Weak current College】 【air conditioning copper pipe leakage analysis --- Power By】 【China power house network.

For serious leakage of air conditioning, repair may leak when residual grease stains quickly find leaks. However, if you are not careful observation, without careful analysis of the leakage of simply welding, fluoridation, commissioning, see current normal, refrigeration good think repaired, it will be possible in a short time leak happens again.

In the repair, if you find a leak in joints, but in the whole root of copper pipe and drain dots are small crack shape rather than a dot, then the fault is due to the nearby U-shaped shock absorber pipe caused severe vibration caused by fatigue crack. At this point, you should observe the u-tube at the bottom of shock absorber counterweight is still hanging on it, or fell into the air conditioner chassis. U-tube at the bottom of the shock absorber counterweight has two, mostly bitumen block package in the pipeline, is also useful for rubber mission bundle in the above. Asphalt block counterweight fallen, typically because the u-shaped tube temperature too high. U-shaped tube after losing weight, resulting in severe shook produce fatigue cracking in copper tube and cause serious leaks. Rubber mission but not shedding weight occurring fatigue crack in the copper pipe, because the use of air conditioning in quite a long time after the compressor fixed nut loose, vibration amplitude increase or copper pipe stress. Tighten the captive nuts or appropriate heavier weight block can solve such problems. For asphalt blocks fall down, but also solve the u-tube temperature rise too high, in order to avoid such failures from occurring again.

Typically, the u-tube temperature rise is one of the following reasons: 1. outdoor environmental temperature is too high, such as an awning falls off, away from direct sunlight, near a new outlet of the heat, ventilation, etc. 2. the condenser is not blocked, such as years, cleaning the condenser inlet, dirt, dust or fumes in the air is too heavy, etc. 3. power supply voltage chronically under voltage critical state (180V left and right). 4. pipe system there are other small leakage points. A small amount of fluoride deficiency, causing the compressor running high temperature rise, causing a u-tube temperature is high, especially in warm and cold conditioner of Compressor package with a layer of insulation, lack of runtime compressor temperature rise even more powerful.

Maintenance, according to the specific reasons to take the corresponding measures. Where do the awning, cleaning the condenser, changes in ventilation environment, identify small leakage points, etc. The use of cold and warm south of dual-use air-conditioning can get rid of the insulation layer, then cut into the appropriate width of old tyres volume in his first wife to Office, and small tie wire tied to weight ratio of weight to some of his first wife. And then, under the normal process overhaul, commissioning, observation of the u-tube and other pipeline, if not sway the run properly. In this way, you can ensure that the non-recurrence of the fatigue cracking in copper pipe leakage.
