Q:Why is the air conditioning copper tube again become "air conditioning purple copper tube"?
The use of air conditioning is also called copper copper copper or copper. The brass tubes inside the air conditioner are usually brass or copper tubes.The difference between a brass tube and a brass tube:1, the thermal conductivity of copper is 338 thousand kcal / m..2, the heat conductivity of brass is 80 thousand Cu / M / s, and the ductility of copper is much better than that of brass.
Q:Air conditioning copper pipe copper recovery price
According to the volatility of copper futures price currently around 45
Q:How do you weld aluminium tubes and copper tubes? Who knows?
If you want to put the aluminum tube and copper pipe welding together the first heating of copper in copper tube to heat directly after the silver brazing welding, never old heating tubes, heating tube electrode has been the plug pipe flaring die. When the slip expansion tube
Q:In the process of using outdoor air conditioning machine after the copper frost is going on,
Experienced maintenance personnel in high-pressure pipeline refrigeration on the ice to see that the air conditioner refrigerant is less, if that is the amount of refrigerant low pressure pipeline ice too much (this phenomenon appears less, if there is great harm on the air conditioning compressor)Whether the air conditioner refrigerant in the normal visual has the following tips:1, on the first one or two minutes at the link of copper, copper pipe small (high pressure pipe) ice, but soon automatic open, less refrigerant inside the machine, but also maintain a certain cooling capacity.2, if the small copper pipe icing for a long time, basically no refrigeration capacity.3, continuous boot to see large copper tube (low pressure pipe), if it is dry, there is no condensation water, refrigerant must be less.4, continuous operation, icing big brass, too much refrigerant, jeopardize the compressor.5, continuous boot, the size of two copper tubes are dew, refrigeration dose basically appropriate.
Q:The air conditioner copper a cold how cold is what causes a
Boot time is short, long time point to see, if the thick tube is not cool, it represents fluoride deficiency
Q:How to renovate copper tubes
After soaking with low concentration sulfuric acid, rinse with clean water and then dry.
Q:Why can the inner spiral copper tube improve the heat dissipation?
Through the increase of the tooth height and the bottom wall thickness, the capacity of the material in the pipe and the contact area of the tube wall can be effectively increased, thereby increasing the heat dissipation efficiency.
Q:Bathroom decoration when the dark pipe with copper or PP hose that kind of good?
I give you a suggestion, the toilet water pipe can be considered with copper pipe, copper water pipe must not, because copper cannot be used to tap water pipe, will be poisoned, or use PPR or PE pipe, environmental protection and safety
Q:1.5 how much is one meter copper tube for air conditioner?
6 R 12 r insulation cost no more than 30 quick money market is now copper 51 yuan a kilo. 80 dollars if you install one meter 5 meters above the 60 meters fast money are cost-effective not including the power line
Q:What is the ratio of the capillary and copper tube in the fridge and freezer?
Horizontal freezer with a diameter of 8mm copper tube coil in general, from the mouth of 5-6cm refrigerator dish in the first circle, and then by ring down plate, each ring spacing of 7cm, about 10cm from the bottom end. The coil is connected to the top of the capillary, the bottom corner opening is connected with the compressor inlet. The coil should be smooth, turn to be accurate, appropriate length of the two parts the card will be fixed on the aluminum coil clamp fixed on the inner wall of refrigerator, without width.The length of the coil: measurement of horizontal freezer freezer wall in a circle circumference; the depth of upper vacated 5CM, at the bottom of the rest of the vacated 10CM, according to the depth of every 7CM disc in a circle, the circle number required coil plus 1 ring (the first circle); the total length of the coil is finally on the perimeter. As measured. The freezer is 1.6 meters, depth of 50 cm.Formula: total length m= (/m-0.15m / 0.07m+ refrigerator freezer depth) /m X - /m perimeter perimeterFor example: the total length of m= (0.5m-0.15m), 0.07m+1.6m X1.6m=10.56mCapillary, no matter how long it is outside the original box, keep the original length, and then the 1.2-1.5m (the length that was buried in the box) is the same as the capillary tube of the specificationThrough the capillary clings to the bottom from the upper angle into the first ring (tube hole should be close to the corner, wearing at the bottom of the capillary and the return pipe are from hole piercing). Such as refrigerated dual-purpose freezer, frozen capillary advanced tube.Compared with the vertical coil pipe has three sideways point: 1, do not waste the corner (not accounted for) refrigerator space; 2, no accumulation of condensed water, so as to avoid the wall decay; 3, running or stopping after the initial boot can effectively avoid liquid hammer compressor.Fast method of self-made refrigerator evaporator and capillary tube!
