GMV6 DC Inverter VRF Units Technical Sales Guide
NOTES:
a.*Normally, the pipe length from the first branch of IDU to the farthest IDU is 40m. When those three
conditions as below are satisfied, the length can reached 120m.
①
Actual length of pipe in total: L1+L2x2+L3x2+L4x2+…+L9x2+a+b+…+i+j≤1000m.
②
Length between each IDU and its nearest branch a, b, c, d, e, f, g, h, i, j≤40m.
③
Difference between the pipe length from the first branch of IDU to the farthest IDU and the pipe
length from the first branch of IDU to the nearest IDU: L10-L11≤40m.
b.**When the ODU is at the up side and the height drop exceeds 50m, please contact the engineer;
when the ODU is at the lower side and the height drop exceeds 90m, please contact the engineer.
When the ODU is at the up side and the height drop between the IDU and ODU is more than 50m, the
liquid pipe size from the ODU to the first manifold of IDU must be enlarged.
When the ODU is at the lower side and the height drop between the IDU and ODU is more than 40m,
the liquid pipe size from the ODU to the first manifold of IDU must be enlarge
c. When the height drop among IDUs is more than 15m, the liquid pipe size from the ODU to the first
manifold of IDU must be increased.
d.When the maximum length of the main pipe from ODU to the first branch of IDU is≥90m, then adjust
the pipe size of the gas pipe and liquid pipe of main pipe according to the following table.
