Connection pipe should adopt water-proof insulating material. Its wall thickness
should be 0.5-1.0mm and the pipe wall should be able to withstand 6.0MPa. The
longer the connection pipe is the worse cooling and heating performance it has.
When the drop between indoor and outdoor units is larger than 10m, an oil
return bend should be added every 6 m.
