How to find air conditioning refrigerant leakage

leaking air conditioning fluorine check method

1. Fluorescent leak detection, it is using the fluorescent leak detection agent in the uv/blue light leak detection and so on have a bright yellow green principle, for all kinds of fluid leakage in the system for testing, but everything used PAG lubricant used in the early years of the compatibility with everything is poorer, due to the leakage place hard soil, fluorescent leak detection agent also lost.

2。 Soapy water leak detection, i. e. , bits of filling the pressure to the system. 98 - 1. 96 mpa of nitrogen, and then in each part of the system with soap and water, bubble point is the leakage point.

3。 Halogen leak detection, leak detection after the light, the air on the handheld halogen lamp tube line near the refrigeration system, when the pipeline leakage, flame color becomes purple blue, use this method to leak detection with open fires, more dangerous, and flame combined with refrigerant will produce harmful gases, moreover also difficult to accurately locating funnelled.

4。 Leak detecting device of electron leak detection, the probe to the possible leakage parts move, if leak detection device alerts, show here are leaking.

5。 Section pressure test, that is, making special joint jig, and then to various devices, pipeline pressure test respectively, it is a more reliable method of leak detection.

2: air conditioning how to add fluoride

1. With fluorine filling hose, pressure gauge and fluorine refrigerant cylinders, tube and the air.

2。 Start the compressor, the use of the cylinder and the pressure difference between supplementary refrigerant refrigeration system.

3。 Fluorine filling observation gauge pressure change in the process, make it remain at 0. 45 ~ 0. 5MPa。

4。 Test run after 30 minutes, observe whether air conditioner into normal operation state.

5。 Review the leak suspects after downtime, no leakage can be put into operation.
