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 in the low℃ -pressure side(For the cooling type machine, no

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:

Pipe diameter (mm) Adiabatic material thickness

Refrigerant pipe

Φ6.4—Φ25.4 10mm

Φ28.6—Φ38.1 15mm

Drainage pipe

Inner diameterΦ20—Φ32 6mm

5.2 Refrigerant pipe insulation

5.2.1. Work Procedure

Before laying the pipes, the non① -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 ②

insulated

5.2.2. Insulation for non-jointing parts and non-connection parts

wrong right

Gas pipe and liquid pipe should

not be put together to insulate

Insulate the gas pipe

(cooling only)

Insulate the gas pipe and

liquid pipe
