||This project will study the insulation characteristics and fan location of the refrigeration room for saving the energy of far-sea fishing boats and analyze the effect of its energy-saving. Expecting the medicament mixing ratio in blowing agent is developed to enhance much better insulation performance. In many research points at the design of fan blades, this time we will aim at the fan’s positions and amounts for the refrigerator room. We are expecting that to improve the frozen effect to energy-saving on the fan’s positions and amounts. If improving the problems of the frozen effect to energy-saving in far-sea fishing boats, it could reduce the energy in the refrigeration room. It not only could improve the fish’s fresh but also could reduce the power consumption and human resources. It could achieve the best economic benefits on SOP.
