What to do if the air-conditioning copper pipe leaks

What should I do if the air-conditioning copper pipe leaks? Why is the air-conditioning copper pipe leaking? Everyone is familiar with copper pipes for air conditioning. The material used for the copper pipe of the air conditioner is generally pure copper. The copper content of pure copper is extremely high, so the price of air-conditioning copper pipe is higher than that of other materials such as aluminum pipe. Air-conditioning copper pipe has the advantages of "corrosion resistance, safety and economy", and is a good choice among pipes. Today, I’m going to talk about "what to do if the air-conditioning copper pipe leaks."

　　 Before talking about what to do if the air-conditioning copper pipe is leaking, let's talk about the air-conditioning copper pipe leaking.

　　 1. Reason one for air-conditioning copper pipe leakage: the air-conditioning copper pipe is broken.

　　 2. Reason two for air-conditioning copper pipe leakage: the air-conditioning copper pipe is twisted.

　　3. Cause three of air-conditioning copper pipe leakage: air-conditioning copper pipe joints are not connected properly, causing air leakage.

　　① The defective tube detected by eddy current flaw detection was misused. Under normal production conditions of air-conditioning copper pipes, the eddy current testing of air-conditioning copper pipes not only marks the number of damaged points on each coil, but also paints black marks on the damaged points so that users can identify and pick out this "black pipe" during use. ". Air-conditioning and refrigeration enterprises must make it clear to operating workers, especially new workers. In order to prevent this kind of wounded pipe from being installed on the air conditioning refrigeration device. We have discovered this problem many times when we went deep into the customer service. Some workers asked us what the black color on the tube was, while others were dissecting substandard products because the "black tube" was installed on the product to cause air conditioning and refrigeration. The device is leaking.

　　②The problem of processing. In the process of forming two devices, the air-conditioning main pipe has to go through the links of bending, expanding, flaring and welding. In the process of bending the pipe, the bending part has to undergo local stress, causing local over-extension. Problems such as cracking and dark cracking are formed. Once filled with refrigerant. Refrigerant leakage often occurs here. After the R410A copper pipe of the air conditioner passes through the fin, the pipe must be raised in the pipe expander. The pipe expander is divided into vertical and horizontal types. The vertical pipe expander mainly expands the two devices with relatively small length, and the efficiency is relatively high; the horizontal pipe expander mainly expands the two devices with longer length, and the efficiency is relatively low. In the process of tube expansion, because the core expansion is to increase the size of the copper tube by interference with the inner diameter of the copper tube, the outer diameter of the copper tube is fully in contact with the aluminum foil heat sink. The process of expanding the tube is easy to cause the copper tube to be scratched by the expanding head, forming a penetration injury and causing the copper tube to leak; sometimes the burr penetrates the copper tube when the tube is expanded because the burr in the inner hole of the aluminum foil is too large.

　　③Leakage caused by poor welding. After the copper tube is penetrated into the aluminum foil with holes, the tube and the tube must be connected, and a small elbow connection is required. In order to connect firmly, in the production process, the small elbow and the air conditioner R410A copper tube are welded together with solder , Welding methods are divided into manual and automatic. During welding, due to the quality of the solder, the flaring of the copper tube, and the presence of foreign objects on the welding surface, the welding is not solid, the formation of virtual welding, and the leakage of refrigerant.

　　 What kind of gas is leaking from the air-conditioning copper pipe? The air-conditioning copper pipe is leaking dichloro-phram, which is simply the refrigerant in the refrigeration system.

　　 Is the air-conditioning copper pipe leaking serious? After the copper pipe of the air conditioner leaks, it will affect the use effect of the air conditioner.

　　 What should I do if the copper pipe of the air conditioner leaks? Of course, necessary repairs were carried out after the air-conditioning copper pipe leaked.

　　 1. The first solution for air-conditioning copper pipe leakage: If the air-conditioning copper pipe is not severely broken or twisted, weld and rectify it separately.

　　 2. The second solution for air-conditioning copper pipe leakage: If the air-conditioning copper pipe is broken or severely twisted, replace the air-conditioning copper pipe.

　　3. Solution one of air-conditioning copper pipe leakage: If the air-conditioning copper pipe joints are not connected properly, find professional air-conditioning maintenance personnel to install.

　　 How to detect air-conditioning copper pipe leakage? The sound of air leakage is normal, because the small air-conditioning tube is liquid, and it becomes a vapor-liquid two-phase after throttling and pressure reduction by capillary tube. It is commonly known as "evaporation". This process is the sound of "boom". It is normal for the large tube to form frost caused by the instantaneous pressure drop. Generally, a thin layer of hoarfrost is just right. If the condensation is likely to be the same as Freon, it may be missing. If you think that the sound is not a normal throttling sound, then fill up half a bottle of tap water with a Coke bottle, add more washing powder or detergent, etc., shake out the foam vigorously, make a small eye in the bottle mouth, and spray the foam to the pipe joint If it does not expand, it means it does not leak. If it expands, then it is leaking. The other is to wipe the pipeline clean, and then check if there is any leakage of oil after operation. If there is oil in the refrigeration system, fluorine will inevitably leak, and if there is no oil, it means no leakage.
