A climatic environment chamber for building envelope thermal performance testing

Abstract

The invention provides a climatic environment chamber for building envelope thermal performance testing. The climatic environment chamber comprises a generating chamber, a control chamber and a collection chamber, wherein the control chamber and the collection chamber are adjacent to the generating chamber. The generating chamber is used for providing an outdoor climatic environment in terms of temperature, relative humidity, wind speed and direction and solar radiation intensity for a building scale model of a building envelope in a test chamber. The generating chamber comprises an air accumulation section, an air processing section, the test chamber, a diffusion section, a fan section and a motor section, which are connected successively. The control chamber is used for controlling the temperature, relative humidity, wind speed and direction and solar radiation intensity in the test chamber. The collection chamber is used for collecting thermal performance data of the building scale model in the test chamber and displaying and outputting the thermal performance data after processing. The chamber can comprehensively simulate outdoor climatic conditions and test the influence of outdoor climatic conditions on the thermal performance of a building envelope.

Description

technical field [0001] The invention relates to a climate environment chamber used for thermal performance testing of building enclosure structures. Background technique [0002] Building energy consumption has accounted for more than 20% of the total energy consumption of the society, becoming one of the three major energy consumption alongside industrial energy consumption and transportation energy consumption, and it has risen sharply with the improvement of the total number of buildings and people's living standards. Among them, the heat consumption of the envelope structure accounts for more than 70% of the energy consumption of the entire building, so the thermal performance of the envelope structure is the decisive factor affecting the energy consumption of the building. With the continuous development of building energy conservation work in our country, the design standards of building energy conservation continue to improve, and the outdoor and changeable weather co...

Problems solved by technology

[0004] The application of the existing artificial climate environment chamber is mostly concentrated in the field of indoor environment detection, which is used for the research on the release of chemical pollutants from indoor building materials and articles, and all of them are single or combined simulations of outdoor climate parameters, that is, single simulation Temperature, relative humidity, solar radiation intensity, wind speed, wind direction or combined simulation of temperature and humidity, wind speed and wind direction, etc., without comprehensive simulation of outdoor climate conditions (temperature, relative humidity, solar radiation intensity, wind speed, wind direction), it is difficult to truly reflect the outdoor environmental conditions
