There are many fish farms being cultivated in the southwestern cost of South Korea. Because the farms cultivating use the basic method that inflow and circulate sea-water, slight negligence and bad design cause major negative impact on fish deaths. Also, the optimal temperature for each specie of fishes has already been proven to differ on each specie. Maintaining this environment, regardless of seasons, is very difficult and that requires research to develop. In this paper, basic characteristics of heat and mechanism of heat transfer are studied. Based on this, Open-end water vessel is designed and constructed using sandwich-insulation panels and simulated to store the heat in certain isolated space. This study confirmed that it is possible to keep constant temperature by this method, in large areas of water where it is insulated by heat insulator. and equipped with heater in Open-end water vessel where the other part is heated. The AC power controller maintains the constant temperature required and the temperature controller detects and displays the temperature by using the micro-processor.
