Basic Methods For Refrigerant Leak Detection


Each administration technician who is environmentally cognizant must know ways and methods to check for leaks in air conditioners and refrigerators. The increasing expenses of refrigerants, global warming and ozone exhaustion have brought about technicians becoming better leak detectors.

Leakage can happen in all sealed systems. This is because flaws are available at each weld, seam or joint fitting. Indeed, even the best gear of leak detection can fail to detect to a great degree small flaws. In any case, given environmental anxiety, temperature, vibration and time, even these flaws get to be distinctly detectable. This article will reveal insight into some ways and methods to detect leaks in refrigerators.

The vapors of refrigerant are able to stream under layers of pipe insulation, slag, rust, flux and paint. Habitually, the site of the leak is away from the point where the refrigerant gas appears. This is the reason for the importance of cleaning the site of the leak by removing rust, flux, slag and free paint. Grease and oil ought to also be expelled from the leak site since they may contaminate the tips of electronic detectors, which are very delicate.

Diagnosing a refrigerant leak issue is straight-forward, however locating the leak source is troublesome. There are several methods that can be utilized by technicians to find these leaks. Each strategy has its own upsides and downsides. A few methods may function admirably in the location of a leak in certain conditions, yet may not function admirably in another system in altogether unique conditions.

Basic Methods For Refrigerant Leak Detection

There are certain circumstances when it is advantageous to utilize more than one leak detection technique while searching the leak – one to locate the general leakage area and the other to pinpoint the exact location of the leak.

Following are a few methods to detect leaks of refrigerants.

  1. Visual inspection:

In a system, when the refrigerant leaks, the refrigeration oil also leaks. The area surrounding the location of the leak gets stained by this oil. A basic way to detect a leak is to inspect visually the fittings and lines for indications of oil. It may give the general idea about the area of the leak.

  1. Using Soap bubbles:

For locating leaks in a system, a typical strategy is to utilize a soap arrangement. The arrangement will begin to rise in case a leak is available. This technique is helpful if there is adequate weight in the system or if the area where the leak is available is known. It is ideal to utilize a soapy arrangement that is purchased from a supply house. Homemade arrangements can also be utilized. They will function the length of they don’t solidify onto the fittings or tubing and they don’t cause consumption.

  1. Electronic detectors:

Electronic Refrigerant Leak Detectors are the snappiest and easiest to utilization of the three methods. More often than not you will have no idea where the refrigerant is leaking and have to narrow down the conceivable areas. An electronic refrigerant leak detector can get you near the location of the leak and from that point you can get more exact. A portion of the better models will allow to crank up the affectability once you get the area found.

For small leaks you can wrap the speculated area in cling wrap or a rag to attempt and contain the refrigerant. When you unwrap the area, put in the refrigerant leak detector and check whether you get a reading. Keep in mind, refrigerant is heavier than air and it will sink to the ground. It is best to sniff under tubing and compartments when looking for it.

These are state of the art leak detectors and are the most current tool to find refrigerant leaks. They operate on the principle of sound detection. Instead of sniffing for refrigerant gas they tune in for the sound it makes as Freon escapes the system. To utilize a ultrasonic leak detector the system ought to be influenced all together for the refrigerant to leak out and make clamor. Also, the work area must be totally quiet.

Recollect that it is looking for sound and no background commotion is imperative. This is the main drawback to using a ultrasonic leak detector. Not very many auto shops are sufficiently calm to utilize it effectively. Most electronic detectors adequately detect leaks. The working of such detectors must be confirmed by the technician before its usage. There are a few detectors whose sensors should be changed after a certain season of usage. Their working must be tried periodically so that the technician don’t waste their time by using a faulty detector to search the leak.

Basic Methods For Refrigerant Leak Detection

  1. Refrigerant dyes:

Certain dyes can be utilized to detect refrigerant leaks by injecting them into the system. The dye gets blended with the refrigerant oil and the leakage point builds up a dye stain. The area of leak can be located via searching for the dye stained area. Generally, fluorescent and red dyes are utilized.

  1. Ultrasonic detectors:

A sound, having recurrence somewhat higher than normal is discharged when there is a leak of refrigerant. These sound waves can be detected with the assistance of ultrasonic detectors. This strategy gives accurate outcomes the length of there are no different sources within the area of the system that discharge same recurrence sound waves.

  1. Ultraviolet Dye Leak Detectors

This strategy ultraviolet dye is injected into the air conditioning system and in principle ought to escape with the refrigerant. Regularly, an auto shops have a ultraviolet leak detection pack that has all of the tools necessary to finish this task. Generally these packs accompany ultraviolet lamp or ultraviolet flashlight, a dye injector, safety glasses and ultraviolet dye. This technique is the most technically complex of the three and is the messiest. You have to inject the ultraviolet dye into the system and wait for it to leak out. The dye can be muddled and get all over the place. It gets in you’re A/C system, your refrigerant manifold gages and you. However once you shine your ultraviolet flashlight and detect the leak, you usually can see exactly where it is.


Regulations on refrigerant leak detection depicts and administers the correct repair of a leak and appropriate disposal of any refrigerant system which can’t be repaired. These broad prerequisites are in constrain in the United States, as well as several outside nations. The treaties put forward an overall reaction to improving and protecting the planet.

Fast action of refrigerant leak detection is a great importance to the earth. Refrigerant contains gasses that have been distinguished as damaging to the ozone layer and demonstrate a high potential for causing global warming. To agree to environmental standards, many companies are investing in a refrigerant management program to monitor and track hardware usage.

Because of environmental and cost concerns related to refrigerant leak detection, many facilities with systems that utilization refrigerants are relying on refrigerant tracker applications. A refrigerant tracker monitors refrigeration and air-conditioning (RAC) systems and heating, ventilation and air conditioning (HVAC) systems around the clock and instantly detects the location of any leaks. Various reviews affirm that industrial and commercial facilities will have the capacity to save cash each year by using leak detection monitoring systems.
