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...

The encapsulation technique is one way to use latent heat storage material in a solar water heater tank. In this technique, several capsules may be arranged the study, were installed along cross-section of There has been no discussion which part capsule position optimal energy with arrangement. Proper placement arrangement can result thermal This study aimed investigate effectiveness installing...

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...

introduction electrical performance of solar cells decreases with increasing cell temperature, basically because of growth of the internal charge carrier recombination rates, caused by increased carrier concentrations. hybrid photovoltaic/thermal (pvt) systems produce electrical and thermal energy simultaneously. pvt solar collectors convert the heat generated in the solar cells to low temperat...

Problem statement: The process control of steam boiler is very popular used in the industrial. The temperature of the water is transferred directly by electrical heater. The pressure will increase based on the changing of the temperature. The purpose of the control is to change the opening set point for the valve when the temperature and pressure in the tank are changed. For this problem, we de...

––Based on technology and economy, a design of explosion-proof heater of bunched pipeline is mentioned in this paper to solute the problems of the present heater which is used to heat crude oil in winter. The structure and working principle of this new heater are introduced. And the function of the new heater’s swirl plate is described, before the heater power of the new heater is analyzed. The...

The performance of an air-source heat pump water-heater (ASHPWH) system manufactured by Kronoterm was benchmarked in this study for the application dairy farming Ireland. COP calculated to be 2.27 under normal operating conditions. device able supply water at 80 °C, however a full tank temperature not achieved or deemed necessary application. Litres per kWh used as metric and usable unit energy...

In this paper thermo-hydrodynamic characteristics were investigated experimentally for a new type shell-helical coiled tube heat exchanger used as storage tank of closed loop solar water heater system. Triple concentric helical coils made copper tubes (12.5mm OD and 10mm ID) with diameter (207, 152.2, 97mm) outer, middle inner respectively. The experiments carried out during clear sky days (Mar...

Solar water heating system technology is described and the scale of the International solar water heater market is surveyed. New product developments for both direct solar water heating and solar boosted heat pump water heating are outlined. Procedures adopted by the International Standards Organisation for assessing solar water heater performance and quality are discussed.
