Condensing Unit Leak Testing

It is, as a rule, condensing unit, where the printing starts. The reason is that at this unit, leak easier to find and fix. The most important tool technology is his eyes. Follow very closely for signs of oil. Small amounts of oil attract dirt, which make it very visible. Caution should be exercised when handling oil. In some cases, when the compressor would have burned, remember that acid is formed and spent oil. High concentrations of acid can damage the skin. In addition to your regular hand tools, several additional specialty items required for leak testing.

Bottle of nitrogen will be important in some leak testing situations. Remember nitrogen regulator; never use gas without appropriate regulator. Electronic leak detectors are good in isolation close proximity. In some cases, where the concentration of refrigerant vapour is very high, electronic leak detector may be more sensitive to the state and, accordingly, may not pin-point the leak. Halide leak detector. The concentration of leakage will be indicated by the color of the flame.

Difficulties in leak testing with halide you can find on windy days. The wind can carry refrigerant vapor faster than halide leak detector can pick it up. For this reason, I recommend that you have six feet and six feet piece of plastic for the construction and use as a tent. On windy days, the plastic material used to cover the condensing unit. With the addition of the refrigerant pressure parts, in one corner of the plastic and took the hose halide leak detector is placed beneath the plastic. Hose sniffing the refrigerant. Concentration of refrigerant vapors should happen now that the wind may not disperse the refrigerant leakage.

One of the biggest mistakes when using techniques makes halide leak detector is using too large a flame in the fireplace. It is only necessary for the tip flame to touch the underside of the disc detector.

Sometimes, leakage show only at high pressure. This is one of the reasons that nitrogen is used. On the label of the most air conditioning condensing units, the test pressure is noted. This pressure is applied to the device at the factory to make sure that there will be no leaks, defective joints, or materials. When applying pressure nitrogen does not exceed these limits. Working pressure points lower than the ratings on the data plate. Nitrogen must be added to the system until the pressure of the refrigerant that the system will function. With the addition of nitrogen pressure, high pressure, leakage can be detected without the need for devices. Another thing to remember, pressure device on a very hot day will cause pressure units for high pressure operation. You might look for leaks on a cool day, and pressure is not high enough for the detection of leaks.

A product called Leak Detector on the market. He looks like a bubble solution child makes bubbles. If you do not have solutions available to you, the usual soap liquid detergent used in the home enough. When halide or electronic leak detector localize refrigerant leakage, bubbles decisions will shape the exact location of the leak.
