概要:

Deep-sea observations have been conducted for the earthquake prediction through the acquisition of crustal deformation data and the influence of marine environment. Energy supply system for deep-sea observation tools is a necessity in long-term deep sea observation. There are high potential energy reservoirs and many active hydrothermal vents. Thermal energy conversion system using submarine hydrothermal utilizes two heat sources with different temperatures between submarine hydrothermal and cold deep seawater. The effective temperature difference of the working fluid is less than the heat source temperature difference due to the heat exchange between the working fluid and the heat source. This paper investigates on the influence of the heat source temperature change in the heat exchange process and the thermal characteristics of the working fluid on the system performance of the power generation system using submarine hydrothermal. The parametric performance analysis of Rankine cycle is carried out using the thermal characteristics of three working fluids. As a result, the maximum power output of water is the largest in three working fluids, followed in order by toluene and pentane. The low-temperature heat source, which is cold deep seawater, has strong influence on the maximum power output.

An abstract:

Deep-sea observations have been conducted for the earthquake prediction through the acquisition of crustal deformation data and the influence of marine environment. Energy supply system for deep-sea observation tools is a necessity in long-term deep sea observation. There are high potential energy reservoirs and many active hydrothermal vents. Thermal energy conversion system using submarine hydrothermal utilizes two heat sources with different temperatures between submarine hydrothermal and cold deep seawater. The effective temperature difference of the working fluid is less than the heat source temperature difference due to the heat exchange between the working fluid and the heat source. This paper investigates on the influence of the heat source temperature change in the heat exchange process and the thermal characteristics of the working fluid on the system performance of the power generation system using submarine hydrothermal. The parametric performance analysis of Rankine cycle is carried out using the thermal characteristics of three working fluids.
