Heat pump 50Hz/R410A
Part 3 Design and installation
3) Insulation tube thickness
①
Thickness decision of insulation tube
• Insulation material: EPDM or polyethylene foam
• Thermal conductivity 0.035 kcal~0.040kcal/mh°C
• Heat resistance=100°C(Cooling only) or more
120°C(Heat pump) or over
②
The thickness of the thermal insulation material must be determined in the light of the pipe sizes.
③
It will be necessary to increase the thickness of insulation in the above table when conditions are hot and humid.
④
Where a customer supplies his own specifications then these must be adhered to.
Pipe size
Thickness of insulation material
(normal)
6.35 ~ 25.4 mm
10mm or more
25.4 ~
15mm
Outdoor temperature and hummidity around the cooling piping might exceed 30°C and RH80%, reinforce the insulation on
the cooling piping (at least 20mm thick)
