Abstract
In the Refrigerating Industry, the frosting of
refrigerating coils and its effect on heat transfer is a
problem of obvious importance. Amount of frost on the
evaporator is dependent on the ambient temperature and
air humidity. The performance of any cold storage unit
depends upon maintaining storage space and evaporator
temperatures within a range of most favourable conditions.
This research project therefore is aimed at investigating
the peculiarities of frosting, especially the
variations of the heat transfer coefficient as a function
of the duration of use during frosting with the influence
of air conditions as close as possible to those in practice
and to present some recommendations for defrosting on the
basis of the results obtained.
The theory of frost formation is outlined and its
complexity identified.
Design procedure of a cold storage is briefly given.
This is to give readers an idea of how the various components
of the system, eg, the evaporator, the condenser,
etc were selected; the various factors that contributed
to the successful working of the unit.
Measurements on a house hold refrigerator are present
tedj the results obtained are analysed and on the basis
of these results and the experience obtained during the
performed tests, some conclusions and recommendations are
made.
