This paper demonstrates the preliminary experiments for two stage water desalination by humidification-dehumidification HDH process. An experimental set-up consists of two stages of closed air humidification dehumidification units. In this design, the saline water was heated by evacuated tube solar water heater integrated with electrically heated tank. A series of tests were performed in outdoo...

<em>Solar water heater is a device that uses solar collectors to absorb radiation and convert it into heat energy water. The type of collector the flow rate used affect thermal efficiency heater. This research with serpentine configuration copper pipe material applies 1 lpm. purpose this determine effect on produced by configuration. quantitative research, experimental methods. was conduc...

This paper investigates how to develop a learning-based demand response approach for electric water heater in a smart home that can minimize the energy cost of the water heater while meeting the comfort requirements of energy consumers. First, a learning-based, data-driven model of an electric water heater is developed by using a nonlinear autoregressive network with external input (NARX) using...

This summer I had my first experience with something every homeowner dreads (and knows is coming eventually): a sudden puddle of water underneath the hot water heater. A local plumbing company quickly sent a technician out, who spared no time in pronouncing our current hot water heater dead. Then he explained that this company used flat-rate pricing: all jobs of a certain type cost the same fix...

Solar energy is a good option among renewable energy resources due to its easy availability and abundance. The simplest and most efficient way to utilize solar energy is to convert it into thermal energy and this can be done with the help of solar collectors. The thermal performance of such collectors is poor due to less heat transfer from the collector surface to air. In this work, experimenta...
