b)material
Insulation material used should be able to endure the heat pipe.
for example:heat pump;Heat-resistant polyethylene foam(
120
).cooling only:Polyethylene foam (
100
)
c)heat preversation work points:
d)important point
the thickness of heat insulation material should be determined by pipe diameter
pipe diameter
6.35mm~22.2mm
28.6mm~38.1mm
thickness of heat insulation material
l0mm or more
15mm or more
on the occasion of hot and wet environment the recommended values in table should be increased
L
e akage test
a)operation procedure
refrigerant pipe finifshed
add pressure
check if pressure decrease
eligible
check leakage point and restore
no
yes
support of heat prevention
copper pipe
heat insulation
metal frame
arc-shaped gasket
both gas and liquid pipe
are heat insulated.
true
false
gas and liquid pipe
should not insulation
together
the connection part of
refrigerant pipe should be
heat insulated completely.
only gas pipe(cooling only)
connection part
doesn't be
heat insulated
