Escaping the frustrations of leak detection means recognizing the advantages and disadvantages of all the available techniques.
Over the past few years we have had conversations with hundreds of air conditioning and refrigeration contractors about leak detection. Of these unique individuals, one thing that remains constant are ill feelings toward leak detection.
The past several years have brought great change to the field of Leak detection. Thousands of contractors now utilize ultrasonic leak detectors. But when & how can ultrasonics be used most effectively?
There's no denying it, refrigerant leaks are a headache! It's just a fact of life. We have all spent long frustrating hours searching for leaks. Now pain relief is available, thanks to new technologies that can find leaks more quickly. Modern technologies, however advanced they become, will always require skill and intelligence on the part of the technician using them. A specific leak detection technology can be very effective in certain sit
Efficiency can be measured or defined in many ways. Regardless of your definition, non-efficient systems and processes can seriously effect the economics of any facility. Efficiency can be expressed as the ratio of input power to output power. It is an indicator of the "tightness" of the plant. Input power includes all the power consumed to reach a level of output. Therefore, the higher the input power for the same level of output, the lower the efficiency, and the profits!
Searching for vacuum leaks is fundamentally the same as with air leaks, with one difference: the sound generated at the leak is stronger towards the inside of the system that generates it. Fortunately, that remaining on the outside is strong enough to create a signal that can be picked up in some cases, several feet from the leak.
As the name implies ultrasonic leak detectors detect the ultrasonic sound of a leak. You are probably familiar with the hissing sound a large leak makes. Smaller leaks also emit sound, however the frequency is too high for our ears to detect it. By a process called heterodyning, AccuTrak® translates the ultrasonic hissing sound to a lower frequency where it can be heard through headphones, and leads you to the source. As y
It has been nearly five years since Ultrasonic leak detectors began their rise in popularity in the HVAC/R trade. To many, however, it is still considered the “new” method of refrigerant leak detection. Ultrasonics has proved to be a valuable tool for finding leaks in windy or gas saturated areas. They work by detecting the ultrasonic hissing sound of turbulent gas as it escapes from a leak orifice. The sound is then heard through a headset and viewed on a display. Because this method works by sound, it can detect ANY gas, including vacuum leaks.
No discussion on A/C & Refrigeration leak detection would be complete without a mention of AccuTrak®, currently the most talked about, and intriguing technology available.
With so many leak detectors on the market, where do ultrasonic detectors fit in?
What service technicians are quickly realizing is that no matter what types of claims leak detector manufacturers are making...There is no one product or technology which can find every leak. Each technique has an enemy which can severely hinder performance.
For years ultrasonic inspection techniques have been used in plant maintenance programs to reduce energy costs, and increase equipment reliability. In our daily interaction with those responsible for maximizing plant efficiency, experience shows that many who are using ultrasonics don’t really understand the physical principles behind the operation of these instruments. This can result in a false sense of security, and unrealistic expectations. This article will describe the physical basis of ultrasonic inspection, applications, and comparison to vibration analysis. Hopefully it will help eliminate some of the common misconceptions of ultrasonic technology.
The idea of detecting refrigerant leaks by ultrasound, to you may have seemed a bit far fetched. "Really, how well could it possibly work?" - you may have asked yourself. "I've tried every type of detector there is, and none of them really do the job!", or "I already own three leak detectors, why do I need another one?". Can you hear yourself voicing these very words?
The principle of operation of the AccuTrak® is based on turbulent flow. For a leak to happen there must be an opening in the system that carries a gas or fluid. Normally, these openings are not clean smooth holes, but passages through cracks with many jagged edges and internal chambers. Fluid or gas escaping through an "orifice" like this, is forced into turbulence (random circular-like motions).
