英语翻译
Forty cylinders made of plaster (5 cm diameter,49 cm
length) were immersed in water overnight,16 of them were
equipped with 2 thermocouples (at the surface and in the
centre).To ensure the steady state in the model refrigerator to
the greatest extent possible,the initial cylinder temperature
should be as close to the air temperature as possible.To reach
this condition,the cylinders were wrapped in aluminium foil
after soaking and placed in a domestic refrigerator (mean air
temperature 5 3
C) for several days.Thenthe aluminiumfoilwas
removed and the cylinders were arranged on supports in the
model refrigerator.After cylinder loading,the model refriger-
ator was closed rapidly.The temperature of the instrumented
cylinders was recorded by a data logger and then the mean
value was calculated when steady state was attained.The
weight of the cylinders wasmeasured after 1,2,3,4,7,9 and 11
days.The cylinders were removed from the model refrigerator
and placed on a balance located in the test room before being
rearranged in the cavity.The 40 cylinders were weighed in less
than 30min so that any disturbances in product weight due to
changes inambient conditions duringweighingwere negligible.
