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.

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.
