1. What is power consumption and how to convert power consumption units?
Power consumption is the amount of electricity consumed by an electrical device over a period of time. The common units of power consumption in life are watt-hour and kilowatt-hour, which can be expressed as Wh and kWh respectively, and 1kWh can represent the amount of electricity consumed by an electrical device running at a power of 1kW for one hour. Power consumption is one of the most common units in life, for example, the power company will use the total power consumption of your home to calculate the amount of electricity you should pay.
Wh and kWh, the most commonly used units of power consumption, can be converted to and from each other using a specific conversion relationship, which you can do by using the following equation, i.e.
1kWh = 1000Wh
For example, assuming that your device has a power consumption of 5000Wh, the number of kilowatt-hours your device consumes is 5kWh by using the above conversion relation.
Of course, there are other uncommon units of power consumption in life, larger than the unit of kilowatt-hours have megawatt-hours (MWh), smaller than the unit of watt-hours have milliwatt-hours (mW), and there is a certain conversion relationship between them and the kilowatt-hours, you can be converted by the following formula, namely
1MWh=1×10³kW
2. How to calculate the power consumption of the equipment?
Calculating the power consumption of a device requires two key data, i.e. the power of the device and the operating hours of the device. First of all, the power of different devices is different, such as the power of refrigerator is usually between 500W-1500W, while the power of portable air conditioner is usually between 800W-2500W, of course, you can know the power of your device through the instruction manual of the device.
Secondly, for the running time of the device, you need to know that different devices run in different ways, take the refrigerator, its internal temperature control system, when the internal temperature is higher than the set maximum temperature, the refrigerator internal refrigeration system will begin to work, in short, the refrigerator is intermittent operation, for this type of equipment, you can give them to install a monitoring system to monitor the running time of the device, so that you will be able to For such devices, you can install a system that monitors the running time of the device, so that you know the exact running time of the device.
After you know the power and runtime of the device, you can calculate the power consumption of your device. First of all, you need to clarify the physical quantities, power consumption can be expressed as E, power of the device as P, and runtime of the device as t. You can calculate the power consumption of the device by using the following equation, i.e.
E=Pt
For example, suppose your portable air conditioner has a power of 1.5kW, and your air conditioner needs to run for 6 hours a day, then substitute the above formula to get the power consumption of your portable air conditioner is 9kWh per day.
3. Role of Power Consumption Calculator
You only need to enter the power you want to calculate the power of the device and the average daily running hours, the calculator can be derived from the device’s daily power consumption, monthly power consumption and annual power consumption, of course, you need to pay attention to enter the power of the device column of the unit, you should know that the unit is different, enter the value is also different.
Power consumption calculator is a class of fast and accurate calculation of the power consumption of equipment, through this tool you can understand the power consumption of your equipment, which is conducive to your understanding of the power consumption of the various devices in your house, rational planning of the use of electricity in your house or install a solar power system, which is very important for you.
4. Summarize
You often calculate the power consumption of various devices in your daily life, through a deep understanding of the power consumption of devices, you can have a general understanding of the specific cost of electricity in your home, of course, if you want to avoid the complexity of the calculation, you can utilize the power consumption calculator, it will become a big help in your life.
