Thermal energy conversion formula: Q=860 kcal/kWh, Heat absorbed by water per minute: Q=CmΔt
(1) Heating 1 ton of cold water from 15°C to 95°C, each ton of water rises by 80°C. Calculation formula for heat required by each heating equipment:
Q=1000 kg × (95°C-15°C) × 1 kcal/kg°C=80000 kcal
1. Power consumption per ton of water for Yijia water boiler: (Electric-thermal conversion rate of Yijia water boiler is 98.5%)
A. Power consumption per ton of water for Yijia water boiler: 80000 kcal ÷ (860 kcal/kWh * 98.5%) = 94.4 kWh
B. Insulation power consumption of Yijia water boiler: Insulation 3 times every 2 hours, each time 10-20 seconds, insulation time for 12 hours is 180-360 seconds, i.e., 3-6 minutes. For a 12 kW water boiler,
the maximum insulation power consumption in 12 hours is 1.2 kWh
Power consumption per ton of water for Yijia water boiler = 94.4 kWh + insulation power consumption 1.2 kWh = 95.6 kWh
2. Power consumption per ton of water per day for ordinary float-type water boiler: (Electric-thermal conversion rate of ordinary water boiler is 85%)
A. Power consumption per ton of water for float-type water boiler: 80000 kcal ÷ (860 kcal/kWh * 85%) = 109.4 kWh
B. The insulation tube of float-type water boiler is 9 kW. Due to poor or no insulation material, the heating tube needs to be activated for more than half of the time in 24 hours. Calculated based on 12 hours of water supply per day,
the daily insulation power consumption is 12 kW * 6 hours = 54 kWh.
Power consumption per ton of water for ordinary float-type water boiler = 109.4 kWh + insulation power consumption 72 kWh = 181.4 kWh
Summary: The comparison above shows that Yijia water boiler : ordinary water boiler = (94.4/181.4)*100% = 52%
(i.e., Yijia energy-saving and healthy water boiler saves 52% electricity compared to traditional water boilers)
