With the popularization of the concept of energy conservation and environmental protection, energy conservation has become the goal of all walks of life, and the construction industry is no exception. Building energy efficiency management has become a mandatory indicator in many countries and has had a significant impact on many professionals in the construction field. How to reduce the energy loss of buildings has become an urgent problem in the construction field. Infrared thermal imaging camera can accurately locate the specific location of energy loss, and can judge the energy loss of buildings without using any destructive detection methods. It is an ideal tool for construction diagnosis. Let's take a look at the applications of thermal imaging cameras in the construction industry.

1. Detect insulation defects

The typical thickness of the insulation layer varies in different countries. In countries with cold climates, the insulation layer is usually thicker. In countries with temperate climates, the insulation layer is thin or not used at all. On the other hand, in warm weather conditions, indoor spaces need to be cooled, which also requires a thicker insulation layer to prevent energy loss. When using an infrared camera, the temperature difference between the outer wall and the inner wall must be at least 10°C in order to obtain a good, easy-to-view image. Using a thermal imager with higher resolution and thermal sensitivity, the temperature difference requirement will be smaller.

2. Detect gas leakage

It is a common practice to discover gas leaks through the outer structure of the building. Gas leakage leads to higher energy losses, usually causing problems in the ventilation system, and causing condensation in the building, thereby deteriorating the indoor climate. However, with the use of thermal imaging cameras, it is possible to detect the typical phenomenon that occurs when cold air leaks from a building.

3. Moisture detection

Moisture is the most common form of house damage. Gas leaks can form condensate in walls, floors, or ceilings. The damp insulation layer takes a long time to dry and often becomes the main location for mold and fungus breeding. Scanning with an infrared thermal imaging camera can detect the specific damp location that causes the mold to multiply and determine the location of the inherently damp area.

4. Detect thermal bridge

Thermal bridges are areas with less insulation due to the building structure; such as metal fasteners, concrete beams, slabs or columns. Heat will find the most convenient way (the way of least resistance) to escape from the higher temperature space. In many cases, heat will be "short-circuited" through a component that has a higher thermal conductivity than the surrounding material. This component is called a thermal bridge. The thermal bridge can be clearly detected by the infrared thermal imager.

5. Heating pipes and district heating

In areas with cold climates, heat is supplied to roads and passages. District heating is also common. This heating system generates heat at a central point to meet residential and commercial heating needs. Thermal imaging measurement can easily detect any faults in the underground heating system. Even if the ground is covered with snow and ice, the heating pipeline can be seen using an infrared camera.

6. Found that the roof is leaking

When the wet area of the roof can be repaired without replacing the entire roof, huge costs can be saved. By using the sun as a heater, thermal imaging cameras can find the damp insulation on the roof. During the day, the sun heats the roof. At night, the roof cools again, but the area with the moist insulation layer cools more slowly. In the infrared image, this area is clearly visible and the temperature is higher than other areas.

7. Electrical failure

Electrical failure is one of the most common failures in buildings. In most cases, these electrical problems are invisible to the naked eye, but hot spots can be immediately seen on the infrared image with an infrared camera. The user can scan the electrical cabinet and components, and detect a large number of wires and connectors, and immediately clear the problem. Before the problem actually occurs, the problem area can be detected and repaired!

8. Detect floor heating leaks

Infrared thermal imaging camera is an easy-to-use tool, even if the water pipe is laid under the floor or plaster, you can still find out whether the pipe is leaking. The heat of the pipeline radiates outward through the surface of the pipeline, and the thermal image can be easily detected with an infrared thermal imager.

9. Smell

Thermal imaging cameras help find leaks between houses. Leaks between houses result in poor sound insulation and the infiltration of cigarettes and other odors. By using negative pressure and temperature difference, leaks can be easily detected.

10. Cold storage

Cold storage and cold rooms have high requirements for heat insulation and sealing. The normal indoor temperature of cold storage is -23°C to -25°C. Insulation failure and leakage will cause condensation and icing in the building structure, resulting in greater energy consumption-and ice will eventually damage the building structure; infrared thermal imaging cameras can easily detect whether the insulation of the cold storage has failed .

11. Reconstruction plan and quality assurance

Infrared technology is used in reconstruction plans, as well as in quality assurance and the inspection of new buildings. During the drying of the building structure, infrared images can determine the progress of the drying process, so that necessary measures can be taken to speed up the drying process. If the drying process can be accelerated, and with the help of a thermal imaging camera, it is proved that the building structure is completely dry, the building can be delivered to the customer faster.

12. Building repair

Infrared thermal imaging provides valuable information during the restoration of buildings and monuments. The frame structure hidden in the mineral plaster is clearly visible in the infrared image. Therefore, it can be determined whether the exposure of these structures is useful. The separation of gypsum on the wall can also be carried out as early as possible so that maintenance measures can be taken.
