120 cm. The air outlet of the air duct machine is marked as 1.2 meters, 1 meter is 100 centimeters, and 1.2 meters is 120 centimeters in length. The air duct unit absorbs or releases heat from the air through the outdoor unit to realize cooling and heating functions. It transports hot and cold air to various indoor rooms through the air duct system to achieve an overall air conditioning effect.
One meter of air duct loses 5 Pa. Composite air ducts are represented by rubber-plastic composite air ducts. They are made from rubber-plastic composite insulating materials. They can completely replace air ducts, air valves, air vents, static pressure boxes and rubber insulation materials in air conditioning. air distribution systems. The static pressure loss rate of the co systemplastic composite air ducts is 5 Pa for one meter of air duct. Static pressure refers to the pressure exerted on the surface of an object when it is at rest or moving in a straight line at a uniform speed. The unit is Pa. Static pressure plus dynamic pressure equals total pressure.
