Refrigerants leaks are one of the most problematic conditions in the electronics industry. It harms the entire system though sealed. The leakage in the refrigerant system effects by increasing the active duration. It affects both the suction and discharge pressure at high risk. Every year a huge number of people call to repair the leakage system. But it is always better to replace the whole system than repair. Let’s know how to detect refrigerant leak.
There are many reasons behind the refrigerant system, Some of them are:
- The overtime working of the system causes a harmful effect on the system.
- The overtime working creates more pressure and allows the system to leaks through vibrations.
- There are several tubed which are placed inside the system. If a system is used for a long time, or years, it weakens the system and helps to increase the chances of leaks.
- Harsh temperature or environment also affects the system.
Refrigerant leak detection method:
Refrigerant leaks can be marked or identified through some easy methods. But, it should be more convenient to simply listen at first than using more advanced leakage detecting gadgets and if you looking for best refrigerant leak detectors then you can check it by clicking here.clicking here. There are two major ways to detect the leakage.
- Detecting through halide
- Detecting through an electronic method
1.Detecting through halide:
it is the traditional way to detect any leakage in a system. In this system, chlorine is used to identify the CFC and HCFC. A sample tube is used to and urged over a high tempered surface. It helps to collapse the vapour. A gas with a bitter smell is made which is called phosgene. In this method, the flame changes its colour. It becomes bright green from pale blue. If this method is applied under sunlight, it will not effect properly. In this method, a small amount of leak detection as 1 to 1.5 Oz (per year) could be detected. To use this method some provisions must be followed. It also has many limitations and not suitable to use in the modern system due to the presence of harmful chemicals.
2.Detecting through the electronic method:
This method is more traceable and shows more clearly as well as accurate results. It is easy to use also. This system requires a special kind of sampling tube which is to draw air around the system. After that, the air is urged over a tempered platinum surface. When a leaked piece is taken into the probe, it works on the gas and a vivid sound is produced. It can accurately detect leakage as small as 0.1 oz per year. The right position of the leak can be also identified through this method.
There are still a few methods through leakage can be detected. And those are:
1.Leak detection through ultraviolet fluorescent dye:
This kind of detecting process was invented to mark any leakage in the automatic transition. It was mainly for the automobile industry. In this process, a fluorescent kind of dye is filled in the system. Then it is fused with the oil and the mixture is moved by the refrigerant system. If it finds any leakage, it will make a glowing flame when seen from the ultraviolet rays.
2.Leak detecting in an ultrasonic way:
This process needs the system to be extremely pressurized. It works with the extreme frequency of the sound which is made by the amplified system in an electronic way. This system works with a microphone as input and headphones as output from the system.
This is an easy method than others. The fluorescent kind of dye is passed into the system. The result can be seen from ultraviolet rays.
4.Soap bubble system:
It is another easy method. This method can be used in all refrigerants. It is suitable to detect leaks firstly, before using any advanced electronic process.
5.Corona discharging system:
In this method, some air is pushed backwards by an activated electronic surface. It works by separating gases in the system. The gases are separated by the electronic arc, can also be called corona discharge. When the gases are detected, the flow in the electrode is changed. And the change warns that there must be some leakage. It should be the time when the replacement of the system is necessary. This method should be applied regularly and must follow some precautions.
6.By detecting the presence of ammonia:
Detection of ammonia can be done with the use of certain gases. This process also has the characteristic of the changing of the colour of the flame.
7.By detecting the presence of carbon dioxide:
A system which contains carbon dioxide, the leakage detecting process is really easy. Carbon dioxide when works as the refrigerant in a system, the leakage identification can be easily done through the soap bubble process. When a soap mixture is fused with some bromothymol blue, the colour of the mixture will change in yellow if it finds any leakage in the system.
