Truck bed air conditioner is popular in truck drivers to go through the hot summer. But it will be annoyed if the truck bed air conditioner has the problem of air leak. So here are some tips on how to detect truck bed air conditioner leak.

Summer is coming, and the truck bed air conditioners of many vehicles will leak Freon after a long time of inapplicability, resulting in poor cooling effect of the parking truck bed air conditioners, and the truck air conditioning system is hidden in the workbench and it is difficult to detect where the leak point is, and maintenance is very inconvenient. Freon had to be added repeatedly, which polluted the environment not to mention the increased cost. Below we will introduce several leak detection methods for air conditioning and refrigeration systems, hoping to help you.
 

1. Visual inspection for leaks

This method is the simplest and most primitive method, and the leak detection effect is also the lowest. Some very small leaks cannot be found at all, unless there is a large leak point, it is difficult to find.
 

2. Soapy water leak detection

This method is the most common leak detection method in repair shops at present. When the best truck air conditioner system is not disassembled, apply soapy water to all parts of the truck air conditioning system, and the bubbling point is the leakage point. However, some leak points are very hidden, and the internal space of the workbench is very small, and the arm cannot be stretched to apply soapy water inside. In addition, the lines in the workbench are complex and staggered, and the use of soapy water for leak detection may also cause a short circuit of the wires.
 

3. Electronic leak detection

Electronic leak detection is a new type of detection method that has become popular in recent years. During leak detection, the detection probe is moved to the place where there may be leakage. When the leak detection device issues an alarm, it means that there is a large amount of leakage there. However, electronic leak detection is easily affected by the external environment, such as gasoline, exhaust gas, odor, etc., which may cause the leak detector to fail to correctly detect the leak point.
 

4. Immersion detection

This method is often used for the detection of components such as compressors, condensers, evaporators, etc. The specific method is to fill the above components with a certain amount of compressed air, and then place it in warm water of about 50 degrees to observe whether there are bubbles. Use warm water The purpose is to reduce the surface tension of water, because the lower the temperature of the water, the greater the surface tension, and tiny leaks cannot be detected.
 

5. Fluorescent leak detection

It uses the principle that the fluorescent leak detector will emit bright yellow-green light under the irradiation of ultraviolet/blue light leak detection lamp. When using, just add the fluorescent agent to the air-conditioning system in a certain proportion. After the system has been running for a period of time, wear special glasses and ultraviolet lamps for leak detection, and the leak will show yellow fluorescence. The advantages of fluorescent leak detection are that the positioning is accurate, the leak point can be seen directly with the eyes, and it is simple to use, easy to carry, and low maintenance cost.

At present, there are already air-conditioning refrigerants with fluorescent agents on the market, which can be used directly, and potential leaks can be found at any time, without the need to add additional fluorescent agents for detection.
I hope the above methods can help you, so that you can enjoy the cool breeze brought by the air conditioner in the hot summer.
