According to the power of electrical appliances, how to calculate their hourly power consumption? When we calculate the power consumption of an electrical product, we calculate it by its electric power, that is, how much "work" the electrical appliance has done per hour. And this work is obtained by multiplying the current (ampere) by the voltage, so the calculation formula of electric power is:
W = av (work = current x voltage)
Some electrical products will be directly marked with W number, while some electrical products may be marked with current number A because they can be applied to many different voltages (that is, the V part in the above formula is not a constant value). When calculating the electricity bill, the hourly electricity consumption is 1000W degrees. Therefore, if the electric power of an electrical product is 2000W, it consumes two degrees per hour; If the electric power of an electrical product is 500W, it consumes 0.5 kWh per hour.
So what is the power consumption of electrical products? According to laws and regulations, power specifications must be posted somewhere in electrical products. Look behind your computer screen.
Small products such as light bulbs can be printed directly on it.
For air conditioning, it is generally possible from 6,700 W to several thousand W depending on the tonnage, and there is no need to directly convert the electric power W. If marked with the current number a, insert the formula W = AV calculation. For example, if the voltage in Taiwan Province province is 1 10V, and the computer screen current in the above example is 2A, then "W = 2x 1 10" and its hourly electric power is 220W.
Note: In fact, when the voltage is different, the current number will change accordingly. This example only simplifies other considerations for the convenience of explaining the formula, so please pay more attention.
If you don't care about losses and errors, you can calculate them directly.
The kilowatt-hour of electricity consumption is actually the electricity consumed by electrical appliances with power of 1kw 1 hour.
For example, a 200w computer only uses 1 kWh for 5 hours.
A 3000-watt motor uses 3 degrees of electricity an hour.
How to calculate the hourly power consumption of electrical appliances with power of 100w? Because: 1 kw * 1 hour = 1 kwh.
So:100W (0. 1 kW) * 1 hour =0. 1 kWh.
Degrees, that is, kilowatt hours, are the electric energy consumed by 1 kilowatt power appliances 1 hour. 100W means 0. 1 kw, and 1 hr electricity consumption is 0. 1 kw * 1 hr =0. 1 kwh.
How to calculate the hourly power consumption of electrical appliances? The rated power of electrical appliances is multiplied by the hours of electricity use. 1000 watt appliances, electricity consumption for one hour 1.
How much does the air conditioner consume per hour? How to calculate it depends on how many watts the cooling and heating power of the air conditioner is, the size of the room, the sealing and insulation situation, the outdoor ambient temperature and the degree of indoor temperature adjustment, which have great influence on the power consumption.
For example, an air conditioner with a first-class energy efficiency of 2500W is suitable for a room of about 12 square meters. The cooling input power is 650W, and the average hourly power consumption is generally between 0.4 and 0.65 degrees. Adding heating and auxiliary power, the average hourly power consumption is about 0.5- 1.3 degrees.
IT equipment power 2300 watts per hour power consumption quality answer
"Electricity" is electric energy.
Electric energy refers to the work done by electric field force (or power supply force) in a period of time, and the unit is kWh;
Electric power refers to the work done by electric field force (or power supply force) in unit time, and the unit is Watt (W).
The relationship between electric energy and electric power is: electric energy = electric power × time.
"kWh" per hour (consumed electric energy) = 2.3 kW×1h.
= 2.3 kWh = 2.3 degrees
The power consumption of the 3800 power soymilk machine is 1 kW 1 hour. If the soymilk machine works continuously for one hour, 3.8 kW per hour is 3.8 degrees.
Power: ≤ 320VA
≤320VA equals ≤320W, and then divided by 1000, the hourly power consumption is ≤ 0.32kwh..
How to calculate the hourly power consumption of 900w small solar water heater? Theoretically, it is 900/ 1000*h, that is, 1 hour, 0.9 kWh.
One-degree electricity is 1 kWh, which means 1000W for one hour.
