This work focuses on the determination of design and operation parameters a thermal system depending optimization objective set. Its main contribution concern proposal generalized methodological structure involving multiobjective techniques aimed at providing solution to practical problem, such as dimensioning solar system. The analysis is based data provided by dynamic simulation model, leadin...

Background Scalds from domestic hot water are an important public health problem in New Zealand (NZ). Aims We aimed to study the hot water hazard in a yet unstudied setting: that of campgrounds. Methods Convenience sampling was performed involving 25 NZ campgrounds. These were sampled during summer months over a 4-year period (2008–2011) and in five different regions. We measured the temperatur...

By dynamically measuring solar storage&& temperature(s), the solar storage tank effectively becomes a dynamic calorimeter to measure the energy flows in a solar system. The energy flows include solar loop gain, tank losses, and potentially draw extraction. With one-channel temperature loggers storing data over several days to several weeks, this approach provides low-cost, modest-accuracy perfo...

Buildings consume approximately 4 of the total electricity generated in the United States, contributing significantly to fossil fuel emissions. Sustainable and renewable energy production can reduce fossil fuel use, but necessitates storage for energy reliability in order to compensate for the intermittency of renewable energy generation. Energy storage is critical for success in developing a s...
