6. Refrigerant Flow Diagram
Thermal insulating of refrigerant pipeline
To prevent heat loss and condensed water from dropping on the floor, the wide and narrow tube of
air conditioner should be wrapped with thermal insulating materials. For using capillary tube, and the
tubes are in low temperature, the thickness of thermal insulating materials shall be more than 8 mm.
Narrow tube
Ф
6.35 mm(1/4”)
Ф
9.52 mm(3/8”)
Wide tube
Ф
12.7 mm(1/2”)
