Study on low pressure evaporation of fresh water generation system model

This chapter undertakes a comprehensive survey and analysis of kabuki, aiming to explore a narrative generation-reception and a narrative production-consumption model of kabuki from the viewpoint of an information system and, in particular, a narrative generation system. A fundamental concept of the modeling is “multiplicity,” or multiple narrative structures. In addition, the author associates this model with the concept of the Geinō Information System (GIS), representing a system model in which multiple narrative generations and production mechanisms or processes are included. This chapter presents introductory knowledge on kabuki, including history and basic terms, as background for the discussion. In addition, this chapter shows the results of concrete analyses of kabuki's elements, including “person,” “story,” “tsukushi,” and “naimaze.”

Power Generation System

Temperature is one of the important factors affecting the power generation efficiency of PV cells. In order to improve the efficiency of photovoltaic power generation systems and heat utilization efficiency, we used Matlab/Simulink to build photovoltaic power system analysis model based on thermal power. By changing the heat and illumination input to the photovoltaic cell model and the heat generated by the battery we got the characteristics and temperature characteristics of the photovoltaic cell the system model, the photovoltaic power generation system model and the output power correction, etc. We got the environmental temperature change equation through the actual air temperature and curve fitting and used real and detailed data to compare the data obtained using the equation for online correction. PV cells temperature factor was used to get the PV cells temperature with the environment temperature changes. In order to get PV module thermal /energy efficiency the dates was processed and analyzed by using Matlab and Excel through actual observation data of school 120KW PV power station. The results showed that power generation efficiency increased and year average efficiency PV improved 21.3279% through the use of some heat about PV cells.

A new desalination system has been proposed and designed for converting sea water into fresh water utilizing the waste heat of internal combustion engines. The desalination process is based on the evaporation of sea water under a very low pressure (vacuum). The low pressure is achieved by using the suction side of a compressor rather than a commonly used vacuum pump. The evaporated water is then condensed to obtain fresh water. The effects of operational variables such as evaporator temperature, condenser temperature, vacuum pressure, and flow rate of both evaporator and condenser on the yield of fresh water are experimentally investigated. It is found that decreasing the vacuum pressure causes a significant increase in the yield of fresh water. It is also found that decreasing the condenser temperature, or increasing the evaporator temperature both lead to an increase in the yield of fresh water. Moreover, increasing the condenser flow rate tends to increase the yield of fresh water. The same trend is attained by increasing the evaporator flow rate.
