Equivalent length refers to the elbow and other parts of the tube with consideraon to the pressure lost aer
the conversion length.
The formula is as follows:
Equivalent length = actual length of pipe + number of elbows x Equivalent length of various elbows
The length of each branch is 0.5m, with the equivalent length of the elbow as follows:
Diameter
Equivalent length
Diameter
Equivalent length
Elbow(m) Elbow(m)
φ9.52 0.18 φ28.6 0.50
φ12.7 0.20 φ31.8 0.55
φ15.88 0.25 φ34.9 0.60
φ19.05 0.35 φ38.1 0.65
φ22.23 0.40
φ41.3 0.70
φ25.4 0.45
Note:
The equivalent length of elbow in the table above aims to fulll installaon standards: the pipe bending radius of curvature is R ≥ 3.5D (D for the pipe diameter),
about ≥ 3/4 of the original diameter before the pipe bending deformaon. If the elbow bending radius does not meet the above installaon standards, the
equivalent length is to be calculated separately (the smaller the bending radius, the longer the equivalent length).

1. Cooling condion: Indoor D/W bulb Temp. 27/19°C,outdoor temperature: D/W bulb Temp.35/24°C;
2. Heang condion: Indoor D/W bulb Temp. 20/15°C,outdoor temperature: D/W bulb Temp.7/6°C;
3. The noise level is tested in the incomplete anechoic lab under the standard refrigeraon condion and got from the average values from three points, 1 meter
in front of the unit, 1 meter from two sides of the unit and half of the unit height plus I meter. The real noise value in operaon may be a lile higher than the
tested value due to the inuence of the actual environment;
4. The width is just for the unit, not including the width of boom edge.
