Abstract

The invention discloses a building group wind-heat environment simulation experiment measuring device and method under a quiet wind condition, belongs to the technical field of outdoor wind-heat environment testing, and solves the problem that the existing method for measuring the outdoor wind-heat environment of the building group cannot realize the measurement of the outdoor wind-heat environment of the building group in a quiet wind environment. The device comprises a quiet wind experiment box body, a building group component, a temperature testing system and a wind speed testing system, wherein the interior of the quiet wind experiment box body is an experiment space, the top of the quiet wind experiment box body is provided with an opening, the building group component comprises a building group model and a plurality of electrothermal films, and the electrothermal films are fixedly arranged on southward vertical faces of all buildings in the building group model to simulate heating of the vertical faces of the buildings. The wind-free environment can be provided, the influence of the external environment on the interior of the experiment is reduced, and the experiment result is more accurate and reliable. Compared with a wind tunnel experiment, the experiment operation is simpler, the experiment period is shorter, the manufacturing cost of the experiment device is lower, and an experiment result can be obtained more quickly and accurately.

Description

technical field [0001] The invention relates to a measurement device and a measurement method for a wind-heat environment simulation experiment of a building group under a static wind condition, and belongs to the technical field of outdoor wind-heat environment testing. Background technique [0002] With the development of economy and society and the acceleration of urbanization, the global climate is deteriorating day by day, especially in urban areas, where tall buildings are densely distributed, windy weather is frequent, heat and pollutants accumulate seriously and are difficult to discharge, which leads to intensified air pollution. The heat island effect is intensifying day by day, and the contradiction between rapid urbanization evolution and urban environmental problems is becoming more and more prominent, which greatly affects the economic development and endangers people's health. Therefore, it is of great theoretical and practical significance to study the influe...
