英文要約Subject: “Renewable Energy Heat Utilization Technology Development / High-Efficiency and Standardization of the Total System for Renewable Energy Heat Utilization / Research and Development of the Optimization Methods for a Solar Collection System” The interim report of FY 2016 for the period from FY 2015 to FY 2018

This research and development aims to reduce cost of the total system by optimizing the program for assessing energy saving performance used in the solar heat utilization field so that renewable energy heat can be utilized more effectively. This project also seeks to establish more detailed evaluation methods that enable selection of appropriate equipment through the development of optimization methods (simulation technologies). The following research and development were conducted in FY 2016.
(1) Optimization of the program to assess energy saving performance
Energy saving performance of solar heat equipment is evaluated as relatively low with the Program to Assess Energy Saving Performance. Accordingly, a large-scale equipment is required to obtain needed energy saving performance, leading to increase of the cost to introduce equipment. The projects are intended to establish the technology to evaluate performance that enables the introduction of equipment of an appropriate scale and to develop a simplified simulation tool to be reflected on the assessment program.
Established the verification test equipment to obtain the operation data of the solar heat system that are needed for the development of a simplified simulation tool, and started obtaining necessary data. Conventional tools have problems such as the one that the heat collection performance, one of its parameters, can only be evaluated with fixed values. In the simplified simulation tool, the parameters to be modified were examined so that the performance values close to the actual performance of equipment could be used for evaluation.
(2) Development of optimization methods (simulation technologies)
This research and development has a goal to succeed in the optimization of a heat collection system that is much closer to reality with greater accuracy by establishing optimization methods (simulation technologies) reflecting the results of verification and evaluation. There is also another goal, that is, to establish design tools using the optimization methods developed in this way, which would help many users including those considering the introduction of equipment as well as designers.
We examined given conditions (inputted matters) for simulation in preparation for the development of specific simulation technologies. In addition, we designed the basic structure of the modules of simulation software used for a solar-powered water heater. Verified accuracy using the data obtained in the verification test, and considered the plan to improve accuracy.
The actual measured values match calculated values to the extent that a simulation with high accuracy has been successfully developed.
