What is an AC line set?

When it comes to the AC line set, although it is very common in our life, most people will not notice it, and people will only pay attention to it when the air conditioner leaks or other problems occur.

The AC line set is connects the indoor air conditioner and the outdoor unit. Most areas use insulated copper pipe, and a few areas use insulated aluminum pipes.

The AC copper line set is composed of two pipes. The two copper pipes are respectively larger and smaller. The thick one is called the large pipe and the thin one is called the small pipe. The function is to connect the internal and external units, so that the internal and external units form a closed system, and the refrigerant can be The inner and outer units circulate in a circular flow. Generally, the gas refrigerant is used in the large tube, and the liquid refrigerant is used in the small tube. As for which one enters and which one goes out, it depends on the cooling and heating modes of the air conditioner.

In the heating mode, the refrigerant enters the inner unit from the outer unit through the large pipe, and returns to the condenser and compressor of the outer unit through the small pipe.

In cooling mode, the refrigerant enters the inner unit from the outer unit through the small tube, and returns to the outer unit through the large tube.

The refrigerant transmission work of the copper line set ensures the cooling and heating effect of the air conditioner, so a good AC line set is particularly important in the air conditioning system, which directly affects the experience of people enjoying the cooling and heating brought by the air conditioner.

How to choose the right Mini Split Line Set?

Although the material of the mini split line set includes insulated copper pipe and insulated aluminum pipe, most areas will choose copper pipe. Why?

1. The copper tube has high pressure resistance, is not easy to corrode, and has a longer service life than the aluminum tube

2. The thermal conductivity of refrigeration copper pipes is much better than that of aluminum pipes

3. The welding performance and mechanical strength of copper pipes are far better than that of aluminum pipes.

The only advantage of aluminum pipe compared to copper pipe is that the price is lower than that of copper pipe. If only low price is considered, aluminum pipe is the best choice, but in terms of cost performance and customer experience, there is no doubt that, Still have to chooseinsulated copper pipe, which is also the result chosen by most buyers.
