installing the unit _47ENGLISHINSULATING THE REFRIGERANT PIPEInsulating the refrigerant• You must check if there is a gas leak before completing all the installation process.• Use EPDM insulation which meets the following condition.Selecting the insulator of refrigerant pipe• Insulate the gas pipe and liquid pipe by referring to the thickness of insulator for each pipe size.• The standard condition is 30°C, less than humidity 85%. If the condition is in high humidity, useone grade thicker.Item Unit StandardDensity g/cm3 0.048~0.096Dimension change route by heat % -5 or lessWater absorption rate g/cm3 0.005 or lessThermal conductivity kcal/m·h·˚C 0.032 or lessMoisture transpiration factor ng/(m²·s·Pa) 15 or lessMoisture transpiration grade g/(m²·24h) 15 or lessFormaldehyde dispersion mg/L -Oxygen rate % 25 or lessPipe Pipe size (mm)Insulator(Cooling, Heating)RemarksStandard[30°C, 85%]High humidity[30 °C, 85% or more]EPDM, NBRLiquid pipe Ø6.35~Ø9.52 9t Heat resistingtemperature is morethan 120°CØ12.70~Ø50.80 13t Gas pipeØ6.35 13t 19tØ9.5219t25tØ12.70Ø15.88Ø19.05Ø22.23Ø25.40Ø28.5832tØ31.75Ø38.10Ø44.45Ø50.80 25t 38t
