The manual calibration was time-consuming, fatiguing, and difficult to collect data. To improve this measurement process, SNSU-BSN has developed an automatic calibration system for solid-state DC voltage standards using programmable software for data acquisition and a low thermal scanner for switching during the measurement. A differential measurement method is performed for automatic calibration system in 1.018 V and 10 V. This automatic calibration system has been validated with manual calibration mode for measurement repeatability in same environmental condition. The result shows that the standard uncertainties of repeatability for automatic and manual calibration at a nominal voltage of 1.018 V are 0.0035 μV and 0.0071 μV, and for a nominal voltage of 10 V are 0.090 μV and 0.038 μV, respectively. The normalized error (En number) values of nominal voltage 1.018 V and 10 V are less than 1, stating that the results of automatic and manual measurements are in good agreement. Therefore, the automatic measurement system can be applied to replace the manual process of measurement at SNSU-BSN since this method is faster and has better uncertainty values.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135691591","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}

Developing a single-pass absorber of the solar air heater in the form of a wire mesh layer will significantly improve its performance under certain climatic conditions. To further increase the efficiency of the modified solar heater so that it can adapt to all climatic conditions, an automatic control system combined with a fan motor has been designed and integrated with the heater to provide it with suitable parameters such as temperature and airflow rate. To determine the effect of the automatic fan speed control affects solar air heater performance, an experimental investigation is presented in this paper. Under identical weather conditions, two tests were conducted for two consecutive days, one without and one with using automated fan speed control. The control system was programmed to regulate outlet air temperature with a range of 40-60 °C. Accordingly, the fan speed is automatically changed in response to temperature variations. Online monitoring and adjustment of temperature will increase air temperature stability and stop oscillations despite varying solar radiation levels during daytime hours. With greater thermal efficiency than conventional technique, this technology encourages more even airflow and improved heat transfer, raising surface temperatures in the heater duct. By using automated control, the thermal efficiency of the heater is increased by roughly 39.5 %.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135690516","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}
