Infrared Thermal Imaging Technology In The Building Structures Study On The Application Of Energy-saving

As China's economic system reform and opening up foreign policy,Building over the past can no longer meet the needs of people's lives,Large energy-consuming and does not heat,Long live all kinds of questions will appear.So the modern building on the energy requirements of more and more high,Energy-efficient building of our country are a long-term national policy,Building energy-saving effect for the detection and assessment of,Emphasis on process control abroad,China also promulgated the regulations and standards.The development of building energy-efficient detection of higher energy-saving building requirements. Energy-efficient building is currently used detection methods can not meet the needs of social development. The main shortcomings are as follows: detection methods and time-consuming, inconvenient Detect operation difficult. In order to meet the requirements of the development of energy-efficient building, this study detected the infrared energy-saving building methods exist other than the current law more quickly and accurately. Infrared thermal imaging with non-destructive testing method, rapid and non-contact, distance, sweep a large area measurement, etc., it is by detecting the distribution of surface temperature field to analyze the internal state of objects. It is a new, sensitive detection methods, is also a good method of monitoring. On building energy-efficient detection of infrared thermal imaging technology to analyze a number of key technologies and research, can promote the application of the technology and development. Infrared thermal imaging technology with its unique advantages in energy saving in building more and more attention. However, in testing methods, results and analysis of such precision, there is still room for more in-depth theoretical and experimental studies.In this paper, heat transfer theory and architecture derived from the calculation of thermal non-steady-state heat transfer of the building envelope under the formula for calculating the heat transfer coefficient. The use of infrared imaging system can rapidly and accurately detect the situation of building energy-saving, come to the heat transfer coefficient of building envelope. With the development of more and more energy-efficient building requirements of rapid and accurate detection of building energy saving, continuous detection of higher energy-saving building requirements. Infrared detection method will have broader prospects.
