The primary function of thermal insulation materials used as insulation liner is ice to reduce the transmission of heat through fish hold walls, hatches, pipes or stanchions into the place where chilled fish or ice is being stored. By reducing the amount of heat leak, the amount of ice that melts can be reduced and so the efficiency of the icing process can be increased. As has already been discussed, ice is used up because it removes heat energy from the fish but also from heat energy leaking through the walls of the storage container. insulation liner in the walls of the container can reduce the amount of heat that enters the container and so reduce the amount of ice needed to keep the contents chilled.
The main advantages of insulation liner are:
- Insulation liner help to prevent heat transmission entering from the surrounding warm air, the engine room and heat leaks (fish hold walls, hatches, pipes and stanchions);
- Insulation liner help to optimize the useful capacity of the fish hold and fish-chilling operating costs;
- Insulation liner help reduce energy requirements for refrigeration systems if these are used.
