KFR-32GW/DY-ID(D3) is a silent series product with strong refrigeration and heating power. Choose an efficient compressor, so that the core components of the air conditioner can keep up with the stable quality of the international level and ensure the high efficiency, energy saving and long life of the air conditioner. The contact area between the third generation trapezoidal internal thread copper tube and the refrigerant is larger than that of the ordinary copper tube. The trapezoidal internal thread copper tube makes the refrigerant violently disturbed in the pipeline, which makes the refrigerant fully exchange heat with the copper tube, greatly improving the heat exchange efficiency of the air conditioner.
