requirements at the low-pressure side.)
Example: Heat pump type----Heat-resistant Polyethylene foam (withstand above 120 )
Cooling only type---- Polyethylene foam (withstand above 100 )
5.1.2. Thickness choice for insulation material
Insulation material thickness is as follows:
Refrigerant pipe
Drainage pipe
5.2 Refrigerant pipe insulation
5.2.1. Work Procedure
Before laying the pipes, the non-jointing parts and non-connection parts should be heat insulated.
When the gas proof test is eligible, the jointing area, expanding area and the flange area should be heat
insulated
