Many common air conditioning failures, such as poor cooling effect, high power consumption and refrigerant leakage, are caused by non-standard pipeline installation and irregular operation.

Standard installation is the premise to ensure the efficient operation and long service life of air conditioning pipelines. Many common air conditioning failures, such as poor cooling effect, high power consumption and refrigerant leakage, are caused by non-standard pipeline installation and irregular operation.

In the construction process, the bending radian of the copper and aluminum pipes should be controlled reasonably to avoid excessive bending leading to pipe wall deformation and internal blockage. The flared interface must be smooth and flat, matched with high-precision brass nuts to ensure uniform stress and tight sealing. The outer insulation layer should be kept intact to prevent damage and water seepage during installation. In addition, fixed supports and pipe seats need to be installed reasonably to reduce pipeline vibration and friction.

We summarize practical installation skills and common error prevention measures based on industry experience, providing reference for HVAC installers and engineering teams. Standardized construction can effectively improve installation quality, reduce hidden dangers, and ensure the efficient, safe and stable operation of the entire air conditioning system.
