COLD STORE AND LOADING DOCK DESIGN TO MINIMIZE CONDENSATION AND COIL FROSTING PROBLEMS
Two frequent problems for refrigerated storage facilities are condensation/icing in loading docks and very rapid decline of cooling coil performance due to formation of “unfavourable frost if the air becomes super-saturated as it is cooled. Models of the main moisture transport processes that enable air RH and the potential for condensation/icing and unfavourable frosting to be predicted are summarised. Use of the models for a typical facility with a cold store and loading dock showed that condensation and unfavourable frost formation are likely even if ambient conditions are not that extreme and moisture entry is reduced by doorway protection. Condensation/icing and unfavourable frosting can be best avoided by a combination of improved coil design (e.g. appropriate TD) and enhanced door protection (especially doors opening to the ambient) but occasionally active dehumidification or special coil designs (e.g. staggered fin spacing) must be used.
