In buildings, materials used to control the outflow of indoor heat are traditionally called thermal insulation materials, and materials that prevent outdoor heat from entering the room are called thermal insulation materials.

Thermal insulation cotton is a non-toxic, harmless and non-polluting new thermal insulation material made of high-purity clay clinker, alumina powder, silica powder, chromite sand and other raw materials.

The weight of phenolic composite air duct is light, about 1.4 kg/m2, while the bulk density of galvanized steel duct (0.8mm thick) and glass fiber reinforced plastic duct (3 mm thick) are 7.08 kg/m2 and 15~20 kg/m2

The Ventilation System (fresh air system) is an independent air treatment system composed of a supply air system and an exhaust air system. It is divided into two types: a ducting fresh air system and a ductless fresh air system.

The unidirectional flow system is a diversified ventilation system formed by the combination of central mechanical exhaust and natural air intake based on the three principles of mechanical ventilation system.

Summer is the peak season for air-conditioning. However, some careful users will find that there are some small water droplets on the air-conditioning outlet panel, thinking that the air conditioner indoor unit is leaking. In fact, these small water droplets are air-conditioning condensate water.

Everyone knows that air-conditioning shutters are used in fresh air systems and central air-conditioning systems. According to the material, the air outlets are divided into aluminum alloy air outlets,
