There is a quite simple method to determine how a lot power your house home equipment are utilizing. I am not a math genius, and I can
precisely decide how a lot power every equipment in my house is utilizing 엘지정수기.
The system is:
(Wattage × Hours Used Per Day ÷ 1000 = Each day Kilowatt-hour (kWh) consumption(1 kilowatt (kW) = 1,000 Watts)
Decide the annual power consumption by estimating what number of days per 12 months you utilize the equipment. Then, you possibly can determine the annual value by multiplying the kWh through the use of your native utility’s kWh fee.
This is an instance of one thing chances are you’ll use often – a private laptop and monitor.
(120 + 150 Watts × 4 hours/day × one year/12 months) ÷ 1000 = 394 kWh × 8.5 cents/kWh = $33.51/12 months
Regulate the numbers to what you utilize. If you do not know the precise figures, make an estimate.
Many home equipment have the wattage stamped someplace on the unit itself. It could be on a steel plate together with the
producer’s serial quantity. If you cannot discover the wattage, chances are you’ll discover the quantity of amps the unit consumes. In the event you discover the amp consumption, multiply it by the voltage utilized by the equipment. For many home goods, it is 120 volts.
Nevertheless, your electrical range and dryer are normally rated at 240 volts.
Watch out for a situation generally known as “phantom load.” That is when home equipment proceed to make use of electrical energy even after they’re turned
off. Some widespread examples are your VCR, TV, stereo, laptop, and lots of kitchen home equipment.
You’ll be able to forestall phantom load by both unplugging the equipment from the wall socket, or you possibly can plug it right into a power strip.
Flip off the power strip while you’re achieved utilizing the equipment. This can avoid wasting cash in your power invoice yearly.
This is some typical wattage rankings for widespread family home equipment:
Espresso maker = 900-1200
Garments washer = 350-500
Garments dryer = 1800-5000
Dishwasher = 1200-2400 (utilizing the drying characteristic vastly will increase power consumption)
Garments iron = 1000-1800
Microwave oven = 750-1100
Radio (stereo) = 70-400
Fridge (frost-free, 16 cubic toes) = 725
Televisions (coloration)
o 19″ = 65-110
o 27″ = 113
o 36″ = 133
o 53″-61″ Projection = 170
o Flat display = 120
VCR/DVD = 17-21 / 20-25
Vacuum cleaner = 1000-1440
Water heater (40 gallon) = 4500-5500
Now that you understand how to calculate power consumption of widespread home equipment in your house, it is simpler to determine which of them you need to maintain turned off as a lot as attainable to save lots of power.
