You will notice that "PWM Floor Duty Cycle" is named as PPWM and " PPWM_margin*pwmMax " was added, this was to limit the maximum allowable PWM duty cycle since charge pump MOSFET driver like the IR2104 cannot operate at 100% duty cycle due to its IC design. It also turns the duty...
For the sake of simplicity, the average temperature between the inlet and outlet for each stream was used in the calculation. D. Energy Analysis Model The analysis is done via analytical equations and balances, explained in this section. The formulated equations were solved in EXCEL. Plant ...
Cost calculation using this method are on a US$ 2001 basis (CEPCI = 397) and is explicitly converted to AU$ 2019 basis. Design specifications for equipment found in the conventional PCC, the SA-PCC, and the SP-PCC technologies are listed in Table 2. For SA-PCC, a new process model ...
This design was intended to maximize sunlight collection, particularly during the morning and afternoon, thereby enhancing the thermal efficiency of solar collectors compared to fixed flat plate models. The developed solar dryer was utilized to dry salted tilapia fish fillets (STFF) at three slice ...
Microsoft Excel was used to perform statistical analysis of eleven mathematical models. The results show that the mixed-mode solar greenhouse dryer takes less time to dry red pepper than the open solar dryer. In the midday, the solar insolation reached 973 W/m2 and the minimum solar ...

Another solar urban design tool -GSOL (Goretzki, 2013) employs simple algorithms to compute heating demand of buildings in specific neighbourhoods. To estimate the heating load of the total neighbourhood, the tool repeats the calculation assuming that all buildings are unshaded. The tool allows al...
The calculation consists of three major models. The first model is a hydraulic optimization (HO) of the DHN calculating mass flows and, if not given, diameters for each pipe. This information is passed to the thermal design optimization (TDO). The TDO is a MILP model minimizing the annuity...
On the other hand, when no load is present, it is understood by way of calculation that a power of about 0.6 W is consumed in one overvoltage preventive element. That is, in the case where the operating voltage per one solar cell element unit of Comparative Example 1 is equal to the ...
