Application Of Infrared Thermal Image Technology In Detection Of Construction Thermal Performance And Quantitative Analysis

Along with the infrared technical rapid development,infrared thermal image technology is widely applied in nondestructive testing.This article in view of the detection of construction thermal performance need which grows day by day, proposed to the large-scale residential district,the architectural complex carries on the thermal performance examination of the infrared picture direct-viewing picture and the quantification analysis unifiesDevised in view of above that, I successively has carried on two main correlations tests and the experiment.Firstly funded by the project in European Union:Long-enduringdevelopment municipal housing construction--further strengthens the Xiaan policyformulation and implementation system, passed through the line of infrared picture survey to the Xi'an typical residential building,summarized in the scene examination to be possible to use the construction question which the infrared thermal imaging device can diagnose,and proposed test existed question and influence factor.Then propose when survey wall surface infrared picture,the passable division grid, separately has surveyed,again spells pastes the full infrared thermal picture picture, enhances the veracity of the survey. And produce the precision measuring infrared picture surface temperature formula,solved the difficulty of surveying the big area wall surface temperature distribution.Outside initially explored in the hot picture quantification analysis foundation,proposed the use infrared surveyed in the construction energy conservation appraisal,the two important targets,wall heat transfer coefficient and average heat flow density,may figure out the entire outer wall the heat consumption, Method is feasible.Resultsatisfies the measuring accuracy request.Thus, during of the construction energy conservation appraisal,we may fast effective to the large-scale residential district,the architectural complex carry on the examination of the direct-viewing picture and the quantification analysis unifies,which is rapid fast and comprehensively judges in the architectural complex constructs the wall or roof the thermal working flaw situation,thus provides one feasible simple method for the construction energy conservation effect appraisal..
