What are the two copper branch pipes of the air conditioner?

The air conditioner parts of copper branch pipe are high-voltage pipes and low pressure tubes.These two copper pipes play a vital role in the air conditioning system. They are responsible for connecting indoor and outdoor machines to ensure that refrigerant (Flion, commonly known as snow species) can circulate between the two. Specifically, the thicker copper tube is a high pressure tube, and the thinning copper tube is a low pressure pipe. The effective operation of these two pipelines is the key to air-conditioning refrigeration or heating cycle.

High-pressure pipes (thicker copper pipes) mainly circulate cold media. In the refrigeration mode, after the indoor machine absorbs the indoor calories, the refrigerant becomes a low -pressure medium temperature state, and then out of the outdoor machine through the high pressure tube. Because the refrigerant becomes a high temperature and high pressure state after being compressed in the compressor, it will feel cold when touching this pipe, and there may be water droplets on the surface.

The low-pressure pipes (thinning copper pipes) mainly circulate the liquid refrigerant. In the refrigeration cycle, after the liquid refrigerant passes through the flow valve, the volume suddenly becomes larger, making the refrigerant instantly become a low-temperature and low pressure state, thereby absorbing heat. This pipeline passes the venue valve before entering the indoor machine, such as a capillary copper pipe or an expansion valve to ensure that the refrigerant can effectively absorb heat in the indoor machine to achieve the effect of refrigeration.

The correct installation and connection of these two copper branch pipes is essential for the normal operation of the air conditioner. If the air conditioner parts of copper branch pipe drips water, it may be caused by the aging of the valve, the insufficient refrigerant, the inadequate emissions of the condensed water, or improper installation. Therefore, regular inspections and maintenance of the air-conditioning system to ensure that the connection between the two copper pipes is tight and leakless. It is an important step in maintaining the efficient operation of the air conditioner.‌
