Nitrogen leak detection is a method to detect whether there is a leak in the air conditioner by injecting nitrogen into the air conditioner system and using the physical properties of nitrogen. Nitrogen is a kind of emotional gas, with colorless, tasteless, non-flammable, non-explosive and other characteristics. After injecting nitrogen, if the air conditioning system does not leak, the nitrogen will stay inside the system and will not leak to the outside, and if the air conditioning system has a leak, the nitrogen will escape from the leak, forming a gas foam or gas flow phenomenon, so that the location of the leak can be determined by observing the foam or gas flow.

Advantages of nitrogen leak detection:

(1) High sensitivity:Nitrogen leak detection has the characteristics of high sensitivity. Because nitrogen is a very inert gas, leaks in air conditioning systems can be detected very quickly. Even small leaks can be detected by nitrogen, thus ensuring the accuracy of the detection.

(2) High security:High nitrogen leak detection has the characteristics of high safety. Because nitrogen is an inert gas, it will not chemically react with other substances and will not cause harm to the human body. Therefore, in the nitrogen leak detection, do not need too much protective measures, will not cause harm to the health of the staff.

(3) Easy and simple to handle:Nitrogen leak detection is easy to operate, only need to inject nitrogen into the air conditioning system, and then by observing the foam or gas flow phenomenon, you can determine the location of the leak, the entire operation process is very simple, does not require too much technical support, nor does it require special equipment.

(4) Low cost:For other leak detection methods, the cost of nitrogen leak detection is very low. Because nitrogen is a common gas, the price is relatively cheap, and in the nitrogen leak detection, only some simple tools need to be used, and there is no need to buy special detection equipment, so the maintenance cost can be greatly reduced.

When detecting nitrogen leaks, it is necessary to select an appropriate nitrogen pressure and flow rate to avoid damage to the air conditioning system. At the same time, when detecting nitrogen leaks, it is also necessary to prevent nitrogen leaks from polluting the environment to protect the environment and human health.
