How many kilowatt-hours of electricity does an air conditioner use per night? Electricity consumption of air conditioners and household appliances

In cold winters and hot summers, air conditioners are often the most important household appliances. In order to maintain a more comfortable indoor temperature, air conditioners are generally turned on for a long time. But every time it's time to pay the electricity bill, the extremely high electricity consumption and bill amount often make every family feel very distressed. So how much electricity does the air conditioner consume in a night? Below we will answer this question for you with a simple explanation.

Power consumption of air conditioners

In fact, many friends do not know the power consumption of general household appliances. Take 1P air conditioner as an example, the output power is generally 1200-3000W, electric kettle The power is 1200W, water heaters are generally above 2000W, and the power of small rice cookers is also around 800W.

The output power and input power will be clearly marked on the air conditioner manual. The output power (i.e. cooling capacity) of 1P air conditioner can reach 2500W, but the power consumption is by no means 2500W. The input power (i.e. power consumption) of 1P air conditioner is 850W-1000W per hour. Under normal circumstances, the electricity bill of 1P air conditioner should be about 1 hour. Around 0.4 yuan.

There are two common types of household air conditioners: variable frequency air conditioners and fixed speed air conditioners. Some households also have a trend of installing central air conditioners. For air conditioners with the same number of horses, the indoor temperature adjustment capability of a variable frequency air conditioner must be greater than that of a fixed speed air conditioner.

Of course, in terms of cost performance, the price of inverter air conditioners is relatively much higher than that of fixed speed air conditioners, and it is energy-saving in terms of functions. Another major advantage of inverter air conditioners is that they can provide precise temperature control. For people with air conditioning problems, they can also be controlled in a certain program.

Fixed-speed air conditioners are more energy-intensive, and the amount of current they draw when starting up is a certain amount of specified current. If it is turned on and off multiple times, it will consume more power. The heating and cooling capacity of the fixed-speed air conditioner is not very high. There is an auxiliary heating element inside, but the ratio is only 1, so it is relatively energy-consuming.

Variable frequency air conditioners

Inverter air conditioners are relatively energy-saving. They start softly when turned on, and there is no impact on the current and there is no waste. During operation, the inverter air conditioner will automatically change to low frequency to maintain temperature without shutting down. When maintaining the temperature, no power is consumed, and it is only one-third or even one-quarter of the specified power rating.

Calculation method of air conditioner power consumption

For air conditioners, power consumption mainly depends on the power of the compressor. Compressor power?=?refrigeration capacity?/? Energy consumption ratio, generally the energy consumption ratio of air conditioners is greater than 3, so the electric power of 1 horse is generally 735W, and the power consumption of 1.5 horses is 735?*?1.5 is about 1100 watts, which is about 1.1 kilowatt hours of electricity per hour, except for compression The machine, fans or other motors also need power consumption, and the total is only about 1.2 degrees per hour. The simplest way is to see how many kilowatts the input power is on the manual, which is the power consumption for 1 hour.

How much electricity does an air conditioner consume in a night? I think everyone should have a simple answer to this question now. In the same situation, a better air conditioner not only has advantages in environmental protection and functionality, but also It will also perform well in terms of power consumption. Therefore, when we buy air conditioners, we must pay attention to this content. At the same time, we should not overly believe in the slogans of manufacturers when selling home appliances, such as "only consumes 1 kilowatt hour of electricity a day." Make judgments based on the level, etc. to avoid buying products with excessive power consumption and poor energy efficiency levels.
