Q:1 meters metric air conditioner copper tube has multiple (6mm, 10mm, 12mm)?
Depends on what tube, not necessarily, brand-name original machine heavy, market goods are thick, thin, not even copper
Q:How much is the price of GREE 3P air conditioning copper tube? Is it expensive?
If you want to buy it yourself, the pure copper tube will be bought by about 55 kilograms! Regardless of the thickness, of course, the pipe will be less coarse! And it doesn't include insulation, ties, wires, or anything! If air conditioning, then a meter is about one hundred and twenty meters, there is nothing!... Hope to adopt
Q:How much is the air-conditioned copper tube?
Thank you for your attention and support to the air conditioning in the United states!If you want to know the extension tube cost can visit the beauty website www.midea.com or WeChat on "beauty service" query.If there is still any doubt, welcome to the United States enterprises know the question, I wish you success in your work and happy life!
Q:Who knows GREE air conditioning, two pieces of smallpox confidential, match what big copper tube?
9.52 /15.88 has many models, or it may be 6.35/12.7. answered
Q:GREE 3P air conditioner to big diameter tube?
Brass can withstand extreme heat and extreme cold temperatures from 196 degrees to 250 degrees wide application range, and adapt to the drastic changes in temperature (high temperature low temperature and high - Performance), the use will not decrease due to dramatic changes in temperature and long-term use, will not produce the aging phenomenon. This is what ordinary pipe can not do.The linear expansion coefficient of copper tube is very small. It is 1/10 of plastic pipe. It can resist fatigue. At temperature changecopper pipe
Q:Is the air conditioner copper tube folded, affecting the air-conditioning?
It is best not to use, the connection pipe bending easily cause refrigerant leakage, affect the cooling effect! You'd better have a professional air conditioning installation. They will sell you copper tubing in accordance with the distance between your indoor and outdoor machines to avoid waste!
Q:How much is the number of copper tubes needed to install the central air conditioner?
The central air conditioner copper tube needs to calculate the length. Look what type you install. If it is multi - line, multi - tube, you should calculate the distance between each indoor unit and outdoor unit. If you are online with a manifold, you should also calculate the distance between the interior and the interior. Hope to answer some of your help.
Q:If the air conditioner is re assembled, will it damage the copper tube?
Influential。 Depending on the location of the copper tubes, the effect on the air conditioning is different.When the air conditioner indoor and outdoor machine connecting copper pipe bend, air conditioning and refrigeration system piping "pressure loss" will become large, from the compressor working point, variable pressure loss large led directly to the air conditioning compressor capacity output of small systems, such as air conditioning compressor is 2 horsepower capacity, due to internal and external connecting pipe bending machine fold to a certain extent lead to evaporation pressure air conditioning system is reduced, the compressor habit pressure is reduced, the corresponding proportion of the output capacity of the compressor capacity may become smaller, 1.8 horses or even lower number of horses compressor value.When the air conditioner indoor and outdoor machine bending connecting copper pipe to a certain extent, if we can repair the best, it can not be repaired, can only replace the connecting copper pipe or the bending place on both sides are connected by pipe cut to brazing.
Q:Is the diameter of the air conditioner copper pipe inner diameter or outer diameter?
Outside diameter; vernier caliper; 19 better than 16;.16 saves money
Q:How to calculate the taper of square billet mold copper tube?
Should pay attention to the use of approximate formula to calculate the cone half angle a/2, should be: cone half angle is less than 6 degree. Divided by length, the number 28.7 is equal to the degree.Many types of mold, according to the received method saturated solution can be divided into evaporation crystallizer and cooling crystallizer; according to the flow mode liquid circulation crystallizer and slurry denominator (i.e. liquor and crystal mixture) circular mold; according to the operation mode can be divided into continuous crystallizer and batch crystallizer.
