(3) Refrigerant Piping
Maximum Piping Length and Maximum Number of Bends
When the pipe length becomes too long, both the capacity and reliability drop. As the number of bends
increases, system piping resistance to the refrigerant
fl
ow increases, thus lowering the cooling capacity,
and as the result the compressor may become defective. Always choose the shortest path and follow the
recommendation as tabulated below:
