The copper of the refrigerator, the evaporator and the liquid pipe is, oxygen-free copper, and the copper of the filter Most of the refrigerator evaporator is made of steel pipes and aluminum plates;Most of the liquid adding pipes (process pipes) on the compressor are copper, the filter is small copper, and the larger is steel;If it is made of copper, it is oxygen-free copper. You know that there are almost no brands of refrigerators that use copper tubes as evaporator, except for a batch of Okuma refrigerators. other useless ones. Other copper pipes, such as filters, are mostly not oxygen-free copper. The cost is too high. The pipeline of the refrigerator and the material of the filter are basically copper. many evaporators have already used aluminum because the cost of aluminum is low. Copper is not oxygen-free copper.
