2. Preparation for installation

Problem analysis

 Selecting ø22.23 copper pipe, and 10mm insulation as

shown in the picture.

Consequence



Low insulation effect cause large energy consumption

and decrease in system performance.



Condensation will easily form and leakage may occur

when performing heating operation in regions with high

temperature and humidity.

Standard procedure

 Insulation material and quality must meet the minimum

standard thickness requirements.

 Good installation will prevent condensation and

guarantee air conditioning performance.

Proper method

 Follow the below specification strictly and aware of the

Minimum thickness requirements.

Pipe size

[mm]

Minimum thickness of insulation [mm]

PE foam

EPDM foam

Ø6.35~19.05

Ø22.23~31.75

Ø38.10

Ø44.45~

 The thickness of insulation must be increased in case of

high humid conditions (over than 27°C and RH 80%)

like below place

- Tropical / Subtropical regions or equivalent with this

region

- The region where problems due to high temperature

and humidity are expected

- Restaurant, hot spring, sauna, basement, seaside

Ceiling inside with high humidity due to weak

ventilation
