Commercial Infrared Thermography Inspection And Energy Audits

COMMERCIAL INFRARED THERMOGRAPHY INSPECTION AND ENERGY AUDITS Thermal Imaging and Energy Audits  Thermal energy, also known as infrared energy, is light that is invisible to the naked eye because its wavelength is too long to be detected. Heat is defined as a part of the electromagnetic spectrum.  Infrared thermography cameras create pictures of infrared or heat that are invisible to the naked eye. Infrared thermography cameras provide non-contact temperature measurement by capturing images of invisible infrared or heat radiation.  Using an infrared camera, we can “see” and “measure” thermal energy emitted by an object forming an image, as well as the temperature of that object. It has become a familiar and successful tool for inspecting and troubleshooting energy and safety issues in homes, businesses, and factories.

HOW THERMOGRAPHIC INSPECTIONS WORK  Infrared thermography, commonly used to identify loopholes in structures, such as electric damages, leakages, and high energy consumption areas has proven to be very useful in emission control and predictive maintenance tools to reduce additional costs.  Infrared thermography inspections are a boon to overall building analysis and play a critical role in addressing complex structural analysis problems. The growth of the infrared thermography market in building inspection has been fueled by the expansion of infrastructure, a population increase, predictive maintenance, and an emphasis on energy consumption rate.  A thermographic inspection is either an interior or exterior survey. Under certain weather conditions, the energy auditor determines which system can produce the best results.

There are many infrared sensing instruments that energy auditors use during their on-site inspection.

The most specific device is a spot radiometer, and it is also called a point radiometer. The spot radiometer only measures the radiations one spot at a time, with a simple meter reading showing the temperature of that spot. The inspector pans the area with the appliance and then records the temperature differences.

A thermal line scanner shows radiant temperature viewed along a line. The line scan is superimposed over an image of the panned region in the thermogram. Temperature variations are visible along the line in this operation.

A thermal imaging camera, which creates a 2-dimensional thermal image of an area showing heat leakage, is the most accurate thermographic inspection tool.
