Performing leak test & insulation
5. Select the insulation of the refrigerant pipe.
• Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size.
• Indoor temperature of 86 °F(30 °C) and humidity of 85% is the standard condition. If install in a high humidity
condition,use one grade thicker insulator by referring to the table below. If installing in an unfavorable conditions,
use a thicker wall insulation.
• Insulator's heat-resistance temperature should be more than 248 °F (120 °C).
Pipe
6.35~9.52
Liquid pipe
12.7~50.8
9.52~25.4
Gas pipe
28.58~44.45
• When installing insulation in places and conditions below, use the same insulation that is used for high humidity
conditions.
<Geological condition>
‐ High humidity places such as shoreline, hot spring, near lake or river, and ridge (when the part of the building is
covered by earth and sand.)
<Operation purpose condition>
‐ Restaurant ceiling, sauna, swimming pool etc.
<Building construction condition>
‐ The ceiling frequently exposed to moisture and cooling is not covered.
e.g. The pipe installed at a corridor of a dormitory and studio or near an exit that opens and closes frequently.
‐ The place where the pipe is installed is highly humid due to the lack of ventilation system.
