{"title":"Giving Anergy a Value by the Application of an Anergy-exergy Cost Ratio in Thermo-economic Analysis of Systems that Make Thermal Energy Available","authors":"L. Meyer, I. Stadler","doi":"10.2991/ahe.k.220301.017","DOIUrl":"https://doi.org/10.2991/ahe.k.220301.017","url":null,"abstract":"Techno-economic analysis that allocate costs to the energy flows of energy systems are helpful to understand the formation of costs within processes and to increase the cost efficiency. For the economic evaluation, the usefulness or quality of the energy is of great importance. In exergy-based methods, this is considered by allocating costs to the exergy instead of energy. As exergy represents the ability of performing work, it is often named the useful part of energy. In contrast, the anergy, the part of energy, which cannot perform work, is often assumed to be not useful. However, heat flows as used e.g. in domestic heating are always a mixture of a relative small portion of exergy and a big portion of anergy. Although of lower quality, the anergy is obviously useful for these applications. The question is, whether it makes sense to differentiate between exergy and anergy and take both properties into account for the economic evaluation. To answer this question, a new methodical concept based on the definition of an anergy-exergy cost ratio is compared to the commonly applied approaches of considering either energy or exergy as the basis for economic evaluation. These three different approaches for the economic analysis of thermal energy systems are applied to an exemplary heating system with thermal storages. It is shown that the results of the technoeconomic analysis can be improved by giving anergy an economic value and that the proposed anergy-cost ratio allows a flexible adaptation of the evaluation depending on the economic constraints of a system.","PeriodicalId":177278,"journal":{"name":"Atlantis Highlights in Engineering","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128408246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inverter converts a constant AC voltage source into an AC voltage source whose frequency can be adjusted between 0-150 Hz.

Currently the production process used by the songket weaving craft is still very simple, most of the work process in making this woven fabric is done manually. This causes the production process to take a relatively long time compared to the manufacture of fabrics in general. The yarn spinning device is modified in such a way that the yarn spinner can work with the help of electronic components. The yarn spinner is given a DC motor which has previously been programmed using the L298N Motor Driver so that it can rotate as needed and is connected to the Node MCU ESP8266 module so that it can be connected to an Android Smartphone which is used as a remote control to run the yarn spinning device. The ESP8266 Node MCU functions as a command provider for each component, the Gearbox DC Motor functions as the main driver for the coils, the L298N Motor Driver functions as a DC Motor controller, and the MG966R Servo Motor functions as a thread guide to the left and right so that the results of the thread roll look neat.
