Demand-side energy management systems (EMSs) are expected to be used as a method for further balancing the supply and demand of power systems with high levels of renewable energy generation, such as photovoltaic (PV) power. Energy demand and solar radiation must be predicted to realize the optimal operation scheduling of demand-side appliances by a home energy management system (HEMS), includin...

IR Versus Convection Heating Medium-wavelength electric IR heating is especially wellsuited to the curing and drying of coatings, because these wavelengths correspond well with the absorption bands for water, which most coatings contain. Additionally, since IR heating does not penetrate the surface very deeply and generally only heats the outer surface, it is applicable for drying coated and pr...

Effects of insertion of coiled wire in juxtaposition with twisted tapes on heat transfer rate and solar radiation without disturbing the flow inside the riser tubes in a solar flat plate collector is experimentally reconnoitered in this present work. The wire coil used as a turbulator is placed inside the riser tube while the twisted tape is inserted into the wire coil to create a continuous sw...

short of incineration or boiling will be effective. Furthermore, these results suggest that temperatures achievable in point-of-use hot water heaters (household units) can deactivate infectious B. procyonis eggs, thus providing an option for maintaining safe drinking water during a possible event of bioterrorism or a “boil water advisory.” However, further efforts are needed to determine the ef...

Urine osmolality was studied in 38 babies nursed in conventional incubators or cots and 18 nursed under an overhead radiant heat shield. Among 50 babies receiving a similar fluid intake in the first 48 hours of life mean urinary osmolality was significantly higher in the radiant heater group. In babies weighing less than 1500 g a trend towards higher urinary osmolalities was recorded in those n...

Five years after a 1983 Washington State law required new water heaters to be preset at 49 degrees C (120 degrees F), 77% of homes (84% of homes with postlaw and 70% of homes with prelaw water heaters) had tap water temperatures of less than 54 degrees C. In 1977, 80% of homes had tap water temperatures greater than 54 degrees C. Mean temperature in 1988 was 50 degrees C compared with 61 degree...
