They refer to pipe systems designed and installed specifically for the transmission and distribution of heating, chilled water, hot water, refrigerants or other fluids required by HVAC systems (such as air, water, and refrigerants). These pipes are used to connect and transmit various HVAC equipment such as heating, chillers, water heaters, cooling towers, fan coils, and air conditioning terminal equipment to ensure that the indoor environment reaches the appropriate temperature, humidity, and air quality.

[0003] During the use of HVAC pipes, scale will inevitably accumulate on the inner wall. As the scale accumulates, the cross-sectional area of ​​the pipes gradually decreases. In severe cases, it will cause partial or complete blockage inside the pipes, affecting the normal flow of water and causing serious impact on the operation of the entire HVAC system. Therefore, it is necessary to use a HVAC pipe scale cleaning device.

The inner diameters of HVAC pipes of different specifications vary, and a brush head with a fixed diameter cannot be suitable for pipes of all sizes. In particular, for pipes with large diameter variations or non-standard sizes, a single-sized brush head is difficult to perform comprehensive and effective cleaning. Utility Model Content
