Abstract
This study shows a new approach to heat water in a residential environment. An electromagnetic heating method is proposed. A steel bar inside a pipeline filled with water is heated by five arrangements of a copper coil which incites the steel bar by electromagnetic induction. Consequently, numerical simulation and experimental evaluation are compared. The outcomes evaluated two different scenarios: steady water and a water flow of 0.16 kg/s. Three rods demonstrated that current induction of 20 A at the surface of the steel bar heats at 157°C. Also, the maximum value reached is 58°C. Heating the water upon for those conditions, the proposed tankless instantaneous water heater (TIWH) reaches a temperature of 41.01°C with one rod but only reaches 37.92°C with three rods in a series configuration, in a parallel configuration, the maximum temperature reached was 28.73°C.
Highlights
A water heating system is defined as a device that transfers energy by heating water, regulating the water flow process, and operation temperature, among others.[1]
Compared to Canada, reducing the use of fossil fuels by 59% followed by a 35% electricity use, showing a tendency to adopt green energies in the last years.[3]
Those are directly related to the current source used to power the Mazzilli Zero Voltage (MZV) flyback circuit to evaluate the reach range of temperature reported as minimum comfortable (35°C) to comfortable (44°C)
Summary
A water heating system is defined as a device that transfers energy by heating water, regulating the water flow process, and operation temperature, among others.[1] In Mexico, this consumption represents around 27.2%,2 followed by Canada, approximately 22%,3 and the United States of America, almost 17.7%.4. Almost 75.34% of households consume fossil fuels in Mexico, and just 13.69% use solar energy.[5] Compared to Canada, reducing the use of fossil fuels by 59% followed by a 35% electricity use, showing a tendency to adopt green energies in the last years.[3] In the United States of America, only 23.4% of water heaters are fossil fuel, 45.6% are entirely electrical.[4] To select water heating equipment is necessary to be aware of different factors.
