The use of thermal imagers is especially effective when existing monitoring methods are unacceptable. Let's take such an important problem as detecting heat leakage in buildings. The annual cost of heating homes, institutions, factories, factories, schools, hospitals, etc., both large and small cities is extremely high. Therefore, checking the thermal insulation of buildings is the number one problem. It mainly concerns large cities. It is estimated that about 10% of the annual heating cost can be saved if existing insulation methods are improved. And thermal imaging will help to detect a violation of the thermal insulation of any construction object. In Sweden, for example, thermograms taken with a color film of the "Polaroid" type&They allowed us to accurately determine the temperature distribution throughout the facade, windows and doors, and identify places of heat leakage. The thermal imaging method of building inspection is widely used in construction practice. The same method is used in the development of insulating materials and building elements, as well as in research and development in the field of heat transfer in building materials and structures. And here is another example. A visually cold spot was found on the ceiling of an apartment building. After taking a thermogram of the studied corner of the room, a section of improperly laid mineral wool was revealed on the ceiling. This was the reason for the cold spot on the ceiling. In a number of large cities, the house system is fired off with superheated steam generated by district thermal power plants.
Steam with a temperature of about 200 C enters the heating system of individual houses, where it condenses into water with a temperature of 60-70 C, which is returned to the heating plant via a return pipeline. From time to time, leakage may occur in pipelines caused by internal corrosion and wear of certain parts of the network. The symptom of a leak is an increased loss of water in a closed pipeline network. To determine the location of the leak, the entire pipeline is divided into sections (in this case, the leak can be localized to an accuracy of 500 m). At each end of the dedicated section of the pipeline, a hole of 1 m2 is dug to the depth of pipe laying. Using a stethoscope that detects the noise generated by a leak, first from one end and then from the other end of the section, the leak location can be determined (with an accuracy of 10 m). Then they dig a third hole. The total cost of detecting the location of one leak is quite a large amount.
In the case of using a thermal imager to detect a leak, the whole procedure is reduced to driving a car with a thermal imager installed along the streets under which it is supposed to flow. At first, the approximate location is determined very quickly, and then the exact location of the leak is determined by thermograms. Compared with the usual leak detection method, work using a thermal imager is 6 times cheaper. Thermal imaging will find special application for quality control of finished concrete in reinforced concrete product factories. The following areas of application of thermal imaging in construction can be determined:
1) checking the thermal insulation characteristics of structures;
2) control of reinforced concrete products and structures in the manufacturing process;
3) determination of the accuracy of the joints of reinforced concrete panels with each other;
4) checking the accuracy of installation of elements of buildings and industrial structures, etc. Obtenha acesso rápido e confiável a todos os bônus de cassino sem depósito em
