![A domestic refrigerator with inner
dimensions of 0.7 m by 0.7 m at the
base and height 1 m was designed to
maintain a set temperature of 6 °C.
The bodies consist of two 10-mm-
thick layers of Aluminium (k = 225
W/mK) separated by a 30 mm
polyurethane insulation
(k=0.028
W/mK). If the average convection
heat transfer coefficient at the inner
and outer surfaces are 11.6 W/m2K
and
W/m2K respectively,
14.5
