Beautiful Banff, Alberta will be the site of this year’s InfraCanada West conference to be held October 1st, 2019. Organizers say it is the only facility maintenance and infra-red imaging conference held in Canada. Infra-red technology is more affordable than ever, and its use is growing. There are numerous useful applications for the devices during the installation, inspection, and maintenance of HVACR systems.

 

Examples include scanning vents and registers to see if the temperatures right, detecting if evaporating units are performing by checking whether the flow is uniform, or whether only some of the coil is working properly.

New cameras are better than ever for helping to quickly find air leaks in ductwork, insulation, and connections between appliances. They reveal temperature differentials that may indicate building construction weaknesses that impact HVAC system performance. And they help troubleshoot fuses, breakers, circuits that are too hot compared to others, connections, belts, bearings, and hoses.  

They are also being used to build credibility. Technicians document existing issues and provide images to customers as support for recommendations. They show the customer the problem visually to secure the work, fix the issue, and then follow up with before/after image comparisons.

Infra-red technology can also save customers money lost to incorrect problem diagnoses. John Anderson provided examples in an article in the ACHR News, including a thermostat believed to be out of calibration because the room felt cold. An infra-red camera revealed that a heat-radiating light switch below the thermostat was the real problem.

In another case a residential customer complained of overheating and was convinced the radiant zone was the cause. An E6 camera aimed at the floor showed that the problem was uninsulated hot water lines, later fixed by the plumber. The radiant system was also blamed by a customer whose garage was too hot in the warmer months. Thermal images showed that the heat was coming from two co-generation inverters that were blowing out 120°F air.

Plumbers are using infra-red for locating hot and cold pipes in walls, verifying water temperatures, damp spots, leaking shower bases, bath seals, finding floor heating wires in bathrooms, locating insulation and energy leaks, and so on.

Registration for the Banff conference is open until September 22. Those interested can find information here.
