1. The refrigerant in the air conditioner absorbs heat in the evaporator, and then transmits it to the compressor through the copper tube, and then dissipates heat through the condenser, and returns to the evaporator cycle. The thermal and electrical conductivity of the copper tube can ensure the transmission efficiency of the refrigerant, so that the air conditioner can achieve better cooling effect.

2. Advantages Copper pipe refrigeration has the following advantages (1) Good thermal conductivity The thermal conductivity of copper is 5-10 times that of other common metals, and it can quickly transfer the heat in the refrigerant. (2) Good electrical conductivity The electrical conductivity of copper is 2-3 times that of other common metals, which can ensure the normal operation of the internal circuit of the air conditioner. (3) Corrosion-resistant copper is not susceptible to corrosion and oxidation, and can ensure the service life of air conditioning. 1. The main reasons for the failure of copper pipes are as follows: (1) Corrosive refrigerant and moisture in the air conditioner will corrode the copper pipes, resulting in thinning or holes in the copper pipes. (2) Extrusion Because the copper pipe in the air conditioner is a long shape, it is easy to be deformed or broken by external extrusion. (3) Aging After long-term use, the copper pipe will produce aging phenomenon, cracks or hardening and other problems.

2. Solution If the copper pipe is faulty, take appropriate measures based on the actual situation. (1) Replace the copper pipe. If the copper pipe has holes or cracks, replace the copper pipe. (2) Repair of copper pipe If the copper pipe only has some small cracks or deformation, it can be repaired by welding or strengthening. (3) Preventive measures In order to avoid the failure of copper pipes, some preventive measures can be taken, such as regular cleaning of air conditioners, reducing the corrosion of water in the air on copper pipes, and avoiding the extrusion of external forces on copper pipes. Copper tube refrigeration is one of the main refrigeration methods used in air conditioning, which has the advantages of good thermal conductivity, good electrical conductivity and corrosion resistance. However, the copper pipe will also appear corrosion, extrusion, aging and other problems, need to take corresponding solutions or preventive measures. Only by maintaining the good condition of the copper pipe in the air conditioner can the normal operation and service life of the air conditioner be guaranteed.
