DEVELOPMENT OF GENERAL-PURPOSE ENERGY SYSTEM ANALYSIS SOFTWARE-ENERGY FLOW ＋ M

摘要

To solve energy crisis and global environment problem, we must considerably improve the efficiency of systems for heating, refrigeration, air-conditioning. Simulation is an effective way to investigate these systems for the purpose of improving their efficiency. However, simulation technology cannot be efficiently transferred to others because description method of the simulation code developed varies depending on the programmers. Thus, we have developed a general-purpose energy system analysis software called 'Energy Flow ＋M' and have confirmed that this software can be applied to various energy systems. In this study, we considered a high-precision model of a CO_2 heat pump using this software and carried out steady state simulation. As a result of this study, it is possible for any user to simulate a CO_2 heat pump with Energy Flow ＋M and evaluated its performance by using the Internet.
