...Janna Martinek; Melinda Channel; Allan Lewandowski; Alan W. Weimer A methodology is presented for the design of solar thermal chemical processes. The solar receiver efficiency for the high temperature step, defined herein as the ratio of the enthalpy change resulting from the process occurring...

... the PCM from temperature measurements at one single point within the PCM. A powerful inversion technique has been proposed for that. Its most striking feature is that it allows identification of enthalpy-temperature functions in an easy way. They are retrieved by solving a problem of time-dependent source...

... and yielded 50 kg/h of 95%-purity Zn. The measured energy conversion efficiency, i.e., the ratio of the reaction enthalpy change to the solar power input, was 30%. Zinc finds application as a fuel for Zn/air batteries and fuel cells, and can also react with water to form high-purity hydrogen. In either case...

... the results obtained with the lumped capacitance method is referred as the enthalpy method ( 7 ). The enthalpy method is based on the conservation of energy expressed in terms of enthalpy and temperature. The energy conservation applied to a one-dimensional problem is expressed in the following: 12...

... and enthalpy, the interior zone airflow ratio, and the exterior zone supply air temperature. The optimal outside air control schedules can be applied to both constant and variable air volume systems. When the schedules are implemented, the OAHU system can significantly improve indoor air quality (IAQ) and use...
