Frost - on air-cooling evaporators (Reindl & Jekel 2009)
by Reindl & Jekel
This paper discusses the operation of air-cooling evaporators in industrial refrigeration applications at temperatures below freezing. These heat exchangers are generally applied to control the environmental conditions in holding freezers, dynamic blast freezers, stationary blast cells, refrigerated docks, as well as other lower temperature conditioned spaces found in food manufacturing and distribution facilities. Factors that influence the formation of frost on the evaporator surfaces are reviewed and details on how frost accumulation impacts coil performance discussed.
