating model of a building. The system comprises a building indoor model, a multi-point pressure load system, a wind velocity measurement system and a flow field display system, wherein the multi-point pressure load system is connected with the building indoor model, and loads pressure in the building indoor model; the wind velocity measurement system is extended in the building indoor model to acquire wind velocity data information in the building indoor model; the flow field display system is connected with the building indoor model to release colored gas in the building indoor model; and flow field distribution of wind velocity in the building indoor model can be displayed by shooting the distribution state of the colored gas. The system tests natural ventilation state parameters through a physical model, and can flexibly arrange house patterns and indoor decorating layout, conveniently arrange various types of buildings and various house patterns, test and evaluate indoor natural ventilation index of the building in various indoor decoration modes, and obtain direct and reliable testing results.

Description

technical field [0001] The invention relates to the field of indoor natural ventilation testing, in particular to a building indoor natural ventilation model testing system and testing method. Background technique [0002] Natural ventilation is an important ecological architectural concept. On the one hand, natural ventilation in building interiors can improve the indoor thermal environment in summer or transitional seasons, take away humid and dirty air, and accelerate the volatilization of sweat on the human body surface, thereby improving the comfort of the human body; On the one hand, natural ventilation can provide fresh and clean natural air without consuming non-renewable energy, which is conducive to energy saving and environmental protection. Natural ventilation in the architectural sense refers to the generation of air flow through purposeful openings under the action of wind and heat pressure. [0003] At present, the evaluation of indoor natural ventilation in ...
