A Study on the Control System of Electric Water Heaters for Decarbonization

Greenhouse gas (GHG) emissions have significantly increased in recent years as a result of population rise and the increase number residences, with high levels energy use homes household appliances. It is crucial to move housing industry away from high-carbon sources toward low-carbon order minimize greenhouse precaution. One most systems that needs be provided achieve efficiency electric water heater (EWH), they rank among top electricity consumers. In this study, double-tank EWH model was developed simulated at various tank sizes (100 L, 200 300 L 400 L) power ratios (1 kW, 2 3kW 4 kW) demonstrate efficiency. To obtain information for simulation analysis tanks, hourly usage 25 houses measured. The single-tank models created study were both run Matlab/Simulink environment an on-off controller applied, their consumption compared. Amounts also determined based on how much tanks consumed. has been noted amount GHG reduced because double uses less than single does. showed compared tank, dual produced 46.62% 45 W 47.51% 80 W.
