I am pleased to be here today to discuss the increasing concern that our nations waters are becoming contaminated with methyl tertiary butyl ether (MTBE). About a third of the states, in certain areas, use gasoline that contains MTBE to help them limit air pollution because it burns cleaner. However, the substance could also pose risks to human health, especially as a contaminant in drinking wa...

Recently, the use of hybrid systems using multiple heat sources in buildings to ensure a stable energy supply and improve the system performance has gained attention. Among them, a heat pump system using both solar and ground heat was developed and various system configurations have been introduced. However, establishing a suitable design method for the solar-assisted ground heat pump (SAGHP) s...

Solar hot water tanks (SHWT) based on a latent heat storage system are gaining momentum for their integration into solar heater collectors. They can efficiently store daytime thermal energy and shift on-peak period loads to off-peak periods. However, performance is generally limited by the tank configuration, design of system, selection appropriate phase change material (PCM). This work present...
