What should I do if the central air conditioner leaks for no reason

Why does the central air conditioner leak? Is it a flaw in the central air conditioner design, a loophole in the installation process, or improper use? Let’s break it down in detail below.

　　 1. The copper pipe insulation cotton is not wrapped

The indoor pipelines of household central air-conditioning are all made of copper pipes. The temperature of the refrigerant in the copper pipes is very low. If the insulation cotton is not tightly wrapped or the quality of the insulation cotton does not provide good insulation, the pipeline will A lot of condensed water condensed and dripped, soaking the ceiling.

Solution: It is recommended to use some better quality insulation cotton. Copper pipes with different pipe diameters should use insulation cotton with corresponding aperture. When wrapping insulation cotton, be careful not to leave any gap between the insulation cotton and the copper pipe, and ensure that the copper There won’t be any nudity.

　　2, the drain pipe is not properly connected to the indoor unit

　　 The drain pipe is mainly used for the condensate discharge of the indoor unit. When it is connected to the indoor unit, it uses a soft connection and needs to be clamped with a clamp. If the connection is not tight, the condensate will flow out of the gap.

　　 Solution: After connecting the indoor unit and the drain pipe, perform a drainage experiment to ensure that the connection is tight and does not leak.

　　 3. Poor drainage of condensate

　　The condensate drain port of the indoor unit is blocked or the slope of the drain pipe is not enough, which will cause the condensate to drain well and accumulate on the indoor unit's drain pan. When the drain pan is full, it will overflow and wet the ceiling.

Solution: During construction, make sure that the condensate drain slope cannot be lower than 1/100. Before connecting the drain pipe to the indoor unit, check whether the drain port of the indoor unit is dirty or blocked. After the construction is completed, the drain pipe must be filled with water. Experiment to ensure that the condensed water can be discharged smoothly.

　　4, the drain pipe is not insulated

The temperature of the condensate flowing in the condensate drain pipe is low, so it is necessary to pack insulation cotton during construction. In order to save costs, some engineering companies did not wrap the condensate drain pipe with thermal insulation cotton, resulting in condensate on the outer wall of the drain pipe. Condensation, causing water leakage.

　　Solution: All condensate drain pipes must be wrapped with thermal insulation cotton, and the standards and requirements for thermal insulation cotton are the same as those for copper pipes.

　　 In addition, the following points should be paid attention to when installing the central air conditioner:

　　 1. The installation position of the air conditioner must be safe, stable, convenient for maintenance, and well ventilated.

　　2. Different fixing materials should be used to fix the air conditioner according to various wall structures.

　　3. The mounting bracket of the air conditioner must meet the requirements of relevant national laws and regulations, and have sufficient strength, rust and corrosion resistance. At the same time, the size of the mounting bracket matches the size of the footing of the outdoor unit.

　　 4. It is recommended to use expansion bolts to fix; when the strength of the installation surface is insufficient, corresponding reinforcement, support or shock absorption measures should be taken to prevent the normal operation of the air conditioner from being affected or causing danger.

　　5. The horizontal installation of the indoor unit should be controlled within ±1°, otherwise it is easy to cause problems such as poor drainage.

　　6. ​​Pay attention to dust protection when installing the engineering machine.
