[0002] At present, after the HVAC pipes have been used for a certain period of time, a lot of scale may accumulate on the inner wall of the HVAC pipes. The thermal conductivity of scale is very poor, which will cause the heat transfer of the heated surface to deteriorate. Due to thermal expansion and contraction and uneven force, the risk of HVAC pipe rupture or even explosion is greatly increased. When the scale is cemented, a large amount of heavy metal ions are often attached. If it is used to transport water, there is a risk of excessive dissolution of heavy metal ions in water. Therefore, the harm of scale is obvious, so it is very necessary to clean the scale. However, in the current cleaning of scale, most places still do manual cleaning. Manual cleaning of scale is not only time-consuming and labor-intensive, but also inefficient, and the cleaning is incomplete, with a lot of scale residue, and the potential harm is still great.
