5. Insulation Work

5.1 Insulation material and thickness
5.1.1. Insulation material
Insulation material should adopt the material which is able to endure the pipe's temperature: no less than
℃
70 in the high -pressure side, no less than 120
requirements at the low-pressure side.)
u 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
