2. Selection of Pipe and Heat Insulation Materials
• When using commercial copper pipes and fi ttings, observe the following:
1) Insulation material: Polyethylene foam
Heat transfer rate: 0.041 to 0.052 W/mk (0.035 to 0.045kal/mh°C)
Refrigerant gas pipe's surface temperature reaches 110°C max.
Choose heat insulation materials that will withstand this temperature.
2) Be sure to insulate both the gas and liquid piping and to provide insulation
dimension as below.
Pipe Dimension Heat Insulation Dimension
Gas side 3/8"(O.D. 9.5mm t0.8mm) I.D.12-15mm t10mm Min
Liquid side 1/4"(O.D. 6.4mm t0.8mm) I.D. 8-10mm t10mm Min
3) Use separate heat insulation pipes for gas and liquid refrigerant pipes.
