Refrigerant Piping Work

2-2. Selection of Copper and Heat Insulation materials

• When using commercial copper pipes and fittings, observe the 

following:

1) Insulation material:  Polyethylene foam

Heat transfer rate:  0.041 to 0.052W/mK (0.035 to 0.045kcal/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 dimensions as below.

3) Use separate thermal insulation pipes for gas and liquid refrigerant pipes.
