Apart from temperature there are few differences between carrying cargoes of chilled meat, minus 1 degree Celsius, and frozen meat, minus 18 degrees Celsius. A key difference is that for frozen meat the cooling fans are operated at half speed or some are switched off whereas for chilled meat the fans are run constantly at full speed. Select, from the options given, the main reason for this difference in fan operation.
It is an energy saving measure since chilled meat cargoes do not require as much cold air.
The chilled meat is more sensitive to damage and therefore tighter temperature control is necessary.
The fans may be damaged if they were run at full speed delivering very cold air to the frozen cargo.
Running the fans at full speed would generate too much heat which may affect the frozen meat.
