Refrigerator Wattage Calculator for Energy and Surge

When a person intends to use a refrigerator with a power station or a generator, the person must account for the startup surge of the refrigerator. Even though many may look at the wattage of the refrigerator, the startup surge of the refrigerator can require significantly more wattage then the refrigerator requires while in operation. Should the power station or generator be unable to handle this startup surge from the refrigerator, the power station will shut off or the circuit breakers will trip.

Thus, the battery or generator that the person will use for the refrigerator will have to be sized according to the startup surge of the refrigerator rather than the wattage that is required for the refrigerator to remain in operation. A refrigerator do not consume electricity at all times while in operation. A refrigerator utilizes a compressor to help maintain the temperature of the refrigerator.

Why a Refrigerator Needs Extra Power to Start

Thus, the compressor must turn on and off in order to maintain the temperature of the refrigerators. The turning of the compressor on results in the startup surge of the refrigerator. The startup surge of the refrigerator is often significantly higher than the wattage that is required for the refrigerator to remain in operation.

Should the power system that is built for the refrigerator only account for the wattage that is required for the refrigerator to remain in operation, the power system may fail each time the refrigerator compressor attempts to start. The duty cycle for a refrigerator represent the amount of time that the refrigerator will run during a specific period of time. Refrigerators do not continuously run for 24 hours every day, so the duty cycle will always be less than 100%.

The duty cycle will represent the percentage of the time that the refrigerator compressor will be active. For instance, if the refrigerator has a duty cycle of 30%, then the refrigerator will be consuming electricity for only 30% of the total period of time. Thus, this value can help the individual to calculate the total amount of kilowatt hours that the refrigerator will use while it is running throughout the day.

The duty cycle will not always be the same for a refrigerator. This cycle will change based off how often the individual opens the refrigerator doors. Each time the individual opens the refrigerator doors, warm air will enter the refrigerator while cold air leaves the refrigerator.

Thus, the refrigerator will have to work harder to maintain the temperature of the refrigerator if the doors are opened more often. An increased number of times that the refrigerator doors are opened will result in an increased duty cycle for the refrigerator, leading to an increased consumption of kilowatt hours. Another factor that will impact the refrigerators duty cycle is the temperature of the refrigerators surroundings.

Refrigerators that are located within very hot areas will have duty cycles that are higher than refrigerators that are located in cooler areas within the home. If the air within an area in which the refrigerator is located is hot, heat will travel more quickly through the refrigerators insulation to the refrigerators interior. As a result, the refrigerators compressor will have to work harder to cool the refrigerators interior so that the temperature within the refrigerator remains the same.

The more that the refrigerators compressor has to work, the more that the refrigerator will run while in operation. Thus, high surrounding temperatures will lead to high temperatures within the refrigerator, leading to an increased duty cycle. Yet another factor that impacts the operation of a refrigerator is the amount of items that are placed within the refrigerator.

Refrigerators that are left empty will be less efficient at maintaining the temperature within the refrigerator than a refrigerator that contains items to be stored. An empty refrigerator will contain mostly air within the refrigerator. Each time the refrigerator doors are opened, the cold air will leave the refrigerator at a very fast rate, leading the refrigerator to have to cool the air that entered the refrigerator.

If the refrigerator contains items to store, such as food and liquids, the items will help to stabilize the temperature within the refrigerator. A refrigerator that is filled with items will have more stability in maintaining the temperature within the refrigerator, reducing how often the refrigerator will run its compressor. There are different types of compressors that is available for refrigerators.

Two of the most common types are traditional compressors and inverter compressors. With traditional compressors, the compressor is either on or off, indicating that the startup surge that is created is significantly high each time the refrigerator turns on. In contrast, an inverter compressor will vary the speed of the refrigerators compressor, allowing it to remain at a low speed if the refrigerators interior is at the target temperature.

Because an inverter compressor never completely turns off, there will be a reduction in the startup surge that that refrigerator creates. When selecting the proper power source for a refrigerator, there are two different metrics that should of been considered. The first is the daily kilowatt hours for the refrigerator, which will help to determine the cost of electricity for the refrigerator.

The second metric is the startup surge of the refrigerator. This will help to ensure that the power station that is used for the refrigerator has a peak wattage that is higher than the startup wattage requirement of the refrigerator. If the individual only considers the wattage specifications of the refrigerator, the power station may fail to start the refrigerator.

It dont matter how much power you have if you dont account for the surge. Most people would of missed this. It is a common mistake.
