OPTIMISATION OF INSULATION AND REFRIGERATION PLANTS ON SHIPS

Of the range of foodstuffs carried in refrigerated ships, fruit imposes the most exacting requirements, particularly stoned fruit and bananas; however, an installation designed for fruit can, with little technical difficulty, be adapted for the full range of refrigerated cargoes. Based on the biological requirements for fruit, the design features of a marine refrigeration plant necessary to ensure the economically-optimum storage life of the cargo in transit are discussed in considerable detail. For conventional break-bulk reefer ships, it is concluded that present designs of refrigeration systems, comprising insulated chambers through which air cooled by air-refrigerant heat exchangers is circulated by fans, are adequate for all requirements. The best installation is thought by most users to be one comprising screw compressors using R22 as primary refrigerant and circulating brine as a secondary refrigerant to the coolers and cargo spaces. Various refrigeration systems are now in use in containerships, but there is a present insufficient service experience to enable any one to be selected as the best for all trades.
