In the actual installation process, due to factors such as air duct material, fan coil accessories (such as filters), and outlet grille style, there is an error of approximately 1-1.5 meters in the distance that fan coil units can blow.
How many meters can a fan coil unit blow at static pressures of 12Pa, 30Pa, and 50Pa? How many meters of air duct can be connected? The static pressure of fan coil units refers to the ability of indoor air conditioning units to overcome pipeline resistance, directly affecting the maximum air supply distance of the unit, expressed in terms of pressure. The unit is Pa.
Generally, ordinary iron sheet air ducts (coated with insulation cotton) have a static pressure loss of 5Pa based on a length of 1 meter, and the static pressure loss of the air outlet grille is calculated based on 5-10Pa.
A 12Pa static pressure fan coil unit can blow up to 1-1.8 meters away. Therefore, it is not recommended to connect air ducts to a 12Pa static pressure fan.
A 30Pa static pressure fan coil unit can blow up to 4-5 meters away.
A 50Pa static pressure fan coil unit can blow up to 8-9 meters away.
The above data is a relatively ideal state.
In the actual installation process, due to factors such as the material of the dry air duct, fan coil accessories (such as filters), and the style of the air outlet grille, there is an error of approximately 1-1.5 meters in the distance that the fan coil can blow.
