Abstract:
The present invention relates to a system for remotely forecasting temperature, green tide, and red tide for each water level using a lidar and a method for remotely forecasting temperature, green tide, and red tide for each water level using a lidar. According to the present invention, by using a lidar to remotely monitor the concentration of chlorophyll a at a coastal water surface and the temperature of seawater (fresh water) at the same time, a more accurate forecast of red tide (greed tide) is possible. By understanding the influence of the concentration of chlorophyll a due to a change in the temperature, an annual trend of green tide and red tide generation can be determined and data on climate change and marine environment change can be obtained. Also, the present invention enables real-time broadband surveillance by which early warning on a frequent occurrence area of red tide and green tide is possible, thereby enabling efficient disaster prevention at an early stage and thus contributing to damage reduction. In addition, the present invention can apply various platforms such as personal carriage, embedding in a ship, and fixing at a coast, and ensure high sensitivity, night surveillance function, real-time monitoring, and broadband scanning investigation.

Abstract:
PURPOSE: A cold air flow structure of a refrigerator for the generation delay of frost is provided to use a control panel having inlets which are symmetrical to an outlet installed between the inside of the refrigerator and an evaporator. CONSTITUTION: A cold air flow structure of a refrigerator for the generation delay of frost comprises a control panel (40) and a discharge fan (50). The control panel has an outlet (41) and multiple inlets (42) and is installed on the front surface of an evaporator (30) to control the flow of air flowing between the inside of a refrigerator and a heat exchange space part. The discharge fan is installed in the outlet and discharges air from the heat exchange space part to the inside of the refrigerator. A part of the air flowing into the inside of the refrigerator is moved to a first heat exchange part formed between the control panel and the evaporator to cool the air, and the cooled air is discharged to the outlet. The residual air is moved to a second heat exchange part (22) formed between the rear surface of the evaporator and the inner surface of the refrigerator to cool the air, and the residual air is discharged to the outlet.
