Abstract

The invention relates to a measurement device and a measurement method for a simulation experiment of wind-heat environment of building groups under the condition of still wind, belonging to the technical field of outdoor wind-heat environment testing. The invention solves the problem that none of the existing measurement methods for the outdoor wind-heat environment of the building group can realize the measurement of the outdoor wind-heat environment of the building group under the calm wind environment. It includes a static wind test box, building group components, temperature testing system and wind speed testing system, wherein the interior of the static wind test box is an experimental space, and the top of the static wind test box is open. The building group components include a building group model and several Electrothermal film, a number of said electrothermal films are fixed on the south facade of each building in the building group model, simulating the heating of building facades. The application can provide a windless environment, reduce the influence of the external environment on the interior of the experiment, and make the experimental results more accurate and reliable. Compared with the wind tunnel experiment, the experimental operation is simpler, the experimental period is shorter, the manufacturing cost of the experimental device is lower, and the experimental results can be obtained faster and more 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...
