Q:The air conditioner can be installed on a brass 1.5 air conditioning on it
A brass and 1.5 Horse Brass can be used with each other.A brass and brass 1.5 horses are the same copper tube is 6 mm, and 10 mm.Copper action:1., the outdoor and indoor machines are connected to the copper tube is used to walk fluorine, fluorine is through this to the room for refrigeration, the external machine is hung under the window, good, clean and easy to maintain.2, air conditioning copper tube (plus insulation cotton) in the exposure to the air-conditioning cooling, but not very big, because the refrigerant cycle is very fast.
Q:What is the mosquito coil copper pipe for?
The application of mosquito coil and copper pipe is quite extensive. Mosquito coil and other coil difference, mainly mosquito coil is fixed length, high-grade packaging.
Q:Can 1P air conditioning use copper tubes with 1.5P air conditioning?
Yes, the.1-1.5 air conditioner, the air pipe and the liquid pipe are all the same diameter, how can they not?Don't worry. It definitely matches,
Q:There's a hole in the copper pipe in the air conditioner. Can you fill it up with something? Twenty
It is better to weld the hole with acetylene welding, that is, it can not be welded and blocked, and it can not leakAsk someone to weld. You might as well find someone who repairs the air conditioner and let them weld it and give you a refrigerant. That's what makes it affordable. The price varies with the level of income in different placesBetween 100---200
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
Q:Why does the air conditioner use a copper tube to deliver coolant?
The small density and soft texture of aluminum pipe can not compare with copper tube in mechanical performance and bending performance.The density of aluminum and copper is different, the cross-section is not the same, and if the aluminum tube and copper pipe are connected, the connection may be unstable welding, easy to cause refrigerant leakage, and may even explode.Aluminum and copper connection easily lead to corrosion of aluminum tubes, resulting in cooling, heating effect worse, and even cause air-conditioning can not work properly.  Due to the different material, half life is almost only copper aluminum pipe, the cooling effect is relatively worse due to bending performance than copper, if consumers want to move again, bending tubes, very difficult, basically need to replace the new pipe.
Q:How long does the Haier air conditioner connect to the brass tube?
It is 4 metres machine cabinet, hang up is 3 meters
Q: what's the size of the copper tube?
You should add extra charge to the specific installation location, but it's expensive!
Q:How do you solder copper and iron? I always weld copper pipes and 3mm thick steel plates. What's the problem?
It's the choice of materialsI don't know what type of welding you are using. The welding of copper and iron can be done as follows1, VOD203 high silver welding wire, work melting point is relatively low, good operation, but the price is relatively high, flame welding
Q:How much is the number of copper tubes needed to install the central air conditioner?
If there are CAD drawings would be well determined first indoor machine tool position and then pull it but not straight along the walls should pay attention to
