Description

technical field [0001] The invention relates to a large-scale building curtain wall heat transfer coefficient detection device and method, in particular to a device and method suitable for accurately detecting the heat transfer coefficient of large-scale light-transmitting enclosure structures of various sizes. Background technique [0002] Building curtain wall is an important part of public building envelope. Light-transmitting building components such as glass curtain walls are the weakest link in the thermal performance of building envelopes. The energy consumption of light-transmitting building components accounts for a considerable proportion of the energy consumption of the entire building. [0003] Statistics show that since the beginning of this century, the annual consumption of building curtain walls in my country over the years is the sum of the annual consumption of other countries in the world. With the further development of the economy, more and more glass c...

AI Technical Summary

Problems solved by technology

Poor thermal insulation performance of curtain wall not only wastes energy, but also may generate condensation, which will cause poor indoor thermal environment; poor thermal insulation performance of curtain wall not only greatly increases air conditioning energy consumption, but also affects indoor thermal comfort

The thermal performance of the curtain wall cannot meet the requirements of building thermal design, which will inevitably lead to CO 2 Emissions increase, resulting in urban air pollution, serious waste of building energy, and it does not conform to the national energy-saving policy

[0004] With the continuous development of building energy-saving work in my country, the design standards for building energy-saving are constantly improving, especially for the heat transfer coefficient of large-scale building curtain walls. Therefore, there is an urgent need to develop testing equipment and methods that can accurately test the heat transfer coefficient of large-scale light-transmitting enclosure structures.
